m50b25 block question

Post Sat Jul 23, 2011 8:07 am

I bought m50b25 engine and m54b30 pistons for stroke.
Block checking shows that it was honed to second repair (D=84.5mm).
What do you advice: installing block sleeve or changing block?
thnx.

Fitting those pistons to your engine will lower compression, if you are planning an engine build then you want a standard spec block

yes, but motorist advices to install cast-iron sleeve and hone them to piston size.
Also whatever another used block has own working defect.
