Well. I guess when I finally find a turbo for myself and with my luck, it will need rebuilding. So when I finally take it apart I will finally get to check out the parts to see if there is a difference, but until then, thatnks.

The heads are basically the same, there are 2 different castings with some differences inside the ports to the cylinders on the intake side. The 89+ N/As have a slightly more aggressive exhaust cam. The pistons are higher compression on the N/A, but not by a great amount. There are a few differences on the blocks as far as the placement of holes and such, mostly for the oiling system relating to the turbo. The 7MGTE block has oil squirters for the cylinders, which the 7MGE lacks. The oil pump has a higher capacity "intake" on the 7MGTE.
