im purchasing this kit "RevHard Stage II" for my 98 integra gs-r and plan on running on stock internals... i herd ppl say revhard boosting only 7 to 8 psi stock internals = fine! but sum say its still a turbo and needs minor head work and needs to be sleeved and such... i need opinions on what honda-tech boosting guys think... also if only boosting 7 to 8 psi is it better to run a 3 inch exhaust or a 2.5? if 2.5, what boost lvl should someone change to a 3 inch? thanks!

 

I have that same kit. I run 7-8lbs also. I gonna be running 10lsb in a couples of weeks. You will be more than fine at 7-8lbs if you tune it.
