Guest Anonymous Posted May 6, 2002 Share Posted May 6, 2002 Hi all, I have been looking through some sites and I have seen some really nice exhaust headers that were custom made! And I was thinking to myself that I could make me one too . Does anyone on here have AutoCAD experince? Or does anyone know where I can get some more info as too building my own header? It will be for turbo a application. Its going into a 78 280z. Thanks for your help!!! Russell Quote Link to comment Share on other sites More sharing options...

Dp351zcar Posted May 7, 2002 Share Posted May 7, 2002 grumpy posted a good reply to someone else who wanted to do this also. Search for it, it was a very good idea and one I had not heard of before(boy thats never happened before) it was good reading. Don Quote Link to comment Share on other sites More sharing options...
katman Posted May 8, 2002 Share Posted May 8, 2002 The headersbyed website has lots of good info about headers for normally aspirated American V8 engines, and generally good design tips. However, for a turbo application all bets are off. Corky Bell at Bell Engineering (used to be Cartech)would probably be the most knowledgeable about a L6 turbo header, but his time isn't free. Fortunately the exhaust system for a turbo setup isn't near as critical as for N/A (just turn up the boost screw, Bubba), and you can make godawful amounts of power with the stock 280ZX manifold. I don't see where AutoCad would help, CATIA maybe. I know AutoCad but it won't help you decide what primary lengths and sizes etc. you need, and its really faster to mock them up with flexible tubes than to draw them up in a 3D package like CATIA, at least for me. Might help you draw the flanges etc. so you could have a machine shop make them. Headersbyed and Stahl and others sell collectors and tubing, etc., and Stahl makes a reasonably priced head flange for Z's as a starting point. Personally I'd spend my time and money elsewhere for a single turbo setup, like in the fuel management. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted May 11, 2002 Share Posted May 11, 2002 Thanks to all who responed I was just trying to get some ideas.

Guest Anonymous Posted May 12, 2002 Share Posted May 12, 2002 Russell, do a quick search through the turbo section, I remember a while back (circa.. december.. ) someone posted a good site on designing some home turbo headers from weld-els. I thought it would be an interesting thing to try (I personally don't care too much for the moderately pulse-imbalanced stock turbo manifold, but that's another story).. however I don't have much experience in welding anything but scrap metal, and it costs gobs of money to have people make custom headers. If I find the post I'll put a link here. -980mak Quote Link to comment Share on other sites More sharing options...
