Which gives more power?
I ask because my brother has an 87 GTA and I have an 88 GTA. His came with a coplete SLP exhaust ,K&N, and siameised runners, but nothing else. My car has ported L98 heads, ported upper and lower intake,(all extensively ported),K&N, SLP cold air kit,Modded MAF,AFPR set to 47psi, no converter,3' pipe w/Dynomax race magnum, Transgo shift kit. Also his has a shift kit.
But my question is do our mods cancel out eachother or what? He keeps running his mouth and I haven't had time to race him.
What do ya'll think?Does heads and induction ported make the same power that siameised runners and headers make? His plennum isn't even ported for gods sake!

Your mods destroy his. His stuff is minor compared to yours.

I would say your ported heads, intake and everything else are much better then his mods. I'd put some money on that race if I were you.
