Powerplant options and what not

[pecivil]

theres no way you will get upto 345 with tuning, headers and intake. That is fantasy land. Maybe 300.

Patrick,
I have just put in a 3.4 into my 2000 Box. It runs great, and with headers, intake and tuning should be around 315-320 at the flywheel. I will dyno soon to get the real RWHP numbers.

But for a 2002 boxster, your electronics will work with a 3.6, I would do that, because you get quite a bit more torque out of the 3.6. But the 3.4 rocks too.

Do the swap and dont look back. If you have a line on a motor now, and have the $$ to do it, why wait??? (said with the little devil on my shoulder)
