I really hope im not thread jacking here, but i plan on installing the fswerks kit later this year. anyone have any knowledge on how far you can go with a stock d20 and auto trans? I was thinking about upgrading to the GT28RS instead of the GT28R. And to answer the OP's question, if you want reliable boost you gotta lay down the cash. Period. Quality never comes cheap. Fswerks might be expensive, but that's because they're reliable.
