A 4-piston swap from another FC might be cheaper, but i'm sure you thought of that already.

 

Aaroncake Has A Write Up Kinda In His Update Of His 7 . He Used The Stock 4pot Off The Five Lug . I'm Going This Route Since Theres A Few 7's Around The Yards Again

 

what brakes do 87 turbo II's come with?

 

I did a little searching but didn't find any big brake kits from Project Mu for the FC. For the FD yes, but not the FC.

Rishie @ AutoRnD can get you Endless brake kits.
