Noddle Posted December 12, 2009 Author Share Posted December 12, 2009 Hi, I eventualy found a heap of buttweld pipes at my local Nubco shop ( http://www.nubco.com.au ), so I brought a 90 degree one I also drew up a flange for my 38mm Turbosmart wastegate I've uploaded it so if anyone want to get one cut they don't have to draw it up Nigel WasteGate Flange Finished.zip Quote Link to comment Share on other sites More sharing options...
speeder Posted December 12, 2009 Share Posted December 12, 2009 These adapters may work fine in lower boost/HP motors, but they have their limits and may not work as well in higher boost/HP motors. What is not desirable about these wastegate adapters is the 90 degree turn the exhaust gas has to make; especially as the speed of the exhaust increases, it becomes more and more difficult for the exhaust gas to make the turn. If you can manage it, a 45 degree angle or less is better. I have done wastegates on a downward facing pipe (used 1.75" thick wall cast iron from a hardware store, 42mm T'netics Racegate) welded to the bottom of an L28 manifold, and see no difference in quality of boost control at the 400whp level compared to this adaptor. Above that hp level for an L28 I have no experience. Quote Link to comment Share on other sites More sharing options...
J240ZTurbo Posted December 22, 2009 Share Posted December 22, 2009 Does anyone have a good picture or drawing on how this set up is? Quote Link to comment Share on other sites More sharing options...

Noddle Posted December 26, 2009 Author Share Posted December 26, 2009 From my research, these are some of the ways it can be done, these pictures have been sourced from a few sites, so I hope the owners don't mind me posting them Nigel Quote Link to comment Share on other sites More sharing options...

J240ZTurbo Posted December 28, 2009 Share Posted December 28, 2009 Im willing to pay who will like to do this job for me? I can ship my manifold with no problem. Quote Link to comment Share on other sites More sharing options...
J240ZTurbo Posted January 16, 2010 Share Posted January 16, 2010 does anyone have one of these already done and will like to sell? Quote Link to comment Share on other sites More sharing options...
J240ZTurbo Posted January 21, 2010 Share Posted January 21, 2010 can this adapter be weld with a mig welder with no issues? Quote Link to comment Share on other sites More sharing options...
hoov100 Posted January 22, 2010 Share Posted January 22, 2010 The bolt on adapters, you can buy off of ebay, the other one, I believe is custom. (I'm fairly sure you have to tig aluminum) Quote Link to comment Share on other sites More sharing options...
S130Z Posted January 22, 2010 Share Posted January 22, 2010 The bolt on adapters, you can buy off of ebay, the other one, I believe is custom. (I'm fairly sure you have to tig aluminum) Those "bolt on" adapters don't really "bolt on". You have to grind out the threads from the manifold side, then have the adapter welded to the manifold. This is because there is not enough clearence on the WG side(by the flange) to get a nut on the stud. Hoov, what peice of aluminum are you talking about? I was fairly sure aluminum was a no no for turbo manifolds . Quote Link to comment Share on other sites More sharing options...

As for the bolt on part, what would stop you from just running a long stud, that would go through the adapter? Quote Link to comment Share on other sites More sharing options...

My only problem was when trying to remove the studs, I snapped them off instead of removing them. Quote Link to comment Share on other sites More sharing options...

cockerstar Posted January 23, 2010 Share Posted January 23, 2010 Our manifolds are made of cast steel and not cast iron, so MIG welding on them is fairly straight forward. A proper preheat will help with penetration. I know BigPhill welded his adapter on without issue, but he wasn't happy with the performance on his higher boost application, iirc.

blairjj Posted January 23, 2010 Share Posted January 23, 2010 Howdy, I have one of the weld-on (bolt-on) adapters for sale in the classifieds. $45 shipped OBO. http://forums.hybridz.org/showthread.php?t=158718 Thanks, Jay Quote Link to comment Share on other sites More sharing options...
jeffp Posted February 8, 2010 Share Posted February 8, 2010 I just got done with this install. I neded to get a new manifold, as the SFP part rused very badly, and it would NOT stay flat. I started in on a stock manifold and worked the part extensively. The wastegate was changed to a TIAL 44mm part. I was able to get a 1 3/4" pipe in the bottom of the manifold, just under the turbo flange. I then routed directly to the downpipe. The install was not easy, but the pipe welded very well, and I was using 316L for the waste gate pipe. I was even able to get a 1 3/4" flex joint in the inlet side of the gate. I will have to post some pictures to my web page of the install. The manifold is out for JET-HOT 2000 (Black) and will be ready fo install after I get it ground flat. hat appears to be the weak point of the header, and I believe that is why they came up with the EURO header in three pieces.
