Hello,
There some part for N/A tunning for the 1.6l
The ZL-VE head with Sequential Valve Timing
Here from the protege faq the head sould fit:
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.

also the after market piston from B6 miata engin should fit.
Because B6 and ZM-DE have the same bore and stroke : 78 /83.6
you can found here the info:

at the bottom of the page
or here:

11:1 compression toda racing piston or wisco piston for b6 11.1 compression but 80mm bore vs 81 mm for toda
The piston look like have same size of connecting rod pin
according to this site :
http://www.rpmrons.com/MazdaRods.html
Because the part number for the B6 SOHC connecting rod are: CRMA9
the connecting rod part number for ZM- De are: CRMA9
And connecting rod part number for miata b6 are: RMA13
you can't swap internal part from b6 SOHC to a do DOHC
Basicly CRMA13 and CRMA9 are Interchangeable part.
The piston from toda racing are over sise 81mm vs 78mm for stock. The ZM-DE(1.6)
There the information about the ZM-DE and B6 share some part
The 'Z' engines are a new family which is an evoltion of the 'B' engine. The head is entirely different with round ports and narrow valve angles but the shortblock is nearly the same as the B6.

The intake manifold on 1.6 found in europe have dual runner.
There for more info on protege faq

Your get more power because with after market piston from B6 have more bore 81 mm that meen bigger volume for the combustion chamber. Also Sequential Valve Timing and dual runner intake manifold. Of course you need the ZL-DE ecu or mesquite or other stand alone ecu for control the Sequential Valve Timing.
With all those part I tink you will achive your goal.
