I wonder if to help lose some height you could put a dry sump oil system in. that would let you drop the engine at least a couple inches and help with your center of gravity as well.
as far as torque... of course you would need to upgrade suspension a little but I think that if the carrera GT which weighs 3000 lbs and has about 100 more torque than even a well tuned LS1 can handle it. then the boxster should be able to also with some well invested upgrades.
widebody kit anyone?
