If anyone would be able to tell me what harness or wiring problems I would run into by just switching out my obd1 LS block and head to a 91 b18A block and head?? By the time I am done building my block which all I need is lower comp. pistons and a turbo kit. The only other mod in the bay will be a skunk IM. So if this is worth all the trouble I might be putting myself into please let me know before I do anything I shouldnt. I just cant seem to find anyone else doing somthing similar into a 3rd gen teg. Any opinions are appreciated. thanks
