Eric,
Thanks for your input.
250whp is certainly nothing to sneeze at, and that’s all stock? Tempting. I thought I’d seen “crank” numbers which didn’t seem terribly impressive.
I have forced induction. With a modest boost (a 10% pulley change) (and retuning) I figure I can hit or exceed 300 hp, (an arbitrary goal I set). I’d really like to do it though without blowing it up, to much fun to drive.
At 300hp would you still bother with new pistons? Would that be to lower the compression? Who sells pistons and other internals for these things?
Thanks, PK
