Default 240sx Faq

I think we should start a 240SX FAQ. Just make it a sticky. I'll help, or even make the damn thing myself if need be, but it just gets crowded when you're getting 2-3 new visitors weekly and they all ask the same questions.

Just basic things. Coupe and Fastback codes, JDM names, SR and KA specs and things...

Just an idea

thank me later; copied from FA

Please note that this is a list of FAQ regarding MODIFICATIONS. If you are looking for specs on engine and/or OE components please use the search function and/or visit websites that have specifications on S13/14 chassis for detailed information.

This thread will be locked indefinitely, and made a sticky. If someone has information to add to this thread, email me at alex@worldwidechang.com or PM me, and I will add to this thread daily. Please realize that this will be a project for many months, and the list is always being updated.

------------------------
Engine (KA)

------------------------
Engine (SR)

-S13 SR OE replacement part number reference list:

Part Part # U.S.-spec source car

Oil filter 15208-53J00 91-94 Sentra SE-R

Fuel Filter 16400-00002 1990-1996 300ZX TT

Upper injector o-ring 16618-53J00 7/95 and newer 300ZX TT (small/upper)

Lower injector o-ring 16618-10V05 7/95 and newer 300ZX TT (big/lower)



SR20DET OE turbo variations:



S13 SR20DET: T-25, 60 trim 56mm BCI-1 compressor, 53.8mm 62 trim T-25 turbine, .64 A/R turbine housing. Journal bearings.

S14 SR20DET: T-28, 60 trim 60 mm BCI-1 compressor in T-04B housing, 62 trim 53.8mm T-25 turbine. .64 A/R turbine housing. Ball bearing center section.

S15 SR20DET: Same as S14, but with Inco turbine wheel (instead of GMR), cast divider wall between turbine discharge and wastegate.

Pulsar GTi-R: T-28, 60 trim 60 mm BCI-1 compressor in standard T-3 housing. 79 trim 53.8mm Inco T-250 turbine wheel .86 A/R turbine housing. Journal bearings.

BB SR20DET: T-25. Basically, the same as the S13 Silvia.


------------------------
Engine (Other)

------------------------
Non-engine power upgrades

-Exhaust systems are chassis-specific irregardless of engine type. This means S14 exhausts fit both KA and SR engines, for example. The only exception to this rule is that S13 CA18DE(T) exhaust systems do not fit onto SR/KA S13 chassis.

------------------------
Suspension

-S13/14 adjustable pillowball upper mounts are interchangeable.
-S13/14 coilovers are not interchangeable.
-S13/14 rear upper arms are interchangeable as long as they are adjustable.

------------------------
Brakes

-For variations of the Z32 300ZX 4 piston caliper, please see this site (written by Asad Aboobaker):
http://www.princeton.edu/~asad/zbrakes/


------------------------
Transmission/Differential

-For Kaaz/Nismo LSD, VLSD output shafts are required. You need two of the following: LSD output shaft 38220-52F01
-Short shifters are interchangeable b/w S13/14 KA transmission and S13/14 SR transmission.


------------------------
Wheels/hubs

-Clearance of wheels for Z32 brake upgrade is entirely dependent on wheel spoke AND wheel design, NOT on offset of wheel.
-Wheel width/offset needed for clearance of coilovers is as follows (disregarding brake clearance):

6" +54 or lower

6.5" +45 or lower

7" +40 or lower

7.5" +34 or lower

8" +30 or lower

8.5" +24 or lower

9" +20 or lower

Please note that this does not take into account variations in offset calculation by manufacturer, or tire sidewall bulge. This list also does not take into account differences in design of coilovers (esp. lower brackets on coilover kits which can cause changes in wheel clearance issues). This list also only applies to the FRONT WHEELS and is intended as a GUIDE for reference.

-The LARGEST wheels that will fit the front of a S13/14 with stock fenders is 9" wide. The rear can take up to 10.5" wide with a very specific offset AND must dial in negative camber. To fit large wheels one must use negative camber to ensure proper fender clearance.

Hub

-S13 uses 30mm front hub bolt, S14 uses 32mm front hub bolt. Both chassis uses 36mm rear hub bolt.
-Conversion to 5 lug on S13 chassis requires S14SE/Z32nonturbo rear hubs, and either 1) JDM aftermarket front S13 5 lug hubs, or 2) S14 SE front hubs + S14 spindle + S14 ball joint w/LCA (and redrilling of strut for larger strut bolt).
-Conversion to 5 lug on S14 requires S14 SE front hubs and S14SE/Z32nonturbo rear hubs.

------------------------
Interior

-S13/14/15 front seats are interchangeable without any modification.
-R32/33/34 front Skyline seats fit S13/14 with a minor modification to one of the holes for the mounting bolts.

------------------------
Chassis Info

-S13/14 front strut tower bars are only interchangeable if the length of the strut bar can be adjusted. Rear strut tower bars are not interchangeable.

No, the 240sx.org FAQ. It covers all of this and 10x more. If they have a question that isn't answered there then I'm sure they will feel fine asking it here.

http://www.240sx.org/faq/index.html

Just look at the list of topics!
