Aftermarket turbo exhaust manifold?

Bill, that sounds like good advice (put a turbo flange on a stock type exhaust manifold). Or maybe put a turbo flange on each half of Dutra Duals. But I gotta know, where's the Aussie turbo header from? These pics, are they the Aussie header or your own? If they're your own, I'm completely impressed; that's some terrific craftsmanship. Looks like an O2S port at the turbo flange...but what's the 2-bolt flange connection facing the sky for? Intake heat...?

Thanks for the kind words!!!!

I'll have to do a search to find the website that offered the Aussie turbo headers; can't remember,now.... but they had pictures.

The pictures in my last note are of the header that my racing partner (Freddie Nielsen) constructed BY HIMSELF,this summer, at age 72, after never having built a header in his life. That is the only one. Maybe he missed his calling,huh? NINE people have I-M'd me wanting a copy of that header,but Freddie says "never again"... He has a pacemaker and a defibrilator in his chest and cannot weld, (R F) so, he had to use adhesive tape to tape the pieces together 'til we could get a friend who CAN weld, to stop by and spot weld them togewther, so we could take them toa weld shop and get them T.I.G-welded. We probably could have gotten them M.I.G-welded, 'cause they're just mild steel, but we thought T.I.G. looked a little better. Then, we took them to a shop that does ceramic coating and had them done in a chrome-looking finish.

I think ol' Freddie did himself proud (I never touched them) for a first-ever effort. I wish I could take credit for them, but he did it all...

The vertical standpipe you asked about is there to mount an external wastegate to control boost levels. The hole we put in the collector, next to the wastegate standpipe, is for a F.A.S.T. oxygen sensor probe bung, and in my ignorance, was located in the WRONG place! It needs to be on the other side (downstream) of the turbo. It will overheat in the present location and come apart, and end up in the turbo blades.... DUH! We'll plug that hole and reattach the probe bung in the downpipe, downstream from the turbo. Beginner's luck.... Never built a turbo ANYTHING before,much less a /6...

Here are some more pix of that header... and one of the '64 Valiant 4-door that engine and 904 is going into.

Thanks for your interest, Dan!
