rb20det swap mods

[frainklin crusier]

high i'v just gotten a 240sx s14 and i already have a s13 and i want to do a rb20 swap in one of them.will it be easyer to swap into one than the other?also will i be able to do all the things i need to do to the car to have it running properly after i have the motor and transmission with $1000?and i also would like to know what upgrades would be good for it in the future...please if you can tell me what the exact name of the part is and if their are parts similar to it that are cheaper and work almost the same...also what is the turbo on a rb25?because i think that is the first upgrade i need to get for the rb20

also a few friends of mine have told me it would be better to swap a ls1 motor into it...any oppinions on this?
