Re: What is a 2JZ-FSE??

Limiting factor is definitely the exhaust ports. There is very little to be gained by increasing cam lift with std ports. Also, std valve springs coil bind at ~ 9mm lift (std lift ~8.3mm) so going for more lift means you have to buy into new springs and a shim under bucket setup (about $1K) - on top of cams (another $1K). I suggest increasing duration to about 270-280 degrees and leave lift alone. Adjustable cam gears are a must. Std ECU should tolerate this - anymore will likely need an aftermarket ECU. Mandrel bent extractors and a decent exhaust will help (no more than 2.5" - roughly $1K), and, of course, a good intake.
Here is a nice link to a fairly worked 2JZGE: berserk NA 2JZ
It puts out 400 ps (~380 hp) and is reasonably similar to mine. I'm running smaller throttle bodies (48mm rather than 55) and slightly less duration cams (304 vs 312). I suspect the compression is sky high.
EDIT: The article has some errors - they are EFI throttle bodies not Weber carbs.
