xxjoeyxxeb Posted May 15, 2009 Share Posted May 15, 2009 Hey guys, I just bought 3" piping to build my exhaust for my turbo swap into my 74 260z. I want to build it up to the turbo outlet and was searching for flanges but there was only 1 post that showed a place in New Zealand that may have had the flange needed. I was wondering if this looks like it will work, I e-mailed them for dimensions but they forwarded me to another company who I haven't heard from yet. http://www.racepartsolutions.com/products.asp?cat=105&pg=3 It's at the bottom of the page. T3 Turbo Discharge Flange. I was thinking I can get that, or a correct one, then a 2.5" - 3" expander. Any help would be great, and I'll keep searching in the meantime. Hoping to buy it today so I can have it by next weekend. Thanks, Joe Quote Link to comment Share on other sites More sharing options...
xxjoeyxxeb Posted May 16, 2009 Author Share Posted May 16, 2009 No one has bought a flange when building their own exhaust? I know Warren made some but that was long ago. I got 1 company to write me back but it wasn't correct size. Quote Link to comment Share on other sites More sharing options...

xxjoeyxxeb Posted May 16, 2009 Author Share Posted May 16, 2009 Thank you, I just sent them e-mails for dimensions. The first one from Ebay gave me dimensions of a 3" bolt spacing and a 4" diagonal bolt spacing, which was definitely wrong and the picture matches most of the ones on the websites so I'm assuming they are wrong also. Hopefully one company has some good dimensions, or hopefully someone here has a part number of a successful flange they used. Thanks for more leads!

xxjoeyxxeb Posted May 16, 2009 Author Share Posted May 16, 2009 I keep finding a lot of 90deg bolt patterns. Quote Link to comment Share on other sites More sharing options...
cockerstar Posted May 16, 2009 Share Posted May 16, 2009 Are you using the stock Nissan turbo? It has a unique 5-bolt pattern that you won't be able to find a flange for. Quote Link to comment Share on other sites More sharing options...
xxjoeyxxeb Posted May 16, 2009 Author Share Posted May 16, 2009 The stock downpipe definitely bolts up to the turbo with a 4-bolt pattern. Quote Link to comment Share on other sites More sharing options...
cockerstar Posted May 16, 2009 Share Posted May 16, 2009 Sorry Joey! I don't know what I was thinking. The center section of the turbo has a unique 5 bolt pattern. You could always go down to a local machine shop and have one made. It's a fairly straight-forward piece and shouldn't be too expensive.

xxjoeyxxeb Posted May 16, 2009 Author Share Posted May 16, 2009 It ok, don't worry about it. Ya, I was thinking about trying to find some scrap metal and have some guys at the shop I work at try to make me something. Or draw a part up and get some made then sell them here or something.

Warren Posted May 16, 2009 Share Posted May 16, 2009 Inside diameter 2.25"...go from there. Here's a post about the ones I made and have no more of. http://forums.hybridz.org/showthread.php?t=128111 Quote Link to comment Share on other sites More sharing options...
bobbyc Posted May 20, 2009 Share Posted May 20, 2009 if you have a buddy with a drill press you can make your own easy. i made one out of 1/4" plate a few years back...worked great with no problems. just use the gasket as a flange. Quote Link to comment Share on other sites More sharing options...
xxjoeyxxeb Posted May 20, 2009 Author Share Posted May 20, 2009 howd you cut out a 2.25" hole? Quote Link to comment Share on other sites More sharing options...
bobbyc Posted May 23, 2009 Share Posted May 23, 2009 with a hole drill bit....designed for metal...just slow down the speed and use wd40. Quote Link to comment Share on other sites More sharing options...
jeffp Posted August 7, 2009 Share Posted August 7, 2009 I just did a T3 inlet flange in 304. Not to bad to do, I used a conventional mill for the work. I did spend some time on the part. I am working on the outlet for the GT35R turbo. The four bolt outlet. I first bought a mild steel part, but it has rusrted to much for me in a short amount of time, so I will do this part as well. BUT, I bought a piece of 5" 304 round stock, 2' long and that ran me 100.00 for the material just to begin. I priced out a number of metal places one place had the dia I wanted, but they could not tell me the type of stainless steel. They mentioned 303, and that will rust. I decided to start with known material and that is what it cost the cheapest I could get the stock. Quote Link to comment Share on other sites More sharing options...
jeffp Posted August 7, 2009 Share Posted August 7, 2009 if you start to do your own parts, then before you buy stocked materials, look at the scrap racks for the material you want. I have gotten most all of my materials that way at a significantly reduced cost. If I had been sure of the type material today, I could have gotted a 6" long piece for 50.00 As it stands now, they are cutting a piece for me, and as I found out today, a 5" piece of round stock is hard to come by. 316L is really what I wanted, but the only company that had it wanted 214.00 for a 2" long piece of material. This stuff can be quite expensive, and I am guessing this is why I can not find the part in SS, because of the total cost to buy. Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted August 7, 2009 Share Posted August 7, 2009 I use a cutting torch to make a hole slightly small and then a die grinder to size and shape it. Sure...you end up with super sharp splinters of metal all over your clothing but it can be done quickly with only three tools (vise or vise grips, torch, and die grinder) Paying 15 to 25 bucks for one already made saves you the hassle of pulling metal splinters from your socks a month later.
