thank youYou have various options depending on how much power you want to add- turbo, supercharger, build up existing engine or replace with another engine. Figure this out first and then do some research on the available options. I would recommend talking to a tuner/shop in person so they can help you detrmine what is appropriate and possible with your car. I visited several shops when I did my Mustang and found this to be the most sensible way to determine which route to take as well as to determine what the costs would be.
CT engineering makes a supercharger! +50hp completely bolt-on. KTUNER V2 or HONDATA may be needed.I was thinking about engine swapping my TSX for more power and maybe a turbo I keep getting smoked by my friends = ( any ideas? and I'm thinking about dropping like 5-6k
