S54 swap questions and concerns

[mitchlikesbikes]

from what i have read a lot of people run a 3.25 from an e28 when rocking the ZF 5spd. that's what i plan to run if i run that transmission at some point

3.73 is wayyy to short for 5 speed. I just swapped in a 4-clutch 3.23. I used UUC m3 flywheel with e34 m5 clutch. s54 starter works fine

Use flywheel/pp/clutch from whatever trans you are using.

I have a built 3.73 for mine but am using the E46 6spd so something a bit more conservative... perhaps a 3.46.

EWS should be coded out in DME. PM me if you need any coding services.

Hmm I was gonna go with a 373 but now I'm not so sure. I only decided to go 5spd because trans is easier to source and more affordable.

Pm coming ur way soon thanks

Can I use the s54 starter with the zf? I read somewhere that the e36m3 flywheel will work with the s54 starter, is this correct?

On my s54 swap I used a 320zf with e36 m3 clutch kit. My s54 came out of a Z3 M e36.

My questions:
-which flywheel/pressure plate/clutch to use.
-which diff?
-do I need the ews model?
