What is the RP in RPS13? and is it applied to the whole 89-94 s13 line?

Here's the break down

S13 - 1989 to 1990 silvia with the CA18 engine
RS13 - 1989 to 1990 180sx with the CA18DET engine
PS13 - 1991-19(I can't remember when they stopped            production) silvia with the sr20 engine
RPS-13 1991 and up 180sx with the sr20 engine.

For the s13 and the ps13 silvia you have three basic types the J's, Q's, K's.  The J's are the bottom of the barrell nonturbo with hand crank windows and no extras ,but they came out with a special race version that had a turbo engine, other than that the J's are all nonturbo.  The Q's are all nonturbo but with some of the nicer stuff in life like power windows and stuff depending what option you get.  The K's are the cream of the crop with the turbo engines and the VLSD.  Also these three types came with different editions like the Q's club edition and what not but that just tells you what trinkets come with the car.

The 180sx's were all turbo charged except for the kouki(late model) type S.  I have no clue why nissan did this.  Also the 180sx comes with two different types of SR20DET engines a red top and a black top.  Now this black top is different from the ones in the s14 models. its a step up from the redtop but doesn't come with the variable cam timing  like the s14 black top.  Oh and all 180sx except for the Type S I think came with vlsd's.  I know that just about every turbocharged car in japan comes with some sort of LSD.
