I am interested in getting a silvia s15 (im in Japan), but i have been a honda guy most of my life so im not sure what would be some of the first parts i would buy to get some good power. I was thinking Intake, downpipe and exhaust, and maybe a boost controller. Im new to nissan so i want to know what im getting into before i buy one so any info i need to know would be appreciated. Thanks for looking.
