Sure you can run that same amount of boost. You put "X" PSI spring in the wastegate then you can control more boost from there with a boost controller. FWIW most just do a 10 PSI spring and then when they are ready, increase boost from there. You can easily run a turbo kit without the intercooler if you want. It's just going to limit you on how much boost you push, but sounds like you just want to get in the game and work from there. That's a good starting point.
You are going to want at minimum 42lb injectors which will limit you roughly to 400ish flywheel horsepower. With that it would be a good idea to at minimum put a better fuel pump in there such as a racetronix.
