hey guys. do you think there would be a noticeable difference in throttle response and power if i combined itb's with a cai on a 7afe engine. is project worth it. which other modification would you think would be needed other than throttle cable and adapter............

Just run ITB's with filtersocks, forget the cai... Yeah it might change the powercurve a bit. I mean you have a direct line to the valve with ITB's and you can change the harmonic length to alter the powerband.

ok if i forget the cai. and use open velocity stacks....or filter socks i would get a little bit of more pep????


also with open velocity stacks what kind of sound can i expect to resonate from the engine bay..........? a high pitch whistle type or a low growl.

ok... about the TPS.... if you were to run 20V itb's, they have a toyota 4 wire tps on them already.

however, toyota ecu's run fine w/o a tps signal..... strangely enough, they run better w/o one than with a tps giving a bad signal

Toyotaspeed, yeah because a bad signal confuses the ECU more than no signal at all. Just like when the o2 sensor in the mercedes crapped out, I just cut it off.

would the itbs actually fit on a F head? never knew it would....
Well they dont fit the 16V G-head either without an adaptor plate as far as I remember.
