Got my 6MT vlsd pumpkin today! See picture. Set of 3.7 gears plus seal and bearing set on its way from Z1 Motorsports.
Next weekend I install the Stillen underdrive crank pulley, and after I get the gears next week the pumpkin goes to a local trans shop for a rebuild with the 3.7s.
Damn, you don't play around... Nice. Personally, I tend to stay away from 'underdriving' pulleys. As I'm sure you know, it can put positive/negative strain on accessories. I'd go with lightweight, not underdriven.

More fun ahead!
where did you end up getting it from LKQ?
How is the shop that you are going to? Are they familiar with nissan diffs? What are they charging to swap gears and fully rebuild it?
Yes, got it from LKQ for $165 plus shipping, from a 2006 6MT Enthusiast model totalled in a front-end collision. Looks to be in pretty good shape with no visible leaks, but I'm getting it rebuilt anyway.
There is a small shop right on the way to work for me in East Hanover, NJ, called Morris County Transmissions. They only do trannys and differentials. I sent them an email but haven't talked to them yet. Once I get a quote I'll let you know.
By the way, I also purchased the Z1 polyurethane bushing set and bushing tool. I figure since I'll have the diff out why not replace the failure-prone fluid-filled bushing too.
Normally would take about 4-5hrs cause you have to put it together and then take it apart to make sure all is good on clearances. do they planing on cleaning housing before rebuild ?
need help installing it? cause i am going to be doing mine, so wanted to see how much of a pain it is to take out that subframe bushing

I didn't ask him to clean the housing - it's pretty clean and degreased already and it's going where no one will ever see it, so not a big concern for me. Maybe I'll paint it if I have extra time before the install.
Ill be doing it in a few weeks with my brother-in-law; between the two of us we should be good. The bushing will be the big headache but the special removal tool from Z1 should help in that regard. I'll try to take pictures along the way.
I'm very frustrated. I have been working on the car since yesterday pm, and I cannot get the crankshaft pulley bolt off to install the new Stillen underdrive pulley, even with a 3/4" breaker bar and 3 foot extension and a steel pulley holder tool. I bent the pulley holder tool from all the force I was using (see picture). The bolt didnt budge! So...
I put the car mostly back together and took it to the local mechanic shop. Very good shop. They said, sure we'll do the whole install for you for $130. Great, I said!!
One hour later the mechanic comes out and says he can't get the pulley bolt off either, even with his professional air tools! They didn't charge me but I'm still disappointed. Guess the new pulley goes up on ebay or the marketplace. At least I didn't break the car.
Now I'm home and I'll eat lunch, jack the car back up and finish putting things back the way they were. Still have the diff install to look forward to, though!
Those two pins are supposed to be straight and in line with each other!
After the underdrive pulley fiasco, I decided I needed to do something else while waiting for the gears, so today I installed a set of Works Bell carbon fiber paddle shifters. Took me pretty much all day, most of that time spent figuring out how to take apart the steering column, scuff panel, console, where to get the power and ground from, etc.
Ended up tapping into the cigarette lighter for power and drilling a chassis bracket under the dash for the ground. Put it all back together and voila, it works. Still optimizing the paddle position but combined with the Transgo Kit the fun factor is definitely high!
Should be a nice combo with the 3.7 gears. Can't wait...
Still haven't gotten the diff back from the shop. Should be ready some time this week; I told him no hurry and I guess he took it to heart...
Looking at next weekend for the installation; right now I'm on my way to London for work.
Well not sure if model year matters or not, but my '03 5AT with 3.7 gear, I have no CC. I turn it on and the light just flashes.
But I wouldn't change it back at all. I love have the 3.7 gear because you really get to take advantage of the low-end torque if you have supporting mods. Just take'er easy for a couple of weeks even after break-in. It'll take some getting use to depending on how heavy your foot is, haha.
Thanks for the feedback, Waldo. It's my understanding that the CC issue only occurs in 2003-2004 Z's, with 2004 1/2 being the approximate cutoff. I guess I'll find out soon enough.
It will be tough to baby it at first but maybe just a few short bursts won't hurt...;-)

Did you swap out the LSD as well or stuck with OEM?
Differential is ready. $500 for the rebuild. He said he had to pull it apart 4 or 5 times to get the shaft run-out right with shims, not a simple procedure...
I'll pick it up when I get back from the UK, then slap it in. Stay tuned.
Wow.. Now that's a Pinto I would not be ashamed to drive.. I remember doing that to the old Chevy Vega's too back in the day..
