ok i amit nissans are not bad cars with a little TLC can eat a honda. i know everything there is to know about hondas and did many swaps.. but when my friend said he wanted a 240sx POS i knew that he can drop in some flavor of a JDM nissan engine in it.. i need some one to really give me a crash course in engine code and models .. what can be droped in with ease and not.. i come to understand S14 is just a generation number for the 95-98 and thats the car my friend wants to get..

buget wise he can afford spending up to $3000 on a used engine and tranny not counting changing what has to be done before you drop it in (timming belts,, seals and stuff)..

he would be happy with the stock turbo which he can upgrade at a later time..

what is a SR and RB? what is a fairlady and bluebird? difference in red and black tops.. thanks in advance
