Just got it a week ago and, well, it needs more power. So far I've read that a good turbo back exhaust, up-pipe and the Access Port is a good combo and is good for 50whp give or take. What about intakes, or just a K&N, are those worth doing? Also what about a bigger intercooler in the stock location? Will that help performance any or be useless unless you get a bigger turbo and crank the boost up? Lastly, what kind of springs are available for the wagon? Don't want to drop it much, maybe just an inch and preferable not much stiffer spring rates than stock. Thanks in advance,
