I ordered a flange from ATP, it said T3 w/ internal gate. Well I got it today and got all excited about build my 3" dp and ends up the flange does not fit. In inner diameter is right, but the three holes for the studs are too small. When I say too small I mean too small for the studs on the turbo and too close to the center to line up anyways. I don't get it! Anyone know what type of flange I need? I'm tring to get the car back together for the GR meet this weekend.

This is the one I got.

Derek, the Super series exhaust housing uses a T3 inlet but not the outlet. It's a 3-bolt but I do not know what the specifications for it are. It's on HRCs website ... H TZ-7180 ... http://www.hahnracecraft.com/hahn/parts/install.htm. I'm sure they can get one out to you.

Hey Derek. I got it and the hose. Thanks. It's been busy so I haven't had too much time these past couple of weeks.

This flange, right?

It's a standard 2.5" domestic header collector flange on the S16G. Not sure if the S25G uses the same flange... Any ford/chevy shop should carry it though.

Ah shit, I already ordered it. I didn't know it was a std flange, I would have picked one up at an exhaust shop! Damn!! Oh well, it's on it's way now.

meh, the HRC flange is a good quality flange, so you're probably better off getting theirs anyways.

its just a standard 3 bolt v8 header flange
