1jz??????

Dejvid1785 · 09-21-2006, 03:19 PM

Does anybody what kind of transmission is used with the 1jz and what kind of turbos that engine has. I was also told that the 1jz gives you less issues with overheating than the 7m-gte. Has anyone done a 1jz swap into a NA body?

Dont quote me on this, but i think the 1jz comes with the same r154 as the 7m, and a slightly tougher automatic. Someone correct me if im wrong. And overall it is a better stock motor than the 7m, But i beieve the 7m has a lot more parts available and is a lot cheaper. It is also 3 liters instead of 2.5 so you have a little more torque and power cause of that once there both modded. But the 1jz is supposed to not have any headgasket problems like the 7m, But i would still upgrade it anyway, as with any high boost motor.

theyre almost identical engines
except for the fact that the 1jz came with twins
and i dont think it has the headgasket problem

but with the 1jz the aftermarket/part support isnt as strong as for the 7m
but when it all comes down to it, i think it depends on a person's preference

It uses the same 5 speed (r-154) with a different bellhousing.

Manual trans is an R154 like Nate and ISPHIUS said, and the auto tranny is the A340. The turbos are the CT12a.
