Thanks for the replies. I was thinking of maybe swapping in an EJ22, but I'd need an adaptor ring. Anyone able to tell me where to pick one up and what the cost is? Thanks.

Hello all, brand new to these forums. I have an 81 Brat with a bit of an engine problem. I was dumb and let a buddy of mine drive it, and he ran it out of oil. Now I need to replace the engine. I'd like to get some more power, but I'm unsure if any other Subaru engines will bolt up to the stock trans. Any info at all would be greatly appreciated. Thanks!
