M52ti to S50B52 Euro
 

I havent been on here in a while so whats going to on ladies and gents! So I want to swap my M52 with a S50B32 euro engine!!!!!!!!! but the dual Vanos is where im lost, am Im going to need anything special besides the harness? Im going to get a complete engine, 6 speed trans..... do i need EWS from the engine? or anything special?

not worth it IMO. No offense, but if you're asking these kinds of questions, I'm not sure the S50B32 is the right motor for the car.

What are your power goals? 321 hp can be had much easier in a variety of ways much simpler to attain

Thanks for your input, but I'm asking these questions because I have an OBD1 car, I had to change the OBD2 M52 engine to OBD1 which is a single Vanos. the double Vanos is a different animal and the S50B32 is a OBD2 engine. Also IMO the S50B32 is the best inline 6 BMW has made and in the US being rare. I've soured an engine for 1600 bucks with 6 speed trans. So since the S50B32 isn't widely available in the US i haven't had time to play with one nor see a swap for myself. But thanks for your input

Either the engine/tranny are stolen or that guy has no idea what he's selling is. I'm gonna say he knows what he has because you don't just fall into selling an engine and tranny like that. Please check and double check this out before you buy it, because for $1600 for an s50b32 and 6spd, I'm gonna say it probably pooched, cracked block, overheated head something like that, syncro's in the tranny are shot or ground down, maybe the tranny has had overheating issues. Doesn't seem legit, or like I said it's stolen. People don't just sell that stuff cheap. If it's legit good luck with the swap it should be an amazing combo when finished! But don't burn yourself out of $1600, and make sure you know what an s50b32 looks like, he could try and pull a fast one and sell you an m50/m52/s50 non euro, if you don't know the difference.

Euro have ITB hard to miss the engine has high mileage so if I get it I will be dismantling and getting the engine and head resurfaced. Possibly buying titanium valves and string. The only this I don't want to touch is the trans besides changing the fluid to royal purple.

Well to answer your original question, I would get as much as I could from the donor car as possible. That goes for any swap

S54 is a better choice and far more common here in the US. Plus you can easily put the six speed in as well.

I found a S54 E46 M3 6 speed with only 54k miles $1797.09 before shipping to the US. i also found a S54 CSL $2123.84 to many Choices so little time!

I second the S54. Having recently swapped and owned an S54 E30 M3, it's a better choice from a cost vs. benefit perspective IMO.

Wow that's cheap. Where at?

I would like to know where you found these cheap s54 motors with the 6 speed transmissions too for future reference

I have an S50B32 in my 318ti... Best thing I've ever bought... Can't tell you how fast the car is but it sure as hell is worth it.

Any questions I can chime in on?

I own a couple of Euros, and see these more than most. The Euro engines S50B30 or S50B32, are not going to be OBD compliant, in OEM form. They just don't have obd ports - that's a North American protocol, not a ROW one.

I wonder if a US dme can be programmed with s50b32 protocols and still have obd compliance... ?
