Default How can I make my 2003 Honda Civic faster?

I have a Automatic 2003 Honda civic Lx. How can I make it faster and what are the cheapest ways to do it. I need to add more horsepower to this car because this car is just way too slow. Give me several options.

one thing i did is i bought a resistor about 1k resistor, and place it in the IAT sensor, this will add 25 hp by making the car think that the weather is cold, and that will cost you 25Cent to do,, and how much do you want to spend?

you could do a cold air intake setup, a chip, a nice catback exhaust setup, a cooler t-stat, some high performance plugs and wires

Vahe,















































There are a few approaches to answer your question. You asked for the cheapest, which is different than the best bang for the buck.































The best bang for the buck approach is to implement a turbo or supercharger kit, like those from Greddy and others. If you know what you are doing, you could even create your own kit, though you run a zero percent chance of it being smog legal.































The cheapest way to make your car go faster is to upgrade it component by component. This is the route most choose, because it requires investments over time.































My first recommendation is all of the obvious stuff: Reduce the weight in the car by removing unnecessary items and stripping the interior. Find some used rims that are light too. If you search for used parts online, you should be able to find some 15x7s that are around 10-11 lbs. Its a cheap upgrade.































My second recommendation is to get a Kpro. Yeah, its $1000, but you arent going to be able to take advantage of engine modifications without it (like all of those cold air intakes, headers, and other engine mods).Be sure you get it tuned, or do the datalogging yourself and tune it.































Third, before you consider doing drastic things with the motor, pick up a header and cold air intake. It will reduce the weight of the intake parts, allow the engine to breath easier, and will lean out the fuel to air mixture, which you will adjust with the Kpro.































Anything beyond this will require some serious modification... A good bang for the buck upgrade at this point would be to change the head to an EP3 A2 head. It breaths a lot better and can improve power quite a bit.

not much you can do with a d17a1. wiring resistors into your iat will just piss off the ecm. a head from a ep3 k20 will not fit- they have timing chains, you have a belt. intake systems will NOT lean out your air/fuel ratio, this is determined by engine rpm and manifold pressure. it will allow more air in, but the ecm adjusts for this. and spending a grand on ecm tuning is money better spent on an engine swap. in short, these are nice, reliable cars, but not a great candidiate for speed racer upgrades.

Well it depends the power you want to achieve. You have some great answers above and i will agree with what everyone is saying. Want a few more HP . get a set of DC 4-1 Headers. AEM cold air intake and maybe go for an Apexi full exhaust and chip your ECU. Keep in mine full exhaust will run you $500 and better. This is will be relaxing but a better boost of HP































i DONT RECOMEND BOOSTING AN AUTOMAITC. you may do whats listed about but ifIf you go all out and want to go boost go for a t3/t4 turbo. But you will definaly have to build up your internals. def go for 550 Injectors and just completely build your block for boost.. this will be a heavy mod so have your pockets ready..































boost doesnt work well on auto's. Automatics want to shift through the gears too quick and wont allow the RPM's to rise where they need to be















gl bro let us know what you eventually do

You Could Do an Engine swap and or add turbo kit.































Engine you can go for are.















1.H22A















2.K20A































Have best torqe and Performance,















But the H22A is much cheaper Then K20A































Turbo you can go for are.















1. Universal Turbo Kit "found on ebay This one you can run stock "















2. HKS or Greddy "If only you change all the parts in your engine first if you don't want to bust a piston."































But Most common that people do is,































Add Exhaust and intake system.































I Hope that can give you an idea! ^_^
