Turboing should in no way even be considered to be rice, or should the two be in the same sentence unless the words, "sounds like you have a" precede the word turbo.
With the mustang community turbo cars are relatively new and quite rare, especially for cars running the 4.6. A turbo will provide more horsepower than a comparable supercharger and has more power under the curve. Both equate to better times and a more fun and enjoyable car.
With us (mustangs), there are relatively few people who have much knowledge of turbos so much of the tuning and getting things to work just right requires some trial and error (hence the reason why my car is down so often). The install isn't much more than just a bolt-on, follow the directions, type of thing, but there is just so many more components that go with the turbo than a supercharger it makes the turbo kit a much more lengthy and sometimes complicated install, there is also the problem with space constraints. I did my install in the garage and have had no real problems with the work i had done. I wouldn't consider myself a master mechanic either (the mustang is really the first car that i've really worked on). The tuning is extremely important when pushing the limits of the block, which is where most turbo kits will put you. The mail order tunes are not ideal, but it is damn hard to find someone to do a good dyno tune locally. Also, the car usually requires a custom burned chip. Any aftermarket tuneable ecu(the most ideal tuning method) is not cheap and will usually kill all chances at passing emissions as testing is now done by plugging into the diagnostic port and pulling codes.
Does that mean that my car is rice or that i am a ricer because i bought an off-the-shelf turbo kit and haven't had the time to get a decent tune yet? or that i have yet built up the bottom end? or that i went turbo instead of doing a 5.4 DOHC navi swap?
If you think that a custom kit is the only way to go i would suggest going to the junkyard section of the turbomustangs.com forums and look at what they are doing. They are making the kit themselves and usually dialing in all the timing and fuel issues on there own, and are making amazing amounts of power for amazingly little amounts of money.
Just because something is becoming popular does not mean it is rice. It is when it serves no real purpose, that it becomes rice. A turbo is a great way to make tons of power.
