  • New turbo setup..

    So tell me what you think.. I got my thinking changed a little bit

    Now im thinking still build the tubular manifolds but change the X-over to a 2" rather then the 2.25" i have now.. reason being is the Divided flange will reduce anyhow, so i can build it with the 2" and be perfectly fine... The exhaust pulses are gunna be staggered anyhow so it shouldnt be an issue, what do you think?

    T4 Divided turbo flange:

      No, my bad that wasnt wrote very well, i fixed it.

      Stock X-over is 2.25" on the DOHC and the Divided flange will from what i can see only allow me to feed at 2" pipe into it.. i would think that a 2" x-over should be sufficent..?

        Sounds good to me. The other option is to start each bank at 2.25" then drop to 2" immediately after the wastegate and before the flange. This should improve boost control.
