Ok, since there have been 3+ posts per day regarding wrong information on the 180sx alone, I wanted to make this list in hopes of possible sticky-dom...
Ok:
_S13: chassis code for all 88'-93' JDM Silvias, 89'-98' 180sx, '89-94 240sx coupe and fastback, Aussie and European 200sx ( I don't know definite dates...).
S13: Silvia with CA18DE(T) ('88-'90)
+Trim levels
-J's N/A base model
-Q's N/A full package
-K's Turbo with full trim package as well I believe.
+Club's models had even more options
RS13: 180sx with CA18DE(T) ('89-'90 a.k.a. zenki)
+Unsure on trim
PS13: Silvia with SR20DE(T) ('91-'93)
+Trim levels
-J's N/A base model
-Q's N/A full package
-K's Turbo with full trim package
+Club's models had even more options
RPS13: 180sx with SR20D(T) ('91-'96.5 a.k.a. chuki and '9.5-'98 a.k.a. kouki)
+Chuki trim
-Type-S: SR20DE and no standard aero kit (probable)
-Type-X: SR20DET and aero lip, side skirts and rear underspoiler (also probable)
+Kouki trim
-Type-S: SR20DE with no aero kit
-Type-G: SR20DE with aero sideskirts and rear underspoiler
-Type-R: SR20DET with no aero kit
-Type-X: SR20DET with aero front lip, sideskirts, and rear underspoiler
Visual differences
Zenki/chuki 180sx have same tail lights as USDM 240sx hatchback. Zenki has "pignose" front bumper.
Kouki has updated, more modern lights and different bumper and aero sideskirts.
CA18DE(T) Silvias had non-projector headlamps, while the SR20DE(T) models had projectors with option of 2/3 projectors and 1/0 reflector fog lamp. (info from a trusted friend in japan)
RHS13: 240sx with KA24E
RMS13: 240sx with KA24DE
+Same differences (bar engine) as the JDM zenki/chuki models regarding bumpers, although ou chuki RMS13 did not come with the same aero package as JDM version's
+Also, various JDM/USDM differnces such as cdigital climate control on some kouki 180sx, brakes, brake cooling fins attachd to T/C rods, thicker JDM Sway bars, kouki 180sx seats, steering wheel (airbag), manual seatbelts, etc..
Zenki S14: '94-'96 Silvia, '95-'96 240sx
JDM: SR20DE(T)
+Trim levels
-J's N/A base model (green with gold badging)
-Q's N/A full package (black with silver badging)
-K's Turbo with full trim package (red with silver badging)
USDM: KA24DE
+Trim levels
-Base
-SE
Differences include (but are not limited to): bumper, aero additions such as: side skirts and rear pieces, orange signals on (some) JDM versions, digital climate control, and various other ones I can't think of or don't know.
Kouki S14: '97-'98 Silvia and 240sx
JDM: SR20DE(T)
+Trim levels
-J's N/A base model (green with gold badging)
-Q's N/A full package (black with silver badging)
-K's Turbo with full trim package (red with silver badging)
USDM: KA24DE
+Trim levels
-Base
-SE
-LE
Differences are similar as zenki's between JDM/USDM models, but kouki/zenki differences include: LE trim package for USDM, different headlights, hood, grille, fenders and bumpers as well as slightly diffeent tail lights. Also JDM version had a different rear wing, front and rear bumper and front/rear aero add-on's. (gasping for air)
S15: '99-'02 Silvia and Aussie 200sx.
Basically (concerning JDM-only since i can't be positive about the Oz version):
Spec-S came with SR20DE and Spec-R came with SR20DET. Both had aero packages that were options, and both were offered in 5At and 6MT, althogh the 5AT in SR20DET version has (iirc) a power decrease. Also, it was not possible to get the full aero options and SR20DET without getting the 6MT. (maybe it was just certain options, but the price sheet i have shows one version only availabe in SR20DET 6MT).
Also, the N/A SR20DE has an Autech version that is pretty sports-oriented...
Engine valve covers and appearace:
'88-'90 S13/RS13 CA18DE(T): Red valve cover and black coilpack cover.
'91-93 PS13/RPS13 SR20DE(T): Red valve cover, flat top. T25 turbo.
'94-'98 RPS13 SR20DE(T): Black valve cover, flat top. T25 turbo.
'94-'98 S14 SR20DE(T): Black valve cover, hump peaking over cylinder 3. VTC on intake and has T28 BB turbo
'99-'02 S15 SR20DE(T): Black valve cover, hump peaking over cylinder 3, TVC on both intake and exhaust, and BB T28 with inconel (light metal used to supposedly spool faster..)
+Autech S15 SR20DE has red valve cover, VTL on both cams, a stainless steel header, and no center cover (distibutor set up, not coilpacks like DET).
Ok, that is pretty good. Boro240 is going to post some pics for me since my home computer sucks, and I will edit this if i come up with or learn any new info. Enjoy, and I better not hear any "Type-X bumper" mis information if this becomes a sticky...
