Time to refresh and upgrade the M20. Looking for feedback on both.

Thanks for the feedback. This might be a dumb question but if you remove all of the nuts from the block where I am pointing here what is holding the motor in place? Would it just be resting directly on the sub frame?

Looks like this guy was causing the trans to hang. Surprised more people don’t mention removing - seems like an easy win.

What part is that? I've pulled a part quite a few e30s and don't recognise it?

Its the rubber buffer on the bottom of the motor that appears to stop the motor from contacting the x member. It has a replaceable rubber pad.

Hmm, mine didn't have that piece.

Im 8/88 build date - maybe it was added ?

Usually just missing, or a PO didn't reinstall it.

Gonna get my neighbor over and see if we cant yank this motor n trans tonite. Any special prep needed to lay it down or does it sit on the oilpan/tranny okay - just long enough for me to separate and mount the block to a stand

Nice work!

Has anyone succeeded in applying a paint or any other treatment to the cast manifolds that actually lasts? I tried POR high temperature on my alfa and I can see it flaking very quickly. I don’t want to spend on a jet hot or other outsourced coating. I have a blast cabinet and can prep them but dont want to make the fairly large effort if its all gonna flake...

I've been curious about the graphite spray technique for a while - I'll give it a shot here. If anyone has used a particular product or has feedback lemme know!

I have had luck sand blasting the manifolds and spraying them with rattle can header paint with ceramic from the parts store. Just make sure the first time they get hot, they are clean or the oily fingerprints will burn in them (I use the silver).
