There is a 92 IROC Daytona for sale in my area, It has a 3.0 v6 & a auto trans. I had a idea of swapping in a TIII engine & trans for a poor man's IROC R/T. Would it easier to find a 4 cyl harness or will the spirit R/T harness fit the Daytona. How about re pinning the v6 harness to mimic a TIII Daytona harness & sending the computer in to Cindy to re cal..? Any thoughts?
