I have a 99 civic si with 49k miles on it, mint, and im deciding between selling it or boosting it. My question is that I want like a gain of 100whp and what setup i can run or which turbo to go with without having to spend a ton of money. I dont want it to be anything obnoxious, i just want some nice power out of a mainly stock looking car. Mods now are header intake catback, skunk2 proseries coilovers, shortshifter, cf hood. Thanks

 

what is your budget? a 100whp is easy to achieve. b16a puts out 135whp on a dynojet, so 235whp is about what your looking for? Greddy kit is whats gonna fill that desire best imo. There not the best kits for everyone but there good and reasonably priced for those people looking for under 300whp just add a decent intercooler and piping and you should be good to go!
