Figure what, about $4k to build the engine and at least that much in a turbo kit? Then $3-4k+ into the suspension and brakes. You'll need to spend another $3-4k on wheels and tires that will hold the power.
Figure that the 2000 BMW M4 has just under 400hp and is faster in a straight line than a rocket powered car. I'll find the clip and post it if you want, but it's a long load unless you have high speed. This car also weighs in at a hefty 4000lbs (1825kg). My point being, you really don't need that much power in a Honda that weighs around 2000lbs. And to top it off, you can buy a 2000 M5 for around $25,000. Your 600hp will cost you almost half of that.
