turbo ls1 in nsx

[2bar4g63]

hi, I'm new to this forum but by no means new to the import scene, I have a low ten second 2g talon but the unreliability of the 4g63 has forced me to look elsewhere for performance. So I jumped on the opertunity when I found a 91 nsx in a local salvage yard for $2500. From the windshield forward it is totaled, I have a friend that works well with chromoly so thats how im going to remedy that, i think. Now for the big question, the car didnt come with an engine, and due to the great cost of an nsx engine I was really hoping to put an ls1 i purchased a few moths ago in it, the main problem is not how to mount the engine but what transmission to use, an nsx tranny would be great, but again the cost, the only ones that I could think of are either an old porsche, fierro, or mr2 tranny with a custom bell housing of course. But I would really like to use the 6 speed that is already mated with my ls1. If anyone has any usefull information about anything I woul GREATLY appreciate it, and I know that an nsx engine and tranny is far better than an ls1 but I just cant afford that so please help a fellow enthusiest out. thanks a lot,
AL

Try looking into Quafe, Hewland (SP??), or Hollindger (SP??)

All 3 companies make longitudinal and transverse transmissions that are sequential or H-paterned. They are the ones that you see all the import tube frame big boy sponsered people are using.

I can guarantee you the Fiero and MR2 trannys will not handle the power, and have fun making them fit. The guys who are doing the V8's in the fieros are using porsche trannys most of the times.

On another note, Racer-X just posted a For Sale of a 3.0 block, and 3.2 heads, 3.0 intake manifold, and a tranny. Pickem all up and put them together, he was offering them at a VERY reasonable price.

Well, I don't have an answer to your question, but if you do a search, I believe engine swaps were discussed here before, and the conclusion was that the engine bay was not large enough to drop in a larger engine. You might want to do that search and then ask those people who know more about the subject.
Whatever does happen, please keep us posted if you can make it work or not.
Good luck

Are you aware how much of the NSX is aluminum, especially the frame and body? I don't envy you at all.........you've got quite a project ahead of you. Best of luck, though! Keep us posted on how it goes.

I was thinking the exact same thing

i was just going to get it cut off infront of the wind shield (front half it i guess) and custom make the frame and suspension parts from chromoly and put aftermarket body panels on

Yes, but I think the challenge here is how best to attach chrome-moly tubing to the rest of the aluminum substructure. Seems like a tough engineering problem. You'd have to use fasterners and bolted joints, I suppose. And then you'd have to be real careful about galvanic corrosion issues.

And even then you have the real huge challenge of mounting the Chev small block. If you're going to use the 6 speed, I assume you're going for a front engine longitudinal mounting. That seems to be real counterproductive to me. So much of the NSX's design is set up for the mid-engine placement.

I think you better do some serious design layouts before jumping into this project. Frankly, I think you'd be better off replacing the front-end with standard NSX components and spending your time figuring out how to best shoehorn the Chev into the rear - and mating it with a 6 speed NSX transaxle. That would be kind of cool to see and document.

Good luck.

I know, how about hose clamps?

But seriously, LS1 in the back of the NSX or the front? You do know that there is no drive shaft tunnel in the NSX, so that would require a rear placement. Transverse mounted V8? When you're done please give Tochigi a call and let them know how it's done.

Cars with transverse mounted V8's :

Most Cadillacs, Oldsmobile Aurora , Taurus SHO (the last version of it had a 3.4l V8), there are more.

Ferrari 348TB and TS , the T meant transversale.

Factory cars do have them, but still that would be one incredibly difficult engine swap. I'm surprised the have the car for only 2500, I could imagine you could piece off most of the parts for quite a bit more.

Actually, the T in the 348 and Mondial T meant transverse gearbox, not transverse engine.

Although, if memory serves me properly, the Lamborghini Miura had a transverse, mid-mounted V12..

where are you located 2bar? who has the car? I may be able to lend some advice and reccomendations

Not true. Most V8 Fieros use a stock transaxle. AFAIK, all Porsche trannys are longitudinal, which makes for a very nontrival engine swap. Dropping a V8 in with an adapter plate for the tranny bellhousing is relatively straighforward and there are kits available. See http://www.v8archie.com.

As far as strength, the 3-speed auto (ugh) with a shift kit is supposed to be nearly bulletproof. The manuals generally do fine as long as you don't abuse them.

I'm skeptical it would fit, but it would be interesting to see. Personally, I don't think the NSX would be quite the same without a high-revving engine screaming behind your head...
