I wanted to add a how to 4.2 v6 swap and split port swap. Here is a quick basic guide. This guide is similar to the one I followed. It is from another forum, click here. Even though the guide is fairly complete, I'd like to add a few things; 1.You do NOT need a 01-up 3.8 oil pan for the swap. You can use an earlier oilpan and simply cut off 2 studs (this does not cause any problems or weaken anything.) I made a how to below 2. You will need to do some custom work to the heating tubing. 3. You will need to do some custom work for the fuel rail. 4. You need to hold open the IMRC or remove and plug the holes. I removed the IMRC and plugged the holes. 5. There is an extra temperature sensor the Mustang uses. You will simply need to drill and tap a hole for the extra sensor in the intake. 6. 94/95 or 94-98 (can't remember which) the stock mustang headers are the best (obviously long tubes would be better) 7. Use as much of the Mustang 3.8 parts as you can. Maf, injectors,upper intake(or windstar conversion)... 8. You can try to get away without a tune. Its recommend you do get it tuned though. 9. Emission controls are an issue (EGR). If you don't have to do emission tests, I recommend just removing all of it. 10. Play will connectors and sensors (again, use as much mustang as possible) 11. K member. (side note) The v8 and the v6 members are the same for the same year. But you need the correct motor mounts. If you have 94/95 k member use the 94/95 v6 mounts, if you have 96/97/98 k member use the 96/97/98 v6 mounts and so on. I think that's basically all. I'll update if anyone has corrections or if anything else comes to mind! Happy v6ing!
