400 HP Boxster engine options???

jsceash, Great info! Thanks! That is exactly the kind of info I am looking for.

Sounds like a 04 or later S model would be a good starting point. Yes, I know that putting anything other than a Porsche engine in will require a lot of engineering on my part, but I am prepared and capable to do so. I have a lift, welder and metal working tools.

350hp would probably be plenty for me realistically. I want it to be a car I can drive on the street any day, and probably take to a track once in a while to scare the crap out of myself.

I have been researching the Subaru options more. Looks like you can easily get a motor to that performance for 6 to 10K. Also looked at other options. Audi RS 6 engines can be had for $3000 salvage. That might bolt right up. Anything I do will require figuring out making the engine ECU play with the Boxster. But I expect it will stand on it's own and control the engine while the Boxster ECU takes care of the chassis.

I don't really care about resale. Plan to do everything but machine work myself. Just something fun and fast!

I think I saw an 06 Cayman S roller on KC CL. He wanted too much $$$ for it ($9K), but you could probably get him to come down. A CS may be a better platform to start with. You might even be able to use the engine as your starting point using JS's formula.
