ok, i came across a guy that has a Ford M112 blower for sale at a good price, knowing this was on a lightning i knew it wouldent just bolt on my 2000 mustang gt, I asked what would I need to do to make it work, he said " all you need to do is find a intercooler that fits the 4.6l 2v engine and sit the blower on top. Sounds to me like it would take alot more then that, my question is , would that really be it and if so would what i have to do if its possible?
If it came from a 5.4 Lightning it wont fit the heads are spaced father apart that the 4.6L. The best thing your you to do is buy a Paxton, Vortech, Procharger blower. It would be the best choice if u want a roots type go for Kenne Bell. But judging from your question u want cheap. Spend the money on a proper kit.
I am not sure on the 03/04 Cobra blower would work on a 4.L SOHC my guess is no.
I dont think it would be as easy as your friend is telling you. The lightning engine is a 5.4L 4 valve per cylinder dohc engine while yours is a 4.6L 2 valve per cylinder engine. Find a modification shop around where you live that specializes in mustangs and ask them. The best way to find a good shop is to join a online mustang club in your area and ask them where they take their mustangs.
Your best bet is to spend the money for a blower that was specifically designed for your car. Less hassle and less problems (you don't want to blow your motor up). The R&D has already been done...so why not utilize it???
