But on the GE engines and turbines installed once go and blow 1.5 bar, the head and the block is not changed? Or something usilevat necessary?
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.
