I have a s15 turbo and going to tune it some time next week. My question is would sard 660cc (part number 63507) would be ok with no problems. Planning to boost 12-17 psi on a sr20, stock motor with upgrade Ras. I think 660 is more then enough but I can't let this great deal go away. I need to know what you guys think lmk. FYI I already have the walbro fuel pump, z32 maf and a nismo fpr.

If you're planning on staying with the S15 turbo, then thats more than enough. If you're planning on upping to 2871R or bigger later down the road, get 740s.

Also, what are you planning on using for the tune to run these injectors? You'd need a rom tune or even a standalone. SAFC or similar shitty bandaid tools wont work since 660s are over 50% over stock.

Just to give you an idea, I've seen 550cc injectors max out around 300whp. 660cc will probably get you to 350whp and itll be close to maxing out. Like already stated, better to have more room to play with. You dont want to be using injectors that are near their max limit. One of the reason injectors go static = maxing out injectors.
