Ivey Technologies Stage 1.5 Transmission upgrade


SKU: 201

The Stage 1.5 is our most popular upgrade for the GTR. It is capable of handling 1050 wheel HP+ and over 900 FTLB of wheel torque on our dynojet dyno. It has been used to go as quickly as 8.49 in the 1/4 mile, and over 169 mph.

Some that have used the Stage 1.5:

  • Mike@AWDmotorsports, Alpha 9, and Alpha 10 record holder, 8.61@166
  • David Buschur of Buschur racing 8.75@157,  record quickest on OEM Style turbos
  • Chris L of Boostlogic, 8.9@160 on Bl1100 kit
  • Sean Ivey, Ivey technologies, 8.49@169 A12 kit and stage 1.5 trans
  • Prasad Ankem, Stock turbo record holder 9.5@140MPH


What’s included:

  • Dodson 1st gear set
  • Dodson/Exedy 8 disc clutch
  • Dodson Forged A basket
  • Dodson Forged B basket
  • Dodson Piston shaft seals
  • IveyTrans FWD ( ETS ) Billet ball retainer
  • Dodson FWD Gear Lock

It is still the OEM 2-6 Gears so we do not recommend this trans for over 900 wheel HP, it will hold mostly on short pulls but longer, and repeated pulls will result in broken gears.
