i have a itr motor w/ itr tb and itr im... is there any major gain or improvement for getting the 2mm overbored itr tb w/ a portmatched itr im?

is it worth it? thanks

 

maybe 1 too 2 hp and better top end

 

you will see alot of throttle response with a bigger throttle body specially those 70mm ones and it help in the high end performance and of course portmatching and smoothing the runners in the intake manifold too will help gain with this upgrade will give you 5 @ wheels also extrudehoning the manifold will help alot i gained 7@ wheels with 70mm TB and extrudehone manifold

 

i was wondering the same thing b/c im using a ITR manifold port matched to a RPM 70mm throttle body

all motor setup

 

same here.

i have a skunk2 IM with a gsr TB and i was thinking of sending my TB to maxbore, wasn't too sure if its worth the 100 bux though.
