Post Title: Barts 1973 LJ Torana VH41 Twin turbo project
Posted by: Bart at 7:44 AM 5/25/2008

This is going to be a fairly big post with lots of pics.
The very first thing i did was build a chassis jig to bolt the car onto as i had to cut out/replace the sill pane;s/rockers
The jig was to ensure the chassis didnt move



Cut out rusted inner sill/rocker panel, fabricate a new one.

Inner sill, outer cut out

First of many trial fits

Front nose clip removed and the lower sides were rusted out

Sills and front pillars removed and off to the sand blasters. Drilling out spot weld is a real *****

Trial fit

New sill panel, I had to round off the end of it as per the original.
One end of sill panel maked up


Cut and tacked



Dollied to shape, this was done before the full weld.



Door gap way off

Better

Befpre i welded the outer sill on i prepared the inners with POR15, made sure this bugger wont rust for a while, also added drain holes on the bottom of the sills

Old and new outer sills on its inside

Had to repair the rear seat shelf, both corners were rusted so i had to fabricate new corners, cant get reproductions unfortunately.
Drilled out the spot welds, what a ***** of a job







Now the fun Part, fitting the VH41

It wont quite fit between the chassis rails, but the rails have been modified but not in these pics yet


Time to fabricate the engine mounts
Motor in position to front cross member


Cut out template for engine mount

Mount taking shape









To make more space between the rails i had to modify the cam covers


To make more room for the exhaust manifolds i had to fabricate the to front suspension mounting shafts. The originals had a curve in them which took 3/4 inch of space which i desperately needed.
The new cross shafts are 4340 chrome molly.


I later opted to go for adjustable front top suspension



Fabricating the sump, this wasnt done by me

I couldnt find a suitable loction to tap into the main oil gallery/oil pick up so i used the original and mad a fiting, this will lead to an external oil pick up


Engine adapter plate


Fuel tank fabrication

Wow man! thats a lot of work. Eager to see the rest of your pics.

Nissan makes this Torana? I dont think Ive seen that before. Was it sold in the US?

Posted by: Bart at 9:33 AM 5/25/2008



No the Torana was made by General Motors Holden GMH in Australia.
The usual conversion is to use a Chev or Holden V8 but i decided to go Nissan VH41

Sweet!

Im now obsessed with those engine mounts!

And everything else

I cant wait to see about the brake pedal setup. Something like a reverse swing wilwood setup?

I want to put a 1uz or vh45 into a gemini just for fun, but the only problem is the booster and master cyl.

No i didnt use a Willwood setup, funny you should mention that as i was that close to using a Willwood or Tilton floor mount, but i was steered off them as they were apparently a little too different to use, and advised if i use then i must lower the drivers seat, this may have caused problems with the engineers certification.
Basically i used the Torana brake pedal box but since i changed the brake and clutch cylinders i had to fabricate the the linkages/clivises with a bronze bush. The brake booster basically had no room on the firewall as the motor is quite big and the car is quite narrow lol, so that was relocated in the boot/trunk (American terminology ) (Remote booster)
The engine mounts are made from round pipe and 4mm steel plate.

That car looks scary light. A trunk mounted booster? Awesome!

Posted by: iViLe at 3:24 AM 5/27/2008

Hmm very interesting boot mounted booster!

In a magazine i have it has a torana the same but has a tilton reverse mount pedal setup under the dash, cant really see it very well, but i think it has 4 pistons calipers all round so wouldnt need a booster, yeah floor mount thats a little wierd lol.

In my chev i run a wilwood pedal assembly with the 2 wilwood masters and 4 pistons wilwood calipers all round and it stop fine, dash headbutting fine actually lol. So i was thinking that for my gemini if i do it right i shouldn't need a booster, just some good calipers and pads!

Good luck!

SWEET build! I can't wait to tackle a project like that one. Ground-up builds have to be one of the most rewarding things in life.

I can't help but chuckle at that chassis dolly shot. Looks like a gurney ready for a patient in the ER.

VERY creative engineering--keep up the progress!



Post Title: Re: Barts 1973 LJ Torana VH41 Twin turbo project (z1 zonly)
Posted by: Bart at 6:47 AM 5/29/2008



Basically had to make up an aluminium template, to make a steel bracket to weld onto the firewall, then the brake cylider bolts onto the bracket.
It took a bit of stuffing around to get it right but it worked at the end.







