that's an interesting question....i think most people just either swap the GTE or go NA-T. If you don't mind my asking, how much did your setup run you? I would guess you could run a piggyback similar to NA-T but i'm not the expert.

Sorry to break the news but the Supra manifold won't fit on the Gs300 engine (non-gte 2jz). You should look into just buying a single turbo manifold and installing a small turbo like a 61mm etc....

As far as fuel you will need an upgraded pump, (walbro 255 for example) as well as larger injectors (the Gs injectors are tiny) and someway to control fuel, at the very very least an Apexi AFC but preferably a Haltech F10x.

well theres a lot a of differences betwen these two motors .....the turbo block has oil squirters in them lower compression pistons con rods....but if youre asking about the exhaust manifold fitment they would not interchange because of the differences in bolt pattern and ports not lining up ...........do u have any pics of the manifold??

a while ago i tried to have an old tt manifold with turbos mounted up on the gs300, it became apparent it was going to be a pia. i highly suggest going single on the vvti ge motor. i'm was running 8lbs daily on a fairly cheap set up and loved it but my tune some how dropped out of the system and it's going back to na for a while till i have time to chase down gremlins. the cost of making the tt work would have countered the saving on parts factor
