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 (http://www.anaheimgear.com/). I also had them install the Nismo 6th Main and Cross gear conversion. Please read my thread on the 6MT for detailed information:

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.)

dam this is sick..... bump for you

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.
