  • Manifold/downpipe/dumppipe arrangement advantages:
    • Efficient flowpath with consistent boost control
    • Keeps wastegate cold-side in cool air for reliability and easy spring changes
    • Places O2 sensors in ideal location to keep sensor body temps down to prolong life and allow easy access for service.
    • Fewest joints and welds for leak free, trouble free operation
    • Provides ample clearance from all hot-side components
    • Allows use of stock motor mount isolator
multiple turbocharger options

Factory Fit and Finish

Clean engine bay, keeping the heat down low and out of the way, just like the factory intended. Lots of room for a generous sized air filter (important to minimize pressure delta across filter, as small filters can create pressure drops and increased turbo bearing wear, shortening the life of your turbo). Note - it is possible to keep the coolant overflow tank in original location, we just prefer moving it to give a cleaner look, and allow more airflow on turbo side of engine.

$2900"+". Seems the cheapest turbo is included at that price and up from there. Still on the fence about going single, but definitely want a bottom mount, smallish turbo and cast is good, so this might be an option. Any word on how long the intro pricing is expected to last?

Definitely looks like a good setup and an excellent price. Even though I'm glad I stayed with twins despite having a high HP goal, I'm still glad to see an easily affordable single kit for people. Mostly because I think with more people having easy access to higher HP we'll start seeing the other things we need come quicker and cheaper, but I'm still happy for those of you who haven't upgraded yet :p
