My car is due to be tuned in the next several weeks. The block was bored out to a 2.0L. Specifically, the turbo kit on the car is a Full-Race Stage 3 with a T3/T67 with a .63 A/R. Currently the injectors in the car are RC 650cc and all the relative fuel supplying parts have been upgraded.

I was told that since the builders and I are shooting for 600+whp on C16 and around 450whp for the street that I will need larger injectors. I just plugged some numbers into the calculator featured on the RC engineering website ( http://www.rceng.com/technical.htm )with my expected hp gains and it gave me a calculation of 635cc.

The people building my car are telling me to make those gains I will need 1000cc injectors and the relative parts to make them work.

My question goes out to those of you with knowledge and factual data in this area. I'm simply curious if the 650's will be fine, or it's time to start gathering the parts required to make tune happen and the hp numbers mentioned above a reality?

Thanks to all in advance!

i'm think with enough fuel pressure you might be able to supply enough fuel for 600whp, but why not play it safe and just get the 1000cc? i'd hate for your to spend the money for dyno tuning only to have to re-tune the car because you didnt have big enough injectors the first time.
