Pulled the m20 tonight and ... dammit

[bimmer630]

Found the passenger side motor mount ear broken clean off the subframe AND the drivers side transmission mount ear snapped off the tranny (the tranny I just bought)

I guess with the mount sheared off, the engine tilted and my through bolted UUC trans mounts didnt "give" enough and broke the trans itself from the "twist"


Also explains why my fan kept kissing the lower passenger side of my radiator. wish i found this sooner.. shoot. time to weld in reinforcements on my spare subframe.. and hopefully TIG weld this trans back together

pics to come

Thats why the pro3 race car guys use stock mounts on the trans. Shitty deal dude. Get to work!

Sounds like it could have ended a lot worse than it did!! :shock:

On the plus side it was really nice to be able to just yank the engine and harness all together after pulling the dme harness through the firewall.. took only a couple hrs to pull

Who?

Pro3, west coast e30 racing. A lot of them will use stock rubber trans mounts so if in an accident the mount breaks instead of trans.

So one team runs them... You are saying that they would rather be more prone to miss shifting and destroying rockers and the engine then to have to spend $20 to weld the mounts back on the transmission if they get into a bad accident that. That's retarded and a lot of teams run solid mounts without breaking the transmission, probably more then those running stock mounts.

i too would say more people use solid and stock rubber, but i really wouldnt know. just makes more sense to me

PRO3 Racing is in the Pacific Northwest (Oregon/Washington) and is almost the same as Spec E30 with slightly modified rules.

If your engine mounts are solid and your trans mounts are rubber does not mean your going to mis-shift. Think about it. The engine is not moving and since the transmission is also not moving since its bolted solid to a unmovable engine, the trans will also not be moving.

Yeah with solid motor mounts it wouldn't move but if they are using stock mounts or Ireland Engineering mounts that are going to fail in a short time then the solid mounts would help keep everything from moving.

We are just starting to learn the TIG welder at the shop.. I havent even touched it myself but The guy I work with is getting good at it and were gonna take a shot at welding that thing back on.. Hes only so far messed with stainless ..

Any tips for getting a successful weld?

true! Unfortunate but you lucked out. What kind of TIG machine are you using? Just learned myself and really looking forward to fabing some stuff.

[328ijunkie]

replace that subframe please.

[Exodus_2pt0]

replace that subframe please.

Why? A properly repaired sub frame with a good weld will be stronger.
