I came across this manifold in another thread. It looks nice and its inexpensive as well. Maybe too cheap ($350 shipped). It claims good flow characteristics for the gt35r. Here is the link to the site

I dont understand why the flange has that four way divider even though the runners are not seperate? And looking through the wastegate port...I wouldnt think those ripples on the inside of that runner would be very good for exhaust flow.

 

If you go to the manifold thread CLICK HERE It looks like there is a member with that manifold send him a PM and ask him some questions. But IMO when it comes to F/I you get what you pay for.

 

Yea that is where I saw it. I will pm him or have him post some #'s of what it can do. And I do understand the concept of you get what you pay for. Well most of the time that is the case. Would a log style manifold be efficient enough for an application like this. I think that my goal is rather modest and attainable. I am aiming for 15psi, and a nice wide powerband. Right now my vtec is set to 7500. It sucks because I can't rev that high in town and gets the wrong kind of attention . I would rather have vtec set at around 6000. I think that I read log manifolds can't really do that.

 

The runners are seperate, this manifold is not a log, it´s actually tubular in design but the tubes are CNC machined to shape. Looks a lot better than a log.
One collector for turbo and one for WG, pretty cool.

I´m sure this manifold will do a great job for most people, will lose a bit on top compared to real tubular but I bet it´s great for low end torque.

 

why not just go with a proven one like Pfab, Full Race or IP, sure its more $$$$$$$$$$$ but in the end you will be happy

 

if u want this mani, do it with a gt30 sized turbo and you will have a nice broad powerband

 

How about a Borg Warner check out inlinePRO recent build CLICK HERE Its a different manifold but it gives you and idea you could be close to that with some more boost.

 

i saw this manifold a couple years ago on display at a dyno meet. it looked good but i could never find any info on it. i agree with the gt30 instead of the gt35. i say go for it. it can't be any worse than the revhard manifold. i would buy one if i didn't just buy an inline pro manifold.

 

With the more expensive tubular manifolds (i.e. Full-Race, IP Stage 2, AFI) they make more power with less boost (which should always be the aim). Cast manifolds like IP Stage 1, Ultimate Racing, ect. require more boost to make better/similar power to the other manifolds listed. Take a look at the power charts which are stickied. I've been working on them for quite awhile and it's very easy to tell that the more expensive manifolds tend to flow much better than the other ones due to their design.

One easy way to see that the new DSport with the S2000 on the cover lied about his power numbers are looking at his boost, torque (and lack of a chart for torque), and the dyno graph. 15 PSI on a IP Stage 1 kit with a 35R just doesn't add up.
