inlet/exhaust porting ??

[BluntyR5GTT]

as title really is it worth porting the inlet manifold and also de burring/porting the exhaust manifold?? i know on other cars this has had decent results

this has been asked alot, for you ££ is not really worth doing unless your after every last bit of power from your engine.. hit the search and you might find a few threads, or theres a marky mark thread in the projects area thats going into it all..:)

I would say its worth doing made a diffrence on my last gt. I could never pay someone to work on a gt head though. Deffo port match the inlet manifold and radius the part the carb bolts onto.

Not sure you'll get much, if anything, in the way of power but, the engine will be more responsive and help to reduce lag.

that sounds like its worth doing if it helps with spool up times :agree:
