Anyone with a 1992-95 DX Hatch with a B20z2 (came out of a CRV) put AC in the car. What can I use from the EG and what can I use from the CRV, I can find these things everywhere at the junkyards.

I would love some insight from your smart Honda folks if you are willing!

 

You can use everything from the Civic AND the original CRV A/C bracket if your engine came with one... if not, you can find either a P30 (Del Sol DOHC VTEC) or P7J (CRV) A/C bracket and tensioner and bolt your Civic A/C compressor to it.

 

Very helpful, thank you! Would you know if the wiring harness + the ECU would of been swapped as well if they put the B20z2 in the car?

If so would this effect anything with the AC install?

 

Neither the engine harness nor the ECU from the CRV can be used in the '92 Civic chassis. If I was doing your swap, I would use the engine harness and fuel injectors from your original engine. Modify the wiring harness as needed to reach all of the common sensors, source a '94-95 Integra LS/RS/GS distributor and manual ECU, modify the ECU to accept a Hondata S300, and have the engine professionally tuned. Others here may jump in and bash the S300 system as a bad choice... and suggest another engine management solution like a Link ECU or other stand alone box... the important part to understand here is that no factory ECU works ideally with your combination, so a tunable solution is necessary.
