Just got a dose of reality yesterday...along the same lines of what people are saying.. So spoke with Rob from Z Car Garage in San Jose, CA. He's done some work on previous cars I've had. As a baseline with spoke about a few builds he's working on. One being a car in the 550 HP and the other 600 plus.
He stated the guy doing the 500 or so car is dropping 30k on the engine alone. That's just engine... This was a high level conversation and he didn't have time to do a deep dive into the nuts and blots of the build... But it did not include any body/suspension/tires or wheels or anything else... Just an FYI..
