m90 supercharger question
 

My friend has a m90 supercharger off a thunderbird that he has had laying around for a while. He decided he wasn't going to use it and said he would give it to me if i could use it. I'm pretty sure it isn't a bolt up for the 99-04's so what would I need to get to make it work?

You are going to have to be a little more specific about the t-bird. Year? Engine?

early 90's, 3.8L.

I asssume that i would have to switch back to the old heads and basically lose all the horsepower that i would be gaining by the SC. I just wanted to make sure

It's a single port, so you'd need the pre '99 lower intake, pretty sure you can use your stock heads. If you have all the hoses and stuff your pretty close. Looks over a 3.8mustang.com for some more info.
