Is there any major difference in the na supra m4 vs the twin turbo model? Engine wise.thank for ur time

 

Turbo model has a diffent head Block has forged pistons and i think crank too also oil squirters.

You trying to turbo an NA?

 

^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.

 

Thanks guy , yeah i want to turbo a na supra

agreed,

i have a NA-t, there are some differences, but the BIGGEST one is the 5 speed vs the 6speed. the turbos have 6 speeds in them. Now the turbo kit for the supra is not all that bad, but then you will have idle problems with the AFM, and the 5speed to 6 speed is going to run you about 5-7k. mine is costing me about 6k right now. also the intake manifold on the NA kinda sucks
