Its a 400+ whp turbo, it'll bolt on with the included dejon adapters.
Here's a dyno of the dejon kit on a solstice gxp, i believe the engine had some internal work done, no clue on the boost setting.

Hate to break it to you, but someone is lying. That dyno graph is mathematically impossible. So either that dyno is software is all screwed up, or someone altered the graph.

I believe I am the only cobalt to have this kit. It has been passed down from boosting to fface and eventually to me. Let me start by saying you can hit 400 whp. Now with that in mind, the stock manifold sucks with this turbo. Actually the stock manifold should not be used with anything except the stock turbo. The stock manifold is setup for a twin scroll turbo and will not flow that well with a single scroll turbo. It simply does not flow down low. The turbo will start to spool around 2500 rpms but won't hit full spool until 5000 rpms. Once it gets to 5000 rpms tho it flat out goes. Anyway I am ordering a new log manifold from Vulcan turbo.

Uhh, is no one else noticing that the torque and hp curves are crossing over in the wrong place? Not possible.

Something is fishy about that graph, no doubt about it. Also, your name is censored when we quote it, lol. I guess that the new site owners don't want us to talk about ass and wang.

Hahahah. Too funny about the censoring of my name. I've noticed that the new owners of the board of some pretty absurd censor rules on. I mean, ffs, it's my last name.

You shouldn't push more than 25 on the stock turbo... really 22-23 is the limit.

No. Not possible.

HP = Torque x RPM ÷ 5252

Which means the torque and hp curves must cross at 5252 rpm for any engine/motor.
