6/83 grey market 323i.. mtech I S50 5-lug

[kronus]

Iirc Pete McHenry had a g245 behind a built 3 liter m50 and it lasted for awhile but not for very long of awhile

who's that guy

is he harder on transmissions than i am

[Wh33lhop]

It's a 245 (E21 4 cyl) based trans so it is noticeably weaker than a 260. That being said, one in good condition behind a S52 would probably last fairly long if it wasn't driven by an asshat.

Alpina used the 245 gearbox bolted to a M30 in their E21 B6 and they did ok.

nope, staying white

Color change intended?

rebuttal:



needs the welds ground down and some primer. The rest of the holes still need to be patched, but this was the biggest and scariest rust on the car. I'm happy it's better.

[Farbin Kaiber]

No worries, my transmission is fine, so it's a want right meow.

[kronus]

I dunno guys. We'll see, I guess. I wonder if getting an aluminum M52TU block bored out to S52 specs is practical-ish. Lightness is something I'd like to pursue with this car if I go the S52 route.

Sorry Farbin, I'm pretty easy on transmissions, I think I'll give it a go. Hope the selector shaft isn't too fucked.

Cut down and prepared a replacement. It's getting TIG'd in tomorrow:



I also prepared and cut patches for the rear federalization marker holes, antenna hole, and rear window rail rust hole.

While it's getting inserted I'll need to pull the dash back out to do work on the front window rust. I just put it in, oh well.

Is the dogleg know for being weaker than the getrag 260?

You'll get bored with the s52 in like a week.

Turbo it. The headaches are fun too, you just won't admit it to yourself.

[Farbin Kaiber]

My 323i could use it more, and I bet it wouldn't die before winter. I'd cry if you s52 melted a dogleg.

[kronus]

but that's so sensible and practical :(

I wonder if the small-case m20 dogleg I got with the car would put up with s52 power...

[Farbin Kaiber]

S52, not turbo, not dogleg. Keep it OBDII, and save the diag headaches on a DD.

[kronus]

sidemarkers are getting patched up, don't worry.

finally, progress:




also I've stumbled into an S52 and this car is going to be more of a daily because I bought a crazier one. Which makes more sense: M30 turbo dogleg, or S52 not turbo not dogleg?

[delamaize]

get rid of those damn DOT side markers Please.....
