I've been into cars for years, I've done the domestic thing and wanted to give this a try for a while. I've been looking for '99, '00 Civic Si's. Its something about the styling and that color blue. But anyways, after purchasing it I plan on mods, I'm looking to get around 400-450 chp. One is that possible to do on regular pump gas? And be emissions legal? I already know the bottom end will need to be forged, lower cr pistons, From Here I'm not sure what else I need for the internals? From there the usual bolt-ons and such. Turbo kit I was looking at dragkits.com To4b Super S trim, is this kit ok or can you guys suggest another one. I chose this kit mostly due to the price. What else will I need with that kit? I notice it doesnt mention new injectors, what size would I need to get? Also a FMU I didnt see that there either. Now my question is will I need to get it tuned after I install everything? Or is the kit like a bolt on kit. I know I'll see more hp with tuning but is it really neccesary. Will I have to get Hondata or something equivilant just to get it to run? If thats the case what will I need from there? Sorry for all the questions I searched as much as I could before posting but these were a few concerns I couldn't find answers for.
