&M-GTE head on the 7M-GE
 

ok i found a thread on here that talks about it but cant refind it. and was wondering if this is possible? for better air flow and was wondering if i put the Brian Crower Stage 2 Cams on if it will be better or just hinder? and looking for a good description on why i would be bad or if it will work? im not looking to run the GTE distributor just trying to get better air flow by using the vortex rather then the vein air flow.

Well the stock 7mge cams r better then the turbo cams they r more aggressive but if u at putting the stage 2 cams it would be good

i was wondering the same thing and you have basically the same year and engine i have thats awesome and same time too i just got mine also

lol i have 2 an 86.5 and a 87 both with the GE engine though the 87 wont start she wants to but wont and so im gunna rebuild and this is what im asking about the head and if it will help with air flow and give better performance.

so then better air flow with the vortex would work and no issues?

GTE and GE share the same head. Only difference is one of the camshafts (exhaust, I believe).

Basically, use your GE head and save money

I'm guessing u can put the swap in vortex I don't know but if the cams have more lift and longer Duration more air flow

they dont look the same the GE uses the vein looking throttle body well the GTE uses the vortex... and thats what im wondering about if u put the vortex on the GE if you would get better air flow.

and if its not the head im thinking of can i put the GTE's plentuem i think its called on the GE? and srry if i spelled that wrong and i probably made a complete fool of my self here at any rate lol.

Oh, okay. Those are the intake plenum's and the throttle body's.

The GE intake utilizes the Toyota ACIS system (info found here), whereas the GTE intake does not. Without this system, you will likely notice a decrease in power.

For example, 7M Cressidas are rated at about 15hp less than GE Supra's. Cressidas use an intake design more similar to the GTE than the GE.

Here's a Cressida 7Mhttp://carphotos.cardomain.com/ride_...0002_large.jpg

so then vary vary bad idea to put that plenum of GTE on the GE ok thank you for the info! im trying to get the GE up as high as i can with out going turbo. im not one for turbo's.

And the ge pipes had 2 vs 1 I think the ge intake would move more air then the gte pipe would with out a turbo forcing it in

the cressida looks like shit lol!

ok that makes sense. so with the stage 2 cams cold air intake and posably a 75mm tip and pipe with boring over by .20 or .40 how much hp gain would that get granted boring over costs alot and i plan on rebuilding the GE anyway.

so if you put the vain throttle body and plenum on the GTE it would get better air flow?

not being negative but if your not into turbo's why did you buy so many supras. Nissan would abeen a good bet.

ok the first one i got i got 2 yrs before i got my license. it took $900 to get her running. as soon as she fired i fell in love with the MK3 plus as soon as i saw her being towed into the drive way i loved the body style. which is why i wont go MKIV ( dont like how 93's up look ) and as iv said when i get the 1990 supra i want ill go balls to the wall. and rebuilding the 7M-GE and restoring the 87 i have will give me a good background of how to rebuild the engine and will help in the long run when i find the 90 supra with the 7M-GTE and the r154 trans. im just trying to stay away from the turbos cause of the added problems there could be. till i can understand the engine from the inside out. plus i only like the nissan skyline and thats a hard car to find in IL.

I think you need to go take a 7mgte for a test drive and you will forget all about the 7mge. I drove my friends 7mgte the other day and once you hit boost you will be addicted. If you are going to all the trouble of rebuilding a 7m why not make it a gte. A 7mgte stock will beat out a modified 7mge anyday. As long as you take care of the main wear items there is no way a turbo should not be as reliable as a na. I did the same thing with my na and it is still slow compared to a turbo.

The intake manifolds are different because the turbo forces air while the na sucks it in and I think it is the intake cam that is different.

im sure it is lol. but with the mods iv picked with getting the GTE it would make the total 11,600 something with out the body. and as iv said ill wait to go out when i get the 1990 supra i want to get.

the heads are the same. the gaskets for intake and exhaust are the same for turbo or non. even a 5m head will fit the 7m (and thus the 6m), but i believe you have to change the pistons to match the head.

both cams (IN and EX) are different from what my interchange is showing me. from what ive seen around and heard, the ge cams on a gte give you about 15-30 hp gain, i guess it depends on if using new cams or used cams.

how can the heads be the same if the GE uses a distributor and the GTE has coil packs...? would there be any issues with the GE if you put coil packs on it instead of the distributor?

the gte has a cam position sensor that goes where the distarbuter use to be

so if you get ride of that you can put the distributor there? say if i got the GTE head from supra store i could do that?

yes shoudnt be any problems

sweet my problem solved! thank you.

glad to help, but the valve covers are different from ge to gte aswell, but they are swapable. the diff is the gte covers have the mount and indent for the coil packs and the "3000" pipe, where the ge covers have the indent for the ACIS manifold
