You could add an Electric Water pump to the mix, 8-10Hp.
Have you done the cold air mod routeing the air from the front bumper to the stock airbox.
Use some Mobil 1 0-20 oil good for 3-5 Hp.
Use Oil Extreme good for 6-8 Hp.
2.5"-3" catback exhaust using Magnaflow straight through muffler, remove resonator.
