Wich gen exhaust/turbo manifold do I have?

[turboimports]

Sorry all.
But I'm trying to find out what exhaust/turbo manifold I have.
Is there anyway I can tell by just looking? There has got to be a way.
I remember something about the different studs, but can't recall off of my head at the moment.
Any help is greatly appreciated.

Thanks.

Look at the # 1 runner (by the PS pump)

2G: (the one on the left, the right one is an upgrade from FP)


1G: Don't be confused by the extra holes, it's been modified to fit a honda F22 head.

On a 2g manifold the holes for the bolts will be flush with the runners since the manifold has more curve to it and the holes on the 1g manifold will stick up a bit since the 1g is more of a flat design. Also the 2 most outer holes will be bigger on the 2g mani.

You can see what I'm talking about with the manifold to turbo bolt holes in Ryan's pics. Although I'm not sure what's going on with the manifold to head holes on the 1g mani.. Those usually wont look like that. haha

Thanks all.
I think the 1g manifold is someones Honda project.

The easiest way to tell a 1g mani from a 2g mani is to look at the number 1 runner. On a 2g, it will have a raised "ring" (as I call it) and the 1g mani will just be smooth from the head to the collector.

I usually just look at the holes for the turbo as someone already said. The 1G ones stick up, and the 2G ones are flush/indented.

2nd the raised ring, thats how i tell!

Just as a side question, how do you tell the difference between a 2g and an Evo 3 exhaust manifold?

[turboimports]

I have the 2nd gen manifold.
Looks like the beater is going to get more breathing room once I port it and swap it in.
Alright, I'm set for the moment.
