s50b32 swap diffrences????

[jwiles]

as far as performing the swap into 325e with an s50b32(euro motor), is it still the configuration as with the s50b30? where does it (s50b32) differ from the s50b30 set up? I'm specifically talking about the install. Why hasn't anyone made a pretty straight forward build thread on it?

performance wise it seems to be putting up (s54) numbers.

[nando]

not many builds because of the cost/rarity of the motor. these days it makes less sense, as an S54 you can get anywhere and the parts don't have to be special ordered at a great cost (and wait) like the euro motors.

still a good motor though, and maybe a bit more reliable than the S54. do you already have the motor?

[jwiles]

I don't yet, but im seriously thinking about pulling the trigger on that one. Ive gone through all of the the possible swaps price wise. it just seems to have more ups than downs compared to other swaps to get to the hp. plus the intake is all kinds of sexy. the s54 is a sexy beast but the swap is rather intimidating

how ever the parts do worry me a bit, because im not sure where i would have to get them from.

why is it intimidating? it's not really any different than any other 24v swap. the wiring is a little different but it's not that big of a deal.

getting parts is hard because BMW doesn't like selling "euro-only" parts in the US - apparently you need some way to prove you own a euro-market car to order the parts here. there may be ways around it but it's not cheap.

[jwiles]

honestly it is the wiring, and the ele throttle control. something about that swap just makes me really cautious for some reason.

[nando]

the electric throttle is easy. it's just a matter of hooking up the wires (there are only a few).

it would make more sense to figure out the wiring now, than to stick with a motor you can't find parts for in a couple years, no?

[jwiles]

VERY STRONG PT. and honestly it is the motor that deep inside i really want. i was planing on making the s50b32 valve cover look damn close to the s54's.

Having done both, unless your going for a more period correct looking motor go for the s54. The wait, rarity, and cost of the euro only parts can make the euro swap a bear as can finding help servicing/buying the parts for the motor after the fact. The s54 is gaining more aftermarket swap support by the day where as the s50b32 is and always will be a niche swap due to the rarity of the motor stateside.

is it pretty much the same swap as an s50? are their any changes in wiring? what parts are hard to find (obvious ones to replace) and which parts does it have in common with s50 if any?

Do the S54 vs the S50B32. You wont regret it. S50B32 part availability is so annoying its not even funny. Even being a shop ive had trouble with BMW wanting to sell me euro parts.

NO, it is not pretty much the same swap as a US market s50. The US market s50 and s52 motors are not really in the same class as the euro motors or the s54.

If you want a writeup online to walk you most of the way through an inline 6 swap, stick to a US based motor with single vanos. They are FAR more prevalent. The next step in complexity/PITA factor would be the m54, followed by the s54. The euro motors fall in a class by themselves due to the unique issues with parts availability in the US.

Euro s50b32 (321hp)


Euro s50b30 (286hp)


US s50b30 (240hp)


US s54b32 (315-343hp varies based on chassis)



You can read more about them at mregistry.

actually, I think the M54 is more difficult than an S54, because the electronics aren't as easy to deal with. nobody is doing much with MS45..

anyway, I think he was asking if the euro motor was similar to swap as a US motor.

the m54 def looks like a batch and i really haven't seen any decent write ups on it.

yes that was exactly what i was getting at. i was concerned in the overall all aspect of swaps "process/parts" wiring,oil pan,motor mounts, brake relocation, oil pump and dip stick tube. but the biggest gray area is the wiring.

What parts are unique? so i can get them before dropping in? does it share any parts what so ever with any of the US motors? what spare parts would you have laying around in a just in case scenario for this motor? are their any manuals out their for this motor and does it cross on real oem?

[jwiles]

that would be a yes to real oem. @bimmerteck thanks for posting all of the motors
