Forged connecting rods, forged pistons, and more fuel (pump & injectors) at a minimum. 400 seems excessive for most Goblin applications, but you do you.

I'm even less knowledgeable about the 4T45 than I am about the 2.2L, but a quicks search tells me that trans would be iffy around 400, and is better suited to the low 300whp range. Granted, that information came from a Grand Am forum, and it's likely to live longer in an easier life in the back of a Goblin. I know the RWD 4L60's lifespan was inversely proportionate to how much heat they saw, and I'd imagine the same would apply to a 4T45 with some power put to it.
I found a company selling tunes for the HHR SS which has the same 2.0T as the Cobalt SS/TC. Their Stage 1 tune on a manual trans takes the motor from 260/260 at the crank to 290/340 at the tire, whereas an auto goes from 220 hp at the crank to 280/300 at the tire, so take that for what it's worth.
The 2.2 probably needs rods and pistons to live at 400, and definitely needs a fuel pump and injectors to get there.
Keep in mind, too, if the Goblin you're looking at is built off of a 2005 or 2006 2.2L, then its computer can't be tuned, and you're looking at a lot more work to make any more than factory power.

If the builder is who I think it is, then I would endorse that purchase.
I wouldn't let a power goal stand in the way of a Goblin purchase. I drove my build around for a little while with the supercharger bypassed, probably making less power than a stock LAP (2010 2.2L engine), and it was an eye-watering experience. A stock 2.2L and auto trans will probably launch incredibly hard and incredibly consistently, as I'm sure anybody who's driven such a build would attest. I think if you drove it for a little while, you'd find it so fun that it's hard to take off the road for upgrades, at least until/if weather forces you off the road for a season (maybe not a thing in Florida, though?)

Bolt on a LSJ supercharger for $2k which is good for 250 whp and call it a day.

I just swapped out my LSJ supercharger for a ZZP Z54 Turbo. I'll sell it it you if you end up going that way
