C35 Owners
It is very likely that you might be wanting to complete a manual conversion on your Laurel and through research you’ve found that theat results you can find to be quite lacking, through my own experience of doing the manual conversion. I found the majority of information online to be lacking in parts or useful information. Which left me searching forums, facebook groups and OEM drawings for the parts I need.
In order to streamline the process for other owners, I am listing the complete turn key, OEM level conversion list you can use to complete your own manual swap. I will link to a very useful driftworks forum posts detailing some of the basics of this swap. It was largely thanks to @unclebensriceballs original DW forum post that I even knew where to start with this conversion.

When doing the swap, the biggest deciding factor for what parts you need will be whether you go with a RB20 or RB25 gearbox. Below I will outline the specific parts you will need for both. Personally I went with the RB25 as it is a little more simple and more bulletproof for future power goals.
Parts you will need
RB20 or RB25 Gearbox
Complete R33 Handbrake Assembly (This includes the tail) Tail of handbrake will attach straight onto existing handbrake lines
R33 Front Half Propshaft (Will bolt straight to C35 Rear with no issue)
RB20 Specific Yoke
R33 Gearbox Mount (Fits both gearboxes) Might need to slightly adapt the factory auto gearbox crossmember
Nissan Gear Selector Rubber Seal (74967-15U00)
Nissan Shift Boot Retainer (74966-35F00)
Nissan Upper Gear Shifter Dust Boot (74960-91P00)
R33 Nissan Clutch Pedal Assembly Bracket (These are the new part numbers if you can’t find a used one 46550-21U00, 46540-21U00, If you do order new, you will need to use an R34 Clutch Return Spring as the R33 is discontinued 46571-AA000)
Nissan Shifter Boot (32862-05U00)
R33 Conversion Clutch Line
Nissan Clutch Slave Cylinder (30620-21U23)
Nissan Clutch Release Fork (30531-PO151) (Might be included with your used gearbox)
R33 Nissan Shifter Lever (32839-21U10)
R32 GTST Shifter Lever (32839-05U11)
Nissan Clutch Sleeve (30501-SO284)
Nissan Gearbox Bolts x 8 (01121-05121)
ARP Flywheel Bolts (Universal for all RB Engine/Gearboxes)
ARP Pressure Plate Bolts (Universal for all RB Engine/Gearboxes)

Nissan Clutch Pedal Fulcrum Pin (46560-50J00)
Manual Spigot (32202-B950A)
2 x Nissan Snap Rings (32204-V5004)
R32 / R33 Clutch
R32 / R33 Flywheel
Gearbox Reverse Switch (Get the specific one for the 20 or 25 Gearbox)
Gearbox Neutral Switch (Same as above) These can be wired directly to the corresponding neutral/reverse wiring from the auto gearbox
Nissan Shift Lever Insert Socket (32870-V5003)
Nissan Clutch Release Bearing Clip (30514-14600)
Nissan Clutch Release Bearing (30502-69F1A)
Nissan R33 Gearbox Front Cover Assembly (32110-05U11) *Only required with a new RB25DET gearbox
Nissan R33 Gearbox Speed Sensor 25010-21U00 (Should be included with a used gearbox)
Nissan R33 Gearbox Dust Cover (30542-69F00) (Might be included with your used gearbox
When using an RB25DET gearbox, you can sort the speedo by wiring in a NZ EFI RB25 Speed Sensor Connector, this will read accurate KMH without an issue - https://www.nzefi.com/product/nissan-gearbox-vehicle-speed-sensor-connector-r33r34-rb25-z32-300zx-etc/
Warning! This could give you a EML, I currently have one but have not found the source
When using an RB20DET, you can use the SR20DET (Red Gear) speed sensor, this will plug and play and work with no issues
Due to the length of the 20DET gearbox, you will find that upon installation the gear lever will be significantly further forward then you might think and you will need to adapt the auto centre trim to accommodate this. There is no way to fix this other then going for the 25DET gearbox.
Look at the original DW forum posts for an image of what wires to cross to bypass the inhibitor
With this you should be able to complete a full turn key conversion without any issue.
