gte and ge

lethalwithasupra · 12-09-2005, 10:35 AM

been wondering about doing this for a while and then found a few similar posts so ok ill just go ahead and ask the dumb question.

i own a half dismantled 87 turbo 7m auto supra that prolly wont ever drive again. what i was thinking about was to transplant the loom, coils, manifolds, turbo, intercooler, ecu, etc into a n/a manual supra. non turbos being cheaper and all.

how similar is the ge block to the gte ? i'll need " proper " boost - 8 or 16lb on a switch, injectors off some 4.1L ford or something, fuel pump to match. heh nothing excessive. are the heads very different ? old head has been blown twice, dunno if it's any good. i keep hearing that the turbo isn't meant for much over the standard boost, does go well after an upgraded wheel ?

don't really want to slap any turbo on some piece of shit to make it rev harder, really want a manual supra that goes like my baby would if she wasnt such a sleepy kinda beast. and don't want to mess with pedal boxes and clutches and mountings too much right now.

sorry for the rapid fire Qs.

from what i know the ge block is the same as the gte block...assuming ur talkin about a 7m....i think teh only difference is the internals...the pistons, rings, rods, and pins, u can swap a lot of the stuff from teh ge motor into the gte motor without much of a problem, yea change teh head gasket...itll save you a lot of time and trouble in teh long run

is it ok the swap the pistons and rings?

SupraMan1784 · 12-12-2005, 07:17 PM

you could swap ge pistons and rings into a gte...but why? go to a junkyard.. get some gte rings and pistons...though rings i would recommend replacing them at this point, the gte motor is built to handle boost, not the ge...you could put them in but i dont recommend it...i would rather put in components that can handle the boost, i know people are gonna bitch and moan and say that you can run stock boost on ge pistons...you could...but this is my input, let us know what you have planned

j3pz · 12-12-2005, 11:25 PM

oh cool i just didnt know if it was a good idea to put in a set of pistons from one motor to another. getting new rings make sense to me.

Put in a metal headgasket while you're in there. The difference in the pisons are the compression ratio. GE 9.1 ? GTE 8.4. You can boost more on the turbo pistons(safely). Also one of the cams is different, but interchangable. Lots of stuff I'm missing, I'm just trying to remember... I'd know more if this was the path I was going..

I think suprragirl mentioned something about a car she had with N/A pistons and a turbo that seemed to run pretty well. I think she mentioned a slightly lower boost though. But it did work.

ya im sure it will still. look at hondas and stuff, all they do is just throw on a manifold and they got boost. they might upgrade internals but its basicly the same idea

Bit of a street racer, I guess. I'm told they're fast. Delivering it home with a friend driving the Supra for the first time. I drop gears and make a scream from the twin pipes flowing down this pony's flanks and it takes off like it's tail's on fire. I look back when the Honda gets to its tap-out and the Supra's only two lengths behind. No one I've let ride my bike has told me its slow, they've all loved the thing. That car is a good thing indeed. Last edited by lethalwithasupra; 12-09-2005 at 10:49 AM.
