Any ZL (1.5l) botom end parts will work with the 1.6l (ZM-DE) engine. The ZL-VE head (which has S-VT) is a direct swap to the ZM-DE engine. You will need to figure out a way to control the hydraulic controller that varies the intake cam timing. This system is similar to the one used in the 2001+ Miata BP-VE engines, so talk to the Miata guys about it the S-VT on their cars to learn more.
Any ZL-DE top end parts will work with the ZM-DE engine.
European spec ZM-DE 9.4:1 pistons are also available:
ZMY1-11-SA0A normal size
ZMY1-11-SB0A .025 oversize

Any FP and FS engine parts are interchangable.
