07 Hyundai Accent Engine tune help 1.6 L CVVT Alpha II I4, 112 hp

[Glock23]

I'd like to know what I can do to my stock engine to get more power. I know I can install headers and a exhaust system but past that What else can be done?

I must also state I'm a moderator for a hyundai forum dealing with accents and we have yet to find anyone who can tell us what we can do to our motors.

Please advise so I can help the rest of my community. (about 1000 wanna be tuner members )


My past cars:

99 Caddy STS 31V northstar

94 Impala SS Lt1

85 Ford Bronco 351w

I don't want to be the one to do this but this forum is NOT for Hyundai vehicles, you'll have to search else where for info on them, unless of course, your doing a 4g63 swap!

You could go to Hyundai-Forums.com and look there sense this is a "DSM" forums.

It's the same goal for all gasoline vehicles, improve volumetric efficiency. In other words, find a way to fit as much air into each cylinder with each combustion cycle. As you stated, an intake and exhaust are often a good start as they are often bottlenecks from the factory due to the manufacturer's focus on NVH. Past that you will likely need to look into ECU tuning / reflashing or aftermarket ECUs to control anything much more than the vehicle was designed for. After that, I'd say look into cams then consider forced induction or nitrous. Then again, being able to choose your own route when modding a car is most of the fun.

Id say that a nice nitrous kit with a proper setup will net you some nice gains. Your options are limited unless you look into some crazy swap...(cough) 4g63

Well, from doing a quick search, I was able to piece together the fact that the only REAL factory part upgrades for your car is an air intake and an exhaust tip. Not too much from the factory side. Lets look at the other side.

0-60mph = 10.8 seconds
Top speed= ~120mph I am guessing it is drag limited and not ECU limited....

Question. Are the 1.6L Alpha I-4 and the 1.6L Alpha II I-4 the same engine block? The reason I ask is because there was a rally program for the 1G and 2G Excel's in Australia, you could look there for answers.

Aftermarket wise, I was only able to quickly find head studs, a clutch and a header. Not lots of options here.


You are really going to either find a custom swap to put a better engine into your car that has a better array of aftermarket parts available, or you are going to need to get custom pistons and rods with a lower compression, along with a better head gasket, and then piece together a custom turbo setup.

Even with that said, I have absolutely no idea what kind of capacity your engine can handle in stock or modified trim, let alone the clutch or transmission or axles, etc.

Nitrous will be likely the cheapest way to make power.


Either way Turbo, or nitrous, you will need additional fuel via larger fuel injectors and a larger fuel pump (install a custom in-tank Walbro 190 or 255 fuel pump or even easier, run a Walbro 255 fuel pump in-line for additional fuel capacity).

Do you know how large your fuel injectors and stock fuel pump capacity is? Are the fuel injectors top feed or side feed? Are they low or high impedence? What kind of plug? Dimensions? (A picture along with the impedence and current size will help substantially).

You will need a rising rate fuel pressure regulator if you are going to run a turbo setup. As well, you will still need some type of tuning program or piggy back controller to compensate for fuel adjustment; especially if you are turbo-charging. Look into wiring in a custom Greddy E-manage for turbocharging applications. You might be able to get away with a S-AFC for nitrous control -- but not likely.

You will also need to find colder plugs than stock; at least 1-2 heat ranges colder. The stock BKR5ES-11's are a really hot plug. You will want a BKR7ES, which is the NGK Part Number #6097. Your stock engine gap is 0.044" for the stock plugs. You will want to gap your BKR7ES for around 0.028"-0.032" this will substantially help with detonation on either nitrous or turbocharged applications and are a direct fit for your car.

Is your vehicle utilizing a MAF or a MAP for air flow measurement? If it is MAP, you could run a AEM fuel/Ignition controller (FIC); (NOT THE AEM EMS; the air/fuel controller is much less expensive and is a universal controller for boosted cars that came N/A -- glorified S-AFC but with some nicer controls), and could utilize a larger MAP sensor (if this is your sensor type used stock) and install a Air Intake Temp Sensor (AIT). Then, you would be able to set the car up for a boost compensation map that will properly work if you are using a 1:1 pressure rising adjustable fuel pressure regulator and larger injectors with an aftermarket fuel pump.



You are still stuck on cams, exhaust manifold (it will need to be custom to do a turbo one as the European 1.5L Alpha motors are the only ones that came turbocharged in diesel form), intake manifold (look for a swap among other ALpha engine cars worldwide), throttle body (again, look for a swap, or modify an aftermarket one), etc.

If you are going to boost it, I would strongly suggest ARP head studs and to contact a quality head gasket manufacturer for an aftermarket head gasket that can handle boost for your application. Contact Cometic or SCE.

Your ignition system is also likely not up to handling boost. Look into the higher voltage Alpha diesel coil packs, or make your own aftermarket ignition system, or wire in a MSD box or equivilant ignition controller.



Good luck with your endeavors!

I do most of my DSMtuning on the Skoda sites.

What the hell, is the fence down again?
