Ruiz Racing Posted February 21, 2011 Share Posted February 21, 2011 I want to build a custom down pipe for my 1981 280zx. I need a flange that will fit the stock turbo. Does anyone have a flange for sale? Or know where to get one? Quote Link to comment Share on other sites More sharing options...

Does anyone have a flange for sale? Or know where to get one? Ebay. Should be a 4 bolt T3 flange with 2.5" ID. Quote Link to comment Share on other sites More sharing options...
aarang Posted February 21, 2011 Share Posted February 21, 2011 Cutting the one off the stock downpipe is the easiest way to do it. Quote Link to comment Share on other sites More sharing options...
Ruiz Racing Posted February 21, 2011 Author Share Posted February 21, 2011 Ebay. Should be a 4 bolt T3 flange with 2.5" ID. That was my first thought. The bolts are off set. A universal 4 bolt flange will not work. Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted February 24, 2011 Share Posted February 24, 2011 (edited) I got a 1/4 inch piece of steel plate, burned a hole with a torch to slightly smaller than needed, drilled the bolt holes, and then touched up the large burnt hole to match the gasket. Then I used a bench grinder to do the final shaping. Edited February 24, 2011 by HowlerMonkey Quote Link to comment Share on other sites More sharing options...
Ruiz Racing Posted February 25, 2011 Author Share Posted February 25, 2011 That's my plan now. I met a friend that is going to make one for me. Quote Link to comment Share on other sites More sharing options...
bluezx Posted February 25, 2011 Share Posted February 25, 2011 Adam 78280z has some listed in the vendors forum for $20.00 shipped from F.L. Check out his post. Looks good and the price is right. Mark. Quote Link to comment Share on other sites More sharing options...
