| Turbos - HTT or BD. Both are high quality and well tested. Stay away from the ATS stuff.
Transmission - I have had excellent luck with Suncoast upgrades in the Allison. Most companies are using similar or the same parts as Suncoast. I am pretty Sure the PPE unit is a Suncoast unit, slightly tweaked. if you are looking at al LLY, you should look into a performance VB. Suncoast offers one that will also upgrade the truck from a 5 speed to a 6 speed. For the converter, definently go with a multi disc converter, like the Suncoast triple lock. |
