20s on a 240 q45 swapped car.

[trick240sx]

anyone know how hard it will be to get 20" to fit here are some picks. they are off of a 350 Z. They are 20X8 on the front and 20 by 10 on the rear. I got them for 500 rims and tires I also attached my track tank and some engine picks. Also is the 5 lug swap from a 300zx a direct bolt on or is it more work needed.

Heres 20's on my car,

Two years ago and two sets of wheels before the ones i have now.

Rears in this picture are 20x11 + 30 with 305/25zr20

[Florida240sx]

s13 or s14?

[hakosuka86]

Dang that looks quite nice.

[trick240sx]

s13 vert

[trick240sx]

appreciate it I have the wide body fenders on the back but I need to find some fenders that will let me run the20s on the front. I know what alot will say 20s are too big for a 240 but hey, vert (rare) Q45 swap with Nitrous and twin turbos ( rare) 20 on a 240rare and lastly I modified the dash so now I have a laptop disassembled and mounted the screen in the dash to flip up and the bodyof the laptop in the glove box. Mainly to program the nitrous on the spot but also to do programming on the chips in the car and to do real time monitoring.

I also plan on haveing the top redone and car repainted, also I found cream leather interior and I will carry that through out the car. When Im done this will be a true show qual car. Plus with the fenders done I can run a nice size slick for the track.

Dude, please edit your first post so the photos are not next to each other. Makes this thread an arse to read.

[David Steele]

No offense, but thats a real hack job and it can be very dangerous you going to clean up all that rust?

And is that fuel tank is just unsafe.

[craigztoyz]

The intake is my question.

did you just cut off the upper plenium end section, and just graft on another inlet? Just curious, seems like an odd way to do it, I assume you are going dual spool, and are trying to run the turbo piping seperate.Any one want to chime in on the flow characteristics of this idea?I don't want to trash this idea like I want to, Hoping to see what ya'll think. Personally, I see others run boost right into the stock intake, and they seem to have great low end. Just seems like blowing in from both sides, towards each other, would create a 'tornado' effect in the plenium, giving an uneven pressure across all the cylinders. The 20's ....... no comment

[craigztoyz]

I assume thats a vh41 by the alt duct taped up there?

[trick240sx]

To answer some questions.

1. That is half inch angle iron. The rust on it is surface rust. If you notice the other pictures you will notice the surface rust was removed,primed and painted with black gloss high temp paint.

2. You are not the first to say this is a hack job. If you look at the other posts this car started as a empty shell. It is now at this point. The front cross member, if you are familiar with the military hummvee will fold down when engine work is needed. It will pivot on a 1 inch bolt. It will further be tied into the shock tower for additional strength. From the shock tower another brace ( which I have see on this page will be mounted which runs behind the engine to the firewall on to the other side of the engine bay.This will tie everything together.

The fuel cell is as I said is for test purposes it is approved as its a boat gass tank. It has all of the approvals on it.

I understand it looks like a hack job if it remained this way but this is the first stage of fitting testing and tuning and then it will be disassembled and cleaned up.

The intake, yes it is 2 intakes combined. It also has 2 60mm TBs from a 240sx. The logic is the stock is 90mm, with 2 60mm I get a little additional airflow. The floor of the manifold mirrors each side to compensate for air flow. The manifold is also tapped on each side for nitrous jets for even flow. The main reason this was done is it is different,increased air flow,and the twin turbo setup. Each turbo is mounted outside of the enginebay and come in from the front. With the stock design it would take addition piping to run everything back to the left side of the engine bay.

The alternator is a test fit. It may be getto or whatever you want to call it. But it is a test fit for location. The other option is to cut the frame. Since I am using that area on each side for the exhaust that is not a option. Plus with the alternator there it still allows the hood to close. But to answer the question it is a VH45Apologies for the picks I was rushing to post picks and didnt realize they postedthat way.

[Carl H]

do you have any flow data to back up the twin throttle body mod?like other said before it seems like it would create alot of turbulance.

[trick240sx]

also with the 20s I was asking so i have an idea of difficulty to fit. I got all 4 with tires with 90% of the tread left, for a real good price. If it will be too difficult I will trade or sell for 18s or 19s with a nice lip and nice look.

[Mettler]

You're going well so far m8, don't let naysayers put you off! Finish it, do a nice job, and prove them all wrong!

I did want to call into question your comment about getting additional airflow from using 2x 60mm throttle bodies... with some cross sectional area calculations, the following becomes evident:

Dia. 60 circle: Area = 2827.43 square millimeters (x2 = 5654.86)

Dia. 90 circle: Area = 6361.73 square millimeters

So the standard dia. 90mm tb still has greater cross sectional area than your twin 60mm throttles.

