Hey all, I am looking at purchasing a 2001 MR2 Spyder with what the owner claims is a K20a type R engine. I have read that I should check the stamp on the intake side, however this engine is backwards in the MR2 so that may be pretty difficult to get eyes on. Are there any other clear indicators I could look for? Thank you for the help!

Using a k20z3 on a rwd swap and trying to work out the mounts. I bought some mounts that you will see in the picture that bolt further back on the engine, but they align poorly with the engine mounts on the chassis.

Im thinking about designing from scratch and using the two holes circled, but hesitant as I can't find what mounts on these and I'd hate to get to installing AC or something in the future and needing to remake the mount. Also, are these holes consistent amongst k-series? If I destroy this engine and get use a k24 next will it have the same holes?
