    Pulleys

    I bought an 03 with a trilogy already installed. I am veing told that I need to change out the pulleys to add more power. Can anyone point me in the right direction as far as where to buy and which ones to buy?

    Trilogy pulleys are apparently hard to come by, I tried to find a 3.0 and no one I found is making the magnuson keyed pulley. What size do you have? stock which is 3.4? Maybe someone here has a 3.2 they would sell. You will need a new tune when you change a pulley.

    Billet flow should work, it's still a eaton.

    Billetflow used to carry trilogy ones, but they no longer are. I just asked them 3 weeks ago

    A year ago I couldn't find anybody that still made them or had them in stock without going custom. In my searches I was able to find a used 2.8 that was kinda beat up but it still would work fine. Ive thought about looking into have a custom hub made to use a billet flow ring because i have access to cad software and a 3D printer for a prototype, but i still don't have a boosted marauder due to constantly changing which car i want to put it on so it hasn't been a priority.

    You need to change belt size too, if you change pulley diameter.
