ive got a gt2ft that im putting an 18cvrx into. i will be using the gt side header. the port on the header is smaller than the port on the engine. should i try to dremel it open more, or wll it be ok as is?

thanks
josh

I would port match the header, it will help the gases flow better allowing more exhaust to exit while also allowing more fuel and air to enter, thus adding more power and efficiency.

is a dremel the best way to do this?

Its the easiest, you could probably sit there with a file and file away at it.
