I have a 97 Civic HX. I currently have a cold air intake, headers, full 2.5 magnaflow exaust.

What my current project is installing a 98 Port and polished civic EX head onto this car. After installing this how much Hp do u think my car have.

a stock 97 civic hx has 115hp, but the head should turn the car into a EX basically is what my mechanic said.
thank you for your time.

 

not much and wrong area

 

Where do they come from?

You should see a net of about 10hp or so. Perhaps 5 of that will find its way to your wheels.

 

Like Superhatch said, I think that will get you around 10ish extra hp. I think that you will see a pretty noticeable difference at higher engine speeds too.

 

Put the **** on and dyno it..

 

wrong forum and too many factors

 

I'll reply with the classic...

No way to know for sure. A lot of other factors are involved.
