Hey guys,

sorry if its a real noob question or has been addressed before but can it be done, will it work and will there be power gains or any other benefits?

would be best to port match your intake manifold if you do/can,

will only gain throttle response.

personely i dont think changing the TB alone would make any difference at all... your engine will only require a bigger thottle opening when its sucking harder than it was designed stock...ie. after bigger cams, more RPM ect.......

the GSI was never ment to REV like a ITR so there was no need for a big TB....

A bigger TB would only work in conjunction with other mods...
