For 6 grand this is what I would do. Get a complete ls motor swap, and get it swapped in. That should be like 3000. Then get a nice complete aftermarket turbo kit like revhard or something like that, and custom 3in exhaust. Limit ther boost to 8psi and have a reliable car that makes at least 230 whp. If you want more power in the future you always have the option of getting a nice set of pistons and rods, sleeve the engine, upgrading the fuel system,upping the boost etc etc..
However, youve got a TON to learn so before you spend a penny do a lot of research on forums like this one and Honda-tech. Good luck
