Pretty much everything is exactly the same across non VVT M13, M15 and M16. SO many of the parts I've recently purchased all list "M13 M15 and M16" in the application guides. From doing a bunch of reading, The blocks and heads are all pretty much the same shape across the three with possibly some minor inlet/exhaust port size difference and some valve stem size differences. All three blocks use exactly the same bore size, same crank and rear main size, same head bolts, same gasket kits, etc. Use the Partsouq.com website and punch in your VIN, get some genuine part numbers from the factory diagrams there and then do some googling for the application.
