depends how big he is going on the head ports.
with the 272's your car wont like to idle when cold. It will also misfire when cold. They will also push your powerband back a little, but when that turbo spools it will kick nicely.
I would prob rec the 264 step 2's they are more streetable, has a better idle but still sounds nice, and will still spool that turbo acceptibly.
