Adding a turbo to a 2.4

So I’ve had my base model solstice for awhile, and am now looking at that big step- adding a turbo. I already am lowered and have a dual exhaust so performance wise the car should be able to deal with the extra power. Also it’s an automatic so from what I’m hearing the trans should be ok, don’t have to worry about burning it out in a month(knock on wood). I’m looking at getting a turbo kit from eBay as that’s a grand cheaper than anywhere else I’ve seen, but before I actually buy the kit(linked below) is there anyone who has used this that had issues? Kinda feeling like the fact that an eBay turbo kit is ~$1k cheaper than anywhere else maybe should be a red flag, or maybe it’s just cheaper.
also, I pretty much am aiming for 300hp, that’s kinda the magic number I want to go for. Sounds like a stock gxp is touching 260 so I’m hoping with a tune 300 should be pretty realistic...anyone have input on that?
Thx,
Jeff

here’s the kit:2006–2009 FOR Pontiac Solstice 2.4 TurboCharger Turbo Kit | eBay

Uhhh.... No.

Here is a quote:
  • We are the parts supplier, not mechanic. We can try our best to help with generic questions, but it is best to consult a professional turbocharger installer with specific questions.
    [*]There are no installation instructions included. The install is simple and most customers install it themselves in a weekend. If you cannot figure it out or feel uncomfortable with the installation, please have a professional assist.
    [*]Most of these parts are direct bolt-ons. Some are not.
    • The piping needs to be fitted up. Because of the bends and couplers included, it should be simple.
    • The T3 turbo flange needs to be welded to an adapter pipe or directly to the stock manifold.
    • To run this on a street car, the turbocharger down pipe will need to be connected to your existing exhaust. Expect to fabricate an adapter pipe or have an exhaust shop connect them.

I mean... fitting the pipes is part of a turbo install anyway, and welding the turbo flange shouldn’t be impossible; my dad was a professional welder and can do it if my garage welding skills fail. And it having to buy an adapter pipe is the only thing extra I have to do I can also live with that.

Do you want it to run or not run after bolting it on... do you want someone to talk to that has sold hundreds of turbo kits for our specific platform or do you want the 'no instructions' guy... do you save the thousand dollars now and waste your time or pay the money for plug and play?

We have one member who went down a similar path. He is on his third or fourth motor. If you are asking opinions mine is buy a knownkit from Paw, DDM or Hahnthat will potentially save you years of headaches. Or just enjoy the car as is

If you set aside the installation..

What brand turbo is it?
What brand CAC core is it?
How thick are the charge pipes?
How many plies are the cuplings?
The clamps will need to be replaced with T-Bolt clamps.
No mounting brackets for the CAC.
No oil feed line.
No oil return line.
No coolant feed line.
No coolant return line.
No tune, and honestly don't know if you would find a reputable shop that would be willing to tune it because of liability.

RPM has a kit that you can buy that is almost 100% OE GM parts. They are the exact same parts used on the GXP and Redline. It includes the tune as well. The cost is 3,000.00 but it is a COMPLETE kit from start to finish with every single piece and part needed.

IDK what year your car is. If it is an 06 Solstice then the internals are forged and you should be able to get about 430 - 450 HP (flywheel) out of it using the RPM kit. If the car is a later MY then you will get about 300HP out of it. GM removed the forged internals sometime in 2007 I believe.

Your other option if you want to keep the price down is to look for some of the parts used. I have almost everything needed used and if you are interested send me a PM.
