Don't know anything about the stock s15 drive line, didn't get one with my swap motor, but I would assume it is the exact same as the s13 auto drive line length and all save the oil slinger.

does the transmission plate (between block/bell housing) remain the same 5 vs 6 speed?
will I require S15 part or will my S13 part work the same.... I've searched, with no luck leading me to believe its unecessary... |

Man, I wouldn't weld up an s15 diff, but it will work just fine. The only difference is the gearing. Your diff. now is probably a 4.08 or 3.90 where as the original s15 gearing is a 3.69 so your tach. at 65 will be about 300 rpms lower. Like I said ,though, I wouldn't weld it up, because it's already a helical style posi. which by many standards is the best type of posi. you can get. Yes, of course, not for you drifters, but time attack, autocross, and track days there's nothing better.

only the s15 spec R diff is a torsen unit, the S15 spec S (and tbc the auto) is a standard diff.
Sell the S15 spec R diff with the halfshafts, it is worth a bit of money. Dont get a 6spd from an S15, unless you want to change it often. The late Z33 6 spd is really great even for drifting, as it is quite short and precise. I know a pro drifter using one around here. Full kit (including new gearbox from nissan, adapter plate, machining, propshaft, and maybe labor ) is around 4000€. Another way to make a gearbox "shorter" is the Clarkson way: "POWERRRRRRRRRRRRRR" :mrgreen: |

Speedo gear question:
So I had my s14 speedo drive gear (metal) machined for a 28mm vs 25mm shaft There are 2 clip groves, but the nismo kit only includes 1, so I only ordered 1 The gear is too wide to expose both groves, My guess is; put the c-clip in forward groove and the rear housing holds it in place? Anyone with experience care to chime in? |

Would anyone happen to know:
I have an S14 SR with a Exedy Hyper Single (clutch and fly wheel combo), Would this combo work with the S15 Transmission? Also, can you swap the bell housing between S15 and S14 to allow the use of a S14 Clutch? Can anyone post pics on how to install the VSS ring into the S15.

hello all
pardon me, i dont mean to add clutter to the thread, i only ask because maybe others could benefit from it. how does the 6 speed s15 trans compare to the 6 speed z33 trans? -which one is more plentiful/tangible? -does it cost more to source the s15 trans OR the z33 and adapter plate (and/or whatever else it takes to run it)? -how are the gearings compared to each other? -which one is stronger (id assume its the z33, but i dont want to assume...) again, only trying to help and bring more options and info to the community.

I just backed out of a S15, because the Z33 seems like a better route. Z33 gear boxes are reasonably priced on ebay. I feel the s15 swap costs a bit much for what it is.

Thank you! But what about the actual plastic gear that sits on the shaft inside the tail housing? Am I doomed to track down a blown 5 speed and modify it to work? Or is there a direct replacement for the s15 gearbox?

I have an S14 with a relatively stock S15 motor making 304whp 306wtq and the transmission is still holding strong.
However, I am starting to have some issues with the clutch slipping. I have purchased a new clutch and flywheel, but was wondering; do I have to remove the engine to change the clutch? It says in the OP there's no way to get the transmission in and out with the engine in the car. If this is true that makes clutch changes a real PITA |

Wrong place to ask said question. Try the actual tech section next time, not the stickier threads.
However, it's not impossible to get the trans out with the motor still in, it just takes some finesse.

Does anyone know, can I use an automatic s14 KA driveshaft for the s15 6 speed trans? I found a super old thread from freshalloy where someone said you could. Just looking for clarification before I pay out for a "JDM" s15 6-speed shaft. Thanks.

buy the S15 shaft. the american drive shafts were pieces of shit. the JDM drive shafts didnt use the stupid hockey puck damper on the tranny output shaft that goes to hell in a hand basket (turns into a frayed mess). the JDM drive shafts used standard yolks and a rebuilding center bearing bushing.
or just buy a single piece aluminum drive shaft and enjoy the wonderful 100% direct feeling in acceleration! |
