S12 VH45DETT Build-Up

[Ezekial]

just move the master cylinder, remote master cylinder??

unfortunately nobody can give me any insight into how this is done ...

the 45 is definately the better choice ... lower compression, bigger capacity, etc ...

But its just becoming a headache

[Bart]

I think Castlemain rod shop sell them as a kit if they dont they would probably know who does.It basically cosists of a master cylinder mounted to the firewall then that goes to the slave cylinder and the slave cylinder is attached to the booster.Or just do a search on remote brake boosterCorrect me if im wrong anyone.

I think you would be better off with a VH41. They are an evolution of the VH45 and have better heads(the 45 has siamese ports). You also can get a sump for the 41 which lets you run 4 wd . This sump has a hole through it for a transaxle and mounts for a diff. This sump will not fit the 45 as the starter is on the opposite side and there are quite a few differences between the two engines.e have an engine builder locally who has built a number of N.A. motors for the stock car boys and we have just finished a 830 hp engine (41) for a jet sprint boat. A friend of mine has put a VH41 into I think a gazele so he will know all the pitfalls Will e-mail you

Way to promote your product

Could you give us some prices?

i am doing a Vh45de conversion

i believe the motor was no wider than 800MM at maxsumwhere in mid 700milimeter i believe, can check when i go to mechanics next

i plan to do a Twin turbo setup (if there is enuf space!!!) but im gona get car all running, and certified, and suspension/ brakes setup up nicely before i seek too much power

i saw a guy here sugesting gtir T28 turbos, they wont flow to 400flywheel HP, infact 300flywheel HP is probably closer to the truth

and i will be running a manual 5spd gearbox, i have got a price of 150NZD$ (approix 75USD) to chop the bellhousing from the auto, onto my 5spd so thats nice hopefully it handles the torque (ive heard actual torque figures are close to 451NM factory??)

anyways, im looking for any and every info i can find on the VH45de (especially how much they can handle)

cheer, matt

Doing pistons and oil cooling jets for them too? Might look at AGM posts, but he is still sorting his out.

i think i suggested that to somebody at one time. it was just a guess. glad you know for sure and provided that info. now to track down whoever i said that to originally and tell them. come to think of it, that may not have been me...i dont remember.

That's intense.

[Chezedik]

What do you do for mounts, are you fabbing them? How hard has this been so far? Do you see any problems with left hand drive? If this isn't too rough, then I will sell my S13 and get an S12.

[Ezekial]

That's intense.

yes. i scrapped the twins and now have a GT42RS 53 trim 1000 hp turbo.

It fits nicely in the drivers side (RHD vehicle) nicely ... just behind the headlight ... no real room for a filter though given the 5" inlet

Mounts are fabricated yes ... easiest being the gearbox mount which is a cut and shut infinit s12 job ...

Also ... the steering rack is really the only issue ... and lack of room for power steering pump, alternator, etc ... alternator had to be moved on top of the engine like on the VH41's ...

There is quite alot of room for exhaust manifolds to run across to behind the right hand side headlight ... the standard auto fits in the tunnel ...

what else? the heater has to be removed and new lines run ...

the wiring from the right hand side inner guard has to be completely removed and re-run around to the left or some left inside the car in my case ... otherwise the exhaust will fry it ... it will run through the inner guard ... this is for big single turbo

I believe there is a bit more room in S13's though ... i didnt want the extra weight though ... or the IRS

hey man can u tell me what mods u have on ur charade?i also own one in nz

Its a CB70 3 cylinder 1 litre DOHC engine from gtti charade.

276 duration camshaftsadjustable cam gears320 hp garrett turbo (off s14 series 1 sr20det engine) with 180SX CA18DET T25 0.49 A/R exhaust housingcustom exhaust manifoldtial 38 mm external wastegate with screamer pipe4agze injectors53 mm throttle bodyadjustable fuel pressure regulatormicrotech lt10s with 28psi map sensorevo 5 intercooler3" dump pipe 2 1/2" exhaust

standard bottom end, standard head casting (no porting or port matching)

it made that power on 28psi on 98 ron pump fuel on a REAL chassis dyno not a hub dyno ... without the adjustable cam gears and with some issues which i have since sorted out ...