Had make a brake/clutch pedal linkage to the cylinder push rod. The linkage/clevise was left over 4340 chrome molly. Made up a bush from bearing bronze which is press fit, this hopfully stops any squeeking.




This the clutch cylider (verticle) mount. I welded a stiffener plate to stop it flexing while pressing the clutch.

I hear you there... No one wants to publish their mistakes.

This is an awesome project and I love the pictures. I love keeping tabs on all the crazy VH projects that are going on.

This sub-forum has some great craftsmen and mechanics - even if they're just garage warriors.

Keep up the good work

Just putting together the fuel tank here

Fabricated fuel tank lid with gasket to allow fuel foam inside the tank

Modified oil filter housing to feed the turbos

Brake booster in the boot/trunk behind the back seat, the braket i made up isnt finished but will be ok for now

I used a flexable stainless steel tube for the vacum which can be seen under the booster

300ZX Fidanza fly wheel which is modified to take the VH41 ring gear and re-drilled to take a 350ZX clutch which all has been re balanced.

Sump is on with aluminium dip stick tube. The dip stick tube is left over aluminium fuel line.

*** end

Modified spigot bush

As shown else where on this forum i had to extend the clutch bearing holder with 6061 aluminium

Hey Bart,

Few questions:

have you spoken to a compliance engineer about your transmission adapter plate? what did they say?

Who made it for you? there are no vh41 plates available that I know of?

What transmission are you using Z32? If so why the Z33 clutch?

Finally what company did you get your VH41 from, just the engine or a cut?

Cheers

Posted by: Bart at 11:11 PM 7/5/2008



I wont be saying anything to the engineer about the adapter plate
I will get you the contact on the guy who made it he has done the same conversion, hw is in Perth, its an RB20t gearbox, which is not strong enough so i will be using a RB25t gearbox later
The 350ZX pressure plate has more pressure than 300ZX and is softer on the clutch peddle.
I got the motor from a import company in Sydney called SSS Automotive
Their are a few different versions of this motor mine is apparently the better/best one?? But if you get one from Japan they only have the best ones available i think, as in the US they had different versions which wernt as good, i think if you ask Mettler he can confirm this.

Interesting, I think if i go with the adapter plate route, I'll have to review it with my engineer, unfortunately I think they will notice such a thing in my roadworthy/mod. inspection.

I'm thinking I might go the Z32-TT 5-speed, those rb boxes are so damn expensive, but the contact details of the guy making the plates would be fantastic.

I've contacted SSS Automotive, did you get yours in a front-cut? What did you pay?
The "good" JDM vh41de's came in FGY32 Chassis (e.g. Cima and Related) up until the beginning of 1996. The next model is pretty much the same as the US VH41DE and was in the FGY33 chassis.

I've had trouble finding a decent priced cut, i had to turn one down last year because I didn't have the $$$ in my account then.

Some guys here have used aluminium but I prefer steel as it’s more durable in the thread area and durable over all

Hey,

I was just wondering where you got the parts to make those adjustable upper control arms, as my Chev uses the same old shim setup, so adjustable ones would be 9999x better!

No worries, this setup was basically an experiment to see if i can use them on an LJ, i got them from the good ol USA, and of course they dont have LJ Torana's there, so this was a mix and match, of off the shelf parts, the company is called SPC Performance, i had to do allot of measuring and heaps of emailing to get it right before i did the actula order. I think for the chevy tey may have them off the shelf ready to go for you. They were appro $400 delivered, but yeah real good quality stuff. They also do allot of setups for the Jap car, 300zx's etc.

what turbo's are you using, I am amazed by all of this.



Post Title: Re: (Kalypso123)
Posted by: Bart at 6:58 PM 9/20/2008



The turbo's I'm using are two GT3071R's, not installed yet as I just got it going, the manifolds are bolted onto the motor so its just a matter of bolting the turbo on but I still have to make up the exhaust pipes, the car is still at the mechanics I will pick it up today.
There was a bit of drama, typical of this project, we couldn’t get oil pressure, we believe it was because the custom oil pick up was just full of air since the engine never ran with this setup so we pressurized the sump with some air (5psi) through the dip stick tube and filled the oil filter and lines with oil and it worked, we got good pressure.
Custom clutch works well
Custom brakes work but the pedal goes down too far so may need more bleeding.
The custom fuel tank and pump/line setup works really well also.

