Are you using the engine out of an E28?

[E30GAV]

yeah the engine is out of a 1987 M535i e28

gav sell that heavy boat anchor and get the m52

Wiring aside you do know you will have to swap the sump for an e34 item and work out how to get rid of the water pipe at the back of the head,im sure mounts are different too.

on a plus side you will have the right flywheel for the swap.

It's easier to get the loom ecu and hanress from an e34 less wiring mod's check the sticky on m30 swaps.

yeah i was told about the water pipe at the back of the head. . . .

dips the m52 is tempting!!!! when i was removing the engine. . .random person driving past shouted out. . . . 24valve it!!!!

hmmmm. . .

should it be going spare for any reason, i'd be interested in the oil filter housing / oil cooler etc. that's one thing the E32/E34 M30 doesn't have

Yes you were young boy.

[e21Jason]

e34 head has a blank plate over the water outlet so it is easy to sort the water pipe

[E30GAV]

rite so the mounts can be fabricated, water pipe i should get around that, sump should be easy enough to change. . . .just need to sort the loom out?

i have the dogleg box aswel . . .will that all hook up and fit in the e30?

[Rav335uk]

You could use the g/box

[leeparkes]

i have the dogleg box aswel . . .will that all hook up and fit in the e30?

Yes but as far as i remember you will need a low ratio diff, 2.93 or 3.15

[E30GAV]

i got 3.91 slipper on there. . . .any good?

[dips346]

i have a 3.07 if you need

Sump here £40

Part for blocking up the water way at the back of the head here too £20.

M535i/535i diffs are large case 3.07:1 units. All the M535i ones are LSD's as well.

Can this diff be used in the E30 by swaping the back plate?
