So I have seen some discussion on this but not a clear answer that I could find. Have a 94, the engine is worn out (300,000+ miles), and trying to figure out what to do. Was thinking of just rebuilding the engine and adding a supercharger. Well, can't find a supercharger for a 94 engine (i assume it's because of the fuel system, not the mechanical aspects). It seems the 94 being pre-OBDII will have a difficult time adjusting to the extra fuel needed with the supercharger. So then I started thinking about upgrading to a 96-97 engine, converting to OBDII, and adding the supercharger but that adds its own problems. Some seem to say the trans will work out of my 94 (A442F) some say it won't, from what I can tell only the 95 engine has the possibility of working with my trans but that is if it is an OBDI engine which wouldn't help my issue. Not that big of an issue, willing to replace the trans, doubt the old one would handle a new engine, especially with a supercharger. Now I am in an engine, trans, and now the wiring harness and ECM would need to be replaced. All of this to get a 300 HP engine (maybe). So then I started reading about diesel swaps, V8's (Toyota or LS). Now I am just trying to figure out the bang for the buck kind of thing. I am a good wrench, have access to practically any tool needed, including a lift, and a mill. Just not sure I guess. The 96-97 OBDII conversion with the supercharger seems the simplest, same mounts, no real custom fabrication, and gets some decent power. NOT WORRIED ABOUT FUEL ECONOMY AT ALL. But then if I have to replace all of this should I just go big or go home? If I am missing something in the 96-97 engine swap let me know, (i have the ability to program modules also, but just the factory software with a pass-thru device). Sorry if this is just talking about things already done but I couldn't really find a clear answer searching the forum.
