M40 flywheel into M42?

[eko]

Is this a straight forward swap?

Basically my clutch is starting to feel sorry for its self,not quite slipping yet but shouldnt think it will be long so i was thinking,will it be worth fitting the M40 flywheel while im doing the clutch?

Is it as simple as fitting the cluth/flywheel or will i have problems with the gearbox not fitting anymore?

Anyone got any experience of this swap/any advice?

I do have a 316i(M40) that im breaking so any parts i need i can scrounge from that?
(Apart from clutch which ill buy new)


Thanks in advance

yes should fit fine, Its lighter than m42 as well! (I assume you know this though...)

there's varied info on this, i've got one i'll be trying when i do the engine swap so can let you know definitively.

Im sure ive read that the 318is box has a different size input shaft so dont know if this will cause problems?

Anyone else add anything to this?
Would like to do it soon before i get rid of my breaker!

well if your doing the clutch then all i can suggest id that you offer the parts up to each other to see if they fit.

I agree but im not taking the 316i apart if i dont need the bits and i dont want to buy a M40 clutch instead of M42 clutch if i dont need to,unless they are the same?

AFAIK you need the m40 flywheel, clutch and pressure plate. havent heard about the input shaft thing tho.
