Is it possible to swap out a 1995 3.8 with possible blown head gasket/seized, for a 2001 mustang 3.8? Will it bolt up to the 4R70W, and would it be all that much trouble to convert it over? please help, any response would be much appreciated.
sorry for sorta hijacking the topic, but would it be possible to just add the splitport heads, and upper/lower intake to the 96/97 block? then add the windstar fuel rails? I doubt its that simple, but I thought I'd ask
Have you looked at the article that PJ wrote up about the 4.2L install? 4.2L article
Most of that applies to a splitport 3.8L install as well.
If you have specific questions on the install, I'll do my best to answer them for you, but I don't have the time right now to write up an article on it. Besides, there are quite a few different ways to go about the install (DIS or distributor, EGR or delete EGR, IMRC's or no IMRC's, etc...).
Just curious Rod, which way did you go with yours with regards to EGR/IMRC?
I am running EGR, using a custommade EGR tube and DIS ignition (which was a pain to wire up). I have a 2000 engine, so mine doesn't have the IMRC's. However, on my DOHC 90 XR7, I used a MSD tach driver and a MSD RPM switch to control the IMRC's.
If anyone needs a wiring diagram for installing DIS ignition on their 94-95 3.8L MN12, just say so. I think I still have a copy of the diagram that I made up for Thomas awhile back.
