Hit up N/A Camry Sleeper. I think he has done this. IIRC he had to pound in the runner for the #1 cylinder to clear the alternator.
FYI there is a lot of potential in these little four bangers, again N/A Camry Sleeper has done a lot of research on all motor power for these motors. Rapeacivic has a turbo 5SFE in his car. As far as mileage goes, I have just over 230,000 on my wagon and beat it like it owes me money everyday of the week. My wife's car went to 331,000 on the original motor and would still be running it if her brother hadn't "borrowed" the car and not checked fluids.
The single biggest piece of advice though is to ensure the motor is tip top with no leaks before you start playing with it.
