EZ-E Posted December 7, 2004 Share Posted December 7, 2004 I was doing some research and found the the runners on the stock intake for a turbo Z are smaller then the intake ports on the head itself. Is this true? If so what or how can you resolve this? Would the intake runners take a porting to match the ports on the head throughout or would it even be worth it? Would it be better to go to a custom made intake? Quote Link to comment Share on other sites More sharing options...

Would the intake runners take a porting to match the ports on the head throughout or would it even be worth it? Yes, the runners are smaller than the intake ports. I cut my plenum in half and ported the runners all the way (from both sides) and matched them to the cyl head. Made a noticeble differences. Worth it? I had a friend to do the welding when I was done with the porting, so for me it was surely worth it (a couple hours work and a beer to my mate...).
