im new here, i wrecked my 03 legacy december 2018 and decided id go into a little debt so i bought an 07 redline in a manual, with a dark ming blue paint job. this has been my dream car since i was 11 and i figured its worth it. its a little on the pricey side for a 19 year old but hey, i do my own work so that makes it bearable. the one ive got is a little rough around the edges but had been a great car for me. its hard to daily it but its what i have and im happy with it. its got about 130k on it and ive done a few mods to it that im happy with. after i sort out the issues im having right now id like to look into meth/water injection. not for huge horsepower gains though, im mainly looking for a setup that will cool down my iat and keep carbon from building up on my intake valves. let me know if yall have any suggestions.
