People don't swap out the twins. Infact, you can't. They swap out the whole engine with the twins. 2JZ-GTE is capable of outputting more power than 2JZ-GE in it's stock form. I suggest you use the search button to find about the differences. Generally people end up switching to single turbo after doing the swap too.

If you want somewhere below 500 hp then I suggest you look into N/A-T. You can still acheave the same power levels as with stock 2JZ-GTE, but you would have to build it up.

At low boost (16-18PSI), an SP63 is capable of flowing over 500RWHP, while high boost and proper tuning on a larger A/R will allow over 650RWHP.

My advice is go NA-T and then if the engine goes and you really want to do a GTE swap then adapt the single turbo to the GTE. You will most likely be fine with the GE. Even GTE owners do the same piston upgrades and other such things to their cars once they target similar hp ranges.

Taken from www.sound-performance.com:

SP63 ($1050) - Perhaps the ultimate street turbo for those wishing to push the boundaries with an upgraded fuel system. The SP63 spools slightly slower than the SP61GT, but is still one of the quickest spooling single turbos available, being more responsive than most normal 61mm models (with 20+PSI available as low as 3700RPM, depending on the application). At low boost (16-18PSI), an SP63 is capable of flowing over 500RWHP, while high boost and proper tuning on a larger A/R will allow a Supra Turbo to push over 650RWHP. We have run 10.2 at 135 with this turbo on a full weight Supra WITHOUT the aid of NOS!!

what about turboing an NA with a lot of miles on it 100-120k is it worth it or does this not make any difference?

I highly doubt this. The a lot of highest rwhp people run oem pistons. This includes Mike Carlin who is the rwhp record holder (without NOS).

A few guys turboed their cars at about 130,000 miles. As long as the engine is in good shape.

on pump gas. not sure if its going to be 6 speed or auto. On supraforums they say auto is faster then 6 speed. well, not faster but it will crush a 6 speed on the quarter. i thought about getting an auto but 5 or 6 speed is just more fun to drive, you know?

On pump gas 500rwhp... I'd do a 67ptrim with a .68 hot side. Autos (with a built tranny and good stall) WILL be quicker but not faster... ie you will run a 10.0@135mph on an auto while a 6spd will need much more mph 144+ to get a 10.0.

IT depends on your use for the car.
