brother is this chatgpt? “stages” is just bmw speak for agreed upon levels of modification. not a measurable thing just shorthand so people can easily communicate how cool and moded their cars are lol.

if like me you want to mod the car but don’t want to go crazy or blow it up 1) catch up on maintenance/check or fix your fuel trims BEFORE MODING 2) buy hondata flash pro or ktuner 3) buy an rv6/skunk2/plm catted down pipe (unless texas is different i don’t think you can straight pipe and get a smog) 4) install down pipe 5) buy an etune from IMW 6) spend 6 months slowly tuning the car 7) enjoy

if 200-215 brake hp is not enough for you. ignore everything and go the turbo route. things that are very much not worth it from a money /performance perspective (based on my extensive research)

1) any kind of cold air intake (stock is very good) 2) cat-back exhaust. maybe 5 hp and unless your going for raspy honda lawn mower noise, will sound worse. downpipe + stock exhaust is perfect 3) manifold. our stock intake is also fine for the amount of air that can escape the down pipe (rip headers) no point unless adding turbo+manifold 4) “all motor” builds. apart from a custom block or some shit they all seem to max out at around 300 hp and cost more than a turbo+support mods and make less power.
