how much is my engine worth?

[tommi_e21]

have you decided what diff your going to go for?

[myfirstE21]

not yet, at the min my car has a standard 3.91 diff welded up, i know this will need to be changed though.

what diffs are a good fit and can take the power?

[tommi_e21]

e12 diff but you will have to heavily modify the rear from and mounting bracket on the car

[myfirstE21]

Is there nothin that's a easier fit as i have just had my rear beam powdercoated lol!

are e12 diff's readily available?

[e21-Mark]

No, not really. Jason is working on e30 conversion which might be of use?

[myfirstE21]

excuse my ignorance but what is weak about the standard diff? with a e12 conversion do i need to change shafts etc too?

Propshaft gear cracks and the half shafts mate up easily. no mods on that.. worth doing imho....

in my experience its the cv joints that give up before the diffs. ive broken 3 cv joints while drifting. the cage in the cv joints splits down the middle and it spits all the balls out.

another beauty of the welded diff (i might add) is when this happens you can still drive back to the pit area, in 1 wheel drive, for a quick swap!

LOOOL thats because you welded the diff giving more stress on the halfshafts..... not everyone is a weld diff drift master like you
