what turbocharger / intercooler should I get?

I own a late 80s dodge 2.5l four cylnder car (would rather keep the make and model to my self) stock it makes 150hp and 180lb-ft of torqu it hase a SOHC and 8:1 compression ratio and has a boost control system that only lets it have 4psi untill you get to 4000rpm then it boosts to 10psi (that is fun) stock it has a crappy mitsu turbo on it but im looking to upgrade (add a better turbo and an intercooler and blow off valve) im not sure what turbo or intercooler to get as most turbos are way to small and i have plenty of room for the intercoler actually im not sure if any one makes and intercooler that wont fit behind that grill (the intercooler piping needs to be 2.25in and I want the turbo to have a 3" down pipe and exaust system) im looking about 300hp
