I bought a set of C6 LS2 exhaust manifolds off of Ebay to use one on my passenger side for the turbo plumbing. My first question is what do I plug these holes with (I am assuming it is for an O2 sensor or something)?

Secondly, where can I get a two bolt flange for this to weld to my plumbing? The spacing of the two bolts center-to-center is ~ 4 3/8".

Thanks!

they are for your o2 sensors

Hmm...seems like unusual placement, but ok.

Measure the distance cen to cen on the bolt holes, i have 2 flanges sitting at home that might work.

It's ~ 4 3/8"

so, just put a cut down bolt in that hole and call it a day. thats what i did. i cut it down because I couldnt find that bolt in the correct length.

I got custom made flanges from smi fab

they were like 40 bucks shipped for the pair, and he can make them with any size hole you want.

I'm going the c6/truck manifold route. But I plan on hacking the flanges off and going with some vband clamps.

Interesting - it doesn't look like there is much to hack off on these.

If it comes down to it I'll probably just keep the flange on the c6 manifold.

Is there a problem with where these o2 bungs are at? I mean they obviously work for the Corvettes from which they came, it just puts the o2 sensor much closer to the exhaust ports on the head than I recall seeing before.

I'm interested to see what happens with these manifolds as they just might do the trick for my build!

plug them, run open loop

I am using these for my Datsun 280ZX ls1 turbo build. I used 2 left side manifolds for mine though. One points forward and the other points backwards. Both are facing up though.

Why two passenger manifolds? I wondered if they would work turned upward in an fbody since they seem to be more compact, but I had doubts about clearance, especially with an SS hood. With the engine out of the car, it makes it even harder to gauge.

Looks like a sweet setup!

In my car the RH manifold flipped upsided down and pointing forward on the passenger side it was too close to my strut tower. I debated notching the tower but I didn't really like the idead of cutting metal out to make it fit. This worked much better for me. They are deffinetly a compact design.

here is my c6 setup

Yeah, I'm thinking about using both the C6 manifolds now instead of just the one on the passenger side with a truck manifold on the driver's side. They're brand new and purdy lookin'.
