87 vfr700 F2 Brake system

I plan to do the f2 conversion and i am looking for a nice braking system. i read on here that with the f2 conversion i can possibly use 90-93 vfr calipers. Since i am having a hard time finding some calipers to run with galfer rotors and pads. i wanted to see if it was indeed possible to run the 90-93 vfr calipers. my forks or 91 cbr forks that i plan to run racetech gold valve emulators on...so can anyone confirm or suggests some break calipers for both front and back f2 wheels?

 

After seeing the thread Heavy modifide(sic) 86/87/VRF, from japan on this very board, I decided I was going to try to put on some Nissin 4 or 6 piston calipers. I've already done the F2 conversion, so this should be relevant to your interests. Accepting donations if you want me to get the calipers and check fit sooner

 

damn you stole my idea, any idea where to get the nissin 4-6 pistons from.
