I've had a 3037s on a standard (bottom end) rb25 with cams, greddy plenum etc etc which ran with no issues for quite some time at 380hp at 1bar. However once I started pushing the boundries of 1.2bar, the bottom end did let go and it punched a rod out the bottom of the block. My suggestion, and it comes from experience, is don't push too hard on your stock bottom end or you will see dissaster. Also cams will easily aid you in your quest for earlier power. Like adrian said if you want earlier boost get a smaller ex housing, however it seems as though you arleady have the turbo and some other gear. All I can say is good luck, take it easy and save up for supporting mods because once you get 300hp you'll want more.
