M50 stroker

[arubaru]

Hello there, first of all i want to say sorry for my english, its not very good hehe.
I got an e30 with a m50b25 NV from an e34 and i want a bit more power, so i was thinking to make a stroke. A friend of mine got a european s50 crank, so to make a 2.9l would i need m50 rods from my engine and m52 pistons and thats all?? What CR would i get? 11.4:1?

I have search info about the stroke but i couldnt find info about if i can use the euro s50 crank...

Thanks in advance!

forget it. euro s50 crank doesn't fit into a M50 block. 45mm diameter vs 51mm diameter

Doesn't the US crank fit?

yes, the US "s50" crank will fit because its really an oversized m50

euro s50s are totaly different (oldscool is referring to the main journal size)

true. euro s50 are totaly different and US s50 crank will fit. so if you want to stroke yor m50 use US m3 parts
