how to make more power and better sound for my 5sp 1992 civic dx with d15b engine

 

Sell it and buy a fast car.

 

Turbo

 

what about full catback system

 

No

 

No. x2


Either turbo it, or sell it and buy a fast car.

 

If you want your car to go faster, spend about 2 weeks READING.

 

Seriously, check the stickies. There's only a MASSIVE GUIDE in there about how to make a civic fast.

Let me condense it for you: $5000 for boost (it could cost you less than half of that, but I'd bet you want instant gratification, not parts hunting) or $10k+ for a built to hell motor.

 

Put a Fender vents on and plenty of performance company stickers. If that doesnt work(definitely will) than do the "ferrari 458 mod" or if on a budget "5.0 coyote mod", can be found on google or dupont registry.

Hope that helps
