Ive been researching for a teardown and rebuliding of my MT 1.5L ZY-FE. It seems there still isnt much in the way of aftermarket parts for camshafts, pistons, crankshafts, etc.

Also, could it handle parts from different engines like Subaru or Toyota or Ford? They seem to have more R&D for inline-4's (H4 in the case of Subaru).

Thanks for any help yall can provide.
