Performance Mods For Your Na Lancer/potential Gains/where To Buy

52 posts in this topic

Common topics I've seen on here are "What should I buy next?" and "How much hp will this give me?". Well here is the beginner's guide to engine modding in about the order it should be done, potential power gains (with other mods and by itself), and a few places you can buy them. This upgrade list is engine/intake/exhaust only, no suspension/tires/clutch/etc. All potential gains estimations are obviously product dependent, but still provide a rough estimate Feel free to add to the list or give edit suggestions. Note: I only included LEGAL modifications. Someone else can talk about things like a cat delete, but I'm not. When I have more time I will look into adding general install videos.

Intake

You have the option of either getting a cold air intake or short ram intake. Cold air intake has longer piping but will pull air from outside the engine bay, while short ram pulls the ambient air from the engine bay but has shorter piping. Lots of companies make intakes for the 2008+ Lancer. Injen, Takeda, RRM, AEM to name a few. Intakes aren't great at providing power, but combined with other modifications make for a great supporting mod.

Potential gains (by itself): Cold air intake 1-2 whp throughout the rev range, Short Ram 1-2 whp at the peak

You also have the option of getting a drop in performance air filter combined with a Ralliart snorkel. This will provide about 1 whp.

Exhaust

There are 3 main types of exhausts you can get: header back, cat back, and axle back. Axle back replaces the muffler and tip and is more for sound than it is for performance. Cat back and header back are the two more performance minded exhaust modifications. Cat back provides increased diameter piping from the catalytic converter to tip and muffler replacement, while header back provides a high flow catalytic converter also. There aren't a whole lot of options for pre-made exhaust systems. Injen and Greddy and RRM and Borla make some, and you can also find some on ebay. I'm sure there are others. Most pre-made systems are pretty expensive for what you get. The best bang for your buck is a custom exhaust system made by a muffler/exhaust shop, you can get twice the work done for half the price. The most common NA exhaust piping size is 2.5". You can get a 3" exhaust, which changes the exhaust note, but unless you are preparing for a turbo build I wouldn't recommend it. It reduces the back pressure too much, which will move the power band from the middle rev ranges to higher up.

Potential gains (by itself): axle back 1-2 whp, cat back 3-4 whp, header back 4-5 whp

Potential gains (with intake): axle back 1-3 whp, cat back 5-6 whp, header back 7-8 whp

Crank Pulley

A lightweight crank pulley doesn't create any horsepower, but it allows more power to be transferred from the crank to the wheels. Power is lost rotating the heavy stock crank, but by using a lighter material there is less power lost just rotating the crank. A lightweight pulley also allows your crank to reach higher revs faster. To my knowledge, right now only Alutec and RRM make these pulleys for our cars.

Potential gains (by itself and with other mods): About 2 whp

Header

Probably one of the better mods for the NA. The header replaces the stock exhaust manifold. Lancer owners have two options, a 4-1 header or a 4-2-1 header. A 4-1 header will shift power gains to the top end of the rev range, while a 4-2-1 header will increase power along the lower and middle rev ranges with a little top end increase also (not as much as 4-1 though). Supercircuit is to my knowledge the only manufacturer of the 4-2-1, while RPW, RRM, and OBX all make the 4-1 header. 4-2-1 is recommended for CVT owners, while the 4-1 is recommended for M/T.

Potential gains (by itself): about 3-4 whp

Potential gains (with cat back/header back exhaust): 8-10 whp
Potential gains (with axle back exhaust): 5-6 whp

Throttle Body
You can either install the TB from a 4g69 engine, or you can have your stock ported and polished. The 4g69s can be found on ebay or at junk yards. As far as I know there is no aftermarket TB, but I could be wrong. You will get better throttle response with this install.

