I would try it with a Boxster first. They're becoming a lot more affordable and its a very similar chassis.
http://www.renegadehybrids.com shouldn't have too much trouble with it if they can get it to fit.

it could be done no doubt, but you'd have to hack up a lot of stuff. The cover above the cayman engine simply doesn't sit high enough to stuff much of anything under there. You would have to raise it up a good 5 or 6 inches, then find a way to insulate the sound and heat if you don't want your interior to turn into the worlds loudest oven. and that's not even diving into transaxle and exhaust woes.

I spoke to Renegade Hybrids the other day. The owner was VERY friendly and knowledgeable.
He said the new all aluminum LSx engines alone only weigh about 50 lbs more than the stock Cayman engine alone.
So, we both agreed 50 lbs on exta weight is a small price to pay in order to DOUBLE the power.
He said that they have not placed a LSx engine in a Boxster yet, but feels the Cayman will be a better platform for the conversion that the Boxster.
He is willing to move forward with development, but a Cayman needs to be located for the conversion. A Cayman with existing engine or other issues would be preferred.
So, if anyone is aware of a Cayman that has a blown engine or other issues that would be a good candidate for developing a LSx conversion package, please let Renegade Hybrids know.

I looked into a 99'-2001 with a 3.4 with a cracked sleeve to do this before i started on mine in Oct. 2006. I like the early cars because of their weight and stealth factor. Big time sleeper if you do it right and make it look stock still. I'm in the process of looking for a stock decklid and stock 16'' wheels for the F/I install this December.
I'm thinking it is possible. My buddy has a 2002 C4 cab i'm trying to convince him to let me do the swap on his. Fun
DO IT. There are NO drawbacks to this swap. I'm now 2840 lbs...stock is 3175. The car outruns 636's no problem, even with a bad tune. I'll start bullying the liter bikes around here in the spring once the twins go on. Cheers
Good luck!

It's stock. Just need to fix this damn exhaust leak
Look at my sig. Man, if you're a pguy you'll hate my car. I've come out to the car in the parking lot with SPIT on it. Seriously. People take this stuff a little to seriously. It might be because the car is so DAMN loud!
Good luck dood. I PROMISE you won't regret the swap. There aren't many surprises better than seeing an aluminum block in a 911. Usually gets more attention than the local Ford GT and Caterham at get together's. Love it.

Wow I was tired today when I posted that, I thought your sig was two seperate cars. Thats SICK. Are those 996 Turbo wheels? Im not a porsche only guy I love all cars even slow ones. Do you post on 6speed? Im only there to read about 996 turbos, one of my favorite cars. People might of spit on it because its a Porsche not because of he power plant.

Your g64/20 trans couldn't handle the torque but your front transfer case can according to evolution motorsports. Swap to a G64/21 996 turbo box and you're good to go.

I still say your car is sick as hell lazylongboarder.
The 964 has always been my favorite Porsche and their crazy high repair costs and minimal power made them seem unreasonable.
I would definitely get one if I was dropping in an LS motor though.
