I realize that a bore spacing adjustment will probably have to be made which could become a lot of work but still, 160 is probably what I would spend on materials.

10-13-2014, 04:25 PM #1How about cutting the head flange off of one of those $160 Chinese Racing inline 6 polished stainless headers and welding on a mercedes flange? Crazy?

10-14-2014, 06:57 AM #2send the flange of to china and get them to just make one. Limited risk.

larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?
Simpler=Better
10-14-2014, 08:36 AM #3I looked into this a while back, you'd be paying around $150-$200 per manifold. The problem I've heard with Chinese stainless manifolds is that they crack after a couple heat cycles-see if they iwll do mild steel with a heavy (0.1"+) wall.

Yeah, after a closer look it appears that CXracing's schedule 10 (.109") headers are in the $4-500 range. That means the cheaper headers will be thinner. I don't want to go thinner than .1" on a stainless header.
Scratch the whole idea:-(

I can help you out with all your manual transmission, clutch, flywheel, intake and exhaust manifold issues.
My 5-cent on this is how ever crappy you ever build your exhaust manifold it's better than a Chinese dito. So just buy some bends and tube and get going. If you grind some and wrap it up you can MIG-weld it.

Otherwise you need to build with 48mm tubes to get the cone right. 44mm pipes can't stretch that much.
(10-15-2014, 04:31 AM)hooblah I've heard of the crappy Chinese stainless turbo manifolds cracking. You can weld them up and add additional bracing but they still crack.
I'll be making my own in the future, whats the best way of forming an oval pipe for the 606 flange?

That just looks like a flow killer. Wish there was a better way. I too have been worring how I am going to make the tubes work on a om606. That is an option though.
I will speak on my experience with China manifolds and it has been a good one. I bought literally a $100 manifold because honestly if I would have made something ACE Stainless would have charged me 3 times that when I was done. The manifold does look good. It is only schedule 10 but I have ran many 11 sec passes and launched many times on antilag and no problems. When I got it I did have to cut off the T3 flange to get my Precision Turbo to fit but it's a bigger turbo that the manifold probably wasnt designed to fit with. Im a great welder and do all my own fabbing but those kids in China, doing it everyday, are fine welders too! Ebay turbos, that's another story where my experience has been less then perfect.

Word on the street is that you buy an eb*y turbo, and immediately send it to a rebuilder for seals/balancing and you're fine. Never done it myself, but that seems like the way to go for super big cheap turbos that aren't used.

10-16-2014, 08:14 AM #12Did you see the guy who made a 60x manifold from rectangular tubing? It looked like a good way to make a log manifold on the cheap.
