7at 4.08 build
OK, so here we go. I am going to upgrade my 7AT gears from nothing to something. This is my second Z (1990 TT 300 PW), and my first with an automatic transmission. I love the car, but something is missing on the bottom end. I only shift with the paddles, so I still get to shift gears at my command, but I rarely get out of 5th gear. This is not a DD, so I'm not worried about gas mileage...
First, this is a pricey mod. So far, here is what I've bought.
-6speed open diff - $500
-Quaife Diff -$1,100
-4.08 gears and rebuild kit - $800
-Whiteline Bushings - $100
-Install - $900
-Uprev tune to turn off wheel speed sensor code- $950
I found a local shop that will rebuild the manual diff, then swap out my base open diff. I will post a log of how the build progresses.
The Quaife should arrive tomorrow and the gears later this week. I have the rebuild scheduled for 2/6. The hope is that I have everything done and back in the car by late February.
