Hey Guys I have a 05 zx3 se duratech 2.0 and just wondering what mods would be best for more hp, I already have a fs cai exhaust hr lowering springs and 18.75 exel wheels in hankook tires, and looking for tips for mods that will increase hp?
first mod is usually CAI, which you have. from there most go for exhaust, cat back if you to be legal and flex back if you dont care. if you have a manual tranny (MTX) then i would suggest an STS (short throw shifter) no HP but it will make you faster. If you have an auto (ATX) then go for excall 2 tune for upgraded fule and spark tables along with adjusted shift points. If your really serious, then go for cams (crane 1 are nice for street, and I think theres a group buy still going on on FJ) and also a cam adjustment tool and headers. That should be enough to keep you and your wallet buisy for a while
