E36 M50 -> M52/S50/S54 Swap

[1-Bar]

Just searching through other bimmer forums is giving me a headache, just wondering what locals have done and what problems/issues they have run into.

Some info on me, I'm looking to swap a new motor in my 92 325i in the next month or two. OBD I >> OBD II, but I've been reading that M52s can be swapped in with very little work. This is my Daily Driver and I don't want to be stuck with anymore downtime then need be.....

M52s are cheaper and relatively easier to find and with a few light mods are comparable to S50s in terms of power output.

S50B30 would be ideal, but finding one and cost maybe outta reach in favor for the M52.

S54 would be pimp, but a lot of work/cash. Just sitting in one the other day made me

Last option: find another non-vanos unit, swap that in and build the current one for turbo. Lower compression, beefier rods, stronger cylinder walls make it ideal....

Your thoughts............

1-Bar did you do the swap already? If so, what did you end up going with?

Hey Richard....nope haven't done it yet. I have to settle with the insurance. Some dood last week decided it was nice to accelerate from a side road without looking first. Damage not too bad, but needs a new bumper/hood/fender.

I'm going to do an M50 + boost

What options of FI are you looking at?

[qmf]

M50 Spraying 70 > S52 AA S/c from tunerworks @ 6-8psi

[benyl]

S54 w/ HPF turbo kit > ALL

[Bimmer88]

I wish you luck, I hope your not doing this yourself??

Also I would do S54....

"Go big, or go home!" Right?

haha well that's my thoughts. I don't think I could ever fit that engine in my engine bay but you never know... There's I site I used to have that have transplant kits from Germany... but it's more expensive that's for sure.

If I were to go big or go home, I'd stick a N54 in there I'm planning to do this swap with a few friends (hopefully)....haha, shouldn't be too difficlut.

I'm probably going to stick a slug in it for the spring time and hope for the best. My previous car was tubo'ed, love the feeling....so why not again?!? Plus my gf the turbo as well, if you can believe that.....

[Bimmer88]

Well let us know how it goes! I wanna see this once it's done... Damn it'll be a awesome summer project or whenever your wanting to do it.

[1-Bar]

for sure...I'll keep you updated

Uh...yea...thats why the fast ones have S38's turbo'ed........

DOing up a S54 is just a sink hole for your cash
