Or, you can not strengthen, change the piston to hang the exhaust manifold, turbo, left his native intake manifold, intercooler, injectors 630cc, and ECU just what I do not know. Something may be wrong, please tell me.
I agree the GTE pistons and thicker head gasket would *partially* address the compression problem. However, the 2jz-gte head's combustion chamber shape (together with the thicker headgasket) is *not* the same as a 2jz-gte head. The shape of the combustion chamber & piston is referred to as "squish area", and there's a science behind optimizing squish area to maximize combustion efficiency. In other words, slapping in a thicker headgasket does not completely correct the shape of a head that was not originally designed for forced induction. Your horsepower results won't be equivalent. Oh, and don't forget about the missing oil squirters in the 2jz-ge block.

I'm not sure what you mean by the word "usilevat". Apologies - please restate your question.

Of course, the 2jz-ge exhaust ports are a different configuration than the 2jz-gte ports, so a different turbo header must be used.

Also, the 2jz-ge ignition system is far inferior to the 2jz-gte's, so you will likely need to modify it if you want to run a lot of boost.

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.
