I have an allmotor LS in my Hatch and was wondering how i could squeeze some extra horses out. I have several plans for later this year to get me past the 170 WHP mark that Im stuck at now, and one of the ways is a set of custom ITB's. Now this hasn't been done much on LS/B20's for the exception of one person with an allmotor B20 that laid down 198 whp.
I am just curious if I should go along with it and what are the advantages/disadvantages of it. Like:
1. How much will my low end suffer with ITB's?
2. Is there any other Throttle bodies that I can use besides GSXR and CBR ITB's(these are becoming harder to find and more expensive)?
3. Is there anyone else with a similiar set up as mine running ITB's(click on the link in my sig)?
Most of the cars I have seen this done to is Vtec cars, and yes I have searched, but have not found any before and after dyno comparisons. Any suggestion and comments are helpful!
a buddie of mine up here in the central valley just purchased a set of 1000cbr itb's. your low end shouldn't suffer at all i know that the throttle response is way better and the 1000cbr throttle body use a obd2 injector plug and the throttle position sensor is the same as a honda car all you would ned is a old ls intake manifold and have everything machined off minus tthe flange then have a good welder weld up some 1 1/2 inch aluminum pipe to the flange then get some 1 1/2 rubber hose and 8 hose clamps and you are set i think we invested aproxx..... $275 in his whole setup and gained 18whp not a bad gain for 275 bucks huh and he pick up his power from 3800 to 8600 on a stock b16
