I think that there just isn't a good enough pay-off for anyone looking to develop an actual kit. Most of the market to replace failed engines in an old Boxster is probably more of a budget buyer. Making it all well takes skill, time, and money.
Round up 30-50 buyers (investors) with $10K each and turn John (
BoxsterLs376) loose with it. Check out what he said near the end of this post:
BoxsterLS376 introduction - LS3 conversion :) I bet it would be 'bolt-in' within 6 months.
I'm muddling through my own Audi 4.2 swap, but like most of the swaps I've followed , it is a start and stop project and isn't going to produce step-by-step instructions.
Want easy? Bolt an ABZ to a 5-speed using an LS throttle body, custom intake, and aftermarket engine management.
