Guys, i wonder for stock engine, can we install bigger throttle body in ar ? Without any modification ????
Sato.....maybe give u some hints on that....
I will enlarge the SIRT stock TB to around 69mm .....the stock intake manifold will be polish and clear inside and make it like a wind-box to store more air.
It can increase more hp for your car
of coz u need to tune the A/F ratio by VAFC ...
