spend £1K or 2K on an evo and you'll have a missile
1k might buy you a nice exhaust.
People think buying a turbo and tuning it is really cheap. If you want big power you pay big money.

Look at the prices for these kits which are all prices not including fitting.
Evo's arent that much fun unless you spend silly money to make them silly powerful, and they just have a horrible image and sound crap.
Recently finished a 600bhp evo7 engine and that cost him about 8k just for the engine, no idea how much more he spent on the chassis but he had all the top names for everything from wheels, suspension, exhausts, intercooler setups etc. Must of cost him about 20K total.