In saying that however, reduction in area doesn't necessarily mean a reduction in flow, as it can actually serve to increase airspeed. I've been advised you can increase the port velocity on a VH by slightly filling in the intake ports and reshaping the port floor, creating an overall increase in port velocity at all RPM.

Of course, this doesn't relate to the throttlebody, but it just highlights that bigger doesn't necessarily mean better in some applications.

You've got a long way to go yet man, keep up the good work.

[Raxephon]

.... it seems like it would create alot of turbulance.

Not if you put a divider in the plenum seperating the left engine bank from the right.(Only problem with that is if you are trying to use the factory iacv)

I was considering this mod when Wes mentioned it awhile back but I'm undecided as to whether I prefer the "spider" or the valve covers being visible.

[DeXteR]

Keep up the good work!

I was a nay-sayer at first as well (partly out of jealousy, partly due to it just looking plain bad), but after talking to him a few times, I'm confident this will turn out well. Let's not jump to conclusions, be patient, and let's see how this turns out.

Now, to comment on the intake manifold. I have some fluid mechanics education from engineering. I'm going to agree with Mettler that bigger is not always better. The basic equation for flow (flow = velocity x area) dictates that if you're pushing the same volume (air from your turbo), you'll get higher velocity with a smaller opening as opposed to a larger opening. Of course, there are many other factors to take into consideration, but generally, you get the idea.

Will this create more turbulence in the intake manifold? Probably. Will it have a negative effect? That's something for speculation (or someone with more education than myself on the matter). If you're worried about it, run the divider like you had for plan B (he all ready thought of this per our previous conversations). However, to compensate for differences in flow (surges, uneven combustion for some reason, etc.), you should consider doing something to equalize the pressures on both sides. Perhaps drill some holes on the outside of the divider (not in the middle as this will defeat the purpose. How many holes and how big? I don't know. Again, that's something for someone with more education/experience than myself.

This may not even be an issue considering the fact that the intake manifold appears to have a very symmetric design. Would it in fact create any more turbulence than if you were just running one large inlet with forced induction? Just some food for thought.

On a side note, old-school V8 guys do all kinds of tricks to increase intake velocity just like Mettler was saying - filling in the intake ports and reshaping the port floor. Take a look at some of the things they do in the Engine Masters Challenge - google that and take a look at some of the intake modifications on winning engines in the past.

Now, to get back on topic... I think 20's are kind of big. I have no experience though. If you can make them fit, go for it! It's going to be an insane car when it's done. You might as well go the extra mile with some crazy wheels.

[trick240sx]

Thanks Mettler and Dex. I thought it was a **** on me day or something. I admit I am working with basic knowledge as far as flow but I did account for turbulance by mirroring the floor of the manifold. Before it was a constant angle on the floor from left to right. Now at the central point of the manifold they both angle to an apex. As far as flow data I have another stock intake and mine. If anyone knows of a place in VA or Maryland I would gladly get it checked and post. And yes if I do come into the problem with turbulance I planned on placing a baffle.

But like I said I appreciate the support. I look to have it test ran by the end of the month and then I can trim the excess metal, complete the body work and so on.

Mainly the manifold was made like that to ease the twin turbo install with my knowledge and tools. 300 for the manifold work. 1300 for someone to do piping alone.

[craigztoyz]

FYI-- I wasnt hating on the engine, alt, just really curious, and have some doubts on the airflow, but cant wait to see it up and runnig to see how it comes together. The alt, I looked at that too, and am thinking of using one from a rx7 due to its size, it will fit in the top location better.How are you looking ot mount it there? I was looking, and with the water lines, it could be fun.I think the 20's are for looks right? when you take it out to get all up on it, you'd run diffferent tires right? as those will be burned off fast, and with a 25 tire height, one bump too hard, n oh .....

[T45]

No offense, but thats a real hack job and it can be very dangerous you going to clean up all that rust?

And is that fuel tank is just unsafe.

This is the worst post in the history of NICO. First you try and excuse your insult by saying no offense and then call his build a hack job. Give him a break. HE IS BUILDING A TWIN TURBO VH BESIDE HIS ****ING HOUSE UNDER A ****ING CANOPY!!! There is no right or wrong way to do it. It's HIS way, and he's doing it with about 1/2 of the resources most professional shops have access to.

If you want to see an unsafe temp. fuel tank take a look at Mettlers setup in the vid of the halfcut. He ran the fuel from a bucket. I don't remember hearing any negative comments about that. And as for the surface rust comment you have just shown your I.Q. score to everyone here.

Something to keep in mind when looking at someone elses build is that you don't know what he has already conceived as the final outcome for his build. He's thinking way ahead in the project, instead of looking at a picture and seeing where he's at.

