The SR20 throttle-body trick won't work on the 2nd generation GA16DE, which you have. The reason is the '95-'99 GA16DE incorporates the TPS and IACV in the throttle-body itself, where the '91-'94 GA16DE (1st generation) has the IACV on the opposite end of the intake manifold. The only option for us in terms of a larger throttle-body is through JGY or go custom.
I see... Damn it all. So is there a manufacture that has a good sized Aftermarket one that works, can't i use a Throttle-body off a later SR20? I thought the GA16 was mapped almost identical to the SR20 in this regard.
My Question now actually is, can i retrofit a intake manifold from a B13's GA16, or is it a lost caws and i should just move on to my next steps, that being Headers, 200SX cat, and custom 2" tubes to a good muffler.
