Since Porsche didn’t produce many of the 968 factory turbo models, adapting the 3.0 twin cam intake to turbo duty is a hurdle to overcome when converting to a boosted system. The original builders of this intake welded together parts from a 944 turbo intake and a 968 intake. Because we are converting to E85 for this build, we needed to upgrade the injectors to supply a much larger volume. The easy choice was an LS3 injectors. One concern we had was introducing a larger volume of fuel at the same angle as stock. The LS3 injectors are now aimed directly at the back of the valves instead of the cylinder wall. This should avoid any puddling in the head. A billet fuel rail replaces the inadequate stock unit. We also took this opportunity to remove the electric yellow powder coating and match the intake to the body color, Viola Metallic.
