All in all, the E36 is a massively better chassis in every way, except that it comes with BMW trim and driveline installed. My last round of E36 projectitis came when I contemplated putting a SBF in one and ten seconds of Googling revealed that's already a thing. Think of it as the Daytona Coupe to the Cobra roadster, if that makes you feel better. It's occurred to me that the E36 today is in exactly the space that early Z cars were in when I was in college and couldn't afford to do any of this stuff. Except they're better in every way, not to mention having galvanized unibodies.
What turned me off from the 1UZ was a reliable source telling me that if you port the heads to hell and back, they may flow almost as well as a stock 2JZ. The LS engines are good, but they are bigger, and just a little bigger can create all kinds of headaches and compromises.
The S54 is a pretty good engine, but doing anything to it (as well as maintaining it) is crazy expensive. It's also expensive to buy in the first place, and it's a big, long, cast iron pig. Also, stock M3 exhausts sound tinny and lame. The Honda K series is massively lighter and can make nearly as much power from 3/4 the displacement, while being relatively simple to work on and really cheap, once you solve the problems of getting it installed. Also, being leaned over ~30 degrees to the exhaust side makes it nearly impossible to build a good, high-performance turbo manifold. There are lots of bad ones you can buy...
As Thomas Sowell says, there are no solutions, only compromises.
Hey, [MENTION=6108]JRB[/MENTION] (or anyone else), can you school me on XJ Cherokees?
