Well I started getting in my turbo and parts and this flange was with it. I am guessing it is to run the waste gate rather than just y-ing in a pipe and off of it. It was free with my turbo so no complaints. With a t-76 what size do I need and anything special to run this plate. Looks like it wasnt cheap so hope it can be used. If you have this set up and know exactly what to do that would be great or just if you are familiar with it. I am no on a ebay budget as I am out of work for the moment and still trying to get this all done. Headers are built and starting the rest of the pipe today but wanted to know what to do with this and if any one knows of a budget waste gate I can use and the size needed. I cant afford a 200 dollar one right now and if have to will get a cheapy and replace it asap with a good one or if any one here has one used for a good price. I dont even know what size I need for this set up. Looking for more good advice from you guys here.
