The 67 is a gtx compressor wheel. It's newer technology and better overall. Personally I'd do a 3067, but that's just me.
Yeah i noticed is the gtx model. I was actually going to do a 3067, that was my original plan with a twin scroll housing and manifold. Im building a a gen4 and i really trying to keep the best low end as possible. But i got a crazy deal on a v band tial .86 housing for gt28 so i will just use this for now, and might just go with the 2867, but i also was kinda leaning with the 2871 because the offered a 4" inlet with 2.5" out compressor that would of been nice.
