:d
clutch wise you'd need the small block flywheel a small block c16 friction plate but with f20 splines... i would assume!
splines are different between the f20 and f28
why not fit an f23 from the astra gsi turbos? 5 speed lighter than the f28 but will cope with anything your 1600 will ever throw at it can be bought for 80-100
