well I disagree, sure if you pay a mechanic it's going to sting you bad regardless but if you do things yourself then it shouldn't. Twice in the last few months I have seen RWD converted 20V engines with full aftermarket ecu's and looms with a tune for sale as a package for $2000, I think one even had trumpets. All you would need is some intake socks, install the wiring loom and get the exhaust made. Thats it! Play your cars right and it can be really cheap. If you pay a mechanic to do all your work then I suggest a different model car altogether unless your really into it.
