Hi I have a question to ask you guys Does the supercharger that came whit the thunterbird sc would fit the mustang 3.8 And if it does will it require to many mods to make it work
yes it fits, but the SC engine did have mods that accompanied that SC, it isn't necesarily a bolt on afair.
http://www.3.8mustang.com/forum/showthread.php?t=142607 has alot of information about the M90 setup. http://www.v6power.net/forum/viewtopic.php?t=10857 a very detailed howto get the M90 on there. Being a 1996 Mustang I assume from the username, it would be more bolt on than a 99-04 and more than the 98 too, but it still requires some work.
