I'm going to get it bored to clean up the cylinders, new piston rings, rod bearings, crank bearings, etc. All new gaskets, new timing chains. Plus all the little nick-nacks to get everything back up to specs.
Getting head studs and thicker gaskets as well.

The BIG question is. Should I go with a ProCharger or a Turbo on the motor?

So what do you guys think and why?

Feel free to ask any questions if you need any more Info about the build.

Please keep in mind the early 92 M50B25 does NOT have knock sensors. Get yourself a 3281 -5281 engine 1996-1999 Years, convert it over to OBD 1 93-85 Harness (325 or M3) ECU completed set up.

I would def do a turbo kit hands down.

Hope this helps, best of luck.
