well you have the 2 highest whp NA cars in GA commenting in this thread.
Me and Chris aka All-Mota
So i would listen to us.
156whp is not bad, to get to 170 with just a compression increase, good luck.
youll have to get at least a point and tune to come close.
The HIGHEST WHP b16 i ever did was 99SIs motor. Stock block, stock head )port), M22X cams, valvetrain, JDM Dc header 4-1, 2.5in exhaust, AEBs intake manifold, Omni Valves.
178whp revving to 9500.
STOCK BLOCK.
His motor was rebuilt by us but back to factory specs.
a 15 year old block, i dont see it happening.
What cams are you running? If its still just the CTR intake, you need to invest in some ITR cams or a CTR Intake cam an tuning.
I still stand by the header choice, just because if you dont have one, you are losiong power.
But if you insist on going with the compression increase, flat faced valves an mill the head .010. Id run a GSR head to, youd get close to 11:1 with that setup.
then tune it
