Rear drive only 5 speed for swap project

[hotrodln]

We have an old BMW 325 with allot of miles on it and i am looking into posibly swapping a TT engine into it....i've rebuilt two of these engines now and i think it might make a cool project....i don't know enough about other mitsu platforms to figure out what manual transmission might work in a regular front engine, rear drive format.....there must be a gear box that would work??? from a truck? minivan? anybody with an idea? thanks

Mitsu Mighty Max should mate with an adapter plate. Be advised that plate is going to be hell to make, our 6g72 has a very odd shape because of the clearance needed for the water housing.

The transaxle is known as a D-50. Ambitious project...keep us updated if you decide to do it.

i wasn't looking for a transaxle, i'm looking for a regular 5 speed like a standard rear wheel drive car would use.......is there one? I remember years ago people wanting to use the cadillac northstar v-8 in rear wheel drive cars......i think they used a buick transmision to pull it off.........wondering if there's a mitsu equivalent?

I mistyped with transaxle. The Mighty Max is a 5 speed rwd(or 4wd) truck, and in at least the 94 models used the 6G72 sohc. The D-50 is a 5 speed manual tranny. You're going down an uncharted path, there is no easy explanation...as no one's done it before with a BMW( I suppose someone may have done something with one but not that I know of right off). I'd recommend searching the Starion/Conquest forums for potential info.

Well so the D-50 will bolt up to a 6G72 TT? that's what i needed to know.......i'll bet they aren't too expensive....as for the swap into the BMW.....they've already done lots of different engine swaps into that car.........big v-8's etc etc....i've done swaps before....had a V-8 VEGA in high school and a v-8 pinto that i've done....now i've spent allot of time on these TT engines and i think it would really wake up the old BMW! i have one project to complete before i start it.....i'm installing an 86 T-bird turbo coupe engine in a 1974 Pinto.....yup i'm still drivin em! anyways thanks for the tip!

It's not going to be direct, there is no direct bolt-on rwd tranny.

ok i thought the d-50 transmission was a direct bolt on?

I said in my first post it would need an adpater plate. Not all 6g72's are the same...

Odd but very cool. I've had some off the wall ideas but far to involved to ever be completed by myself.

I believe Gil fron GCtech ind in houston can have an addaptor plate water jetted so you can bolt the Nissan 350Z trans to the 6g72. He offered one to me not long ago as I was thinking of going RWD in the NA.
