evo3 exhaust manifold

[Andrew Dahms]

I just bought an evo3 exhaust manifold and after bolting the manifold to the turbo I found that there is about an inch between the manifold and the head. The website I ordered this from assures me that it is ok to tighten the exhaust nuts to pull the 2 surfaces together, but this is my dd and I cant afford to pull the studs out of the head or some such thing. Is its actually ok to do this?

You should be able to close that gap by pushing the manifold flush against the head with your hands.
As long as nothing is in the way and the manifold is not a bad piece, you shouldn't break anything by tightening the nuts to close the gap. I have done it for heavier things such as transmissions.

So what do you think is holding it back?
Figure that out first before you put any pressure or you may be very sorry.
It should easily sit flush with the head so either something is in the way or your water/oil feedlines are holding it away from the head.

Like olmytsi said you should be able to just push the assembly flush with the head. If you are unable to push them together then something is blocking it, and that will need to be fixed before you can continue.

Damn I got beat to it.

Did you get the turbochargers.com gt manifold?

Because I own that one and it did not bolt right up. You have to literally dremel down the right side of the manifold corner and/ or the lower part of the power steering bracket because it was improperly measured when in production or something.

I had about a inch gap on mines also where even when I thought it was all the way against the head it still wasnt and there was a huge exhaust leak back there and it sounded horrible and I ran like that for like a week almost. So look into what im talking about , because I dont have any pics to better show you.

The manifold is great, with a great price except for that one idiotic flaw.

No this was the actual evo3 manifold from SBR though I also took an angle grinder to the right side so it would move up. I think you may not have understood me, if the turbo bolts arent in place I can freely push the manifold against the head but then the bolt holes in the manifold dont like up with the bolt holes in the turbo. Its as if the manifolds runners are an inch too short.

Good to know that the manifold by itself will go flush so now you need to figure out what's holding you up like I said above.
Unless you have some non-stock turbo everything should clear. You haven't said if you trying to use something othr than a stockish turbo.

I have an evo3 16g

 

[steve]

Then you shouldn't be having a problem. Check to see if you got something between the turbo and the block/water pipe that shouldn't be there or if you bent the oil/water lines and are trying to bent them back.

As long as they are both geniune parts you should have no problem getting them both to line up. First you should be able to slide the manifold right up flush to the head and an evo 16g should lift right up to the bolt holes in the manifold. I have ran that exact combo before and everything should clear just fine. Make sure there are no water or oil lines being snagged. It is said that some grinding may need to be done to clear the power steering bracket but mine cleared that great. Maybe for a 2g but not sure.

What he said. 2G doesn't have the issue, 1G does. It should have been obvious that the manifold is catching against the PS bracket. Forcing it down is not advisable.

My 1G needed no grinding either. . . Nothing. just a good OEM fit. . .

The part that sticks out to me is "I can freely push the manifold against the head but then the bolt holes in the manifold dont like up with the bolt holes in the turbo."

I'm going to assume the turbo is in the car with all oil and coolant lines attached. The turbo is going to have to be pushed up/back into place to get the bolt holes to line up perfectly. Have you attempted to push/shove the turbo back far enough to get the bolt holes to line up? And after you have done that if they don't come close to lining up having someone else push or look for why your turbo can't be pushed back far enough.
