violacleff Posted September 3, 2004 Share Posted September 3, 2004 I'm putting my IC plumbing together and it looks like I may have to take off the turbo to weld on this 90" bend. I took some pics of it. Could you tell me if it would be possible to weld this piece on without taking off the intake manifold or turbo? Second question. If I were to use silicone to connect it, would it be pretty safe at high boost provided I'm using the best grade silicone (which I am) beaded ends and t-clamps? I would rather do that than take this stuff off again as I'm sure I can't reuse the manifold gasket after having torqued the bolts down. Oh yeah, that brings me to a third question. Does anyone make a metal exhaust manifold gasket? and how hard would that be to frabricate ( for an experienced fabricator)? Here are the pics I took of the Turbo/ 90' bend Dave http://photos.yahoo.com/d__minus Quote Link to comment Share on other sites More sharing options...
yo2001 Posted September 3, 2004 Share Posted September 3, 2004 To hold the hose, good ol' Walmart Aquanest hair spray does the trick. Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted September 3, 2004 Share Posted September 3, 2004 Why do you think you need to weld on the coled side, and make the turbo more unwieldy to handle? If it is a matter of adapting from the outlet of the turbo to the 90 degree bend use an appropriate coupler. Quote Link to comment Share on other sites More sharing options...
Supra510 Posted September 3, 2004 Share Posted September 3, 2004 Silicon hose will work fine. If it's really close to the exhaust manifold and that is your worry then wrap it in Thermotec heat shield. I would not go to the trouble of welding that.

240Z Turbo Posted September 3, 2004 Share Posted September 3, 2004 Just undo the 6 bolts that hold on the compressor housing and take it off. You can then safely weld it. Quote Link to comment Share on other sites More sharing options...
Clifton Posted September 3, 2004 Share Posted September 3, 2004 Just undo the 6 bolts that hold on the compressor housing and take it off. You can then safely weld it. That's what I did on mine. One little peice of slag will ruin your day. If you have the room which it looks like you do just hose clamp it. I am running a metal T4 gasket. They have a bead that crushes a little to seal so I don't think you could just make one unless it was from a soft copper. If the 2 surfaces are flat you don't need to run a gasket, I don't with the GN turbo on my truck. Quote Link to comment Share on other sites More sharing options...
violacleff Posted September 3, 2004 Author Share Posted September 3, 2004 Thanks for the reply. The only reason I was going to weld it was because I was told to use the least amount of silicone as possible. But if a good coupler will work, then I rather go with that, and use a heat shield to protect it. Speaking of the heat shield, I have seen to types: the wrap, and the Stainless hard one. Is there a difference for the use of these and which would you recommend? Quote Link to comment Share on other sites More sharing options...
