I dont know much about throttle bodies and such. I saw this guy on here posted a vid of his S2k w a throttle body and i loved the way it sounded, but i thought the performance w a turbo would be so much better. I was just wondering, what exactly is a TB and what does it do?? Can you put on a turbo with it? and what brand of turbo kits do you recommend?? Please include prices for both items if you can. THANK YOU!!

 

Pretty much all moren cars have a throttle body. It's a part of the air intake where you have a butterfly valve controlled by the throttle pedal.

What you are referring to is an enlarged throttle body. You take a stock throttle body and bore it out then install a larger butterfly. Makes bugger all difference NA but supposedly makes quite a bit of difference for FI.

You can get an exchange throttle body for about $150 I think.




The turbo kits currently in production and popular here are the Rev Hard and Ultimate Racing systems. Expect to spend $5-6K.

 

I think he's talking about topfeul's independent throttle bodies (one throttle body for each cylunder). I suppose you could plumb it to work with forced induction (turbo/supercharger), but any power you gained from having them would be lost...bottom line, independent throttle bodies are for N/A (naturally aspirated) motors only, you'd be much better served with a larger-than-stock single throttle body for forced induction on the s2k.

I would disagree with Bahula03.

Take Hayward or Jenvey ITB's linked to a forced induction supply would give maximum performance.

The main advantage would be that you are not restricted by the orifice limitations you get with a single tb. I know that Jenvey's ITB's have been used in this application before (not on an S2000).

However please note that a chamber would be needed to encase the ITB's - & it wouldn't be cheap or easy to set up.

 

Oh, I see!

ITBs are great with FI. You need to encase the intake stacks in a plenum chamber but the increase in throttle response is awesome.

 

by the way, you could have the TB increased to 70mm for less than $50 USD in Taiwan..

 

you can do it for 75 bucks here in NYC
