Hello, I'm just looking for some insight into making the "G23". I heard about this swap today and it interests me to say the least. If I purchased an H22 head and put it on my F23 block, what would I need to do in order to pull off the job correctly? I fear that where my F23 is a SOHC vtec and the H22 is a DOHC vtec, I may have to screw around with the computer. If I do indeed have to screw around with computers I may not proceed with the swap. I guess it all depends on the complexity of the computer mod. Can anyone provide the insight I need? I sure appreciate it!
