Okay so I wanna get everyone's opinion here. I currently have an internally wastegated ebay manifold for my 2.2 ecotec turbo build.

Here is where I am, I want to go with an externally wastegated turbo and setup. Obviously this is a problem with an INT WG mani. So, should I just have an exhaust shop weld a v 2 bolt flange or should I go with one if these?

I'm looking for the best bang for my buck.

You drive a cavalier? Why yes... yes I do.

In my option the RD Fabs manifold is going to be the highest quality and should come with a lifetime guarantee on the work(if a weld cracks they'll repair it for free).

Ya I was leaning towards the RD fabs one. But the $700 is a lot to spend lol. I guess I better save up some more.

Has anyone ran one of these? If so, how much boost?
