IAT install

I'm assuming that the ETS kit is made of steel piping but the bung is aluminum. What did you do to resolve issue. I'm just looking for the best option. Did you buy a mild steel bung, or was there another option solution?

Hmm, yea your gonna need a steel bung. Not sure bout the IAT but I have used a nut that is the appropriate thread pitch from a hardware store for a o2 before, kind of ghetto I know. One thing to consider with this method though is that you need to find a shallow nut so the sensor isn't covered.

I had Andre weld a stainless bung onto my piping for it. But before that, just to get me by, I drilled and tapped a hole in the piping myself. Worked just fine.

If it's a GM IAT just get an O2 bung from any exhaust shop and use that. That's what I used for mine. After it's welded you can go in with a die grinder and smooth it out.

I would drill and tap but then it would be an obstruction in the flow, I assume. Thanks Mark, I was in a bit of a hurry to get the car ready for a local meet, but not worth f***ing up somewhere. Just going to do it right the first time and avoid the hassle.

fwiw
SS bung

Perfect.

I have mine mounted so the actual sensor tip sits about 1/8"-1/4" into the pipe. You don't want it too shallow or you could pick slightly skewed temp readings from the pipe when you go from idle to drive and back to idle. Was told this by ecmlink forum a while back. Only a small issue with SS or steel piping.

I finalized the setup for SD on link. Turned over the engine w/o fuel, just to get the oil circulating. I reconnected the fuse for the wally, and speed density start up was successful. I have an two issues though, I have to get a new o2 to dp exhaust gasket, which is easy. The kicker is, should I take the catalytic converter out. Is there significant reason to cut it out? It's a catco 3". Emissions inspection is not an issue, I just want to know if I should spend money to cut it out and reweld some pipe in its place.

Do you want to help the enviroment a little more? It's really your decision. You will some gain power, but modern High-Flow Cats don't restrict quite as bad as you think. You might be losing 20hp, or so maybe. You can easily make that up with a little more boost. I currently don't with my 16G and 2.5" exhaust, but when I build my 3" I'll be adding a cat.

Glad your running SD, It's great when you blow a coupler during a pull miles from home. /ubbthreads/images/graemlins/grin.gif
