I have a 3.8L 95 T-bird supercharger that i want to install but...:disgust:the bolt pattern is different from the supercharger to the top block. I need a spacer that has both patterns. Supercharger & top block. I believe its called the upper intake plenum. Do they make that or do i have to go back to shop class and make it myself!? I dont have enough $ to buy a new kit($3,200) but i got all the parts for that and ive heard its a pretty popular route. My brother in-law is going to make his turbo and he would like some tips as well. BTW I own a 04 3.8L and he owns a 02 3.8L. My e-mail is MistaG84@yahoo.com Thanks for whatever info. i get :good:
