Not to poo on the subi guy's parade, but it makes ZERO sense to me to spend $10k on an engine, $10 a gallon on race fuel to make 300hp, and then have to deal with turbo lag.
$1000 on a stock NA J35, pump gas, 300HP and GO!
While I mostly stick to this, I do buy all the cheap 22LR rifles I can. I'll then clean them up, function test them, and sell them on the cheap to my buddies with young kids.
