Recently I bought a new Mazda 6i 2.3L and I'm looking to add some horsepower to this baby. Whats the best way to do this? I've considered performance mod chips and possibly an Ingen air intake system. Any recommendations?
How can I increase HP in my 4 Cylinder

given i've had pretty much everythign on the car at some point i'll try to chime in. first off, 2.3 covered, but MTX or ATX? makes a world of difference. my opinion would be to bypass the CP-E and go with a AEM/Injen and get a scanner...you will probably have enough left over to free up some of those bottlenecks in the exhaust at a muffler shop as well. after that, wheels and tires are going to make the most dramatic improvement. then there is the flywheel (flywheel) or valvebodies (atx) to make it a bit more spirited. and there's always the $30 balance shaft removal kit, now made by Cosworth. I still have the F2 headers sitting in my garage, he's supposed to pick those up from me soon. And CP-E might have something coming in spring if you wanna wait for that. outside of more suspention stuff, that's about it in the pricerange you've put out there. keep in mind install cost if you go with flywheel, valvebodies and balance shaft are cake so no worries there. hit me up if you have any other questions.
also, what kind of driving you like doing, that can make a difference as well.

i really like the combo of the balance shaft delete and the valvebodies. it's a days work if you can turn a wrench. Hit up Lentech about the valvebodies (350 or so before core i think), and they can also do a new torqu converter if you want, but that is a more involved install. BS shaft, i'll have to look for the company selling the cosworth piece, or you can look on the mazda3 forums or focaljet as they have posts on it as well.
Both of the inakes CAN throw a CEL, some have been over a year without, some don't make it out the driveway. you can get a scanner from many places, just make sure it's CAN cabable. i'd start in the group buy section, usually something going on there. but that way you can scan the car every week/day if you want cause of a CEL, and if something comes up down the line you already have the needed tool.

Doncha guys just love the "I own a Mazda6 and would like to know how to increase HP" threads? 
Brings out the best of us. CP-E and the exhaust is the affordable choice. You might think that the exhaust doesn't give much power, but with the noise it makes, it sure does make it sound faster! Flywheel upgrade may be a bit on the tech part for the newbies.

You might want to find someone locally who has an exhaust setup on the i4 before purchasing. I personally dont like the sound of cat-backs on the i4.

To get more power from exhaust mods try opening up these restriction areas:
![Image]()
Just opening these up makes a nice difference in the high RPMs where it now pulls progressively stronger right up till the fuel cutoff.
Quiz: Whats wrong with the pipe sizes in this picture-

An exhaust shop can do it in about 45 minutes. ($60-$80) Just find a place thats familiar with performance exhaust setups and they'll know what to do if you can show them what problems you want to correct. You can pull the cat (just 4 bolts...) and use a pipe expander and honing tool w/ electric drill to smooth out the choke point there.
Here is the front section 'cleaned up' with 2 1/4" pipe installed:

Since these pics were done I've installed custom made mandrel bent 2 1/4" pipe for all the pipes in the system including the rear split. :drool:

Can v6 do this mod?? I think the system is somewhat different.

The mufflers, resonator and cat are all stock, but all the pipes and connections between sections have been optimized. As is, it's a little deeper and just slightly louder than a completely stock setup.
The V6 is very different in the front where the headers, pre-cats and cats are. From the resonator flange on back, I believe it's the same system. There are diagrams of the V6 system posted in engine/drivetrain section.
It looks rather ricey.
We should have a thread called 'Rice Mods', a collection of the riciest mods ever made on a car (Mazda6 or otherwise) :laugh:

Electric superchargers are not "ricey". They work and work well for their given purpose. Correctly set-up they offer reliable forced induction that is fine for day-to-day driving and gives a moderate power increase for a reasonable pricepoint.Originally posted by Faz105@Nov 21 2005, 12:19 AM
