Good Morning Mr Casas

Thank you for your enquiry regarding KAPS Transmissions 6 Speed sequential gearboxes.

KAPS for many years have produced Dog Gearbox Kits for Subaru, Mitsubishi and other makes for competition use… now a fully sequential gear changing unit is available. Using the similar Dog ring engagement and coupled with a custom gear selector drum, seamless gear changes can be made!

KAPS have supplied Sequential gearboxes to Japan, USA, Belgium, Czech Republic and Australia. Approximately 6 units are in active competition use and their primary applications have been in Rally Cross and Rallying. One Rally Cross car has been noted of running a KAPS Sequential Gearbox with 780nm torque and 500HP without problems.

KAPS produce the sequential gearbox from KAPS custom parts and Standard Series parts (e.g.: Subaru Standard 6 Speed), so a donor gearbox is required for assembly.

Standard series parts required are:
-Front housing
- Differential
- Crown ‘n’ pinion
- DCCD Unit
- Rear housing and other smaller series parts.

The common front and rear housings allow for easy compatibility between manufacture’s vehicle evolutions (e.g.: Subaru 1992 GC8 thru to 2007 GDB Models).

The complete KAPS Sequential kit includes the following items;
- Straight cut Dog engagement gears
- Special Sequential gear selector drum
- Shifting Rollers, Forks, Shafts and other essential parts
- EPS Cutting Sensor and computer (patent for KAPS)
- LED Gear display and wiring loom
- Sequential shifting lever
- EPS Computer software
- Gearbox service manual

EPS Cutting System cuts the fuel injection to seamless make full throttle gear changes possible (without use of the clutch). Cutting times can be varied for each gear on the EPS computer via a laptop computer (USB connection). Typically 1st gear 125ms thru to 6th gear 80ms cutting times. Shifting lever force can be modified as well.

Basic price for KAPS Sequential gearbox is: 23000 Euro
(full assembly with customer supplied donor gearbox is approx: 28000 Euro)

Some additional points of interest about KAPS Transmissions Subaru Sequential Gearbox are;
- Approximately 10kg lighter than Standard 6 speed (without oil)
- Can use STI or other front LSDs in gearbox.
- Centre gearbox housing is KAPS custom CNC machined.
- Meshed internal oil ports prevent metal particles from moving around gearbox.
- 1:1 drop gears (3.9 ratio rear differential required)
- Standard prop shaft length may need to be modified to fit gearbox.
- Reverse gear can be selected from 6th gear (when car is stationary)

If you have any futher questions, please do not hesitate to contact me.
