i have a 2002 honda civic ex VTEC with 127 HP stcok.
I am about to add ...
-GReddy Cat-back Exhaust
-Intake
-DC 4-1 Header
-Bosch PLatinum Spark PLugs
-High Flow Cat

After doing all these mods, how much HP do you think i can expect to have?
I figured around 160, does this sound right? Anyone?

 

i have a b-16a swap in my 1988 crx with intake,exhaust and put down 126whp.So i think 160 is way to much to ask out of a car with 127 stock.

 

im talkin at the crank, not at the wheels

 

oh yeah i also forgot to add im getting an underdrive pulley
so thats catback, header, intake, spark plugs, high flow cat, and underdrive pulley.

 

How can you have a B16A with 126 hp? You must be running on 3 cylinders or something.


Oh, and I think you can expect between 150 and 155, 02CivicEX.

 

but yeah, somethings wrong with the b, it should be closer to 135-150 at the wheels.

 

Id guess just over 140 to the crank... 150 if your lucky. Your biggest gain will come with the header.

 

ahh damn, i almost corrected you till i realized you werent talking about the b16 anymore. yeah, about 135-140 crank HP.

 

yeah but my 126whp smashes like hell but i have no clue why im only putting down 126 when it should be 135-150?i just did the fuel becaues it was lean.now back to the dyno.
