Maybe less if you have a good quote/shop.
Yikes. That's a lot of cash.

He bought a brand new kit direct from Cartuning, he wasn't the one who bought my used kit

Yes, my kit was bought new. You don't have to do all I did to my car, you can bolt on this kit and pretty much go. I had done 1.8 rocker arms prior and also added Patriot Gold Valve Springs. I had my intake manifold ported as well before the turbo went in. My quickest times without the turbo and running slicks was 13.0.

The transmission upgrades were necessary for me as I wanted to run the car on slicks. It is no where near $10 to 13k to do this. The Turbo kit is $5k. You will not find a turbo kit for any other vehicle for around $5k that includes everything Kevin puts in the Car Tuning kit. Let alone running mid 11's and picking up a ton of horsepower!

My transmission rebuild was around $1450. Now I did add some "unbreakable" parts to my transmission due to my intentions with the car which will add to the cost. This was due to running slicks and trips to the track. That included a GM 1" Racing Chain $1k, hardened input shaft $350, PI 3000 RPM torque converter $575.

Take some weight off your rear tires and if the track can hold your tires this time put some spring blockers in the rear

What size is the downpipe on the kit? I thought I read it's 2.5". If so do they offer an upgraded kit to 3"? Do they have any other turbo options? What is the A/R on the turbo with the kit?

So the rebuild/strengthening was ~$3k?

Yep, around $3k in the tranny. The GM 1" chain is no longer available, so good luck finding one! The chain is made to handle up to 1000hp, I don't believe anyone has ever broken one. You can go with a 7/8" chain for around $400 or so, but still could be weak at some point.
