any link for where you would get one of these

Even if you do, you'll probably spend more time with hood open than in the seat enjoying it ;)

Yeah m52b28, out of the 328i e36. I thought they were very reliable with the alusil block. I know making manifolds and downpipes are a balls for them and not many people would be willing to do that. But I've not read a bad report from anyone who has had the job done.

Well, I've done my homework before I bought s50b32 for my own conversion and from dozens turbo'd bmw's on other forum I couldn't find many m52 engines. Actually last project which I've viewed was e36 328 and owner replaced m52b28 engine with older and much more reliable m50b25 unit before installing td04 - 13t .
You'll need much more time and work to prepare m52b28 engine for turbo than m50 unit.
They are good for supercharger but not for turbo.
If you have some free time, use google translate and check the turbobmw.pl gallery:
http://turbobmw.pl/viewforum.php?f=3
There's plenty (+100) turbo'd bmw engines in there, some are +700 hp. Street cars, drift cars and dragsters. It took me whole weekend to read just part of that forum, but at least it helped me which my choice. I spoke with few owners from this forum and all of them have told me same thing:
"if you need reliable unit and you're not mechanic yourself choose N/A conversion or supercharger"

what clutch, flywheel, starter do you use with this?

is this what you have in your own car?

thanks for the replys im very interested in this

do you need a sleve for the shaft ? or how is the adapter plate spacing accounted for?

No, I've sold my v8 and now I'm doing s50b32 conversion. I don't know what to use. Seller is saying that best way is to use half of m50b25 flywhell, m50b25 pressure plate and m30 clutch disc. Afaik some people were using standard m50b25 clutch kit with dual mass. I've send a question to the seller, we will see what he'll say.

yes, you may be able to pick up an S50 for that money but S50 only makes 280-340bhp without spending mad money and that's with a good set of exhaust manifolds if fitting it into a RHD E30, fuck those up and you might only have a little bit more poke than a decent M52b28 while an M50 with a turbo is good for 400+. There's even a good few Scandinavian lads even selling S50s to find M50 turbo builds as they want a cheap way to 600-800bhp. I know they do it because S50s are worth two or three times what they are worth here but you can barely get somebody to map an S50 with a set of cams here while most decent tuners should be able to manage a non-vanos M50 and a turbo.

Then of course if the M50 turbo engine does shit itself, it's just a case of buying another 2-300 euro M50 engine and bolting all the bits on.

Stroked M50s are great but it's defeating the purpose of the M50 being nice cheap power with engines being plentiful if it goes bang in my opinion.

If all you want is 200-250bhp in an E30 though an M52b28 with cams, M50 inlet and few bits is very hard to beat given then engine weighs about the same as a 318is engine though and with just those few bits the engines are very reliable if you start with a good one.
Manifolds are handy enough too, compared to the S50 ones anyway. Did first one three years ago and now has M50 inlet, bbtb, re-map and S52 cams and it pulls very well.
He was thinking of a supercharger but reckons its enough as is since its just a Motorsport cab and a road car.

For Irish tracks, the 4L V8 is still probably the best option though for value. Even if you did go for mad power with a turbo M50, the car might not be any better competitively due to the E30 having a shit back axle for traction. You'll make loads of smoke and go sideways alright but could be a snappy prick of a thing especially coupled with some turbo lag and probably will be difficult to keep up with other cars.

Rear axle can be improved with abit of work but if your going that far, probably wouldn't be here deciding between M30s and M50s :D

That adapter plate looks like a good piece of kit. Much handier for gearboxes anyway especially if its a drift car as even the V8 5 speeds or E39 M5/E46 M3 6 speed box will eventually start to act up and your out of pocket again.

If it was a road car, easy choice would be the 6 speed box as it can make the car so much faster with a good choice of gearing.

you really seem yo know your stuff when it comes to bmws

ive seen a few of your builds over on bmw driver (not a member just creapin) :)

ive a few questions for ya

i bought a e36 328i this year to do a few track days in,and cought the bug

i want to get a bit more serious next year tho, was looking to get a cage fitted etc but my car is stink red rotten with rust and wouldnt justify the expense

so my attention turned to buying an m3, but there is nothing out there for reasonable money

this leads to my first question, is there a reason why all the pro m3s in ireland are s50b30's and not s50b32's is the latter less reliable or whats the reason?

i would love to do the v8 conversion but the more i look into it the less atainable it seems

so im back to my 328 single vanos

and the questions start

where did you get your ecu remaped?

what does the bbtb come of? or is it am

will ebay manifolds do the job?

s52 cams where does a man get these?

what power can i expect with all this done?

also what ratio diff would you recommend in 1 for drifting ( it has a 318i diff atm)

sorry for plaguein you with questions but i cant make a decision on what to do

If it's so easy to manage m50 turbo, and so many people can do it, why I never heard of any around here? Can you show me some links or videos of properly running irish build m50 turbo with some dyno charts? I'm not acting smart Dave and I'm not being offensive, but IMO opinion it's way to much hassle. You are not going to tell me that those turbo'd engines are easy to maintain like N/A engines (especially if it must be cheap cause OP doesn't want to spend crazy money on his project).
After going through all costs with people who building them, it was cheaper for me to buy complete rusty m3 evo, all service parts, clean rust free and road legal e36, suspension, bucket seats, harnesses, wheels and half cage and I still have some funds left. All at cost of turbo'd m50 engine only.You can do that cheaper for sure but how long this engine will work?
