Successful 1ZZ Throttle Body Swap

MugenRep: Does the 1.3 intake manifold have any room for light porting? Porting a stock manifold to match the 1zz tb for nearly free is a better deal then tb port. My apologies for sidetracking your question.

There may be room for porting. It's a two-piece intake manifold. The TB attachment and primary runners are composite plastic and the secondary part of the intake manifold is cast aluminum. I'd assume the primary portion of the intake manifold could easily be ported out as it has an almost tapered rectangular-like shape with the 4 runners at the base and the TB mounted at the top point. There should be plenty of room in the inlet, dome area, and runners to port. Not sure how composite would port, but it could be worth a try to do so.
