I'm just trying to keep my Mustang going. Drove it 1200km on the highway for a family trip and now I have low compression on 1 and 4 (100ish) and very low on 2 and 3 (50-60). Cheapest engines I can find are out of a '93 Mustang and a '93 Ranger. Both are 2.3Ls, but with the dual plug. Is it as simple as pull out and put in with minor computer wiring, or do I need different mounts and major wiring? If it's easy I'll do it, if not I'll get my hands on a 2.3 Turbo, just trying to take the easy way out for now.
