my setup right now is 98 spec JDM ITR motor, stock internally, oem itr intake w/ spoon filter, hytech replica race header and 3" exhaust

i ran across a good deal on twm 50mm itb's, and i was wondering if i slapped these on and tuned with crome pro, what should i expect? i'm not looking for peak power gains, but more mid-range and throttle response, which is what ITB's is all about (from what i can understand)

would the 50mm itb's be too big for a pretty much stock itr motor? it rarely gets driven on the streets

 

i love mine, make sure your tuning with someone that can tune tps/map and ur able to fool with the tip in. My twm's , i love them, alot of people have mix reviews, but coming from someone who daily drives his car, and has had these same itbs for over 3 months w/o any problem says alot. I actually recommend taking them all apart and caliberating them urself tho, i actually ended up doing that with mine because i couldn't get the plates to open 100%, they do now tho because i took the itbs off and redid them. I also suggest into looking into bigger cams to max the output of the twm's, i use s2s2's and have great results, street wise, i feel the power come quick, overall even with bigger injectors i'm taking in more then 40% of fuel everywhere, so the increase is felt. The car just keeps reving and the power feel on the butt dyno is great. My car idles happily at 900 rpms
