Ok well heres the deal...i have a 95 civic cx with a weak d15 but i just got a free d15 Vtec-e motor and a ZC motor which i planning a mini me because the block is blown...of course the SI motor is stonger but is there any parts i should use over others...such as Cams and what not??? or should i just run the ZC straight on it and just scrap the Vtec-e??? Also does anyone know if the D series Valve Covers are interchangable between vtec models...such as vtec-e on the ZC??? THANKS

 

Unless you are trying to save gas, just swap the ZC motor in and be done with it.