Post Title: Re: (Carl H)
Posted by: Bart at 8:38 AM 9/25/2008

Its only been a couple of days but yeah they should be bolted on this week end.
Unfortunately one of the oil lines are braided rubber hose and is very close to the exhaust manifold, (my fault) so i was advised to change those lines to steel so im fabricating steel lines at the moment.



Post Title: Re: (Bart)
Posted by: Kalypso at 7:26 PM 9/25/2008

now that you've made the exhaust it seems like you'll be rerouting them back up to the exhaust turbines...

I am anxious to see how the turbo's will play into all this.






Post Title: Re: (Kalypso123)
Posted by: Bart at 1:46 AM 9/26/2008



The oil lines im talking about go from the two outlets in the block where originally there was the oil filter housing. I removed the oil filter housing and mouted it in the engine bay, you can see in the vid the oil filter is standing up. At the moment i have braided lines going from the block to the filter housing, near the block area the lines are very close to the manifold, this section of line i will replace with steel tube, then attatch the braid on that where it clears the manifold

Post Title: Re: (squidgymop)
Posted by: Bart at 8:05 AM 10/5/2008

Thanks mate
I didnt use a 350 as its illegal in a LJ.
I wanted a V8 with turbos, so a 308 with turbos is illegal, i could have used a 253 with turbos but i dont like 253 very much so a VH41 with turbos was the choice i had.

turbo tight squeeze




Post Title: Re: (Bart)
Posted by: tmorgan4 at 5:37 AM 10/7/2008



Nice job squeezing the turbo in there! I had to go back and look through pictures of my build to figure out what that inlet was for. It looks like that valve is part of the EGR system (It's been so long since I've looked at this, I'm a little embarrassed I'm forgetting this stuff already!) so if you aren't keeping the EGR system, plug it. I found a block off plate that fit perfectly on the bottom of my OEM Pathfinder VG33 manifold. Other companies sell the block off plates, or it seems like you've got the means of making your own.

Sounds good to me.



Post Title:
Posted by: Carl H at 7:34 AM 10/7/2008

that is the idle air control valve...good to have for idle...not egr.
if you're on a map system then you need to just put a filter on it, else needs to be routed into the intake track before the throttle blade.
quick word of advice tho, that pushfit aeroquip hose is great to make hoses on the fly but it does not stand up to heat worth a damn, either insulate the crap out of it or replace with ss braid...my oil hose almost exploded due to heat issues and has since been replaced with ss braid.



Post Title: Re: (Carl H)
Posted by: tmorgan4 at 3:20 PM 10/7/2008

Is his Idle Air Control Valve in a different place than mine? I did realize that his valve looked differently (mine was the little flying saucer looking thing) but you can see my IACV on the back of the intake.



Post Title: Re: (Carl H)
Posted by: OutToWinPAHC at 3:53 PM 10/7/2008

I know nothing of these motors but IAC's are a passage way to bypass the throttle plate. A piston or solenoid controlled by the ECU open and closes the passageway. It is used to idle, basically its what a choke used to do on carb cars. IAC are located on the throttle body, not on the intake usually. I don't see any spots to land wires to control an IAC on that. It appears to be EGR related

From Nissan Parts.org

1) Egr valve 2) Egr valve Gasket 3) Tube
4) Egr temp sensor 5) Bpt valve 6) Bpt valve Bracket
7) Vapor canister 8) #1 Hitachi 9) Solenoid valve #2
10) Oxygen sensor Right


It looks to be the EGR valve. Hope I could help you out some.

This is really puzzling me...It doesn't look like the EGR or IACV valves! You can see my IACV valve on the back of my intake manifold in the picture above.

Any chance you might be able to get another picture (maybe a few) of it Bart? I'd really like to find out what that is.



Post Title:
Posted by: XJared at 5:40 PM 10/7/2008



thats the inlet for the iacv...notice the adjuster screw directly on top of it?



Post Title: Re: (XJared)
Posted by: tmorgan4 at 5:58 PM 10/7/2008

Yeah I did notice that screw which made me curious. Could this be a difference between model years? Both the IACV on the VH45 and my old VG33 used the same, identical 4 bolt pattern. Not a 2 bolt like I've got on my manifold. All the diagrams I've seen (like the one a few posts up) show the EGR valve bolting up where Bart has this "mystery" valve.

