White Bunny Clutch Question

[spg240sx]

Okay, I've read up on quite a bit of material from several different forums involving the white bunny clutch setup. I know the original is a D21 flywheel and clutch. However, several variations have been found to work and I have a few questions about them. I just finished my KA-T T25 setup, running 7lbs. OEM clutch obviously will not hold once I am in full boost. There have been rumors of people running the D21 flywheel with either a 280zx turbo or 300zx clutch and pressure plate and being able to hold 400tq. The thing I can't quite seem to find is if these people are using OEM replacement clutches for those models or if they are using a stage 1, 2 etc.... Can anyone advise me on a white bunny setup that would work if my top HP range is 300 ( Bigger turbo in the future etc) ?

(YES, I have searched, but have found nothing definitive.)
