searching for a intake manifold 50 civic ex
i have been searching for a replacement intake manifold for my d17a2
im installing a turbo kit and looking to replace the plastic factory manifold. what are some of the members doing with boosted vehicles . thank you .

Rep Power: 257 b20 intake mani with the b20 runners welded to the original d17 intake mani flange with a k20 throttle body
ive got an extra d17 intake mani for sale if you want to try some stuff without ruining yours. 35 shipped.

lol there are like 3 b20 manifolds. there is the high rise, then what your used to seeing the lowrise, and also a b18b obdI mani on the b20. i have 2 of them. either way its going to be a bit of fab work to make it fit. if its a f/I set up you may as well go with the d16y8 for the ease of install. its also one of the best flowing stock mani's made by honda
i have over 300 hours into it not even joking all the tubes i had to sand by hand thats where almost all the time came in and thre a big *** spacer that i made where the throttle body comes onto. cost me around 50.00. I had to get a special bit to cut which was 20.00 and 30.00 for aluminum. Can' t wait to get it on

unless you put baffles inside to smooth out the transitions for higher velocity its going to cause you a power loss. if you look at all the custom manifols the boosted guys are having built youll see what i mean. it looks exactly the same. a forced induction manifold need to flow volume so the transitions dont need to be so smooth, it just need to be able to hold a higher volume. a N/A maifold need to be able to flow air smoothly for the highest velocity not volume. here are a couple of articles i just searched for real quick that should help you understand what i am talking about.
first one explains velocity and volume and how it effects power:
Ideas: Flow Velocity, Flow Capacity, Flow Quality - Team Integra
this one explains different designs:
Intake Manifold Tech: Runner Size Calculations - Team Integra
I hope this helps shed some light on the subject and will keep people aware that building manifolds isnt just making one look pretty. the design of the manifold will greatly effect power

take a look at this manifold. i have never see anything like it. i was pretty impressed. i think it would be good for either application.
the larg square plenum design isnt good for flow. you would need to shape the entire inside for velocity. Good N/A I/M's spend countless hours on a flow bench. These motors like longer intake runners stock. what you have is ideal for a boosted car though. dont get me wrong. its just not going to provide you with the same benefit while N/A. it will take away from your top end after the volume of air it holds is used, because it will not flow at a high enough velocity to keep the plenum full. with air being forced in to it there is no need to worry about how fast air is being drawn in because it pressurized.

usually manfiolds arent good for both type of aspiration. but with the correct baffling and fabrication its defnately possible..
+rep for you for doing such a good job and being such a good welder lol
the runners look square but there not i made them out of 3 inch aluminum round stock and i shave them down on the top and bottom to loose some weight adn they got in the way of the injectors. i will try to get some inside shots but i am finishing fab on a bracket for it so its not here and then it off to get polished but i will get you those pictures.
