S14 (SR20DET) manifold

[henrix]

sorry if this is a dumb question.. but will a manifold from a SR20DET engine fit on my FJ20E engine? any one who knows a little about this?

no it will not mate, i'am doing the fj20 turbo conversion and have looked at that option, it would fit by making a new flange and widening the runners by a couple of mm, but i'am using the rb26 manifold, the 4 middle ports just about fit, so we are widening those, then welding onto the new fj flange, the 2 end ports are being used for external wastegates.plus the sr20 manifolds that i've seen are not long enough lenght runners for the high reving fj's, the rb manifold has longer runners.
