I hate to be that guy, but it "Depends". I'll offer this, though:
What do you want for a finished project? Do you want it ASAP or are you going to slave over it for several years and build a show car? How much are you going to spend on the engine, transaxle, paint, interior, carbon fiber goodies, and anything else? How much will you do yourself vs how much will you farm out?
The SL-C Configurator on RCR's site is a barebones starting point. Go over the parts you've selected multiple times. You can decline parts that you don't think you'll use or you plan on buying third party, like seats, taillights, dash...whatever. RCR will knock that off the price at time of order.
My car was just under $60k, I declined some parts but also chose some carbon fiber parts along with the RCR billet shifter. I took all the interior finishing parts, but now that I have them I don't think I'll use all of them and probably would have declined some of them.
Shipping - again, depends. I used Stewart Transport. They were fine to work with. I'm only 3 states east of RCR, shipping was $1700. If your're further away, it's obviously going to be more.
Engine and trans? What kind of engine? Going to have RCR get it together for you, buy third party, or DIY your own engine and find a used trans? Minimum for a decent dressed LS3 crate engine is probably $10-13k, you could take your chances for a dressed scrapyard drop-out, or a new barebones crate LS3 longblock, for $6-7k. Jack up the price to $15-20k+ if you start slapping specialty parts on it like turbos, forged parts, flat plane cranks, whatever. Add more $ for engine accessories like alternator and all the rest, ECU, etc. DIY isn't cheap, either, because we all tend to go a little crazy with forged parts, flat plane cranks and whatever else you can imagine plus you're paying retail for all of it.
Transaxle. RCR was selling their Graziano for ~$15k. HCF had a couple for around $20k. You can also use a Porsche transaxle, I don't know how much those are. I bought a used Graziano for $7k but it needed work, sent it to HCF to have it gone through, drop gears and overdrive done, and by the time that was all done it was almost RCR's price, but there was some savings to be had doing it that way. It took months of scouring the web, learning Graziano transaxle codes, and sifting through all kinds of damaged transaxles to find one in decent shape for refurbishing.
So my price for car, engine, and trans were just over $70k. That does not include wiring, dash, paint, A/C, engine accessories, or basically anything else to make this car drivable and run.
Then there's the rest...
Paint or RCR gelcoat? Sky's the limit for paint. Show quality paint will probably be $20k to start. RCR gelcoat prices are in the configurator.
Interior? Huge price variables. RCR interior parts are in the configurator. They're good, but pretty minimal. If you want a supercar look you need to fork out a lot cash and elbow grease if you want to have a more refined interior. Top tier seats in carbon probably start in the $5k range. Each.
Personally it took me a year and a half of reading these forums, everyone's build logs here and elsewhere, pricing parts and accessories, and various custom car building videos, before I commited. I bought the engine and transaxle first to spread the costs out a little, I waited for the best deal I could.
Building one of these cars is full of hundreds of very personal choices and decsisons. You could hurry the car onto the road with a lot of low budget choices and probably get there under $85k. Won't be pretty at all. Want a decently outfitted car? Closer to $100k. Serious show car? keep adding $$$ until you get there. Even if someone here had a spreadsheet you'd still end up having to add and remove a ton of selections because they aren't your preferences. You're far better off reading the forums and making your own decisions and spreadsheet based on that.
