If money isn't a problem, my car would be a rear-engine and RWD Camry, running a body that has been designed with air tunnels, and car completely constructed out of carbon fiber and plasma-welded connections. Oh wait, that type of bodywork sounds like what a jet fighter plane utilizes
Questions like this is not realistic, so I don't think about it much.
I think somehow my Camry build-up is making everyone think that I am all bling

My Camry does take money to build, but it's an amount that almost everyone of you can afford. I only work with what I have available, and my Camry is what I have ended up with based on my current know-how and budget

It's a good amount of money, but money I rather spend on my current car instead of purchasing a newer car like most people. So far, I have spent about $14000-$15000 CAD on my Camry, but this money couldn't even buy me a new Corolla or something remotely decent. So instead of buying a newer car to replace my 10-year-old Camry, I went all-out with my Camry

Knowledge is power, and once you get connections with parts suppliers, fabrication shops, as well as being mechanically inclined, etc... there is really no stopping you. I have came a long way before I built my Camry, so it's not really a first-timer type of work to be building a car and an engine that has no aftermarket support whatsoever.
If you think about it, I had to be familiar with the following things before I even decided to tackled my Camry project:
- understanding of the motor -- something like an ASE test would be sufficient
- turbo systems and turbo tech (specs -- A/R, trim, workings, etc..)
- machine work -- measuring for custom valves, pistons, etc..
- Mechanical skills -- engine overhaul, etc...
- Plumbing -- fittings, fluid connections
- Fuel System -- custom fuel system, etc...
- Electrical -- management systems, wiring, sensors, understanding them
- Tuning -- no one can tune your car 24/7 Do it yourself or go home
- Welding -- pipes, custom brackets, etc...
- CNC Machining (shop connections)
- hookups with shops for wholesale prices and deals
- etc...
Oh, to answer the question, I would rather have a supercharger than a turbo. Although S/C's are very inefficient, you can always make more power to compensate for the loss. If I were to race a turbocharged car with the same HP/TQ as my S/C car, the supercharged car would have more chance to win. Although it will take A LOT more money and effort to make the S/C create the same amount of power as a turbocharger, but powerband vs powerband, the S/C will get the upper-hand.
My opinion to why S/C is better:
S/C
-- only positive displacement-- no centrifugal "turbo on a stick" crap:
- no lag -- instant power
- if intercooled, potential is unlimited just like turbos
- less engine recovery time -- air and boost into the engine is very consistent. Less chance for misfires or bogging. Less strain on the ignition and fueling system.
- better traction -- if rubber and suspension can hold the power, the S/C will always have better traction due to smoother power delivery
Turbos (negative points):
- lag -- no matter how small the turbo is, exhaust gas is the byproduct of combustion and engine RPM. Engine RPM is constantly there but exhaust gas is based on engine load.
- exhaust gas back pressure against the motor. In order for a turbo to work, there must be pressure between the engine and the turbo. This pressure also diverts exhaust gases back into the combustion chamber. S/C's on the other hand can still use free flowing exhausts and headers to maximize combustion efficiency.
- power transition is bad for traction and driveline components. When reaching higher power levels, a turbocharged car will begin to have a narrower powerband. Thus, the "on/off" power transition on most high powered turbo race cars.
