    Hey guys needing a turbo upgrade for C15 Accert SDP engine, Currently running B/W 550 hp wastegated turbo but it's to small. I no nothing about engines on the tech side other then there expensive lol

    Looking for roughly 800hp turbo. I am running just over 600 RWHP according to the dyno with only roughly 26 pounds of boost

    And should I go wastegate or non wastegate and what a/r?

    Beem leaning towards b/w s410-sx

    Thanks

    Not wise to go bigger than stock unless you do injectors and everything else to support bigger. I learned the hard way. Sure you will get more boost and you wont even feel an increase when you hit that boost. All you will feel is a complete turd of a truck becuase it takes forever to spool up. If your motor is all stock, stay with the cat turbo size.

    Don’t be hung up on the boost number,

    you will have to buy an exhaust housing with the 0003. The 1.65 it comes with is not gonna work well with your setup.


    To be clear he asked for a turbo in the 750 range I answered his question.
