I am throwing in a t67 with stock head and block with arp head studs. I already have a skunk2 mani that worked great all motor. My homie has a vic x on his stock gsr and got some good numbers (360whp,250tq). We are both reving to 84k, but i heard vic x is only good for 7-10rpm and smaller intake manis are better like the s2 for the 5-85k range. or would it be worth getting my s2 ported?
thanks!
peace

 

well its not going to be ideal either way since you have a stock head and stock block with a fairly large/laggy turbo

if you want to spend money get valvetrain so you dont fall out of boost in between shifts

 

I just ported my s2 intake for my gsr head. My car will be done next week so I will let you know how it performs. I think it should flow great as there is no restrictions what so ever now that I re worked it.

 

k thanks!
