1200HP+ 6 Speed Sequential Transmission Universal Fitment Nissan Skyline GTR GTST BARRA GM FORD TOYOTA AWD RWD Z32 Z33


We have received an overwhelming number of requests for the development of a 6-speed sequential transmission, and we are excited to announce that we have initiated the first stages of this project by opening this link for public orders to help fund it. Our goal is to complete this project by the end of 2024, contingent on achieving sufficient pre-order volumes.

This transmission will be designed for universal application, making it compatible with a wide range of vehicles. It is engineered to handle safely over 1,200 HP / 1,500 Nm (1,100 Ft.lbs) on the circuit, thanks to its large center distance between shafts.

Our initial focus for fitment includes options for the Nissan Skyline R32-33-34 GTR & GTST models. It will accommodate the factory automatic bell housing and retain the capability to use the 4WD transfer case and shifter in the OEM location across the Nissan Skyline lineup.

Transmission could be adapted to various other platforms by having a bolt pattern on the front of the Casing to allow a SFI Approved Quicktime Bell Housing, Quicktime make housings for just about anything. (See Link)


Option's on the Input Shaft side of things would be ;
  • 24 Spline NISSAN (Applications upto 600HP)
  • 26 Spline GM/FORD (Applications over 600HP to 1200HP)
  • 29 Spline GM (Applications beyond 1200HP)

    For Pre-Order's we will have these priced the at the same rate.
We would make the front of the Transmission Suit the 8000 series Tilton Hydraulic Release Bearing meaning you could easily adapt any clutch as Tilton make bearings suit various sized clutch diaphragms. (See Link)


Gear Display unit is NOT included but we will be ensuring that you are able to fit the Novotechnik SP2846 Rotary Sensor Potentiometer which is essentially a Gear Display Sensor which would allow you to run CLOSED LOOP Shifts. You can program this to your display unit like AIM, MOTEC,AEM to Display your Gear Position also.

This way of measuring Gear Position is ultimate in terms of shifting speeds and reliability, with shifts as fast as ~38-40mS if tuned correctly, please contact your local tuner to set this up. This unit can be fitted to the front of the Transmission as we provide the mounting hardware to do so. You will only need to purchase the sensor online. (See Link)


Billet Chromoly 4140 Nitrided Shift Forks to ensure no Shift Fork Failure.
Machined Quality Cast Casings with Reinforcements to ensure a rigid design.

Housings included ;
  • Front Transmission Housing.
    Fitment suitable for ;

    - Automatic Nissan Housings Manufactured by Aisin Japan (RB,SR,VG,VQ etc)
    - Quicktime Steel SFI Approved Motorsport Housing - Various engine fitment is offered by Quicktime! (See Link) (LS,JZ,BARRA etc)

  • OPTION 1. Middle Housing & GTR Mainshaft (GTR Installation made easy)

    Fitment suitable for ;

    - Nissan Skyline GT-R AWD Transfer Case
    (Direct Fitment when ordered to fit GT-R RB26)

  • OPTION 2. Middle Housing & Rear Housing Combo
    (73cm Shifter Setback Position - GTST R33/34 etc)

    Fitment suitable for ;

    -RWD Application with Endless amounts of possibilities to be fitted to various cars, we provide a 31 SPLINE Heavy Duty Mainshaft, Slip Yoke suit 1350 Universals & Rear Extension Housing to match with Shifter Location in the Factory Position you see in the RB25DET R33 Skyline .

    (This would be measured from face of bell housing to the Shifter position using the Automatic Bell Housing, be mindful this will vary depending on bell housing, but nothing is stopping you from using a dog leg Shifter to bring the Shifter into the location you need if you are running this transmission in another vehicle)

    - This would essentially accept the factory Shifter Base Plate & Shifter or our Racespec Shifter (See Link)


The transmission's oil capacity is approximately 4 liters when filled. For those involved in circuit racing, the housings are designed to accommodate an external oil cooler and pump, allowing temperature control within the desired range.

This product is offered as a kit, requiring assembly by the purchaser. Instructions will be included, and we also offer a pre-assembled unit for an additional cost of $1,500 plus GST.

How can we provide such an exceptional transmission at this price? By increasing our production volume, we significantly reduce costs.

The recommended retail price (RRP) will be $15,000 once these transmissions are fully stocked and available. We plan to offer fully assembled units for a slight additional cost. Pre-order now to take advantage and save.

What is the main advantage of helical gears over straight cut gears?

Helical gears in gearboxes provide various benefits over straight cut gears including greater tooth contact area, higher load capability whilst offering a smooth, quiet operation.

Be mindful these are intended for Rapid Quick Shift's, very different to a Factory Synchronized Transmission.

The input shafts we manufacture will have a universal fitment. To achieve this, we will produce the shafts with extended length and ample spline length. When placing an order, please inform us of the engine and bell housing you plan to use. This allows us to measure your bell housing and engine combination accurately and machine the nose of the input shaft to the correct length and diameter for the spigot/pilot drive.

As the project progresses, we will keep everyone updated with pictures, drawings, part samples, and other relevant information to provide the latest updates on our status.

We will offer ongoing parts support for these transmissions, ensuring that parts will be available off the shelf in the future. Additionally, with our solid 6-month unconditional warranty program for all our manufactured gearsets, you can be confident that your investment is well-protected.
