3.0s aren't quite as simple or reliable, but with a proper exhaust setup, they ARE far more powerful than the 22R series engines. The OEM manifolds are junk. Optimally, you would have um... 2.0 inch exhaust x2(each side separate), but that's a lot of money. 2.5 inch is fine if they are going to the same muffler.
BUT... expect such a mod to run $600+ in parts.
