2j pisons are not forged, they are hypo... something treated, cant remember now, look it up, tehy are slightly better than the stock ones and not as good as forged.
how is my statement wrong? i didnt say it couldnt be done, i just said i dont think its a good idea, stock teh cylinder walls are too close, sorry for looking at this from an engineering perspective.\
its not ideal, no matter what you tell me.
Toyota will also tell you theres nothing wrong with a stock hg at 52lbs of torque, why dont you do that?
Goddamn, why do ppl have to be so blatently rude, M series engines are not jz's, they were built as a nice efficient 2L and stroked and bored out to shit, why do you think toyota changed the design of the jz? go look at one and tell me how close the cylinder walls are... whys that? you tell me. No wait i will, heat! the closer and thinner, the more heat. the less efficient. YOU CAN DO IT, didnt say you couldnt.
Last i checked going from an 83mm bore to an 86mm bore is pretty big difference, im not sure, and please do tell me what the thousands of an inch equates to for 2jz pistons, but i believe it to be more than .40
