Moving to S2000 talk

 

The sister company that work for has ITB kits for the S2000, the company is Redline Weber they do the Weber carbs, EFI fuel injecton system and they have had the ITB kits for the 00-05 S2000.

I think retail on these puppies are around 2200 with a street selling price of about 1900-2000. I will ask them in the morning on the prices and take pictures of the actual ITB setup for the S2000.

 

i found a link to the ITB's that our sister company makes

I'm just reiterating what folks've said...

For performance it's probably tough to justify compared to supercharging... but the sound is unique. It sure makes the engine bay look cool.

 

Whoa, a lot of good information shared here. C me go, in my modest "personal" experience, go with the SC. YOU will be very happy. SC's are your friend...

Seriously, consider all your options, try to speak with and ride in with someone who owns them and has gone through the process of running them regularly, then take a ride in a SC car...If you go to the South Florida Supermeet, there will be "lots" of FI, but no ITBs...(that I can think of).

In regards to the boring the throttle body and manifold and losing horsepower it is quite common in small motors. With small displacement motor, having a larger diameter openings and runners going to the head allowing it to "breathe better" won't neccesarily give you more power. With small motors in particular flow is as, if not more, important than volume. Unless you intend to port and polish the head, and get a valve job I wouldn't expect gains from boring out the manifold. With forced induction this would change.

In terms of value for money I would purchase the supercharger before ITBs.

 

Those look alot like TWM's....

 

The Reline piece has a much better linkage for the F20C then the TWM setup., atleast in the picture.

 

XViper, you've made the comment that what's true for other engines might not be true for the S2000 and for most car's I agree. The Integra R motor though is basically the father of the S2000 motor and what holds true for one is almost certainly true of the other.

The F20C is the same generation as the B18C5 with the same engine management and nearly the same RPM range (B18C5 fuel cuts at 8600 RPM). The B18C5 is closer to the F20C than any other engine Honda's made. The K2X's engines are the next generation with different Vtec even.

I'm pretty sure you could look at the results of ITB's on Integra R motors and have a damn good idea how it would work on the S2000. I'm not convinced that with a stock S2000 motor, it would buy you much. Honda's probably got about as much airflow through the engine as you're going to get. A bored and stroked F20 though, it's probably the only way to feed enough air to the engine.

You'll never pass emissions with ITB's either.

 

id be getting some new rims first. those things are ugly. sorry. but as to the itb's, ive thought about going that route just to do something different, not for the h/p.
