best trans for a hi-po bug

[thelazerviking]

what are some good trans setups for a bug that will be putting out 250+ HP? I'd prefer a 5 speed but i don't know what porsche trans' will handle it and go in without too much hassle and i don't really want to get a 5 speed kit. however, i don't really mind going 4 speed, i just need somethign that will handle the power i want to put out. i'd like to keep the cost under 1200 dollars, i don't mind riding on a used transmission, just so long as it holds up.

thanks a ton
