The G-Power supercharger kit can be had for $2,100 from Schmiedmann (link here). That does NOT include an intercooler, an oil cooler, or installation (assuming you're not doing it yourself).
once the project goes live, i'll check whether it is better to go 3'' or the next smaller size.
one thing though i'm not sure of, would keeping my twin-piped rear stock muffler cause any restrictions or is it better to change it to a single piped muffler?

You can honestly build yourself a turbo kit for about $2500 with ALL parts and labor NOT including the tune. The tune would probably cost about $500-1000 all in all. Not to bad but is it worth it?. That's what you have to ask yourself. And this is keeping the same compression on your engine so you'd only be able to do like 6psi safely with it unless you dropped the compression a bit.

the manifold you can buy for $140, the piping for $100-$200 the rest is up to you.
