CA S15 6 Speed Conversion for any SR

[xpertsnowcarver]

I'll be selling my last S13 which has a S15 6MT(in a couple of weeks), so I'm letting go of my backup/racing S15 6MT.

SOLD! SOLD! SOLD! Please Lock!

$1000 OBO (+260 OBO Option. See below.)


The tranny for sale is the bottom one, which I marked with JW.

I used this 6MT for racing. I had the transmission stripped down and inspected for gear and synchro damage with the help from Eric and his crew at ANAHEIM GEAR. I also had them install the Nismo 6th Main and Cross gear conversion. Please read my thread on the 6MT for detailed information:

S15 6 Speed Transmission for Dummies Thread

Some footage of experience with 6MT and road racing:

What you get:
- S15 Spec-R Dual Mass Flywheel
- S15 Spec-R Clutch Kit
- S15 Spec-R 6 Speed Transmission
--- Nismo 6th Main and Cross Gear Conversion (Installed)
--- Shifter is included
--- Clutch fork and boot included
--- Release bearing assembly included with Fidanza Self-Centered bearing
- S15 to S13 One-Piece Steel Driveshaft (Length-wise, it may fit on S14, but I have not personally tried. I am not sure, so this is up to the buyer.)
- S15 Spec-R Transmission Cross-Member

Optional: I have an Autech (Nismo and Exedy Stamped) Flywheel that is 11 lbs lighter than the OEM Dual Mass Flywheel. Add $260 OBO. You keep the Dual Mass Flywheel as well.

Any questions, please post hear, so I may answer openly. Those who would like to meet and/or make an offer, please PM me.

== No shipping. I don't have the time or care to bother setting that up.
== No parting out, except for the Autech Flywheel. (Willing to sell that separately for $330OBO shipped.)
== Paypal accepted, but buyer must pay any fees.

Another close up of the S15 6MT


Shifter included of course


OEM Spec-R Dual Mass Flywheel with OEM Clutch Kit (Yes, it does not have a sprung hub, because the Dual Mass Flywheel has a sprung hub internally. See the 6MT for Dummies Thread for more information.)


Comparison of the OEM Dual Mass vs Autech Flywheels


The crossmember needed for the transmission to mount correctly.


Graphical comparison of gearing ratios for a 5MT, 6MT, and Full Nismo 6MT


This shows how much closer 6th gear is brought to 5th gear.


These is the Nismo 6th gear set and their boxes. (Gear Ratio changes from 0.764 to 0.8624)


This is the Autech flywheel showing the Nismo and Exedy stamps (Hard to see the Exedy stamp, but it's directly across from the Nismo stamp)

What method did you use for the VSS? Since you didn't mention it and one of the pictures shows that the vss hole is cast molded shut, you didn't go about it this way.

Great question. I've found that, regardless of whether the VSS hole is cast shut or is drilled and capped, neither have the plastic driver gear to turn the sensor. Personally, the easiest method was with the use of a differential that has a VSS. (I used an imported S15 diff with a HLSD. However, a viscous diff from, say, a J30 would suffice.) With the use of a Dakota Digital unit, one is able continue using the speedometer.

Bump for you sir, very well writen post. Glws

What differential was in the S13 with the S15 6-speed and what driveshaft did you use (driveshaft shop, custom, etc)?

[xpertsnowcarver]

The S13 I had used for track use only had a S15 differential. However, I had a one piece aluminum driveshaft in that application. I had not used this steel driveshaft.

The current S13, which I daily, has the original open differential. I had used this steel driveshaft, before installing an aluminum driveshaft. This steel driveshaft is from Driveshaftshop. I am able to confirm that this steel driveshaft is long enough to fit an S13 differential without a VSS.

Side note:
In comparison to the current aluminum driveshaft my current S13 has, the steel driveshaft is, in fact, shorter by approximately 1.5 inches (visual estimation). That being said, I suppose this steel driveshaft may be short enough to fit a differential with a VSS. I am uncertain how this would contrast to an S14 application.

Hope I was able to answer your question. I used the word driveshaft ten times, and I started to confuse myself. Haha.
