if hes gutting the supercharger, and just gonna tap into it via the turbo...then the pressure sensor wouldnt matter since its before the supercharger.
even so, you can disable it with hptuners.

I am going to say Yes. Although this kit is marketed for the 2.2, it will bolt up to the 2.4.
The difference between a 2.2 settup, and the 2.4 settup is nothing. the 2.4 just has more displacement.
The blocks are the same size, the layout/everything in the engine bay is identical.

There are a number of people wanting to use this kit on either a 2.4 or an auto. It will work, but with the following differences;
On the 2.4, you will have to use HP Tuners. Not a big deal actually. In fact, you guys already have the necessary tuning tools that the 2.2 is still waiting for.
If you are putting in on an auto, there are two issues. First, if you read the installation instructions for the kit, it has you install the oil return in the cast-in dimple on the side of the engine block lower girdle. You can't do that with the auto because the transmission is in the way. You would have to install the return in the oil pan. Not a big deal since you have to remove the oil pan either way. It's easier actually, because you will have the oil pan off and can do the job on the bench.
Second, you need to be able to tune your transmission as well as your engine. Again, for the 2.4 guys, your set with HPT, because they support trans tuning as well.
--------------------------
Now I have a question. The kit is sold with the GT2860RS. I want the GT2871. Can you get the kits with a different turbo right from the start? Or do I have to buy it separately?

The GT2860RS can hold a 2-1 pressure ratio (15 psi boost) at 25 lbs/min. Good for anything up to 250 HP on this engine. The GT2871 can hold a ratio of 2.5 (22 psi boost) to 35 lbs/min. Good for up to 400 HP.
Garrett states the kit is designed to deliver just over 200 HP, so its probably set at around 7 psi. You can turn up the boost, but would need to tune it. This set up would make for a very fast spool time, so the car would have a peppy acceleration. If you turned up boost much past 15 psi however, you will run out of air at the top end. Still, you are efficient to around 250 HP, which is pretty damn good.
With the bigger turbo, you sacrifice a bit of that quick acceleration, but now you make a ton of power. It's really only necessary with a built engine that can handle it. I might very well start with the GT2860 and max it out first to see how the car handles before I swap up to the GT2871.

They are same basic design, so they should both last the same. Durability really isn't an issue. They are ball bearing units with oil and water cooling. They should last forever.

Actually, neither. Hahn is probably going to retail the Garrett kit in leiu of selling their own. Its still up in the air pending the successful outcome of tuning from SCT. I don't even have any really solid plans yet. I will probably do a bit of hybriding. I want to use the Garrett manifold, turbo, downpipe and charge plumbing. I want the Hahn intercooler and Sheetmetal intake manifold, and Exhaust system. And then ofcourse a flash tuner from whoever gets one made first!

The turbo really isn't big enough to warrant the need for an external gate. Internal gateing is a nice, compact option, fewer parts, and works great for our 4 cylinder applications. Plus the Garrett and Hahn designs are really simple.
