The exhaust port pattern is not the same on the non-turbo 2jz-ge head, as the turbo 2jz-gte head. In other words, a non-turbo exhaust manifold won't fit.

In theory, you could do it with the header from a single turbo kit, and then get a custom downpipe made. If you had an exhaust housing with a block-off plate (and I do happen to have one of these handy!), you could use a full single turbo kit (without the turbo) and the downpipe that comes with the kit would fit onto the turbo exhaust housing with the block-off plate.

It has been partially posted, but I'll give you some of the important differences here. You'd have to pull out the complete (fully assembled) 2jz-ge (non-turbo) engine, transmission, differential, and suspension and replace them all with TT parts. You'd have to pull out the abs braking system, calipers & rotors, the abs ecu, the primary ecu, ingnitor, resistor pack, and primary wiring harness, and replace all of them with TT parts as well. The rims would have to be changed too (16" to 17"), but of course that's relatively minor. I'm sure there are other items as well, like the fuel pump, the fuel pump ecu, stereo system, etc., but I think that's most of it at a high level. Other forum members please feel free to post additional items that would need to be changed. Generally speaking, almost all of the 'working' parts of the car are different - so although they look the same, they are very different vehicles beneath the surface.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
