Quoting 91GSR:
actually having a larger housing can be less beneficial than you think. with more space in there but the same size wheel there is more space for the exhuast gases to just pass by instead of actually pushing the wheel. im not saying it wont benefit at all becuase with a larger volume housing stands to reason more air...and more air = mo powah lol. but like i said...more space without a wheel to fill it just gives space for the air to pass thru instead of pushing the wheel
er, 16G turbo's have the same exhaust wheel as 14b's...
