im having to open up my intake port about 3 3.5 cm due to a crack above the intake port. thus I need to open up the exhaust port also (going to make a bridgeport instead of streetport)..after talking to a couple people and doing some research would a gt42r be too small?
thanks

Just so you know, ErnieT's old CYM car that trapped near 150mph in the 1/4 with a semi pport was WITH STOCK EXHAUST PORTS. Take that for what it is worth.

With a bigger turbo and stock ports it would create lag upwards to about 3500rpm... I want boost everywhere
