Setup:
B16 head, stock gsr cams, stock gsr valves/springs.
B18 sleeved block, CP 9.1 comp forged pistons, eagle forged rods.
Ramhorn turbo manifold, 3" dp into 4" exhaust
Precision SC6262SPM (just ordered...)
1000 cc injectors, stock fuel rail/lines, walbro 255 pump
stock ignition
Hondata s300

Goal is to hit 600whp

I am looking into upgrading cams to the s2 pro 1's. Would the s2 pro dual valve springs be the best bet for my set up which will see over 30psi of boost, or would I be better off going with some supertech springs for turbo applications (ST-SPR-H100DR)?

 

Yes This is a good question...
I'd like to know more about the recommended Valve Springs for Hi-Rev Forced B18C1.
