7M-GE swap to 7M-GTE Questions
 

I am wondering what it takes to swap a 7M-GTE engine into a 1986.5 N/A 5 speed supra MK3 with a 7M-GE currently in it. This includes, everything that goes into the car to make this whole thing work including if I would need a new set of gauges, LSD, ecu, tranny etc. I am new to this forum and have not worked on cars very much but i know about many kinds of cars and love every kind of car. I have been reading a lot about the more indepth workings of cars lately and now I'm trying to figure out some costs before I buy a car. An 1986.5 supra MK3 will likely be the car I get for a number of reasons and as a result it is the year I would like as much of that information about as possible.

Check out the FAQs section, there if a thread on swapping. That will probably answer most of your questions. Then makes some notes to do a 'search' in this, and general question section for some more answers.

But...since you haven't got the car yet, I'd suggest finding a turbo car, then fixing it up. In the long run I think you will be better off.

thnx for the idea on just getting a turbo car to begin with, i have been looking at that option. The only problem is that i live in Canada for now and to say the least turbo cars r limited at best here. As a result the swap looks like it will b the best bet when it comes to cost, especially because i have found a number of engine importers within the country.

i have been looking around like u said and i found that one of them said a new tranny but is that needed, or just recomended or what? any help on any of my questions would b great

The w58 will be good enough if you plan on staying under 300hp but if you plan building it up to well over 300hp then i suggest you get the r154 turbo tranny cuz you will definately fry that w58.

try not to buy a turbo because peaple like us beat on them and just do the 7mgte swap which im planning on doing too.

hello everybody, im the dumbass that overreved and threw my rods,

i found a 7mgte for 600, now do i need the tranny from the turbo, ot would the n/a tranny will do fine

cuz somebody is selling me a turbo tranny for 200
sum advise b4 this deal passes

the n/a tranny should work but if its a r-154 i would buy it.

i want to get around 300hp running N/A.. im doing.. intake, exhaust and cutting my cat out for now.. then probibly a down pipe.. then ill run electric fans.. and get a different underdrive pully. not sure what ill be at after all that. my friend knows a guy that might hook me up with a turbo, not sure yet tho. maybe take out my ac.. then it doesnt have to turn that too and ill lose a few pounds.

my intake/exhaust/cat will get me 15-20hp? better low/high rpm power.

i hear the w58 (n/a trans) can hold up from 300-350 hp but if you plan on putting more hp go with r-154 and if you put the 7mgte in dont forget a new clucth.

newbsupra, You going to have to do a lot more work than that to make 300hp from the na motor. And its called a header on an N/A, not a downpipe. And yes get a header, good mod to do on any car. I would suggest getting the block decked for more compression, Thinner head gasket, Try to find some better cams, And def a new intake manifold and new/modified throttle body. Its hard to find n/a parts because so many people mod the turbos up. And for the original post, Despite what it looks like, Doing the turbo swap can be a LOT of money. More so than just looking for a turbo car, driving many miles to get it, and drivin back. Aside from just the parts, you have to account for a lot of other things. Will your new motor/turbo/trans/any other part need a rebuild or replacement? will you have all the right nuts&bolts(thing a lot of people dont realize is hard to find at times), The ecu, The wiring harness, All the sensors working/included, All the piping, the intercooler, the oil lines, Youll need a whole new exhaust put on, And a lot of other stuff that you just find along the way. So trust the expert (menickleeye) lol. The only way id say do the swap is if you have the car and/or motor and parts already

how would one know if its a r154
what about the ecu,

my bad about saying downpipe. yes i dont expect to get that kind of power with just those mods, i was just listing some of what i have planned. i just think it would be funnier beating these moded cars with a n/a supra. ill eventually get a turbo, but dont have the money for now. there's a neon around here i want to beat, it will take awhile. he's running a stage 4 turbo on a SRT4 engine.. putting out 410 fwhp and 405lb-ft.. runs a 11.9 in the 1/4 with stock tires. and with all this done, before bolting on a turbo, the gain will be big.

the r-154 is bigger and in the tsrm manual section you can see a couple diffrences and on google look up r-154 images and w-58(non turbo manual transmissions) and you will be able to compare that way. (thats how i did it)

Your gona need a lot more work than youd think haha...look up defiant_7m on supra forums. Hes got a 101mm stroke and 14:1 compression. No power numbers yet thou lol. Making power is all about compression. Either by using a turbo to stuff air in or by putting in huge pistons...compression is what makes the power :)

14:1? thats awesome
a standard car is usally like what 10:1?

the N/A's are 9/1 9.2/1 I think.

over rev?
 

i thought the car came with a rev limiter so you didnt over rev the car and mess it up??? the only time i ever through a rod was when i ran a car out of oil
