As the title states I'm wondering if I can install small twin turbos onto stock internals without damaging anything?
I'm not looking for more top speed and I don't want high rpm turbo lag.
I'm looking to add lower rpm/speed power&acceleration.
If this is possible, what turbo kit(s) do you recommend?
How much boost should I run?
Is this a bad idea?
Thank you.

 

Supercharge?

 

I don't really want to super charge because it's heavy and expensive and reduces fuel efficiency.

 

I may do this as a last resort if I have no other options.

 

The two worst answers I can think of.

To answer your question, yes you can. The block is stout and can handle good HP with a good tune and provide reliability if you don't cut corners.

All the kits I can think of are single turbo. Check out the FI forum: https://www.s2ki.com/s2000/forum/142...ced-induction/

 

It is possible, but it will be a custom ordeal. There are no "kits" available for a twin turbo application

What fuel do you plan to use? On pump 93 the norm is 9-14psi depending on wastegate spring sizes available and your boost solenoid. 450whp is about the safe limit. The stock internals can handle 600whp on race gas or ethanol

Well it's an idea, and it's been done before.


Adding two turbos, and manifold to support the two, downpipes, wastegates, dumptubes, will far out weigh any supercharger kit.

 

So u don't want the weight of a supercharger because it's heavy? 2 turbos will probably be heavier. If your worried about your mpg, I don't think this hobby is right for you. The only reason why that s2000 went twin turbo was because the customer wanted something different. That power could of been made with a gt30, and that dyno graph didn't really look like it had massive low end like you wanted.

Do your research. Look up a greddy turbo kit and look at the dyno graphs and see if that's what you looking for. The amount of money you put in for a twin turbo, I'm sure u can go the v8 route.

 

Stroker kit; small single turbo

 

Hmm it seems like I'll have to do some more research before I commit to either of these options. Does anyone know if my fuel efficiency would increase with a single or twin turbo setup?

 

Don't count on it. In almost every scenario it will decrease.
