I'm currently running an AEM CAI, DC Sports JDM ITR 4-1 Ceramic Header, CarSound High Flow 2.5" High Flow Cat. and 2.5" piping w/ Resonator on my 2000 Civic Si and I'm wondering wht kind of gains I'd see by adding a Skunk2 Intake Manifold, Skunk2 Stage I Cams, Civic Type R Crank Pulley and an OmniPower Test Pipe. Noticable difference? what kind of hp would I gain and would I need to go with a larger throttle body?

My second question is a buddy of mine just bought a Shark Racing ReMapped ECU for his 2003 Tiburon and he says he got a noticable difference out of it. I'm wondering waht the equivalent of that would be for a Civic Si like mine? Hondata? or what just to tune it a little and pick up a few horsepwer like he did.

Waste of money. You'd get 5-10WHP. The 1.6L doesn't generate enough torque to move such a heavy car. Move to a 1.8/2.0L block or turbo the ******.

A chip won't do much, a hondata tune will be at least $500 (for parts and tuning), and you'll gain at best 5HP. Another waste of money.

Start looking at snails my friend.

 

Uberdata+turbo best budgeted hp for what u have under 1k if you look around

 

Anyone else have any other comments or suggestions? How about the OmniPower Test Pipe in place of my CarSound High Flow Cat. that's shot? Will that help out some at least? How about Ignition upgrades for some added response/power? MSD 6A, SS Blaster Coil and 8.5mm wires? I need more help than that guys....

 

First of all, your exhaust diameter is a little too big. For a 1.6 liter motor, the recomended diamter is 2 in. For a turbo, add a quarter in. Without some back pressure in the system, 4 cylinder motors dont run right. I would suggest ditching that high flow cat at least and returning to the stock one. Other than that, I would get an adjustable fuel pressure regulator if you dont already have one. The stock fuel pressure is about 37psi and can be lowered significantly depending on your altitude. I live at 7000 feet and was able to lower the fuel pressure to 23 psi to lean it out. I found that this was the best way to increase horsepower if you have a full exhaust and intake. Just make sure that you have an air/fuel ratio gauge to monitor the mixture. the regulator should run about $50 (B&M regulator). You will also need a fuel pressure gauge to know how much you are increasing or decreasing fuel ( mechanical gauge mounted on the fuel filter). I hope this would help you as much as it helped me, but at the high altitude that i am at, my civic was running extremely rich and leaning it out helped a lot.

 

for computer management, look into the APEXI VAFC air flow converter. this computer alows you to set the vtec engagement and disengagement points. also, it allows you to re-map the fuel system for optimum fuel management. It will have several different presets for preset fuel maps of your choosing.

NO NO NO NO........that is a bad idea. it does let u do vtec engagement. but it dosent work well

 

if you know what you are doing and get the computer dyno tuned, the computer can do wonders. most speed shops will dyno tune the computer for around 100 bucks. that is proven power with the right parts.

Of course a larger block will give you more torque, and yes these will maybe give you 10whp, these I won't argue, but it depends on how my overall money you plan on spending and what your goals are, as always.

Turbo will eventually be the way to go if you want big power, but ultimately, as Bauley stated (in a not-so-clear-manner) there is no replacement for displacement.
