No harm in trying, worse they can say is no, which they most likely will unfortunately. GM is under no responsibility to make aftermarket/team up with a company to make an aftermarket part for their production vehicles. and chances are that if they did, it would be ridiculously over-priced like every other GM accessory they sell -___- wishful thinking though lol

GM wont do it. You can ask all you want but it wont happen.
Having pulled apart a 1.8 head, and making some assumptions on the remainder of the engine based on past GM engines, the 1.8 might hold a few PSI before it lets loose. A full build will most likely be needed to handle much more than that from a properly sized turbo.

Yes.
Also, we might get, what, maybe 50 people that would want a turbo in their 1.8, 34 that would sign a petition and maybe 5 that would actually outlay the cash for it.
The problem is, such tiny, small demand numbers will never, ever justify the financial expenditures that GM, or any manufacturer, would incur to do something like this.
To make something like this feasible, it would either cost an absurd amount of money - in the extreme realm - or would have to be produced at a mass production level.
Just because you ask something, doesn't mean anyone's obligated to give it.

You need to skip the GM step and just go to an aftermarket supplier with a deposit and a group of people actually willing to put money down to secure prototyping. That's the only way it will happen. An enthusiast shop would build a kit for anything but the cost is just flat out more than most in this market segment will ever spend on the car.
350Z guys spend 5-6K for a single turbo kit for a 50% bump in power. Would you be happy spending $5K for a 180whp sonic? It would make more sense to trade it in for a 1.4L, and then with a tune make that same power without exploding the bottom end of the engine.

An enthusiast is also willing to risk blowing his engine by running it close to the max it can handle. GM isn't going to put their logo on something that lets you run up past the red line their engineers have drawn.
Why, other than just wanting to do it, would you go with rebuilding a 1.8 from scratch, when for the same effort and considerably less cash you could swap the whole engine for something more powerful and designed to be more powerful? As already mentioned, the 1.4T would be an easy swap, but you could also try swapping in a 2.0T...

This, IMO.
And I get the "But I wanna build it, not just be another 1.4L". I totally understand that....then join the people that are putting aftermarket turbos on them. Take advantage of the leeway that gives you over the 1.8 in bottom end strength.
Or a 2.0 swap gas or diesel
Or don't, the world would be boring if we all did the same things with our cars. Just my .02

Well all fair points but its just me wanting to be different you know one of a kind hence why i have sonic on my car and i got the sedan and why i got the 1.8 i appreciate all your guys inputs but i guess ill just build up what i can for now when the engine goes ill do a full swap but till then I'll keep dreaming and waiting for a kit even just like 5 to 8 psi I'd be ecstatic about

Here's an idea,
Buy a 1.4T, no petition needed.
If you want more power, go for a GM 2.0T, it's already made, produces 275HP stock and is flat out a better engine in it's stock form than a 1.8.
Owning a Sonic with a 2.0T in it would certainly make you different. Just figure out how to fit it, and it's supplied transmission in the car.

Figuring how how to fit w/o breaking the bank! Both the 2,0 engine and its transmission (F40 if memory serves) are bigger in length and engine in width than what is in the Sonic. But I would like someone to do it (makes no difference which engine) and if it works I may follow. I have enough firsts for Sonic mods so I am perfectly willing to let someone precede me.
