BrokeAzz240sx

i was told by a friend that a RB26DETT would bolt right into one of the Z cars.... i think it was the 280z, i forget which. he said that you wouldnt have to make custom engine mounts or tranny mounts. is this true ?? if it is, how much would restoring (est. $) the car and making the rear end (along w/the rest of the car) able to handle atleast 350 - 450 hp cost ?? Btw, is it worth it, or should i just get a R32 GTR, S13 w/SR or a S14 w/SR ?? what to do what to do?!?!