Potential gains (by itself): 1-3 whp

Potential gains (all previous mods): 4-5 whp at peak, power band may not change much

Intake Manifold Swap
There are no aftermarket intake manifolds to replace the plastic manifolds the NAs were given, however the Evo X turbo manifold will bolt up. You will lose low end power, but will gain top end with this swap. You can also have custom manifolds made up, I know Wilson Manifolds will do it but I haven't asked other companies just yet. This is a mod I personally can't decide if it's worth doing or not.

Potential gains (Evo X turbo manifold): About 4-5 whp at peak, lost power throughout the lower range.

Potential gains (custom made): 3-6 whp? (unknown, don't know anyone that's tried)

Where to buy:
For Sale Forums or ebay
Wilson Manifolds

Camshaft upgrade
The best option is to have a custom camshaft made up specifically for you. I actually asked around a lot of places and got quotes for around $700. You can have regrinds made by Brian Crower. These cost around $500, plus the cost of 4b11/12 cams to regrind. The Evo X camshafts will drop straight in with no extra parts required (except possibly new tappets, depending on current wear). They are made for turbo application though, and even though they will provide power gains will not be as effective as custom made cams. All camshaft upgrades will require a good tune. DO NOT get the Brian Crower 272s without upgrade valve springs/lifters and cam sensor.

Potential gains (by itself): 5-8 whp (depending on custom made or Evo X)
Potential gains (after all other mods): 10-25 whp at peak, depending on Evo X or custom made and depending on quality of tune

Nice writeup,

Just to put emphasis on the exhaust line, You wont see the full potential untill every thing is changed from the headder (included) to the exhaust. What reduces the WHP is the restriction caused by the diameter of the exhaust line. If you change only from cat to tip or headder to tip, you still have a choke point being the headder's exit at 2.25". You need to have the same diameter all the way to have a good exhaust gas flow. Does this mean you wont have gains with just the exaust? YES you will have some gains, but NOT the full potential. Be carefull also when you buy a 2.5" headder, for example OBX headder is a 2.5" but has a choke point where it bolts to the exhaust because they wanted people to be able to bolt it to the existing exaust. That means it reduces to 2.25".

A cheap mod to do, is a Hi flow catalytic converter (cat), even on you stock exhaust, you will have gains...But unlike Blizzard25, I dont have estimates but from previous cars, I know it does make a difference because exhaust gases flow WAY better...

But he is right, dont do a cat delete, its illigal and the ammount of the ticket you'll get could very well be the amount you saved by putting a cat delete instead of a real exhaust...NOT worth it...

If you have to ask that question - a 4G69 TB swap would be the easiest and most cost efficient upgrade.

Not trying to chirp you - it's just findin someone that can properly port and polish a TB ain't gonna be cheap.

The 4G69 swap is a tried and proven swap

Thanks

Will the factory intake fit on the 4g69 throttle body or do you have to modify intake? I have takeda sri.

Check the original post. You can get them on ebay, an e-junkyard or real junk yard, or buy them on for sale forums. I believe RPW might make another throttle body, I'll check and if they do edit the original post.

Thanks. I included a little bit about a high flow cat in the header back exhaust part, but there's actually been some evidence that high flow cats don't provide much improvement from stock. I remember seeing someone doing testing, and he only saw a 1 whp gain at the peak. But a 1 whp gain is still better than a 0 whp gain.

It is possible...but its a cheap mod, I've being doing it on V8 engine where the increase in HP would maybe be more noticable. I know this thread is about HP but it does change the exhaust note, the reason why some would pay 300$ for an axle back exhaust in the first place and have the same increase in HP...Hi flow cat...can fnd one for below 100$ lol

Ha i guess I see your point. While I only have a cat back right now, if I do anything I'll probably just replacing the piping from the header to cat. I don't really car about sound too much like others do.

You forgot two things :

Ralliart snorkel (direct swap). (Not even maybe 1-2 hp but more airflow to NA )

Cooling panel ram cut out with air ramp. (Maybe 1/2 hp but more airflow to NA = better throttle response)

Ralliart snorkel is already in the OP (check "Intake") along with a drop in filter, but the other one I did forget. Thanks.
