I have a JDM GSR motor with all the regular bolt ons, and now im trying to determine what cams im going to get. I know that CTR cams are good with stock valve train while Skunk 2 will require a vavletrain upgrade which is not a big to me. I also know that stage 2s also prefer higher compression. Now here is my question, on my stock block and compression as it is now, will the Stage 2s provide more power all around than the CTRs will?. The reason why i ask is because even if they do not provide their full power on my stock compression but do provide more power than the CTRs would then i would go with them because at the moment i can get CTRs and Stage 2s for the same. I know i do plan on bumping the compression later but i just want to make sure there will be a notice able difference now

 

To answer your question the crt cam will provide more all-around power with the mods you have but with some head work and up-grading the v-train asy the sk2 cams will kick ***.. But it all depends on how far you want to go with your motor set-up

 

To minimize as much problems as possible and to keep the care more reliable, i think im just going to go with Stage ones with the springs and retainers .
