I paid $600 USD for this manifold. Do you think it will perform better than stock? I don't think I got ripped off, but because there are not many people who stock Evo parts, it's hard to compare price.

There's a fair few burrs in the pipe, which I will be using a dremel to get out, and I am going to ceramic coat it. There's also no bracket for the heat shield, which worries me. I might fabricate my own.

Anyway, tell me what you think.

 

From another angle

 

What...you live in Australia and you can't find Evo parts...are you blind?

 

Umm, like to help me out?

Everything so far, I've ordered in from Japan.

BTW, did you know that officially there are only 100 Evo 6.5s here, + a handful of small volume imports? Still think it's gonna be easy getting Evo parts?

 

I was under the impression that Oz was the evo capital of the world outside of Japan.......Sorry for the comment I must have been missled

 

Looks really good! Not sure what the bong/pipe looking things are, but other than that, I like!

 

*lol* Those are for the disabled "Anti-lag" system.

The AL system has been turned off for the street, so I don't know why it's important to keep them there. I've been told to be careful not to block them up when I ceramic coat it.

I have found this manifold to be pretty disappointing:

1) The runners aren't equal length

2) It's not made out of one piece mandrel bending - they are lots of pipes welded together

3) Where the pipes are welded, there are significant protuberances into the passageway, which will cause turbulence and resistance.

I spent about 6 hours last night polishing these out, and I'd say I'm only about 1/4 of the way done. This will be a long job to get this manifold to be free flowing.

But other than those, I do agree with you... It looks Bling Bling, and as long as I don't lose any power, it'll still look great under the bonnet. (Expecting to gain a little bit from all the polishing I've done on it - I'm not expecting much if anything from the design)

Limey,

I think why you might have been misled, is because of our import laws. While we have only officially gotten 100 TMEs, the 3, 4, 5, and 6, were all on the "Specialist and Enthusiast Vehicles" list. This means that if you want to specially order one of these cars from Japan, you could. It'd cost you an arm and a leg, but you could do it (Japan paid about $30K new for them, if you import through SEVS, you paid about $80k once it was landed in OZ. This included import fees, import tax, shipping, conversion, and of course, agents fees.)

That's why there are 100 TMEs here, + a handful of small volume imports.

 

What the Diameter of the tubing?? Do have outlet to go with it as well?

 

The internal diameter of the tubing is about 40mm.

What you see is all there is. Everything under there is going to be stock. I haven't taken off the heat shield yet to see what is next. It could go straight to the turbo, but I think there is one more collector or downpipe before that happens. Will let you know soon.

Hey, is it easy to take apart a turbo and put it back together? I thought since I already have all these grinding and polishing tools, and have the manifold off, I may as well polish the turbo housing. Does anyone know of instructions on how to pull apart a turbo?

 

I'm pretty sure they're there so that the manifold is homologated for Group N rally racing. I think the engine management is allowed to be changed, but parts like headers, turbos, and such have to remain stock. So Mitsu just made the manifold ALS-ready in its stock form.

1. That's not as big of a concern with turbo vehicles as it is with NA vehicles. The shorter the path from the port to the turbo the better because it gives the gas less expansion volume. Expansion uses up exhaust energy that could be used to turn the turbo. Equal length is desirable for its scavenging effects it can have. But the small gains you'll get from scavenging are greatly outstripped by the huge gains the turbo gives.

2. A lot of race teams make their headers this way. If done properly it shouldn't be much different from a single piece.

3. That sucks... hopefully you can get that junk with your dremel.

 

Ah! Cool!

Thanks Iodine. I don't feel so bad after all! Back to the salt mine! (My hands are now sore from gripping a wildly vibrating dremel going at 30,000rpm with a grinding stone!)

 

I've posted this link in another thread, here's where I got some of my information.

I'd be more worried about the pipes cracking at some point rather than worrying about losing power.

 

what turbo will you run with it? does anyone know if tubular manifolds are any better then stock?

 

I'm looking at HKS 3035S, or Garrett T3 Ball Bearing, but undecided. If stock turbo can bring me to my 220-250kw atw goal, then I might not upgrade at all.

But why did you automatically assume that just because I am replacing the manifold, I'd replace the turbo??
