FAQ's
Does the transmission need to be disassembled?
Nope!
Are any modification required on the transmission?
No! Well almost none…you must grind a small portion of the bell-housing to make clearance for the starter nose. A jig is provided to make this really easy, all you need is a die grinder, carbide burr, and maybe 10 minutes.
Are any modification needed to fit the 6 speed transmission in the car?
Yes, the CD transmission is quite large! The factory transmission mounts must be cut out of the transmission tunnel. This is a messy but fairly easy task, they should be smoothed down and undercoated to prevent rust.
Exhaust will also highly likely need to be modified. This is easier on turbocharged cars where a 3" down-pipe can be routed, however modifying NA header is more complex. Feedback from the Z Car Garage is the Pacesetter headers fit the best and can be modified to fit by an exhaust shop.
Does the new transmission mounting cross-member bolt to the factory location?
Since the factory mounts in the transmission tunnel must be removed for clearance the new transmission mounting cross-member bolts directly to the frame rails. Shims are provided to set the transmission angle and we have designs the mount to provide maximum exhaust clearance.
Does the shifter come out at the stock location?
Yes, with the CBF rear mount shifter!
These have been custom made for us with the correct shifter offset.
Is the transmission mount isolator included?
No, the new mount is designed to work with the factory 350z isolator. You may use the OE rubber piece any any of the many aftermarket polyurethane units that are available.
What clutch setup is required?
V2 Kits, shipped after November 2018 are designed to use a 350z clutch. This change was made to allow for wider selection of clutches (and cheaper OE options). A 280zxt clutch (240mm) may also work with the same flywheel spacing, this will be confirmed and updated within several weeks (today is 10/15!). Z/ZX Non Turbo clutches (225mm) will NOT work.
The S30 master cylinder may be used, if you order a clutch line it will connect your stock master cylinder to the 350z slave using braided PTFE hose and nickle plated banjo hose ends.
