its pretty simple over here in australia every one puts Rb20's RB25's RB26's into S13/S14/S15

if u use the skyline cross member the motor will bolt str8 in and the great thing about this is the cross meber bolts str8 on so once u have done that all u need to do is drop the motor in ur going to need a RB25 gearbox and Tail shaft as wellbut going to need to modify the tail shaft then get it balanced B4 u can fit itone of my most favorite conversion's is the RB30 bottom end with GTR headdunno if u guys have the RB30 over there but its a single cam 3L RB engine wat they do is remove the single cam head and bolt on a GTR cylinder head so u end up with a 3L twin cam RB26

oh and since im here heres a RB25 which we put into a 180SX which u guys call a 240sx
