b20/vtec help

ok i want to install a b20vtec into my 91 crx and i have a few questions im confused about... ok do aftermarket companies make hc pistons, rods, ect... especially for this swap or do i have to use the b20z pistons, cause i do know that the other b-series pistons wont fit. Also i know that the sleeves are weak so if i get the block re-sleeved will that make this motor reliable? and if i have lc pistons with new rods and sleeves, will it make this motor eligible for turbo with small amounts of boost? and what would the safe redline be for the motor? i have heard if its rev'd up more then 8400 it could be catastraphic. any help i could really use thanks
