Aftermarket EA82T Manifold
Well, unfortunately I am without a scanner at the moment, as we just moved, but I took some photos of my photos from about 8years ago, when I made a set. They were made out of 2 1/4" mild, press bent, as mandrel bends were unherd of in my lil' town. It made such a huge difference, as did the ones I made for my EJ20TT. Headers are the place to start on a turbo in my opinion.

Very nice!
What ever happened to it?

I found a couple of good threads at USMB but can't access that site from this "foreign computer" .
There are differing opinions on pipe size and some think the TWE's healthy tubes are fine .
From what people say the small inner tube diameters on the factory appear to be ~ the 1 1/4 to 1 3/8" size (33-37mm) .
I guess I'll have to sit down and work out the cross sectional areas to have a handle on the various tube diameters vs area .
What makes it hard is the two adjacent cylinders sharing the same port and engine pipe and trying to work out an ideal tube ID .
There is a possibility that the Techworks header gets away with slightly larger diameter tubes by having the two engine pipes merge just below the turbos mounting flange .
The downside is having two tubes feeding up through the hole in the cross member and avoiding things like power steering lines .
It would be a pain but if a header was fabbed with flange joints before the collector the engine pipes could be made in an alternate size if the first attemp wasn't right . I was thinking along the lines of flange plates like my old Bluebird used to have to join its twin down pipes off the bottom of its cast iron exhaust manifold , three nuts and bolts could hold it together and it would mean the engines pipes could be individually removed to fix blown gaskets or to remove a head without pulling the whole header . Could possibly unbolt it and remove the turbo upwards complete with the detached collector .
Thoughts ?
