yes i saw that part of forum but it dosent really answer my questions in one

ideally id like someone who has done an s 50 fit to say

engine mounts blah blah
gearbox blah blah
ecu blah blah
move air box etc etc blah blah

that kind of idea

Not as many "sticky's" in there compared to the M50-M52 section,

would be nice to see a write up of What parts are best to use,

and how people have done the wiring etc etc

[jwgmiller]

yes thats exactly what im looking for a general report on ins and outs of the fit

[e21Jason]

it bolts up the same as the m50 and uses the stock e36 m3 gearbox, air intake clearance with the brake servo and the manifold are the major issues

[jwgmiller]

current engine is an m20 b25 not an m50 ! so how does the s50 compare engine mount wise as the m20 b25 ?

brake servo not an issue as the rally car has bias pedal box with no servo

and ive seen a company that makes exhaust manifolds for around 1 k

what about wiring in the ecu sensors etc etc ?


thanks

I understand that S50 costs about £6k to install properly,M50/2 from about £500....hence the lack of 'write-ups' about exactly which bits to use!

As the engine is based on the same block as M50,I would expect that E36/M50 mounting arms will get the thing bolted into the bay,Fritz Bits will supply a suitable manifold,'just' leaving you engine wiring and gearbox to sort out.

If you would care to start/keep updated a project log,you will be suprised at the amount of practical help that this would generate.

Good luck with your project.
