^WOW^
If you don't know the first thing about what is different don't reply.

The block is exacly the same except for being tapped on the passenger side for the turbo oiling system (feed and drain). So are the rods ,crank, valves. Only difference in the pistons is compression ratio. The head is differant in that the bolt patterns for both the intake and exhaust runners will not swap from one to the other but a NA head will bolt on a turbo block and vise versa.
NA's have distributor ignition and TT's have coil packs. Injector size is different (330cc on NA, 550cc on TT).
The one thing you did get right was TT blocks have oil squirters, NA's don't. But most engine builders remove the squirters when they build 2JZ motors anyway.
