    hi guys,
    im just wondering if any of you guys know if the 20v exhaust pattern is the same as the 16v? in other words, will a turbo manifold for a 20v bolt to the 16v head?

    thanks guys

    the ports are the same, but the bolt pattern is not the same. the 20v has one bolt offset from the 16v (closest to the firewall in a 86). you should just be able to re-drill the hole to make it fit.

    edit:
    hehe just beat me!

    16v and 20v dont share the same stud pattern. they are close but not the same. you can modify a manifold to suit either tho.

    requires the drilling of extra holes
