is this better than our stock downpipe flange?

I don't think it'll work. Or it'll be close. The bolt pattern looks and should be the same, but where the two bolts are that are closest together, below the wastegate - our turbine housing is shaped differently. It doesn't bow-inwards in that semicircle shape between the bolts, it runs straight between them. I dunno if his flange will seal in that area.

i'd think not... it kind of restricts flow... but then again... if the turbo is jetting a straight thru blast.....

this is the stock one next to the gt2871r that people have been bolting up to our flange. I never noticed that difference in the shape though, hmmm. I might consider building a complete downpipe if I wanted a good seal on my ball bearing turbo anyway. I will probably build two downpipes now actually. one for my ball bearing one and one for journal bearing style with the modified stock flange.

I bought a T25/28 flange that had both bolt patterns in it did not seal at the side. I had to fill it with weld and file flat to cover, then grind out the inside for flow. It did bolt up correctly, but the shape did not match our turbo.

 

Good luck with yours.
