stcok gsr head, built bottom end , sleeved , 84mm 9.5-9.8 comp. sc61 turbo...... how many pounds would be safe on a stock gsr head? (dont want to spend the money right now to get valves springs retainers).
also , either will be running hondata or aem ems.

also would 91 octane work or too mcuh problems?
i can get 93 if i have to..... only couple places have it.

w/ that kind of compression, Boost pressure will only truely be realized on the dyno. If your tuner is competent, then they will keep an eye on Air/fuel ratios, compression, and other attributes and you'll learn how far you can go from there. Especially w/ AEM or Hondata..

There's no true prediction. Go find out and see, honestly.
