Use 7mgte block as a 7mge??

The GTE has lower compression pistons, so, if you've used stock spec pistons or ones with an even lower CR it'll be a dog of a N/A. The oil squirters are a bonus.

As for mounting parts everything I can think of will fit fine, but the GTE uses two knock sensors bouth mounted outward from center and the GE uses only one mounted ner the center. To use the GE electronics you'll either need to use two knock sensors and splice the wires into the one line that runs to the ECU OR you'll need to drill and tap the center boss for the GE's knock sensor.

Intake cams are different, you'll probably want to swap those as well.

Motor mounts are also different.

Other than those few things there's nothing else that isn't evident.

Oh, and you'll want to run GE spark plugs

Thanks alot, I have probe forged pistons that have the stock spec compression, but a lil bigger. As far as the mounts, could I use GE mounts and work on them (weld etc.) Or am I going to have to fabricate some? or do I just find some GTE mounts?

As far as the cams, I have the GTE head with cams and the intake. Will that work withe the GE stuff?

[cre]

yeah, just swap the mounts.

I highly recommend swapping the intake setup over.

cams will probably be fine. The intake is the only different one.

I really appreciate the info. So the GTE intake, head and block is the way to go?

I should be good then, as I do have that stuff. Thanks a lot and I'll be posting some pics of the work as I go along. (If I can figure out how)

Again: GTE- Intake setup, head, block (splice GE harness for sensor), and mounts should work with the GE car and everything else.

Thanks

i have a turbo setup off a 88 supra and from what i can see the wiring harness is the same other than the fact of splicing into the igntion system for the fact of it not being the 90 model where there is more sensors. can my harness work and will it plug into the gte ecu?? And i can just run electric fans rather than the clutch fan assembly you said i should swap over right?? And i also belive that i have to change over the intake manifolds to, right??

no. GE intake. GE mounts.

posted from my phone. sorry for any typos and poor grammar

[joshtexican]

Ok, gotcha man. So the GE intake will fit my GTE head. Cool deal I really appreciate the info. I will try to keep posted on this preoject.

Thanks again

[cre]

there are a number of supporting components you will need to swap over, no short cuts, or you will lose even more power

[BDRT103]

ok thanks and why when i pull my spark plug wires do i see a small amount of coolant? And what should i do for the oil return and oil feed lines to the turbo? and can a just splice into the coolant lines also? and i also dont need my maf anymore correct?

There are coolant plugs under the spark plug galley cover. The four giant hex bolts are plugs to oil passages, you need to remove those to get to the coolant ones below the cover.

Oil feed is easy, there's a plugged 1/8 BSP oil pressure port between the oil pressure sender and the thermostat neck... actually, it's right behind the thermostat neck.

The return is troublesome. You need it as high as possible, but there is NO drilled port for it. The two possibilities are having a machine shop drill the boss (as it is on the GTE... MUCH preferred!) or drilling the oil pan as high as possible and welding in a bung... this MUST face a main, not a rod or weight and it MUST enter angling downward (it is a gravity drain).

Coolant's easy, there's a bypass which is employed to relieve suction on the thermostat that's on the thermostat neck. You'll notice it by the huge banjo bolt on the right side of the thermostat neck and it goes down to one below... ad hose so that that tiny circuit now runs through the turbo.

I have no idea what the hell you're talking about... First, you don't have a MAF... you have a VAFM (there is a difference ). Second, the GTE has a KVAFM. The only 7M's which didn't have one of these type of AFM was a certain model race car (which never left Japan, AFAIK) which utilized a system which calculates air mass based on temp and manifold pressure like the 1JZ-GTE and 2JZ-GTE use (2JZ-GE uses a KVAFM).

You can delete one through the use of additional hardware, but without any such devices you'll have an AFM.
