I haven't posted anything big in ages...

I believe that this is the next measurement in line after the standard bore size.

Cool, thanks. But that is one of those things where I really don't know what I am doing. How do you choose between regular, 2nd, 3rd or 4th oversize? You don't need to answer that... it is a bit off topic and I could search around for the answer.

bore increase of ten thousands usually bumps up to the next oversize...

Block has been cleaned and honed :)

Going to have them redo the hone because the pistons are 84.480mm.

Stay tuned! Will have some more post worthy updates next weekend :)






Let me know if these images are too large, I'm viewing this shit on a 22" Widescreen so I have no idea!

Mmmmm. Toasty.

What color are you gonna paint the block? Grabber Green? :D

[dude8383]

I think its going to be a traditional silver/grey. The valve cover is going to be black...I like the simple look.

Sir yes sir!!

Man I can only do so much twice a week :(

I'm hoping that I will be ready to swap by the end of April!

[bergie_318is]

sweet project mate

so you sourced a few m52 internals for the m50 block? are these all direct fitment? our were your piston housings to small?

[So Live]

Haha, i know how you feel dude. I get home like every other weekend when school is on. I just got off spring break and was bustin ass hard core style, im thankful i got a week to play with the money pit.

Im excited to see what it makes when your done! Its going to be a pretty stompin little car. :)

Bergie... m50 and m52 have same bore, just the stroke is longer on the m52. They essentially have the same block minus a few obd1/2 specific things afaik.

Turns out theres a whole 2.8 block at my parts place.... youve got me thinking...

Haha indeed...working 5 days a week and going to school part time kicks my ass. My form of relaxation is going to the garage and working on this thing :)


For the post above, So Live pretty much hit the nail on the head.

The M52 has a longer stroke, which should net a few ponies and torque from low-to mid-range.

I'm also going to get some work done to the head...hopefully that will be next week :)

Oh and grab the M52 stuff man, mo powa!!!

[dude8383]

So I picked up my head from the OTHER machine shop!

Had them do a 3 angle valve job and clean it up :)

[CorvallisBMW]

Wow, that thing looks brand new!

[dude8383]

Wow, that thing looks brand new!

I know man...I was shocked too!

I gotta ask him what color he painted it because I want the block in the same exact color!

Oh...and it cost me $250 for the hole deal.

[TwoJ's]

Did they paint the combustion chambers too? For Some reason, the shop that rebuild my cylinder head did, but it burned off pretty damn quickly.

Nice project, looks like fun.
