1992 Civic VX, doing I/H/E to it atm, but also considering mini-me d16Z6 head swap. Should i be worried about ECU right now? Also what ECU should i look for if i do the head swap? I'm just having problems finding info that covers the d15z1 engine, seems most mini-me's are just done from non-vtec ready setups. Plus the efficiency wiring is throwing me off some.

 

You shouldn't worry about the ECU until you do the head swap. A recommended ecu is the world famous p28 ecu.

 

its very eas just get the whole head assembly with intake + extras, for timing belt use your VX belt. it will work like a charm.
actually a VX block + d16z6 = a JDM D15b sohc vtec (130ps=128hp) out of a 1.5l

vx rods and pistons are much different from any other 1.5l
