My guess is the 3.2 heads won't flow enough to get it.....so intake, exhaust and significant head work are required. Porting, camshafts, valves / springs, cam timing. This restriction was of course put in place by design. I believe one can approach 300 with bolt ons but I have not heard of any being able to break through
Woody posted some surprisingly good dyno results from bolt ons and ECU tunning. I would link it if I could find it.
If we get into the heads and start doing it, how is the 3.2's propensity for head cracking mitigated? One could asks this for a total engine build as well.
I feel your frustration ......I remember track days where I just couldn't shake old 993 on my tail...
