Hey i got a question, has anyone ever peiced together there own twin turbo kit. I know alot of people with nsx's have deep pockets but for us few that are extremely young that own one, that probably shouldent, :biggrin:

Im very knowledgable when it comes to boosting and i was looking at the turbokits.com tt kit for the nsx, and its looks very basic. I was thinking about starting a project the only thing i would have trouble with is the computer they use and there tuning tools.
 
go for it....lots of people are doing the same thing but they dont post here too often...they dont have the thick skin for it :)

ya dont need to go twin though..........
 
Yea but a manifold for a single would be tricky but very capable, I am usually one for swapping out twin turbo for a larger single turbo but were as the single's are usually for people runnin insane amounts of boost, ill stick with the twin turbo, i also think it will spool faster and you can use 2 cheaper turbos that cost less than your average large ball bearing one.

Yea i got thick skin :tongue:
 
My 2cents based on an assumption that you are not doing an engine build for FI:

Provided you run low boost (<9psi), include adequate charge cooling, run a properly sized fuel system and proper tuning via a standalone... you should be able to produce something that is strong and reliable.

Good luck
 
Personally, I think if you can make a low pressure turbo that can make about 350rwhp on a stock motor (3.0) that is reliable.... You would do very well. The added TQ from the turbo would make the car a lot more fun to drive. Most people don't need 500HP to have fun. Pricepoint would need to be 6K.
 
HAHAHA. Like clockwork. Every few months someone posts the same thing. :rolleyes:
 
haha actually i think alot of the turbo nsx's we dont hear about are DIY,
besides, my plan is to strap rocket jets to my car and hit mach 4

Not sure if you are serious or not, but yes. Even 330rwhp. It is a decent bump over a stock 224, but the TQ would be MUCH stronger and with full boost at 3K rpm, in-turn make the car more fun to drive.

Must be around the 6K mark in price and be a single and I think it would sell quite well.


It's in the works! And OBDII even. Stay tuned.
 
Personally i don't see the point in a turbo, let alone twin turbo unless you're boring as hell and just do 1/4 miling. I personally wouldn't want on/off boost around a track, its the complete antithesis of the NSX. I don't see much talk about ITBs round here, surely that is the best upgrade engine wise? I know they're pricey but the sound is better than anything else...

Rob-

I am curious which turbo NSX setups you have driven or rode in to leave the impression that there is no point unless you're drag racing and that boost is on/off at the track?

The NSX is a great track car already with minimal work, but I couldn’t disagree more with the rest of what you said. But then, I've owned turbo and SC NSXs as well as other cars and have never run an official 1/4 in them, so my perspective has been influenced by reality. ;) Seriously though, turbos aren't for everyone so do what works for you.

Edit: Left out the "never".

That is definetely the old school of thought. With compression and turbo sizing you would be surprised as to what little, to no lag there can be. ITBs can be quite the opposite of what you are thinking, especially for street use.
 
Well im thinkin two extremely small turbos will spool extremely fast, almost no lag at all, Im really looking into using, 2 14b turbos off of a 1st gen dsm, they have brought people into the 11's and can run around 20psi, but i wanna do a 5-7 psi setup to bring it to just over 300rwhp. the power would be instant, as quick as a supercharger but less strain on your motor as the sc has to take power to make power.

You can nearly get over 300rwhp with i/h/e on 97s. Did you mean 400? I don't think ANYONE would buy it for 300rwhp. I think 350 is the magical number and of course the TQ.
 
Honestly if someone can show me a dyno sheet were they did I/H/E and broke 300whp i will give up my dreams and buy there exact setup, lol

But anyways, look im not making this kit to patent it and sell it and profit, im making it for my own application and needs, after i complete it i will post results after that if anyone is interested i may be able to make more, but i know the kit isnt gonna cost 7-8 grand thats for sure....

i think a 14b turbo is a good choice. my dsm hits boost at about 3 thousand RPMs

I would recommended small 16G.
 
I would recommend not wasting your time if you are only going to make 300rwhp. Seriously. I don't want to be rude, but NOBODY will buy that.
