20b question
I was looking at a 20b online that has a broken rear plate (piece that bolts to trans). Is that rear plate interchangeable with a 13b rear plate? I intend on tearing it down anyway and rebuilding, let me know

the cosmo 13b is identical, but any rear plate will change out.. its just that some plates are thicker than others. if its NA then it wont matter at all, but if its turbo, then go for a REW or RE plate.

you have to machine a couple of tension bolt holes larger also DO NOT forget to countersink them or you will crack the plate when you try to put it together. You also have to drill and tap the bottom of the plate for oil pan bolts, and drill and tap a hole for the 20B engine mount bolt.
20B ports are also bigger, so a lot of grinding is required.
That said, I am running a REW rear iron and am perfectly happy with it.

Just get you a new plate and mount it. Easy peasy and nearly $1k cheaper than buying a normal 20B
