You can customize a turbo....buy a turbo for $500 somewhere lol i got my T4/T3 for $300 from a friend, find some place to put it and custom make the pipes, find a program to change fuel curves, find another program to change timing because otherwise i think you will only be able to push 3 to 5 pounds without blowing up your motor and uhh...injectors, intercooler, and your set. My whole setup is only costing me $1,244 cause that STSturbo.com crap is good but not worth $3,000 and then plus all the stuff you need to put on top of that...
or just go get a supercharger
good luck
