M90 rebuild. M56 as parts ?
Evening all, i have a 300k mile m90 out of th project car currently and it works fairly well but syncro is just about gone on 1st and it makes all sorts of noises when it wants to.
I also really would fancy a taller 5th gear, the vnt turbo makes 30 psi at 2400 rpm, so it can handle it. So im thinking of rebuilding it, does anyone have a source for parts, does anyone know what parts if any are interchangable with an m56 gearbox as they have a tall top gear. Many thanks in advance Will vg |

I've briefly looked into this. The ratios of a M56 are different to the M90 so I'm not sure if the syncros will also be a different size, but it would certainly be worth a look. I am planning to get hold of a M56 (even a broken one) to strip down and compare at some point. I actually want to swap some of the M56 gears into the M90. Let me know what you find out.

Thats exactly my plan, there have been a couple threads regarding this idea , but noone seems to have pulled their finger out to actually find out!
I will keep this thread updated with my findings, pulling an m56 out of a v70 p1 next week. |

Have you tried turbobricks? I recently read a post about this but can't remember whether anyone actually did it.

Page one has a "a friend had one built" post so with a pinch of salt and all that, but it does seem like they're very much interchangeable. |
