Imo for what its worth get a low klr AU engine..
Especially with accessaries serpintine belt etc...
Older m/p manifold will fit, just run two head gasgets or leave it and tune...

Yep different stroke/bore.. one of the two.

I'd steer clear of the ea engine if I was buying one, but you may or may not be able to make a usable engine out of the ea donk.

btw, chris (madeaspack) sold you an exhaust manifold that you were gona do up for turbo.. any progress ?? (i'm doing the same, needa know where to get suitable mandrel bends ;))
