Unless you're pushing some serious horsepower it isn't needed. For a stock motor retaining the stock pan it is unnecessary. Your engine's bearing clearances do not require the use of a high volume pump. Your motor does not stay up at high RPMs for extended periods of time and/or distance (think NASCAR). Whenever your oil starts to run low before tripping the low oil light you are sucking the pan dry. High volume oils pumps require more effort to turn compared to a stock oil pump. If you're going to run an oil cooler, higher capacity oil pain, or a turbo/supercharger requiring an oil feed line then a high volume oil pump would be a necessity. Other wise, if you're not doing any of the before mentioned stay with a stocker.
