Yeah. Easily. Especially if you don't turn your own wrenches.
Even small things add up. Like decent rims and decent tires is just under 4k. Example bbs chrs + michilen pss + mount/balance + alignment + shipping and tax etc.
Let alone a suspension that can really handle 700whp correctly. All the upgraded arms, bushings, quality coilovers not the 1400 stuff, a quality differential, corner balanced and set up by a shop that knows what they are doing, the list goes on.
With wheels and tires I’m into my car a little over $16k above what I paid for the car itself. My setup would be right in your power goal. I just started a forged short block build and built trans. Add in the trans and engine build and you’re pushing $25k. At that power level you’ll eventually need transmission work of some kind and forged rods/pistons down the road.