Look at pictures here: http://forums.nicoclub.com/zerothread?id=33796

Posted by: Mettler at 6:18 PM 10/7/2008



tmorgan4, Bart's engine is a JDM VH41DE, the hoses in and around the manifold are completely different to the VH45DE... this may explain your confusion

The one Bart was pointing to does indeed go to the intake tract before the throttle body.

[edit]Argh I posted up some pics but realised they won't be of any help[/edit]

The JDM VH41DE has a cast aluminium bend bolted to the front of the throttle body, and the bend has a tube coming off it for that hose.



Post Title: Re: (tmorgan4)

I know when i block the outlet and adjust the screw it affects the idle speed.




Post Title: Re: (Bart)
Posted by: Bart at 6:26 PM 10/7/2008

So should i just plug it into the inlet before the TB? Mettler
I cant remember there being a bend. I will have another look, maybe the bend is on the original 3 1/2" dia rubber hose which goes on the TB?

THANK YOU METTLER! I guess I could have looked at the title that does in fact show he's using a VH41! I forget sometimes that not everyone here is using a 45.

if you're using a map based ecu no need to plumb it into the intake track, just put a small filter on it and reconnect to the ecu to keep a nice idle.

^ What he said! It's just the hose for the idle control, I forgot what you're doing for an ECU, but CarlH has already summed up what you need to do in either case, whether you're using MAP or MAF _b

I can take more pics. Im using a programable after market ECU, using a MAP sensor. I have another air signal line going to the MAP sensor on the other side of the manifold. A filter sounds good but no way i can feed another line from this outlet to the ECU

I may be mistaken in that it goes on that bend... I remember that bend has a tube coming off it for one of the bigger hoses, but I also remember there being a large fitting on the underside of the black plastic bend coming off the airbox. I'm not using any of that crap on mine though, got a custom bend in there :D

Just take that whole idle control unit off and make a plate to blank it off.
Some aftermarket ecu's dont control those idle solenoids very well.

Im running a rb30det but retained all the rb25det cold start and idle stuff.

My tuner advised me to blank it off, then set the idle with the throttle stop screw. I still have the cold start valve hooked up, so when its cold it idles around 1050rpm then drops down to 800/850 when warm.
All you need to do is feed 12v off the injector feed to it so it only gets power when the engines running, the valve heats up and closes. I think the v8 also has this part.

BTW, nice job Bart, been following it with interest

Hey guys
I did a search on wiring up the alternator and found a few unanswered threads except a couple which wernt entirley clear.

I connected the main thick cable to 12v.
Just wondering the 2 small wires on the plug, my guess is one goes to a cluster light and the other to 12v?
The problem im having is battery is not charging.
Thanks guys

the white/red wire on the alternator plug is normally your alternator light...as far as charging goes be sure the grounds and the battery connections are good...a friend had a similar problem where the car would start and run but would not charge even tho the alternator tested out to be good.
problem ended up being his grounds were on painted metal and poor connections, moved to unpainted metal and proper connections problem went away.

Page 17 of http://www.nicoclub.com/FSM/Q45/1994_Q45/el.pdf

Indicates that the second wire from that connector, the white one is fused over 10A to the battery and the other goes off somewhere to the interior of the car.

I would hazard a guess that one of them is to enable the field coil so the alternator will actually start generating power. There is the resistor in there as well.

I had a fiddle with it tonight but it got late and i didnt want to start it with no exhaust.
The white/red is going to 12v when ignition on and 11.9v when engine running.
Green/yellow not connected. Yet

So after reviewing the FSM (which I should point out is the USDM vh45, but as far as i can tell pretty damn similar) again and having some practice reading them today.

One of these wires (White in the FSM) wires goes to constant +12V.

The other goes through the "Alternator 'L' Resistor" and then to a +12 from the car's 'ON' position.

The diagnostic display has a connection to each side of the "Alternator 'L' Resistor".
No mention of the resistors value.

