Tranny Swap

anything will fit with deep pockets.
short answer, no. it won't simply bolt up.
long answer, yes, but you'd have to make a custom bellhousing, driveshaft, transmission mounts, get a new rear end, as the stocker in any MK3 is useless with the getrag's ratios. first will be un-usable, and 6th will have a higher highway RPM than an R154 (stock turbo 5-speed tranny)
you'll also have to cut another hole in the tranny tunnel for the stick to sit further back, thus making a custom center console, or at least mucking around with yours to make it not look like a robber tried to steal your coin pocket.
AND, you'll have to take a hammer to the tranny tunnel to widen it so the getrag will fit, not to mention costom crossmembers and transmission braces, and custom slave cylander line.
so, yes, and no.

why won't first be usable too short a gear ratio? and why would i have too make a modification for the shifter the MK4 uses the R-154 same as the mk3 the getrag wasn't even introduced until 95/96 i believe. the only real differences i could obviously see is the clutch system, flywheel, and starter are different. i wouldn't have to get a custom clutch line unless diff. fittings count. i know it won't simply bolt up a project this big isn't simply going to pop on. shouldn't the bell housing bolt pattern be the same if the Mk4 uses the R-154. Have you done this before i'm just wondering. on all this stuff i don't doubt your knowledge at all keep all comments coming i appreciate them.

the mkiv does not use the r-154.
http://en.wikipedia.org/wiki/Toyota_Supra#Toyota_Supra_Mark_IV_.281993-1998.2F2002.29
the n/a comes with a w58, the auto is the a341e, and the manual is the v160 and v161.
if you want a badass trans put a GM auto in there, but if you want a badass manual then the r-154 is just fine.

no, the MKIV does NOT use the r-154. it uses the v-160 (getrag) for the TT versions of the MKIV. N/A MKIV's use the new style w-58.
why WOULDN'T custom fittings count? if anything is done to the line that's NOT stock, then it's custom.
no, as the MKIV did NOT use the r-154.
as i mentioned above.no, but i looked into it, and found that the r-154 is a MUCH better choice for our cars.

How hard is the GM auto to swap to the supra auto? How are they geared differently? I mean how does it compare to the supra auto? My auto is acting up a little right now. My wifes car is turning 2800 rpm at 85mph. (89) My 91 turns 3500 rpm at 85mph. I think my overdrive is out. It seems like it shifts through all the gears perfect, but it deffinately turns more rpms in high gear than my wifes.
i apologize for my stupidity and i don't mean by any meens any offense. the reason why i say the N/A Mk4 uses the R-154 is cause when i looked up the part #'s for the 3 and 4 the 5-speeders where the same R-154 even from Toyota and Driveline or Drivetrain.com don't remeber which one it is called. EVERY one that i talk to says the R-154 went in the earlier mk4's. also i've only heard of the V-160's what the diff. between 160's and 161's?. The V-160 from Toyota brand new costs 5g's rebuilt from autozone(cheapest)3,460 i believe with a 1200 core!!:aigo: ouch. anything else yall cn think of that would be a pain in my rear for doing this? as for using one of the Generals trannys there's a ford probe with a 2Jz-Gtte using a corvette auto tranny it's really wicked. my friend has a one of the few rare turbo probes and discovered the dude while surfing around for ideas about his car.

you're still a little off base here. the N/A MKIV's don't use the r-154 either. they use an updated version of the w-58.
everyone you talk to is wrong.
i've never heard of a v161. i highly doubt there's such a thing that was put in a supra. why are you so interested in a getrag swap into your car?i think it's pretty much been covered. that car sounds pretty wicked. turbo probes aren't rare. they're pretty slow, too. the turbos on those things are like hairdryers...

then by all means, go for it. you'll have some custom work to do, and some custom parts to make/have made. if you've got the money, i say go for it if you want it.
i love driving six speeds. i just like shifting, haha. post pictures as you go!

what rear end would i have to use? what final ratio would be best i looking for straight line performance don't really care about raod course. i know a 4.16 works BeAuTifully with the R-154 in accordance with 1,2,3,4,5 gear ratio's being tuned as well but i haven't really foold around with a six speed ratio. oh and i forgot to post this but i guess turb'd probes aren't rare ifyou also include the mazda 626 or MX-6 in which the motor came out of.
Something in the Low 3's ie 3.2:1 would be good but doesn't exist.
(unless you happen to have a 9" in your Mk3 )

haha wow the thought of ford making it into a toyota kinda funny but that rear end is legendary.
wouldn't the stock mk4 rear work it like a 3.4 if i remember correctly.

No idea how you'd get it to fit.....
Guess anything can be done I'm just finishing off my 9" install here and run a Tremec TKO trans.

now were making an MK3 a ford. IMO thats a bigger sin than making an MK3 an MK4. now do 25 "hail mary's" and 4 "our fathers"....
Well I've trashed 2 Mk3 Diffs in the last couple of months without a single launch on slippery tires 1 being a rebuilt Torsen with 4000 KM's on it so what do YOU suggest I do? hmmm89mkthree said:
