Not that it's so bad, but expensive, and if your system hickups, you can have some major internal malfunctions...
Besides that exactly, how much power are trying or planning to make? This isn't really a simple beginners project, this is pretty involved. From the sounds Of what you have done so far, some pretty simple bolt ons (or offs as the case may be), this should be followed up by some other mods to tie it all together. Like was mentioned above, tuning to get all the parts to play well together, gauges so you actually know what's going on inside the motor and so on.
A bunch of bolt on performance parts from some go fast magazines thrown together without coordination will get you nothing but low reliability and a thinner wallet... This isn't a rubber stamped 302 that you can find a dozen of sitting in the corner of the bone yard waiting to be rebuilt, it's a $10,000 highly (if not overly) engineered machine.
Yeah it's possible, but again, what are you trying to get out of it?
