EVOLUTION-8/9 STAGE 1 EXCHANGE SERVICE 

EVOLUTION-8/9 STAGE 2.5 EXCHANGE SERVICE

We have in stock, our popular EVO-8/9 STAGE 2.5 EXCHANGE transmission for the 2003-2007 Mitsubishi EVOLUTION.  These transmissions include everything found in the STAGE 2 REBUILD including these important upgrades such as the taller EVO-9 1st and the EVO-8 3rd/4th gearset and now shot peening. The EVO-9 1st gear is stronger and has a better gear ratio than the EVO-8 1st gear.  The transmission also is built with the EVO-8 3rd & 4th gearset because the gear ratios are better suited for road racing as well as drag racing. We can also build the transmission with the EVO-9 3rd/4th gearing for those who need shorter gearing for rally type work or autocross. More gear ratios are available, click here for more info. These transmissions have been modified for severe duty and have proven themselves to be able to take the punishment of a full years worth of road racing in the fastest EVO that race in SCCA T2. This transmission is disassembled and receives gear detail work to the lead edge and root diameter of the gear teeth which allows the gearsets to handle higher torque without failure.  High rpm shifts are not a problem because the engagement teeth are modified to increase the window of opportunity. Oil passageways are enlarged to deliver more oil to critical parts. This transmission will also fit the EVO 4 through 9, an excellent upgrade for the older EVOLUTIONS. Conservatively rated for 425ft.lbs of torque yet it can withstand 650ft.lbs making them ideal for high torque stroker engine applications.
