A few 1jz and 7mgte crossover q's

As far as clutches, is it true that a clutch kit for a 7mgte will fit on a stock 1jzgte flywheel? and that a 2jzgte kit will work on the 1jz but would need the 2jz flywheel??

Any suggestions for a good clutch kit if i'm aiming for about 350hp?

As far as radiators, would a mkIV turbo aluminum radiator fit into an '88 mkIII?? I'm looking for one in the $2-300 range.

oh and any suggestions on a 1jz mkIII intercooler kit? or just go custom?

thanks for the help, i've almost got all the puzzle pieces together.
