It's an expensive conversion. The technically mental members here frequently talk about costs in the region of £5k to do the job properly.

Have a read through that, has a lot of usefull information in it.

IF you are serious, i know where there is a plug 'n' play conversion for sale! you would need a clutch, a propshaft and a radiator and £4k. or (at extra cost) it could be done as a drive in, drive out conversion if needed. it is a well know and proven engine conversion and it makes just shy of 300hp

i am very serious about this conversion as had a 325i before an it jus needed a lttle bit more power!! so got my hartge 325i cheap an wanna have some proper bhp in it as i completely restorin it anyways.. just dont hav that kinda cash about me so me an my dad will do it..

would love a step by step guide thou as in what all needs doing as we go and im sure someone has it on here??

thanks

It is 5-6k DIY..

No step by step as it is a complicated conversion there are many ways to do it.

Don't think you will do it on the cheap, as you wont. End of.

where can i find this convertion?? and where could i have it done?

Say you get the engine and gearbox for 2k which includes exhaust manifold,ecu etc

Sump
oil pick up
engine mounts
Radiator
electric fan
propshaft

What else is needed?

LHD or RHD?

Diff
Servo
Master cylinder
Oil cooler
Exhaust (inc modified manifold if RHD - £1300 from BTB for the manifold - THE ONLY PROVEN OPTION)
Coolant hoses (inc 2x 90 deg Samco's)


Off the top of my head, loads of little bits also needed as you go.

You'd be daft not to swap the clutch/flywheel/release bearing whilst it's apart

Can be fitted at the Suffolk/Essex border..

the bmw parts list is endless and you will need a few custom parts. trust me mate, everybody (me included) thinks they can do it cheaper but at the end of the day it will end up costing £5-6k. its not just a figure we plucked from thin air.

The Exhaust is a big problem as the manifold from the donor car doesn't fit. You can't just knock one together and hope it works because the M3 lump is very fussy about the way it gets rid of its gases. If the manifold doesn't flow properly the engine doesn't give up it's quoted power output.....apparently.

No apparently about it.. They are highly tuned sensitive lumps (bless..) The manifold isn't an intricate equal length design for no reason.

You can get away with just modding the bottom part of the S50 manifold to clear the ARB (if you are prepared to lose sound proofing from the bulkhead and give it the good news with a hammer)

Bodge

^^^it can be done on a m50/2 the bigger the hammer the easier it is, but i doubt this would work on a s50 as the head is wider and would leave the collectors right in the way of the steering linkage.

LHD only...

RHD it leaves nowhere for the steering coupling to run..
