Installing a d15z engine
 

Some people say it's going to be diffilcult to put a d15z (VX ENGINE) into a non-VX civic car, is this true? Please give me your full opinion, because I'm going to purchase a d15z engine/trans/ecu and build a VX, because nobody out there is willing to sell one. Thank you.

2 things to worry about. wiring for the 5 wire o2 sensor and vtec. you might have to worry about egr valves and things like that too.

my full opinion depends completely on your experience with swapping motors.

the other thing to consider if you are putting it in an obd1 car (92-95), since VXs are OBD1, it is much easier to install in a civc that is also obd1
