ADOPT-specification reinforced motorsports gearset for the Nissan CD009/A 6MT transmission in all applications, including conversions. Features high-strength straight cut spur gears and reinforced input shafts. Drop-in replacement for OEM standard gearset, including all conversions (RB, JZ, UZ, etc.)

Race car type gear whine from spur gears.

Two formats:
Synchromesh, smooth shifts with reinforced internals.
Dog box, true circuit-specification. ETA to market JULY 2026. First orders ship OCT 2026.

Three gear ratio sets:
S1: Reinforced synchro Sports set for road and dual-use cars. 1st and 6th gears made taller for better drivability and commute fuel economy for those with 3.916 and shorter final drives; 2nd-4th more tightly grouped for rowing through gears; 4th shortened so a pull at wide open throttle will be only marginally legal when hitting redline.

R1 Dogbox: S1 with dog gears for enhanced durability under more severe use.

R1C Cross/close-mission dogbox: Dedicated circuit specification. 6th gear has been adjusted to just barely meet the top speeds possible at most tracks on front straights, and 1st-5th have been evenly distributed around common cornering speeds, preventing excessive shifting but keeping the engine RPM between peak torque and peak horsepower. Complete 1st-6th replacement only. 

Custom: Bespoke set of gearing on request for additional fee.

Four gear packs:

1st-6th: complete replacement, including reinforced input shaft.

OPTION: 6th gear, straight cut and reinforced for circuit users. No cost.
OPTION: 6th gear, helical cut and reinforced. Keeps 6th gear quiet for those dailying or commuting with their cars. No cost.

1st-4th multipack: $2200 cheaper for the same benefit, where 5th and 6th can be left OEM. Replaces only the gears used during sports driving.

3rd-4th pack: Budget option to get racing performance (and gear whine) for the most used gears in sports driving.

1st-2nd C pack: A slice of the close-mission, in synchromesh form. Much taller gearing so 1st and 2nd gears can be functional on even short final drives. 

Pricing includes mandatory Federal tariff which will revert to base MSRP if the tariffs are lifted.

Product of Australia 🦘. Lead time: 3.5 months. ETA to market: JULY 2026

Disclaimers: This product is meant to be installed into new transmissions; if retrofitting a partial gearset, additional wear of the original parts may occur from increased load. It is highly recommended that a transmission refresh be done during installation for this reason. 

This is a motorsports product, and will stress all driveline components more strongly than stock. Always be sure your car is capable of handling this increased load, including but not limited to motor mounts, transmission mounts, and differential bushings. 

Returns from improper use, modification, improper install, or damage induced from used/unserviced system components cannot be claimed.

If pump doesn't seem to work
Size: For 85-300 HP, Size: For 85-300 HP
Hi....I apologize it took me a while to get back to you with my results. Here is what I discovered about the pump and will also apply to some of the other comments I read in the reviews with people not getting the pump to work: 1.) I removed the pump to check the proper direction of the impeller and it was correct as can be seen in the photo. 2.) I built a pump shaft attachement so that I could operate the pump with a power drill. 3.) I attached the water muff to the unit and tried to pump water.....it wouldn't do so. What I did see however was that even at high hose discharge and small leakage at the muff I could not fill the water cavity in the housing. 4.) I installed a strap around the muff and tightened it very tight and THEN at high hose pressure I was able to get the cavity to fill with water. 5.) At that point I activated the drill and was able to get the pump to actually pump water. I then removed the pump housing and removed the O-Ring that resides on top of the impeller, reassembled and it would not pump water. Since the O-Ring sits higher than the original does I wanted to make sure that it was necessary to have it in the pump. 6.) I reassembled the engine and kept the tight strap on the bottom and finally it pumped water into the engine. My conclusion that you can reply to other buyers if they have a problem: Do NOT underestimate 2 things....1.)the lack of ability of the pump to draw water up AND 2.)the fact that if the muff leaks it will NOT fill the cavity when common sense says it should. This was a 120hp Johnson. The engine bottom must be immersed fully or the muff must be very tight on the lower unit for the pump to function. Please feel free to post this if you wish.

Incorrect motor listed. Far smaller impeller than what's in the 6 horse johnson.
Size: For 5.5HP 6HP 7.5HP
It seems to be of good quality. However it does not fit a 6 horse johnson as it states. Therefore it will not pump water or function for my purposes. It was a waste of money.
