Hey just doing the engine swap on my 1992 Integra Base. Ran into a couple obstacles. FYI We are re using the ls transmission with the B16A The car and motor are both OBD1 Does anyone know if this is an aftermarket intake manifold on the B16a? Here is a picture of the B16 manifold beside the old LS one (which is still on the motor). There are several vaccum inputs on the old LS manifold that aren't present on the new B16a manifold. Any input here would be appreciated. where are these vaccum lines supposed to hook up on the new motor?
