[IMG]i/expressions/face-icon-small-puke.gif[/IMG] I just bought a 2002 Civic Ex and i have been doing some research on how much power you can get out of some of these performance parts. I recently read in a Honda tuning magazine that dc sports header, exaust, and intake only gives 7th generation civics 5 hp. Can someone that has has these upgrades tell me if it is really worth spending 1500 or so to do these upgrades?

reLaXedinca

DAMMMMM 5 Hp ummm i think whatever your reading is a misprint cause what i have read TCS from dc sports gives 9 hp and that only the exhaust or exhaust and headers im not sure but 5 horses is real bad for intake headers and exhaust i dont think that can be possible even with a k&n drop in filter uyou probabky get more power

Im thinkin I heard something in the 25 H.P. range for I/H/E . I could be wrong though, guys help me out if I am.

Edit: If you want to know more please search the forums first, there is lots there about this stuff.

an increase in 5 hp is pretty accurate. our civics aren't exactly mod friendly. if u slap an intake on a supra, u get like an extra 20-30 hp whereas for us, it's almost insignificant. the only major way to get hp for our cars is to go with nitrous or forced induction.

Look at the latest edition of Honda Tuning mag, it says that the I/H/E combo only gives off 9-12 hp @ the wheels.

AND THAT IS WRITTEN IN THEMAGAZINE

The 5 horsies was only for the headers and the exhaust I think. They dyno'de it. I know that the intake itself will give you about 5 horsies. $1500! Damn, I didn't know it was that much for all that. Anyway, spend that money to get your head shaved. Hehe. The cylinder head that is. Increase compression and get a copper head gasket. That will give you a much better horsepower increase than I/H/E. You'll probably still need I/H/E to get the most performance out of the new setup, but just the increased compression will put you at anywhere betwean 160 - 190 horsies. Anyway, that's what I'm planning on doing.

How much to you take off the head? Is this on the standard of VTEC? Would you then need headers and pipes to get that HP number?

Remember .. 9/12 HP at the rear wheels is like 15/20 HP at the motor.

It is expensive. I'm just waiting for the Jackson Racing Super Charger. Maybe even the Vortex Turbo. Either way, reliable power and the touch of your foot.

hey GREY.... are you seiorus that shaving my cylinder heads alone on my EX will get me from 127HP to 160-190????? WTF!! i had no idea that that was the case. if it is, screw the I/H/E plan! I'm going all the way with shaving!!!

LOWBOY

Its called decking the cylinder heads. And 190 is prolly pushing it. Port, polish and decking them would put you around 172 to the rear wheels. A company here in denver already did it to a 2k1.

FiresVTEC

there has been a lot of talk about deck/port/polish on these threads lately. it seems to be the best way to go for the money and the longevity of the engine...because thins like nitrous, forced induction and super/turbo charging can have damaging affects in the long run. Grey, when you end doing that let us know the details. thanx

I think when you do the shaving of that it intales more then just shaving the head. I think to get to that number of 160-190 w/out I/H/E you would have to do some major work. Such as Port & Polish the head, deck the block, custom high-flow intake manifold, high volume fuel rail, fuel pressure regualtor, 3 angle valve job, titanium rods and springs, blue print and balence of the engine, maybe knifedging the crank, lighten flywheel, upgraded injectors, and many other things im sure i left out..so as you see $1500 will not get you 160-190hp....sorry i know im a dream crusher[IMG]i/expressions/face-icon-small-frown.gif[/IMG] This is all the things i plan to do once im done with the interior and exterior of my car.

So, about how much does all this decking, porting, and polishing set you back? Anybody know?

LOWBOY

You would be surprised. Decking the stock head just raises the compression in the engine. (hense more power) As far as using new rods, pistons, valves, you dont need to. Although, when you raise the compression in our engines, you do need things like better fuel pump, use of 91 octane or higher, and new injectors.
Better be willing to spend over 2500, UNLESS YOU KNOW SOMEONE that works at a machine shop. [IMG]i/expressions/face-icon-small-wink.gif[/IMG]
