RJC DP FlangeRJC-3DP-EXWG: This DP flange (pictured Left) is made from 1/2″ thick 304 Stainless Steel. It is for the guys that prefer to run external style Waste gates. It will accommodate 3, 3.5 or 4″ pipes and will fit Q trim turbine wheels. Makes fabbing up a down pipe a snap.

Price; $55.00

 

 

RJC DPBOP FlangeRJC-DPBOP: This is designed for the guys that prefer to run the external style waste gates with internal waste gate down pipes. This 1/8″ thick 304 stainless block off plate adequately seals off the factory waste gate hole. The block off plate will work with any style DP including our massive 5″er. Some guys use this when they port out their waste gate hole to big and the puck does not cover the hole. You can use this and redrill the WG hole in the plate smaller and in the correct place to economicaly fix your turbine housing. If you have one of our down pipes we have a plate that has the hole already drilled in the correct place and the correct size so all you have to do is sandwich it between the turbine housing and DP flange and you are done.

Large Waste Gate AssemblyRJC-WGA-L. Pictured on the bottom, New Massive 1.625″ puck. This new puck was made specifically to control the new billet wheel turbos with the stock style waste gate actuators. This will easily control even the largest most powerful 71 CEA billet turbos. Just like our standard 1.375″ puck (pictured on top) this is made from all 304 Stainless Steel. This assy is now standard in our 5″  and  3″ down pipe. This can be purchased separately or with our flange pictured above. If you have previously purchased one of our down pipes this puck is a direct replacement as the flange was designed to accommodate this large of puck. very easy install. only one weld needed to install. All that is required to install this new assembly is a 1/2″ hole in the WG flange and one weld.

In the picture, the top flange shows our standard 1.375″ Waste Gate puck next to a quarter for reference. the lower flange showcases our large 1.625″ Waste Gate assy. As you can see the Large puck is massive in size (that is a quarter in the top flange) and fits easily in the flange.