Futher more, if you take the FSM's perspective, in your case, the G/Y is S and the W/R is L. Where S is battery voltage sense (fused to constant +12V) and L is charge waring light. From here: http://www.autoshop101.com/tra....html

However then there is no ignition 'on wire' in this situation. What I assume is that the warning light and the ignition occur on the same line. By measuring the voltage on each side of the 'L' Resistor the diagnostic unit is able to determine charge state. This line is also connected to switched +12 so the alternator can figure out when the car is switched on.

Need to track down a Alternator resistor perhaps?

..offtopic
forgot to ask, Bart, can you take a photo of one of the coils, the connector of the coil, and some detailed photos of your ignition transistor and connector for me?

Thanks

The problem you are having is as follows, you need to put the cluster bulb cable on an actual bulb with power on the oppisite side or add some sort of resistance to it, the bulb completes the circuit here and the alternator wont charge with out it. I chased this problem down for a week and went thru two alternators before i figured it out.

If you connect both wires to power it will charge however it wont charge correctly, this would be a temporary fix just to get by.

As for the resistor thats stated in the fsm i have been thru the entire q45 chassis harness and engine harness and have found nothing that resembles a resistor for the alternator. It either built in the alternator or into the ecu.

This is probably too late but I didn't use any idle control at all! The ecu (Autronic) does it all without the need for even TB adjustment. We were going to adjust the TB if needed but it has proven to start in any weather, including sub zero Rotorua in the middle of winter, without any issues.
To give you an idea of how unneccassary it is, I can cold start the motor and sit a glass of rum and coke on the manifold while it is still at fast idle. It does not get shacken off even once the idle slows after 30 seconds or so!

In my book that is a pretty relevant test to!

Tack welding the exhaust and the rear muffler, I have tucked the muffler up and will use turn down exhaust tips. You will see the muffler even less when the car is on the ground as the car is up on stands.



Bit of welding

Bit of paint

This is my atempt of an Xpipe, I dont like the way it turned out, i will modify it before i fully weld it so its more of an X shape, but for now im running with it the way it is so i can complete the rest of the exhaust.

What you have done here is almost exactly what I did to start with and it caused oil pressure to be about 30psi!
I modified it so that I had the factory bypass valve at the oil pump and that solved the problem. I hope this doesn't happen to you but be prepared for it. I'd try what you have but keep a close eye of the pressure.

Its actually very subtle to drive, in fact too subtle, previous engine conversion in this same car was an RB30t, boosted to 16psi and it performed better. But then currently on my VH41 my trubos are producing vertually no boost or very little as i have the waste gates set this way at the moment, and the exhaust manifolds are fabricated log style which are not great.
Will have to see what it produces when boosted to 15psi.
Still have to find a couple of JDM VH41 cam covers

So where do the valve covers actually leak from?

They leak from where its been welded. Its not very good alloy to weld.
But im in the begining of making carbon fiber ones, just about to make a silicone mold of the flange area of the valve cover since this is the most important part to seal. The top of the cover (mold) will pretty much be free hand made of foam keeping in mind it will be semetrical to the other valve cover.
Wish me luck, im going to need it

Hmm I see now, too bad you cant just seal it up with some kind of sealing agent, paint, etc.

Well good luck!

So interested to see where this goes.

I'd buy a set!

Hey Bart, Whats your engine SN? I'm trying to figure out the year of mine.

Bart. just curious being a LS guy. Sometime we pull heads from the larger displacement engines for the smaller engines in our series. The benefit is larger runners, and higher CC combustion chambers for boosted application on a budget.

Do you VH41 guys ever swap the USDM 4.5 heads? Seeing your going to boost her it might be a fairly cheap mod that can also solve the valve cover issue.

Hmmm I see where you’re going but this may require a bit of trial and error. It may be worth while but im pretty set on carbon covers at the moment.
But thanks for the "out of the square idea" I appreciate that, reason i spend so much time on here.

I would love to sell a few sets
Just got to make a set of my own and see how it performs
I wont sell any until i know it works 100%, that is it looks good, and dosnt leak, so i will pressure test them before thinking of selling any.

Hey Bart,

Do you still have your VH41 Automatic bell housing around (not in use?)

I am trying to get hold of one.

