lookforjoe Posted November 13, 2014 Author Report Share Posted November 13, 2014 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. Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted November 13, 2014 Author Report Share Posted November 13, 2014 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 1 Quote Link to comment Share on other sites More sharing options...

lookforjoe Posted November 13, 2014 Author Report Share Posted November 13, 2014 eeek! Good god. How many miles? I don't remember exactly when I installed it - it was on my old engine / hybrid 20g setup, so around 40k & a few years. Not a long time, in other words.

lookforjoe Posted November 14, 2014 Author Report Share Posted November 14, 2014 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 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 :) 3 1 Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted November 14, 2014 Author Report Share Posted November 14, 2014 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. 1 Quote Link to comment Share on other sites More sharing options...
Mesoam Posted November 14, 2014 Report Share Posted November 14, 2014 Collector rust & cracks :blink: I do wonder if having the manifold ceramic coated would have preserved it? Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted November 14, 2014 Author Report Share Posted November 14, 2014 :blink: 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.

lookforjoe Posted November 15, 2014 Author Report Share Posted November 15, 2014 Removed the SS braiding layer from the coupler - with that, the coupler fits between the firewall & swaybar. clearance going down 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. 2 Quote Link to comment Share on other sites More sharing options...
seaofcortez Posted November 15, 2014 Report Share Posted November 15, 2014 Are you going to dump the wastegate to atmosphere or plumb it back into the exhaust again? Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted November 15, 2014 Author Report Share Posted November 15, 2014 Are you going to dump the wastegate to atmosphere or plumb it back into the exhaust again? No screamer pipe. The last couple of pics covered my WG dump options Quote Link to comment Share on other sites More sharing options...
