S50 crank shaft $125

[2.5-12]

TU or NV?

I believe you need 135mm rods to make it a 2.9L

tu....did a quick search and it looks like s50 rods/pistons as well. about to start rebuilding the m50 and would like to do it once and i might go the stroker route...hmmmm decisions

i would love this for my M52 but im going boost so no need for MORE compression! GLWS!!

S50 pistons will require you to bore your block out 2mm, but then you'd have a genuine S50US bottom end, lol.

im interested in this for my m50tu
Im also local so i could pick it up.

Would it work well with these pistons?

what kind of compression would i look at? apparently the pistons keep stock compression, but im not sure how it would work with that crank.

also, i could probably search, but would i need different injectors or software? thanks

or am i going to want to do cams and leave stock crank?

you'll likely need 135mm rods from a M52B28 or S50 to work with those. and the crank

I would imagine the CR would be high 10s low 11s and displacement is 2.9 liters with that crank, TU pistons and 135mm rods from what I gather.

I would get a tune, otherwise swap over to S50 software since thats designed for 3 liters. S50 cams are always a good idea when you bump the CR and displacement.