Mad props to you trick240 for tackling a project most guys can only dream about and for pushing the envelope on the VH. There are only a handfew of TT VH's out there but you'll be the only 450SXTT convertible!

[DeXteR]

. . . you'll be the only 450SXTT convertible!

For a little while anyway - until I get around to it as well.

[AZhitman]

Holy crap.

That's bad-freakin'-arse, regardless of what the naysayers will offer.

Good luck on the build, altho I'd love to see that thing on some monster-wide 18's.

Loving the ingenuity - Keep up the work man!

[trick240sx]

Thanks for the support. Yes the 20s are for show. daily riding and car shows. As I stated before If someone was willing to trade for a good set of wide 18s im open to it. But the mods I would have to do with the 20s will benefit with any other size tire including slicks.

No offense taken on the ALT but when you say the duct tape alt set up it kinda hard not to. But Im exploring the use of the hole on the block on the left bank where the PCV is bolted for one hole. I drilled it all the way throught and it lines up. Then for tension on the belt I can run a bolt into the top of my existing waterpump adapter block. This will push the alt up and tighten it. Im test fittin the Honda Civic Alt because of size and Bocshemakes a 180 200 and 210 Amp Alt for between 500 and 750. But it will fit.

The build thread will be better once I am done. I will be tearing it all down taking picks and putting it back together. i also plan on documenting the wireing of what is required so it wont be an issue anymore.

But Thanks for the support from all.

Dude that video on youtube of those guys revving that VH41DE halfcut, that's not mine, those are some other dudes from the south island I think (hence the video being posted from a completely different youtube account to mine.) By the time they'd posted up that video, I'd already had my transplant finished for like 5 months!

In saying that however, I also ran my VH temporarily with petrol in a bucket as the fuel source Except my engine wasn't even in the halfcut, no, I had it sitting on its sump on top of a subwoofer box, with axle stands supporting it under the factory exhaust manifolds... long fuel line to the fuel pump, which was submerged in a bucket of petrol outside the door.

Yep, good times... but you won't find those on youtube!

[Carl H]

why do you need 2 oil filters?pressure drop is going to be killer thru that not to mention you're also trying to feed two turbos.

Yes there are wrong ways to do things and it wasn't an insult retard.

That frame has some bad rust on there where the wheel tower picture was. I'm not talking about some untreated surface metal.

Wow a house, canopy and ''twin turbo'' flashy words dude calm don't ruin the thread. He's responded and it's said and done not your car I'm commenting on.

A tank that wouldn't pass any inspection what so ever at a track here. I didn't see any info about '' tank for test purposes'' anywhere in this topic except in his response to my post.

bla bla bla ''keep in mind this is a forum'' and if you post up pics they will be commented on, so if you don't like whats said then you shouldn't post pictures up.

Original post was edited the descriptions were vague for the pictures so you = nonsense.

[Mettler]

Cmon guys try and keep it friendly... of all people I know what it's like to lose my cool, but it's best if you remain analytical and keep the insults out of it.

[T45]

David, If all of those things were intended to be said that way then you should have said so instead of just posting up a quick "your build is a hack, your work sucks and you're going to wreck and die" post.

This is a forum and we have to take everyones posts for what they are. We can't distinguish jokes or intentions through such vague posts.

It's not my fault he didn't post pictures with enough info my line were put in the form of a question and he explained thats enough for me.

[trick240sx]

Everyone thats supportive I appreciate it. Everyone that has objective views I respect your opinion and its noted. I dont want a thread with alot of back and forth about simple things.

To touch on a few things though.

The so called rust you are speaking of is a combination of two thing. Surface rust and red mud from being pulled on the trailer. As stated before I started with a shell. Once I can take it to a pressure washer it will be gone.

The dual filters I am talking about come from Amsoil. Look it up on their page. Once filter manages the main flow and the other gets ride of smaller particles. By thier page it should not be pressure drop. Also we are all talking about an engine thats 18 yrs old not a fresh out the box engine.

The fuel cell as stated is for track purposes. But next time ask more questions before commenting. The local track has a test and tune day on sundays. I will pass the technical inspections for the track. It has the same thickness of any other fuel cell, it has been pressure check and so on. The only change was the hole being cut, and the factory Q45 fuel pump mounted to it. http://www.amsoil.com/StoreFront/bf.aspxAs always ALL OF THIS IS TEMPORARY THIS CAR IS FOR MILD DRAG, ITS MORE FOR CAR SHOWS.

But as alway thanks for the support it is appreciated.

[T45]

Sorry to derail your thread Derrick. What track are you talking about? When you get it finished I'll come out and swap some paint with you.
