for anyone who cares:
1. The throttle body crossover tube from a 2.5 will work with the 3.2 intake and 3.4 throttle body.
2. fabspeed headers fit fine.
3. stock maf seems to be operating fine.
4. I used a 3.5" hump hose, stretch of 3.5" aluminum pipe, and the stock 987 cayman elbow. Not perfect, actually a bit pinched making the turn to the throttle body, but not bad.
High idle was a throttle blade that was slightly open. Re-routed throttle cable and now its fine.
Drove it a bit and it ran fine, but will get a dyno tune anyway.
