just recently bought a 90 civic hatch si, and i looked at the engine stamp today, and it says ZC! but its a single cam ZC. what are the specs on this engine? would all d16a6 engine parts fit this car? i wonder if this engine is as powerful as the d16a6. do the d-series trannies bolt up no problem?

off topic, but it struggles at low rpms. when im starting in second at like <10 mph, i will sit there and floor it for like 5 seconds before it starts picking up. what could it be? maybe just needs a tuneup?

 

sohc ZC was rated at 120 PS...which means around 118 hp.

 

they are 1.6Liter SOHC engine with 120 ps like someone else said
they are basically the same as the D16A6 just with a better cma i beleive

if u floor it in 2nd almost on 5-10 mph u are going to stay there
HOnda motors are tqless u should know we dont haul before 3 k rpms
