Butt welded

And no cracking issues? That's good - so I'll do the same with mine - SS pipe is not forgiving if you try to expand it..

I am going to make a support under the hotside - I should be able to make a tension mount that pushes up from the angle drive to fully support the weight of the turbo. That should ensure that when the header is expanding/contracting it's not dealing with all that weight hanging.

Collector rust & cracks

Pretty sure they ground down a fair bit to tailor the flow on the inside, perhaps they just went too far.

Header is moving on to a new home :)

Got the EGT and EBP bungs welded in place

Tomorrow I need to get this all test fit so I can mock up the new DP

Test fit the manifold & turbo.

With production variations/tolerances the new header pushes the coldside firmly into the heat shield.

DP is cut from SS mandrel bend

Firewall / swaybar clearance without 3" ID flex coupler

A1DF2467-D8C7-4A28-BE80-52B15296E75F_zps

Have to figure out if there is any way to make a modified flex coupler between the DP & WG dump. I have a flex coupler at the base of the DP where it runs back, I think I'm gonna leave it at that. Otherwise, the coupler will be wedged between firewall & swaybar like before, and servicing / removing DP in one piece with that in place is not an option. Welding SS is like butter compared to aluminum :)

I'm going to try removing the outer braid layer of the couplings - that will reduce the OD by enough that it should fit. I bought them through MandrelBend & the tech there didn't think that removing the braid would drastically impact the longevity of the coupler. OEM ones don't have it, so I'm hoping for the best. Both DP & WG couplers are the interlocking SS liner style, not the cheap braided inners. Lars has stressed that you really need the flex coupler in the DP, so that's the way I will try to work it.

I do wonder if having the manifold ceramic coated would have preserved it?

I would assume so - my X1/9 headers are ceramic coated, and even though they fucked up around the flange and the collector, it's still in one piece after more years than this one, and that sits around unused much more.

Removed the SS braiding layer from the coupler - with that, the coupler fits between the firewall & swaybar.

Removed the header. turbo & DP so I can now fabricate the coupler for the WG dump

no way to fit a flex coupler unless I remove the braiding & cut it down to just a few inches

May just go with a rigid junction

Have to weld the O2 bungs in place also, and redo the straight pipe back to the resonator in SS pipe also.
