    Turbo manifold needed for design!

    Ok I'm gonna be construction a turbo manifold for my GT28RS that I'll buy in a couple of months.

    I'll be getting my stuff from Vibrant Performance...

    So I'm trying to decide how to design the manifold. If I wanna use the 4up style or 2up style.

    Does anyone have an math formula's or know any good websites to designing a turbo manifold?... I want to have close to equal runners leading to the turbo.

        Get an already made Evo Manifold. Its almost a direct fit. Ports are off by a few mm. Just chop the evo flange off and weld on your BP flange.

        ....too easy.

        Manifold there looks good though

            Nah mines a Civic one. Evo is much better design and closer. Mine was a fair few mm out.

              I like the 2 up design, gives more room to create space & equal out the runners while keeping a decent height for the oil return.

                  ... so we call that $400CDN with shipping. I'm pretty sure I can make one better than that one... but I'll keep it in mind.
