well if i am not mistakern the stock size for inatke and exhaust for the hf is 1.5 inch so i may need to get some custome pipes. What engine is a better bang for my buck. i want a B16A1 but i don't have that kind of money. It would be better to get the VTEC right!? (I know VTEC is the shizzlebut..) would it be a pain to put in an HF?
