Sorry to say but $10k isn't going to get you very far.
You need to remember its one thing to build a long engine, but to build a strong engine, ie 'race' strength, factoring in turbo setup, fueling, cooling, clutch, brakes, engine management, tuning, tyres to get the power down etc - Well, you get the drift.
Also, why does track car automatically mean going for a 'top mount' turbo?
