Thread: If you could make your own intake manifold

Prob easy to just used the Xsessive manifold parts with the stock VE flange. Cut it right behind the injectors then form the runners and weld weld. Get the Q45 flanged one and call it a day. Take a look at the one I had made for my VE NX2k. He angled the runners up vs going straight out because of the firewall and ect.

I am not familiar with the xsessive manifold. Pics or links where I can get one?

Okay just saw yours. Looks nice and looks like it could work. A quick Google search yielded no place place to purchase said pieces though.

Edit: found it. Bit more then I was looking to spend. I was just curious about others experiences as my friend and I are trying to r&d so we can make this for others that may want a local option here in AZ to put a ve head on his or her det.

Thanks for the suggestion though.

let there be light. I can't rem if he has the runners up on the web page. If not just call or shoot him a email. Also get the flange for the IACV with one hole not 2.

I <3 that bmc manifold ashton

exactly what I have been searching for...thank you. Not worried about iacv on my car though.



Let me know what you want for them, not really worried about the runners, just want the flanges.

In your case nsusammyeb you should run some shorter straight runners unless you are planning on testing and changing the length a hundred times. They are the easiest design you can just throw on and see some power gains.

Your next concern should be the plenum design, you are going to have around a 2 liter plenum since you have 2L of displacement. If you tamper with plenum volumes you might end up worse off than you started. The plenum should taper to try and get equal air flow to each cylinder 1/4 increment smaller from the throttle body on down. This doesn't effect power as much but engine life.

Here are some ideal designs that funnel intake air well to each cylinder for you to think about these might have even more potential NA with resonance coming into play. Dual Plenum Intake Manifold - K20A.org .:. The K Series Source . Honda / Acura K20a k24a Engine Forum

You don't have to worry about resonance since you are talking about a turbo car, but there are a few things like the funnel shape feeding the runners inside the plenum. They don't need to protrude they can be recessed with equally as good results.

Dual funnel setup looks pretty good. Made a ton of power a lot earlier, though it sucks that power drops off fairly quickly, so if you want a high rev motor it's not for you.

I always figured if I did my own intake manifold, I would try to do a center entrance, and that would likely mimic the lowport intake manfold (curved runners and plenum up high) and point the entrance to the plenum down toward the rear engine mount and fit the throttle body between the firewall and the water pipes. Something like that might work.
