> someone with no car tuning / mechanics skills

I'm just going to pull the band-aid off, you're probably not the target audience for a drag-race sleeper rig.

Money, lots of money.

Vermont Sports Car.

They build all the fast Subarus for everyone; Travis Prastana, Bucky Lasik, Ken Block, Lia Block.

The Huckster, the Project Midnight; all them too.

Honestly, just learn it like anything else. Understand the basic components of an internal combustion engine (block, crankshaft, rods, pistons, camshafts, cylinder heads, valves, intake and exhaust manifolds), the 4 cycles the engine goes through (intake, compression, power, and exhaust), how fuel delivery and ignition systems work. And then there are tons of resources on tuning and you can get the software for a laptop.

Premade as in have someone built it for you? Well, the same way they did it. You offer up a load of money to a reputable build shop and come back in about 2-5 years depending on how busy they are.

Unless you would be planning to keep it at a race track, you would not want to own a car like this. It would almost certainly be miserable to drive at legal speeds. That 2.0L engine isn't going to make any useful power below 5-6k RPM. Keeping a turbo like that spooled for any meaningful duration is guaranteed to get you pulled over by the police.

You don’t- without that knowledge you would not know what to pay someone to build and why. It’s also going to be extremely complex and unreliable, and likely not street drivable or street legal.

Nearly impossible. For the same price and effort, you can probably get a high end Porsche 911 or similar which will be way more practical.

The next level up would be to get a modified car from a company that has very strong ties to the manufacturer, such as Ruf with Porsche, Roush or Saleen with Ford Mustangs, etc.

Trust me either of those options will be more than anyone but the 1% top skilled or thrill seeking individuals can handle.

Something like that:

> Pickup trucks are great, but they're only available in "behemoth" size in the US.

Not all trucks are 1/4 or 1/2 ton in the USA.

There's things like the Honda Ridgeline, Hyundai Santa Cruze, and the Ford Maverick

Subaru had the Baja for a little white but they only sold a couple thousand per year.
