ETV R gearbox

The ETV-R gearbox has been design to fit Honda B serie engines type (B16, B17, B18, B20, B21). We have developed a simple concept by designing and producing specific casings to assembly ETV internal parts in a 100% specific gearbox. The starter is repositioned at the front of the car in order to save space around the selector area. The clutch casing is as short as possible in order to avoid any interference between the cluster casing and the chassis leg. From its first race in 2018, the ETV-R conquered its public with the very fast Irish rallyman Gary McNamee. The ETV-R now equips many Honda Civic, Integra or other CRX. Its high torque capacity (from 350 N.m with short final drive to 500 N.m with long final drive) makes the ETV-R naturally qualified for lots of applications, whereas its modularity enables to offer a specific solution for every new project. The integrated oil pump function allows you to tackle high revs motors without fear for your transmission.

To optimize your speedness diagram according to your application and your technical datas (engine, tyres, etc), there are dozen of ratios for each gear ratio and more than 10 different final drives are in stock.

A 4+4 discs version (16 friction faces) of the self-locking differential is available fot the most demanding projects on this matter. The 3+3 discs standard LSD (12 friction faces) with 40°/60° ramps (or 30°/60°) offers a high end differential which meets 90% of the project needs. Since 2019, our differential benefit of molybdenum friction discs. The molybdenum is a high performance friction material. It has a high level of elasticity and improves the characteristics of steel at high temperatures : smoother, higher coefficient of friction, better life-time.

Aditionnal technical information

  • Clutch has to be a cerametallic simple plate or Sintered twin-plate Ø184mm maximum. With 1" x 23 splines disc.
  • The original flywheel cannot be kept as it is not compatible with a Ø184mm race clutch. We recommend the use of the TTV flywheel.
  • The gearbox is compatible with OEM 41 splines output flanges from Peugeot Boxer/Citroën Jumper. Machined from the billet reinforced output flanges could be offer if necessary to meet the technical requirements.
  • Driveshafts have to be custom-made. We advise Ø28mm maximum.
  • To install the hydraulic release system, a minimum 0,7" master cylinder can be instal on your original clutch pedal.
  • There is no slave cylinder stop, so a pedal mechanical stop is necessary.
  • According to your application and the technical datas of your vehicle, a cooling system could be suggested. Most of the time, we advise a 13 rows oil cooler with 210x98x50mm dimensions.
  • It is necessary to use 75W140 oil type.
