set up will be a FULLY built gsr 9.8:1cr w/ stock stroke and crower turbo cams. Power goal is 450-550whp. Which should I get? Any recommendations and why? I don't know much about tubros and sizes. I will be using it for street/strip. Are there any others that I should consider instead that will have less lag and still keep me in my power range efficiently?

 

Skip the crower turbo cams, and get the 35R.
