WM using his honda ingenuity thinking theories again: ca18de CUSTOM INTAKE MANIFOLD

WMengineering · Aug 18th, 2003, 02:25 PM

what am i looking at your asking?
well its a one off integra LS(b18b1) intake manifold plenum mated to D16z6 (sohc) runners and fuel injection set up. the idea is that the integra plenum flows better (however testing done concluded it did not)

but, still brownie points for the engineering thought behind it. now....my question.

anyone ever tried this with the ca18de? how about the shit box IM ga16i? i have heard that at least with the ca's, you can use the turbo mani on the NA, which is more like this MPFI elongated side port honda IM above. correct?
my reasoning is just that this ga16i IM is a bitch to come up with an intake for, and the ca18de is jusst sorta wierd to me. (alltho you should see what i have drawn up already...think custom ram air hood scoop for the ca18de manifold...hehe)

anyways im mostly trying to inspire some theorizing and good discusion here. have at it ppl.

**IM=Intake manifold for short hand if you didnt know.

Well, the CA18DE has a three-piece, eight-port connection to the head with a butterfly setup on the secondary runners. There are two pieces that connect to the head, they have four runners on the maniflod side and eight on the head side. That thing may be able to hook up to that part but you'd have to run the injectors on the 4-to-8 portion of the CA18DE manifold. I'll get a pic of the CA18DE manifold later. Mine is currently off the engine.

Here's the upper section of the manifold.

what fuel rail and injectors are on that integra manifold?