the reason i stress the chassis dyno is because if i was to put it on a hub dyno you could increase that figure by 30%

you're from NZ? there are a few guys in NZ who have got microtech ecu's off me

[Ezekial]

well ... more news

decided to go for a 2 speed powerglide transmission with transbrake, custom bell housing adapter and 3500 rpm stall thanks to a custom torque convertor!

guarenteed it wont break up to 1000 hp ... i didnt opt for the $300 extra input shaft to warrant 1600 hp ... i dont think i will EVER see that much power!

got a 600x300x100 mm intercooler also ... now just have to get custom head gaskets made. I've decided to drop the compression to 9.0:1 and try for 20psi ... should net me about 750 engine kw

[JDMEnthused]

very nice change on the transmission.. Mckinney sells the same thing for the RB motors but im glad you are finally putting some power into the Nissan V8's, thats awesome. im going to subscribe to this thread. im also doing a big swap ( VG30 to S13)

im having to do a little less custom work than you are but still... custom work is custom work.

[Ezekial]

VG30 into S13 ... very cool!!

The latest with mine is I am still waiting on the powerglide and my chain guides are broken

I WANT IT GOING!!

[Mirage]

I am running a VH45 in my boat and am using a LinkPlus Engine Management system. It is easy to programme with a laptop and reasonably priced.It has been used extensively in Turbo Subaru rally cars.Look at their web site for more details. We also have a lot of Lexus motors using them http://www.link-electro.co.nz/

[Ezekial]

LINK ecu's are garbage

[Mirage]

Can you give us your recommended ECU with price and availability of programmes. please.

[Ezekial]

Can you give us your recommended ECU with price and availability of programmes. please.

My recommended ECU: MICROTECH

Supplied with base map to suit ANY engine!! Programmed to run with standard engine sensors. Unlike haltech, motec, autronic, etc

It works for these guys and it certainly works for me!

"The car has run it’s best ET of 6.96 and it’s best mph is 196mph. They are 3 times back to back national record holders for PRO RWD in Sport Compact for ANDRA"

$1000 for a 4 cylinder, around $1200 for a 6 or 8 cylinder engine. AUD!

If you have more money to spend ... MOTEC or AUTRONIC

[Ezekial]

block dipped

bores honed

waiting on:

new rings, new bearings and then balance the crank and then back together

[300zxwesp]

in regards to the over-heating, check into propane injection

does any one know of a tech site on the vh45 swap?

[Ezekial]

well after 6 months wait ... i finally have the powerglide

http://members.optusnet.com.au...glide/

As you can see ... It uses the standard VH45DE bell housing with an adapter plate to the powerglide.The red plate is a B&M trans shield so i dont lose my legs. I have to get a ballistic blanket so i dont lose my feet if the convertor lets go.You can see the transbrake solenoid on the back.The box is full manual valve body and warranted to 1000-1100 hp.The last pic is of the PWR trans cooler. around 300x280 or so

Now i just have to get under the car and scrub it with very VERY potent degreaser. Because as it is ... the gearbox is too nice to put in the car

As is the new rebuilt and blasted engine

[sijoko]

I like it alot. Everything looks very professional. Who did the work for you? I am assuming they are located in Australia.

Also, what converter are you going to use?

i believe its a TCE converter (obviously custom made to fit the glide and the VH45 flex plate)

Yes australia

Northmead Auto CentreWindsor RoadNorthmead (Western suburbs of Sydney)NSW Australia

They build alot of transmissions for some big v8's over here. Sub 9 second cars

[Blackbob]

So is this thing running yet ?

[Ezekial]

nope. definately isnt running yet. trying to source arp head studs and conrod bolts before the engine goes back together

[WDRacing]

I'm glad you posted up all the info and pics so far. I'm going to use all of them for my S14 VH swap. I'm going a fairly similar route, one big turbo, alcohol injection and SDS ECU. I'll be keeping the stock internals though, atleast until the grenade. The stock transmission will also be put through the ringer as well. Hopefully good fluid and a huge transmission cooler will help. With good timing management and some alcohol I should be able to run a pretty good amount of boost.

Keep us posted with any updates, my project won't be started for a few months yet. See if you can get yours running first...so I can follow your lead

[Mettler]

SDS ECU.

You should consider modding the factory ECU, I can arrange doing this for you. It's more powerful than an aftermarket job !

[hannibal]

Can you guys mod the VH41 ECU too?
