Cheap S50 would be M50 engine with M54B30 rotating assembly plus S50/S52 camshafts and you got yourself a 3.0L beast. All parts fit just fine, no machining required.
Here is my video explaining the details:

So is he engine in a chassis and running? This shit looks pretty epic man, thumbs up
install that baby and dyno that monster.... great work...you should start thinking about building some and sell them...heck, if it makes more power than s50/52, i'll pay 2k for it...

Great build...and ballsy for reusing rings, bearings and even seals . Out of curiousity when you sand the block deck with sandpaper and water, were you not afraid of the immediate occuring of rust? water into cylinder walls?

FYI, you are correct OP
M54B30 crank = S52 crank (forged)
notice I underlined the B30 part...other M54 have a different crank
good work
also, at 10.5:1 CR, 87 will work fine with no detonation..........VR6 engines have seen over 300k miles on 87oct at 10.5:1 stock compression ration

nice writeup.. im gunna think about it... what kind of power u making now
So you put m54 pistons in an m50 block?? Which crankshaft did you use? Why didn't you just use the m54 block?
I didn't even know this could be done. This is sick..
Oh my god... If I had the money and skills to do this, I would. Interesting DIY, must keep this in mind.
How much was the block? I can't find one for less than $1000.00
any different in terms of performance if using S50b30 86mm inner assembly compare to M54B30 84mm?
Could this also be done with an M52B25 or M52B28 block?
Hey, I've been reading about m50 strokers for quite a few months now. Compared with the lack of information about m50 strokers out there, I really respect this project (especially for being on a budget like this). Really, really awesome work man, thanks for sharing it.
can this be done to NV motors?
I think the M52B28 has a wider bore, but as far as I know the M52B25 is exactly the same bore and stroke so it should work.
Edit: Just looked it up, M52B28 has same bore but longer stroke than M50B25/ M52B25, so this should work for all of them.
Okay, new question, does an M52TUB25 head fit on an M50TUB25 block?. I'm wondering if it is possible to do make a 3.0 stroker with dual Vanos, but keep that good old bullet/ turbo proof iron block.

Wow, glad i caught this, very simple and cheap.
