hey guys, so i got this 1990 trooper with the 4ze1 engine in it. it had a bad casting number 2 head in it. so i bought a new head from j and c heads, it has a 1 year warranty. so on so fourth. so my question is. can i run this engine without all the smog on it? will it run the same or run crappy? i live in oregon. so no smog regulations to worry about. i know my old 2.3 carbed engine didnt have any of the smog on it and it ran great. but it was also carby fed. so i want to get rid of all the smog junk. but im afraid ill get crapy results since its efi and has a oxygen senser and what not. anybody already done this? know the side effects and tricks? please let me know.
