Noob with a couple of questions
 

Greetings! I just bought a 92 civic cx and I want to put in a vx engine. I did a couple of searches but there seems to be different opinions on exactly what I need. I know I need a motor and computer(ecu?) I think I need an o2 sensor. I think the wiring harness is the same bc I heard the 92 was pre wired for vtec? what else? Egr? Also where is the best/cheapest places to get these parts? Thanx in advance!

Hello sir, different car, but check this out: crxMPG - Gas mileage never looked so good » CRX D15Z1 (Civic VX) Fuel Economy Swap Guide

I read the guide but its like stereo instructions. I guess I need to know if my 92 cx wiring harness works with the vtec e engine. And I do I need or not a new 02 sensor? fuel line? egr? This is all confusing for me:confused:
