Just to let you know guys that we will be making some turbo manifolds for an eco build that we are starting in Feb. I will post up some pics when we get it done and maybe I will offer some on here if anyone is interested.

Looks well made. Only thing I see is the turbo will set way down! Also no wastegate flange on it.

looks good, wonder if it would help a gt35r fit better??
yeah i saw that a couple days ago but didnt pay any attention to it. nice find.
thats really how all eco manifolds should be made, you go three inches under the manifold, and youve got a world of room to play with. my down pipes taken me forever to build.

they should be able to do wastegate flange easily, that thing is BA, probly the one I will get when my new cavy takes frm, unless raven's is better

im really interested in seeing your design raven
Only problem i see is that the runners are not larger then the port... From things ive read you want the runners larger then the port on the flange to create a "lip" on the flange to the runner as to decrease back pressure.

Que?
1.5" sch40 is equivalent to 1 3/4 16gauge primaries. I gaurantee the ECO head ports don't have a cross sectional surface area larger than 2.03583 in^2
I should also add that you guys should see what someone asked. I don't know if it was one of you guys or what, but they strictly use a T25 flange. Not that it is a huge problem to get it modified or cutoff and have a T3/T4 flange welded on, but I don't think the guys building these have any idea what is the most appropriate size of turbine for an ECO. Definately quality stuff though.

"Youth in Asia"...I don't see anything wrong with that.
itr says in the add that if you need a t3 flange to get ahold of them and they will build you one

Its hard to explain i guess. But looking at the manifold i thought the ports were the same size as the ports on the head. oh well.
I Wrote to them. n asked bout the External Waste gate n what not. and here is what they said..
"Hello,
We try to keep things simple for us and for everybody as well. We use the T25 flange because it allows us to install Gt25-based nomenclature turbos that comes with internal gates. There is a large array of very good turbos available from Garrett with the T25 flange such as Gt28RS, GT2871R, and GT30R. Any of these turbos is very well suited for the 2.2liter engine, as long as you chose the correct A/R for the purpose you intend to do. The GT3076R per example will support over 450hp and is available with internal Waste gate port turbine housing. There are quite a few hoses, cables and stuff running around near the firewall, at the back of the engine so its always best to have as little hardware as possible in that area. My opinion is to avoid the use of an external gate when it’s not necessary.
Still, having a T3 flange welded to it is not a problem at all. You must understand that it’s nearly impossible to weld a Waste gate flange that would suit everybody’s own Waste gate.

I'm very interested in this as well!
That thing is not that well made, and it's really not worth the asking price. The welds look to have some undercut as well as it looks like they were all done with a single pass, instead of a root then fill. It's made from mild steel weld els and not the good ones, you can tell by the sand casting pattern on them (good ones are extruded). It's not a horrible manifold but I don't personally feel it's worth $400.

With that kind of response I would never buy from them. Seems they feel they know all.

Well I guess i'll just wait for the right Turbo Mani to come out. Either its not made good enough or they want an Arm or a Leg.
I love that Turbo Header!
skilz-is it true that you blew up ur motor?
have you seen this one made by garrett? Pretty sweet setup. Now it's for the cobalt but the 2.2L so it would only take a little tweaking to make it work. I would get it if I didn't already have the HAHN

total kit.

One problem with that kit Eco, and that involves the way the airfilter pipe is run. It runs up around where the A/C is on jbodies and then continues to go down and disappear into the front of the fender well. Also, the I/C piping runs over the top of the motor (I think it would make hood clearance) and I dont know if it would clear the stock intake manifold (are they the same on cobalts and jbodies?) Also, The way the intercooler mounts is based on the front bumper support which may or may not be different, not sure on that either. I wonder if the O2 housing outlet would be in the same spot for the Jbody downpipe and if its even the same pattern. In either case, that manifold design and turbo take up a very little amount of space. Could be worth finding out...

oh believe me like I said I love my hahn manifold. but this kit would take some fabricating. I custom fabed my intercooler and intake pipe with your turbo and manifold. I just like the runners on the exhaust manifold. that is really all I like.
