I have a rebuilt wrx, 06, tr. Cxr500, 10.5cm, turbo. Im pushing 16psi ish 330whp. Now I think thats fast enough for me but I would not mind being faster for a cheap buck. I have a little over 300 bones to spend. Now its between 3 things UV coat on my oxidized hood, Perrin shorty maf intake + tune or better speakers. Now my hood looks like crap thanks to cheapo gel coats from seibon and socal sun, so a new coat would put out that eye sore. Im maxing out my intake likes its cool I need a map stat so I can go faster and my turbo just gasps for more air so a 73mm or shorty from perrin along with a tune plus corn, Ill put me at 400 whp but will stay at 350ish tq considering my clutch will get tourched lol. If you have a wrx tr you know what I mean about in need of better sound quality. I am at a womping 80 watts factory stereo output so It would be nice to expeirence a little bass in my life lol. What do you guys think. The mod bug is biting me and I dont what to spend my bday money on.
