After going through 3/4 transmissions due to broken shift forks, bad syncrhos, etc, I decident that since most of my time in the car is spent on the drag strip, its probably best that I go the automatic route. After alot of talks with Brett Dempsey at BDE (Brett Dempsey Engineering) we decided a reverse manual vavle body TH400 was the way to go. Brett has developed a conversion kit for the VG30 and the RB26.
The specs are as follow:
Built TH400 BDE RB26 Conversion KitJW Aluminum Transbrake w/Reverse Manual Valve BodyTCI Deep Aluminum PanPrecision 5000 stall converterB&M Composite X ShifterCustom OEM 1-piece driveshaftB&M Supercooler TH400 Kit
Now On to the install pics!
Current Engine Bay Setup
OEM Crossmember vs Modified OEM Crossmember
Autometer Mechanical Trans Temp gauge mounted to the Roll Cage
Composite X Shifter
B&M Super Cooler TH400 kit from Jegs
ARP 7MGTE Flywheel Bolts (same pattern as 300ZX/RB26)
Here's the old 5spd, had a pretty decent grind in 4th.....getting ready to come out
A good friend allowed me to use his garage which had a really nice lift and trans jack
A closer look at the tranny & conversion. The bell housing is a modified RB26 automatic bell housing
Here's the difference between the OEM flywheel bolts and the ARP bolts
The OEM bolts stuck out too far, sine the flexplate is thinner than the flywheel
This may be hard to tell, but the RB26 has a dowel pin for alignment of the flywheel. This had to be removed
Trans on its way in
Here you can see the precision converter
The trans went in super easy. The crossmember is mounted to an OEM TH400 tranny mount
Getting the 5spd stuff out of the way
I made my own custom shifter mounting plate using some moderatly thin aluminum. I Just traced the bolt pattern of the 5spd brakect, and cut out, and drilled the bolt holes for this. I then had to drill a large hole in the tunnel for the shifter cable to pass through
Shifter is in, and interior returned in to place
A final look at the interior
Here's the shifter cable routing
I had to custom make the SS lines for the oil cooler
I mounted the oil cooler in the passenger side fenderwell of the car
Here's some pictures of the driveshaft. Its a Z1 1-piece driveshaft for a VG30 application, shortened 1-1/2" I also had to have a 1350 style u-joint installed (Z1 uses a 1310 style) and a 1350 yoke was installed as well. It cost around 100 bucks for the driveshaft shop to do.
Heres the driveshaft engagement. It has a few inches of engagement onto the tail shaft.
I have been driving the car around for a week now, and it absolutley RIPS! The car feels like a totally new animal, and since the car is manually shifted, its just as much fun to drive on the street as the 5spd was. I need to tweak the tune on the car, I think because of the heat, its getting to much fuel (its been adjusted for how cold it has been here lately) so I am getting a little sputter in high rpms because its so rich (10.0 or worse!)
The car is entirely streetable still, even with the 5k stall, the car starts to creep forwards when I let off the brake pedal, and its moving at around 1500rpms.
I am really hoping for some low-mid 10's on pump gas with this setup
Thanks for looking!
