Ikeya Formula Dog Gear Set S15 SR20DET. Included are only the internals and can be swapped into the stock transmission casing (The pictured Casing is not included, please inquire for the casing and labor costs). This transmission is equipped with the standard H-Pattern but can be equipped with their very own sequential shifter.
Here is what Ikeya Formula has to say about their product:
Along with developed tuning level of recent years, more people drive cars with high power and it is even not rare to see the cars with over 300ps owned by our user. The importance of transmitting the high power to the ground surface without any loss becomes comes to the front. With these background, we have developed the Dog Clutch Helical Gear which has high accuracy and high rigidity for time attack at circuit and drifting user. The sequential shift has been further adopted for more accurate and quick shift change operation.
Normally, genuine transmission is operated via synchronized mechanism. This mechanism is to synchronize the gear upon upshift and downshift, and this can cause time loss in sports driving. Therefore, we have decided to adopt the Dog Clutch Helical Gear which has no synchronized mechanism equipped therein.
In addition, we have minimized necessity of purchasing specified parts, change of mounting position, or body processing which had been often required for the conventional products, by increasing the rigidity of various parts, such as main shaft, counter gear, main gear.
Considering the maintenance, we have developed the counter gear shaft to be full spline, so that it helps change the gear ratio and replace gear unit quickly which improves the workability upon over haul. Also, it realized the large reduction of the cost, since you can use genuine transmission case.
1st Gear - 2.711 gear ratio
2nd Gear - 1.799 gear ratio
3rd Gear - 1.288 gear ratio
4th Gear - 1.000 gear ratio
5th Gear - 0.812 gear ratio
NOTE: Included is the needed driveshaft which is compatible with this gear set from Ikeya Formula.
