i need every ones help please?please??
 

i am looking into doing some internal engine mods to my kia sephia 2000, im looking into doing a port and polish and gitting an ingtion system is this combination a good idea?im basicly looking for the best bang for my buck so if any one here could recomind any other type of internal engine upgrade it would be greately appreciated?or would something like a computer chip and a header be a smarter idea?

any other ideas guys????

bang for the buck is not engine work dude.

you'll need to find a REPUTABLE tuning shop with lots of experience to do that kind of work for you.. also.. it will not be cheap in ANY form of the word.

if you want the maximum power from your car, without even chaning the stock muffler... take the car to the BEST NITROUS TUNING SHOP in your area.. and have them install a wet nitrous kit single fogger setup.

it should be less than $600 installed by a reputable place.

and dont let anybody convince you to use the dry kit. Dammit I hate dry kits.

every other week someone else is complaining cuz their damn vacume lines pop off and their motor blows up.. or their stock fuel pump sucks butt and it wasnt strong enough to handle the juice and same story.. BOOM BOOM engine.

I don't run a wet or dry nitrous kit and have no plans for either, nor have I done any serious research. But I recommend you do before you take any steps into this territory, from what I have seen the reward comes with significant risk.

I don't mean to disrespect FordFasterR, but he's starting to sound like a wet nitrous bible thumper. When someone chants the same mantra that often it comes off as fanaticism and earns a large grain of salt in my books.

Nitrous is steriods for your engine. If you're willing to take the risk, go for it. But be aware that the ultimate cost may be a complete rebuild or replacement of your engine and complete void of your warranty. If you are really worried about your cash flow, keep this in mind. There are other relatively cheap mods that can give your more power, but power always comes at a price.(oooh, now i'm a philosopher rolleyes.gif )

Cheap, easy, and almost risk-free is a cold-air intake. Search for that or CAI in this forum. More expensive mods that complement this are to go for a larger or bored-out throttle body and intake manifold. Someone else may be able to comment on the suitability of the Kia engine for this, but enlarging the bore of the stock TB and manifold is really a 'stealth' mod, it is almost undetectable by a dealer trying to void your warranty or deny service. alone, his may be able to get you maybe 5% to 8% more power.

A high-flow exhaust system, starting with performance headers and through to a high-flow cat and performance muffler can usually gain you up to 10% more power if done right. Coupled with the intake mods this will gain you a fair bit.

As for chips or ignition upgrades, these don't usually provide a lot of benefit until you move well beyond the stock power range. The computers in modern vehicles are relatively adaptive and will control your mixture and timing to a pretty good level until you have put some serious modifications into your engine.

And having said all that, others have more experience in this scene than I, I will gladly defer to their suggestions. smile.gif

Good luck

Intake, Exhaust, Sticky tires, driver skill

These are the things you only need! :D :D :D

It depends on how much money you have to spend, and how much HP you are looking for.

If you are looking to add another 50 to 75 HP, for under $1000. Then Nitrous is the way to go. I reccomend you do your own research on the subject and make your own informed decision as to who's kit to buy, and how to install it/have it installed.

If you are looking for more power all the time, then minor modifications, a bit at a time is/are the way to go.

A CAI you can build yourself will run you under $100.
Boring out your TB and intake manifold will help. Then headers and a decent exhaust system. Once that is done, you should have gained about 15 to 20 HP, and THEN you would be looking at internal engine mods such as port work.

To the best of my knowledge, there is no "chip" or ECU replacement for your motor, however, with the above mods, a properly dyno tuned S-AFC should do the trick.
