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:
|PPG 1st gear and mainshaft|
|Dodson FWD retainer|
|Dodson Mechanical lock1|
|Dodson Mechanical lock2|
|O ring and seal upgrade kit|
|Oil pump shaft and oil pump blueprint|
|6 magnet Kit|
|Stainless reusable oil filter|
|Dodson superstock 8 Plate clutches|
|Dodson Forged Basket B|
|Valvebody Selector Shims X 3|
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.
