helloo eveyone , i need to know what is the best setup for road racing ,whether the ITB or TB will perform better. For ITB , three choices TWM ,Toda and Jenvey,not sure on which brand to buy.I am open to any suggestion from you guys that have experience with any of them.My engine specs are as follows :

B18 type r with EG chassis
Wiseco 81.5mm +5 cc piston (c/r is about 13:1 now)
Peak performace H beam rod
JUN type 4 cam and JUN valvetrain
PNP type R head and manifold with standard bore TB
DC titanium race header
RC 370cc injector
MOTEC M4pro
Custom straight cut close ratio and final gear
JS racing intake

 

Where do u plan to road race a honda with a setup like that?

Or do u mean track days/lapping/hpde?

I'd stick with a manifold and use the $ to get out to driving events and learn.

 

cant beat throttle response with ITB's...not knocking tb/plenum set ups..so cool your jets
if the funds are plenty, go itb's...

 

I have a fake J's racing intake for sale that was designed for road racing. Throttle response is awesome, and it's made of ABS plastic to keep intake temps down.

I tried that on track. Fake J's, Carbon short ram, and iceman.

To be honest, I couldnt tell a damn bit of difference between the 3 - same response, same top speed down the front straight, etc.

 

I usually end up getting ITB's anyway, even for my daily drivers. The response is beond belief and the potential for midrange power is nice to have.

ITB's all the way. response is great i run them on the street all the time. just switch motec to read alphanumeric and it's all good. Pm me for any questions on itb's. I can size you up for your set up and answer any tech q's, we just deal TWM but I'll help out with what ever you get. ITB's TWM

I think its all kind of a moot point since for real "road racing" (not street jackassery) there are very, very few places you can run a built engine with ITB's.

 

In my country the track is high speed, i ran a 4,2 final with a 1:1 fifth speed.So which one to buy ? I like TWM and Toda ,also what are the effects of putting the plenum on ITB .THX

 

what is the best for road racing ?TWM 50mm or Jenvey 48mm ?
