@@itsmikelake b20 has 80mm bores and pistons so you will need a machine shop to bore it out. The M50 b20 blocks can be bored to b25 size with no issue and actually they become the same. I do this to get a fresh and perfectly round surface and seen 800hp builds made like this with no issues.
I'm waiting to see how this performs and holds up! I have a '93 525i with 305k miles on the original engine... I would love to stroke it to a 3.0L and swap in a manual and eventually go turbo! These chassis are timeless!

Vinnie Rolla Cheers Vin, it always seems so frighting building an engine but it’s actually not so bad once you actually get into it. I won’t speak too early though, it isn’t running yet 😂
Came across your videos a while back but have just started re watching them again as we are building our own stroker so getting some tips from your videos. We are also doing a vlog on our channel, any advice would be appreciated
Awesome! Cheers for watching. Just make sure you do your research, use good & brand new parts where you can. Rings, ARP studs, Headgasket etc. Torque to spec and you should be sweet!
Hey what's up Mike. Have you had any oil consumption from using the stock m54b30 oil control rings? About to make this build but hesitant just to buy the m54b30 rings for the fame of burning oil
Akbar Elias-Roji this is an m50b25 and I’m putting m54b30 internals into it making it a 3 litre. Its the stroke of the crank and piston that changes the capacity as it’s a much larger stroke.
Wouldn't that give him a ridiculous compression ratio? From what I know M50B25 rods are 5mm longer. Are the N54 pistons shorter to compensate? Edit: I looked it up and M50/M52/M54 rods are exactly the same lenght (135mm) so there is no concern with the CR. M50B25 rod is the strongest stock rod of the M5x family. So, ideally you'd use M50B25 rods (or any M5x aftermarket forged rod), M54B30 crank, and a set of forged M54B30 pistons
Thanks bro! No need to bore the block. As long as the extra capacity comes from the longer stroke of the m54b30 crank, not a. bigger bore size. No need to bore it at all 🤓.
Hi random question, I know you took the block to the shop and they said it was ok, but did you have to re bore your cylinders at all to fit the m54 rotating assembly? Cheers, would love to know, thinking about doing this myself
Risky Bicky hey bro! No need to bore the cylinders to fit the m54 stuff. They go straight in. Just hone the cylinders like I did :). Hell yeah dude do it!!
@@itsmikelake When you going bigger boost you need to make bigger gaps to prevent this gap closing from heat but I think you should be fine with stock sizes for just now.
Dont you need to machine the holes for the m54 pistons to fit? I have that curiosity, i have an m50b25 non vanos stroked to m50b28, i want to make it a 3litre, so just wondering if i need to machine anything or its a straght bolt in to the m50 block
interesting watching you build your m5x's, if there were only even half as much part for those on the west coast, cant get anything here. Have you ever had vanos rattle with yours? and if yes then have you rebuilt one yet?
@@itsmikelake ring end gap for turbo engines needs to be larger than that of stock, or rings will expand and compress into each other. Then they have nowhere to go but bowing out and breaking the ring lands. Really common on e46 turbo builds... Many have learnt the hard way
hey dude i’m from perth, just bought an m50 block with slightly rusted walls, gonna bore it to 85mm and use non vanos rods because they’re stronger than the vanos models’ rods and will handle 15 or so psi easily, which is pretty much my goal. This means that i have to use the 2.5 crank. was really hoping for a 2.8 m50, do you think that i should stay with the NV rods or go b28 rotating assembly? btw love your vids man
Its a rule, there is always surprise liquid. Love engine building and tidying everything up just reading up on how to mix e36 4 cyl manual drivetrain with 6cyl auto drivetrain. Ball hones have balls! I didnt want to pay for one though just a budget straight one for me.

I appreciate your videos. Just in time for m50 build.

I noticed that the M50B25 con rods look a little fatter than the M54B30 ones.... interesting!
Non Vanos M50B25 rods are beefier indeed
Sick, glad you realised iron block is life 😂.. earlier spool, more torque, more power, can't see any cons to going 3.0

I'm still watching your video but make sure you tac weld the oil pump bolt on because they are prone to backing out.

That’s correct. The m54 setup lowers comp to 9.5 which is perfect for turbo
@ 19:00 mark what’s the part number on the rings you used?
Nice job,
if i don't remove trigger wheel from camshaft does it make problem ?
Kamyar yousefi thanks! Yeah it’ll hit stuff in the block if you don’t remove it. It’s super easy to remove!
Awesome tutorial! Im thinking of doing this to one of my e34 m50b25.. But one question have u bored block to 3.0? Stock piston is 84mm

That's awesome man. Did you checked piston ring gaps before you installed them?
Pavel. P thanks bro! The block is a standard size bore and the rings are stock to suit so I don’t think I have to? I could be very wrong haha
@@itsmikelake When you going bigger boost you need to make bigger gaps to prevent this gap closing from heat but I think you should be fine with stock sizes for just now.

You don’t need to bore the block. Only difference between the M50B25 and M54B30 rotating assemblies are the stroke, bore is the same, 84mm.
interesting watching you build your m5x's, if there were only even half as much part for those on the west coast, cant get anything here. Have you ever had vanos rattle with yours? and if yes then have you rebuilt one yet?
How did you align the ring gaps from ring to ring?
Should really have gapped your rings man. Especially for forced induction on m54 pistons, they are prone to ringland failure...
George Hollingsworth really? Shit, I thought because it’s a stock block that hasn’t been bored out, that I didn’t have to? Let’s hope it’s all good!

Did you align the ring gaps as shown?
I didn't gap these rings haha, I never knew I had to. I believe they come pre gapped though.
Are you asking if the rings were clocked?
I thought rings had to be gapped a certain way??
The 50 degrees means turn the torque wrench 50 degrees after the click.
.....I think you should take the t18 as a spare car ;)
Now i want to build one. My m44 is so boring NA
Dalton Phillips turbo the m44 😝
and do you also realize that "standard" rings still need to be gapped to suit your block? first pull on the dyno and you WILL spit a piston/ring/rod

@@aceracing6051 more like that person hasn't got a clue mate . So many wannabe car enthusiasts nowadays .
@@aceracing6051 also why would you bother using 4cyl transmission on a 6cyl engine the gearbox or engine would kill it's self quickly.
Sure, but the 4cyl gearing is often shorter and can be plenty of fun behind the also underpowered 6cyl motor..
