My current 4 dr dx has AC and i do not want to remove the AC when doing the swap is that possible?

 

Absolutely, it just may make the swap a hair more time-consuming. All of your stock components will bolt up just fine to the DOHC ZC.

To keep the A/C in while doing the swap (without discharging/recharging), you'll have to unbolt the compressor from the motor and use wires to tie it out of the way.

If you're going to run an aftermarket header, you may have to get a slim fan to replace your stock A/C fan.

Hope that helps.
