Hey guys, I recently bought a 2003 sportivo and i'm new on the toyota scene, first thing i wanted to clarify was that it had a 2ZZ engine? I've saved up a small amount of money ($4000) and i want to spend it wisely, I was thinking the following; -Injen CAI - I did a little research, it seems most of the cai designs are similar, are there any cai that IS outstanding over the others? -CES catback -I'm going with this option only because it seems to be the popular choice, any reasons why i should go another route? -Headers - Here's where i need your help, which header is the best bang for buck? Also which headers gives out the most gains? -Chip - Is there some sort of tune or unit that's popular? Details on this would be great! I'm not looking to do any internal mods, so the rest of the money will be spend on a set of coilovers and braces. I'm aiming to hit the 125-130kw mark, Is this realistic? Any help and pricing would be appreciated, look forward to hearing your wise responses! thanks guys
