I would say that with the 1.9 yes because I think it would create allot more heat to produce 15 pounds but I think that with the 2.3 you wouldn't have to spin it very fast at all to make 15 pounds on this motor with stock heads and cam. Im sure that if you were to do heads and cam and tried to make 15 pounds it would become a problem because you would have to spin the blower pretty hard to make that.
Back in the day my Buick Grand national couldnt take any more then about 21 pounds with the stock turbo and it would show knock on the scanmaster but with nothing more then a turbo swap it would make pass after pass on 22 to 23 pounds with zero knock.
Problem was the same as the zl1 in that the stock turbo had to be spun so fast to make that power that it was creating to much heat.
I do agree 100% in that detonation is the killer. I have seen stock Buicks live at 30 pounds and then I have seen some come apart at 17 pounds on pump gas and people getting greedy with the timing.
