can but you have to do some adjustment.
You have to make sure the piston valve pocket able to clear the exhaust valve if you decide to use 16V piston. Anyway it's not advisable to use 1st generation piston since the CR is low.

What is ur original wiring and ECU? You have to consider on the wiring and ECU too.
