This is exactly why I went with audio and a good paintjob rather than trying to make my car what it won't ever be anyway ~ quick. I have a twincam engine and it still isn't moddable. It was built to be an economy car and that's all it will ever be. Your CX Civic is the same way.Those cars just aren't fast- the head doesn't breathe, they don't even have VTEC (have to get an EX for that) a turbo would be a waste on that motor. Let me put it another way, that motor turbo'd likely still get smoked by my stock Si (k20)- they just aren't quick at all- so just enjoy the 35-40mpg you will get and roll that cash into some bichin' audio gear. Besides, if you put a header and fart pipe on it you will join the ranks of people I laugh at when they romp on it at a green light, and it makes a shit-load of noise with no acceleration to match. Single cam Honda motors are never worth the jack people put into them, because a stock twin cam Prelude motor will bich slap them every time. By the way I work on Hondas for a living.
'90 Accord Coupe w/ H23A around my town running 12.1-12.3 //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif. But as suggested above in other posts, I'd get a GSR swap or if you really wanted to get a nice motor...K20A.Ok, bolt ons only help out a decent amount if you give them a decent motor to work with. If your dad wont let you do a motorswap( I would recommend an H22A prelude motor myself) or a turbo then you are screwed. You can buy an intake, headers and exhaust and the only noticeable difference is the sound. Maybe a little power. If you can get a turbo then I wouldn't recommend running more than 7-9 pounds of boost on stock internals. Then I would invest in a Hondata ECU and get the **** thing tuned professionally. The whole setup with proper tuning is about 4-5k. Turbo's give you on average 7-8 hp for every pound of boost. Sooooo....thats between 60-80 hp gain. Now, for the same price you could go with the swap which will give you maybe a lil more power and the ability to add a turbo and other mods for a hell of a lot more power than you will get out of your current motor. Just remember, bolt on's are only as good as the motor you put them on. Hope this helps.
