Having gone through a few too many engines it would be nice to see you put up a video on how and why these engines give up. I have a low mileage (50K) 97 S52 M3 and am not sure whether I might be better off buying an old M50 block and having it machined and built rather than trusting the current engine (and I might be better off keeping the original engine in stock shape). Thoughts?
Apparently the m54b30 rods are the same as the n54b30 rods which can hold 600hp ish. idk what the non vanos m50 rods can handle but I'd wager they are similar. source: I saw it in a forum lmao
Running on E or 93? I don't know how much boost you were making but I've heard 93 on stock compression can be pretty risky over like 10psi. Following the build.
@@joshuadunand I find that as long as I stay off the throttle coming in and out of the my suburb and stay far away from Cruise Night I don't get any trouble (so far). Being old helps a bit. I've got the VF Engineering Supercharger on mine right now and would love to trade up to a build similar to yours. 500'ish is usually about the limit of streetable with this platform. After that the big turbo and the heavy clutch start to make it less fun as a grocery getter. I'm going to go into your back articles and try to pick up what you learned going through so many engines.
Get a thicker head gasket cometic 1.40 and replace the head gasket with cut ring your gonna maybe need to resurface head now don’t cut corners or you will regret it.
No it was just a JE cutring. 0.068" I believe. Spacer would have been ideal but at the time this motor was built everything was backordered 8 weeks plus.
@@joshuadunand expierencing the same thing! currently turboing my m50, and having some trouble sourcing a spacer. so im not sure if its safe to run a je cutring up to 12psi without a spacer