Thanks

Hey guys
Perhaps this question is more towards the Aus/NZ/Jap guys as i have a JDM VH41, I would like to replace the rear crank seal.
Anyone know if this seal is the same as other nissan engines? Such as VH45, SR20's etc?? Part number would be good too
Thanks
Bart

J N K N G 0 1 C 1 N M 2 0 3 2 1 4

they are both zero's but i cant tell if the last '1' is a 1 or and i when you get on the phone they will tell you if its good or not

Well its been over 3 and a half years (i think) building my LJ, i went for the engineer certificate and registration, And it passed. Thank christ its over.
So im happy and relieved.
Oh got to thank everyone who helped and a encouraged me, and advised me, there have been times when i was stuck but there was usually someone here who could help.

Unfortunately the car isnt fully restored and it shows in these pics, but the idea half way through the build was to complete it to the point of engineering and rego and here it is all engineered and regoed. Since half way through the build we/I was told, and most of us in Sydney heard the RTA (Roads and Traffic Authorities) will change the modification rules so i had to rap it up early. Has some primer etc on it but you get the general idea, it has potential to be a real nice looking Torana with some body work and paint which will come later.


Since my camera went flat on me i couldnt get close ups and detailed pics
Heres a little peak of the passenger side turbo, GT3071R with K&N filter and a -8 Speed flow fitting hanging down to drain the oil, the oil drains through this and sucked through by a gear type electric oil pump, into the sump, the other turbo shares the same line/pump. The pump is used for drainage as the turbo is below the line of the sump i.e. not gravity drained

What are the changes happening in NSW for modifications?



Post Title: Re: (Chrispy300)
Posted by: Bart at 6:06 PM 10/13/2009

NSW or Nanny State Wales plan on restricting the engine capacities in engine swaps. I think they have done this all ready in QLD? Its supposed to be a national code, but seems very blotchy, lots of mixed messages from the RTA, cant get a straight answer from those people.
I think in my case with the rules yet to come, the maximum turbo engine size would be 3.0liters.

Oh yeah, I've been working off that code. I quite like it, works well for the Z. It's the vehicle mass times 3 for the maximum displacement for a FI engine. I'm guessing that the Torry is pretty light compared to my 1500KG Zed :p

The interesting thing is it all depends on how it is interpreted. According to the regs there is no reason why you can't get a NA motor (such as the LS1) into a 300ZX (or whatever) under the NA engine swap mod cose, then at a later date get it turbo'd/supercharged under the forced induction installation mod code. Although it is over the displacement per weight, there is no clause in the forced induction code that limits the size of the motor at all.

Factory carbon canister I believe... I'll check it out for you properly if it doesn't turn out to be that.



Post Title: Re: (Mettler)

Thanks mate that would be great
Maybe i can plumb it back into the intake? As i have no canister

I just checked out an old pic of a cima engine bay and can confirm that it does go to the carbon canister... and I'm pretty sure that they're under vacuum from the intake to keep the system closed loop.



Post Title: Re: (Mettler)
Posted by: Bart at 9:51 PM 10/26/2009

Thanks Mettler for taking the time to check for me.
So i guess i can just block it off?
Or plumb it back into the intake?
Im guessing block it.



Post Title: Re: (Bart)
Posted by: Kirby260 at 1:38 AM 10/27/2009

Hey Bart,

Checked one of my engines, line plumbs into the intake already behind the throttle. Just block it off. The little green solenoid next to it is the lift solenoid for the carbon canister.

Hey guys, im trying to do a rough tune on my engine VH41 trubo, just need to know what the fuel pressure should be at the regulator while the ignition is turned on with fuel pump activated (just before starting engine) and fuel pressure while idling/engine running.
Thanks

Should be around 43-45psi w/o vacuum when idling. Ive found fuel pressure is higher when the engine is cold. I always take a quick drive then set according.



Post Title: Re: (DrifterProdigy85)
Posted by: Bart at 3:17 AM 11/5/2009

Thanks mate it works fine on 43psi.

So whats your HP goal with the car? You think youll find any restrictions with stock cams and intake manifold? I cant wait to see the tq numbers since this is something im really looking into doing for my 240sx except using a VH45 and twin 60-1's.



Post Title: Re: (DrifterProdigy85)
Posted by: Bart at 6:02 PM 11/5/2009

Im not expecting big numbers but i would be happy with 450hp.
Its on 5 psi boost and has log style exhaust manifolds which are inherently restrictive. So 450 would be ok as a start.
Later i would go for bigger injectors, custom inlet manifold, and extractor style exhaust manifolds.
