Different 7mgte's

[z287mgte]

i bought a new 7mgte for my supra.. long block and it was different from my old block.. i have a 88 supra..guy before me put an engine in.. just confused and just wanted to know what is what..also which parts to switch to the new engine if any.. first off.. the throttle body is different.. new one has one vac on top and old has 2.. engine mounts are different, new block has a goldish color on the inside of head. also thermostat housing on old has 2 vac ports and new has 0... and last the exhaust manifold is different.. old one looks beaten and new looks smooth.. please let me know whats going on?

Sounds like the engine is from an 89+ supra, the reason for the different motor mounts. As far as the throttle body, auto's had different throttle bodies than manual cars. Try posting pictures, it would help us determine what parts you need to swap.

wish i could give pics but its at home.. just trying to find out differences.. which one might be newer??

sounds like you have a JDM 7MGTE (which makes it used lol)

top one is the newer engine that i have and the bottom one is the older one.. is there a big difference - which one is better

Well, if you have an 88, and you say the one you just purchased has different mounts, than I would say the one you just purchased is newer based on the mounts. However 89+ mounts could have been placed on a pre 89 engine.

Another way to tell is to look at the block. Here is thread describing some of the differences.

I believe IJ wrote a thread about the the differences, I cant seem to find it at the moment.

Need to see the sides of the block to tell.

sorry to jack the thread, but what about internals? are pre 89 and 89+ turbo the same internal parts? (other than the crank)

 

[z287mgte]

thanks that helps a lot.. i looked but could not find what i was looking for until now

btw sorry to go off topic it says your location is Ohio and notice the car is RHD is there another Ohio outside the USA? or is that just a picture you used for refrence.

 

[z287mgte]

its just a pic i used as a reference..yes are there any other differences between engines?

No EGR components on a JDM motor (They should be installed if the JDM motor didnt come with a JDM ecu) , Coolant Rail is different, oil pressure sender is different (should be changed to a USDM version), throttle body should be changed over to USDM version. Other than that, they are identical.

^ He pretty much nailed it. You'll also need to switch over the thermostat housing to have the extra port for the BVSV.

The oil pressure sensor on the "new" JDM engine is also different. You will fry your guage unless it's swapped out.
