i wanted to know if it was possible to put a 6 speed transmission from a 2jz onto a 5mge engine and if it's possible what would have to be done pleaselet me know just curious to know what would need to be done if it's possible thanks
The JZ series engines have a different bellhousing bolt pattern to the M series engines, so you'll need a custom adapter plate to make it bolt up. You will also need a custom clutch and possibly flywheel. Tailshaft modifications will be required, and you'll also need to modify the shifter linkage otherwise the shifter will end up where your handbrake is. The 6-speed is too wide to fit in a Mk2 transmission tunnel so you'll need to either bash it out with a sledge or cut-and-shut it.
Finally, you'll want a much taller diff ratio to take advantage of the 6-speed; the Mk4 Supra has a 3.2:1 diff ratio. I doubt you'd find such a tall ratio for the F-series diff, but you could possibly get one custom made ($$$) or swap in a whole Mk4 diff ($$$). A friend of mine put a 6-speed in his Mk3 and with the stock 3.7:1 diff first gear is pretty much a waste of time.
Sounds like a lot of work just to get an extra ratio! Personally I wouldn't bother.
Of course if you have a JZ series engine it becomes a lot easier... the 6-speed conversion is still on my list of possibilities for Project 2JZ. If I can find a transmission that doesn't cost an arm and a leg it will probably happen.
all of this no matter what you do is still going to be alot of work i wanted to just stick the tranny from a 2jz onto a 5mge and see what happens without fiddling with gear ratios and and that stuff but just widen the well to make it fit and everyhting like that but don't think i'll do it but was just curious to know if anyone has actually attempted taking a 2jz tranny and putting it on a 5mge lol this is prolly never gonna happen on my budget and time schedule lol but would love to see one if it works
This is exactly my very same question as well???? What IS wrong w/ the 5-speed????
As I've told others in the past, you're NOT gaining anything in the lower gear selection w/ the Getrag 6-speeds, except for a extra gear between 3rd & 5th gears... As I've mentioned in the past, 5th gear on the Getrag V160/V161 is the 1:1 gear ratio, which is the same as our 4th gear on the W58. THE GETRAG 6-SPEED DOES NOT HAVE TWO OVERDRIVE RATIO's, it only has ONE, which is 6th gear!!!!!
If you are still running a M series motor, this is not worth a upgrade, IMHO.
their is nothing wrong with the 5 speed just wanted to find out if it would give me any kind of advantage of any sort and if all the gears would be the exact same as a 5 speed except the adding of one gear and that gear 5 on the 5 speed would be the equivilent to 6th gear on the 6 speed????
