I'm not living paycheck to paycheck actually spent 5 k over the winter on it. But if money is not an issue with you guys then why not go out and buy a new gtr instead of driving a 20 year old car? The original question was are the massives that much more worth it in terms of proven performance over the bells? If I only gain a few horses then ya the rest of the money I save can be better spent elsewhere. Shit the 300 dollar godspeeds with ducts have been proven to perform as good if not better than other options that are 3 times as much!
