Hi all.....

Just bought a 2007 2.4 manual with only 51,000 miles....like New condition one owner garage kept.....
Would like to add about 20-25 HP or so...nothing crazy.....on a tight budget.

What performance mods would YOU do if it was your car with limited $$$??

Thanks!
Jerry

I dont think that it can be done with a 2.4.

GXP dual exhaust bolts right up, you just need to buy a GXP rear valence that has cut outs for dual exhaust. People sell the exhaust all the time - I have a set for $100 located in Denver. It wont give you much performance, but it makes the car LOOK faster!

Saveaux is correct. You cannot add power to the 2.4 without spending serious money.

I have read that a CAI will give better throttle response, but I think that is illusion due to the increase in noise.

The best performance mod you can make is to add a DDM ProBeam. No single thing will make a more noticeable improvement.

I added CAI. No improvement in performance. In fact, it's not even true CAI. It takes air from the same spot the factory intake did. (it does look good, though)

Ok, Thanks John.

What about a engine tune?
Is there a "stage 1" or "stage 2" engine tune for more ponies on the 2.4 for a few hundred bucks or so?
I know a "chip" is worthless.

You get very little on a 2.4 with the tunes, although some have reported improved drivability. I know that some NA owners have some trouble believing that given all the tuning talk about the turbo cars, but they are two very different situations.

I second John's recco of the Backbone and suggest that any other money go into better/newer tires.

Ok...I can live with the 177 HP......still fun to drive and when I shift at 4K or a little higher it keeps the power up there.

Still might do a CAI for some engine bling and little more engine growl.

According to the well known places like DDM and PAW their tune gets you some more oomph.

For instance PAW their tune will ad 10hp and 10-15ftlbs torque

can't really tell because I have the Solo catback center exhaust which pretty much overpowers, sound wise, the CAI. Did that also for looks alone. along with Norm's center exhaust fascia.
I agree the NA engine is fairly non improbable. The most performance improvement mod, in my opinion, is a set of high performance tires. Good tires can completely change the car’s handling.

Most owners that have "tuned" their N/A have indicated the most notable improvement is taking the "nanny" off of the throttle. You get a bit quicker response from the peddle. Beyond that, not a lot.

Be like me - turn your HVAC controls on high through the dash vents and it feels like you're going faster.

Within the realm of sanity on a public road, the NA can go as fast as a turbo. It just can't do it as quickly.

Get a ProBeam and a decent set of tires, and enjoy the car for what it is: Great handling and great looking.

And blow air in your face with the dash vents.

You asked about adding hp, but as others have stated, theres opportunity to increase the handling, quite dramatically.

Tunnel Brace - DDM or PAW
Pro-Beam - DDM
GXP Sway Bars
Venom Brace - DDM
Coilovers - BC Racing
Brake pads - EBC or Hawk

Mods that I personally like:
-Short 3-5" antenna
-Black front headlight mod
-I Like NA's that have black grilles instead of silver
-I love my tempered glass windscreen
-Tinted windows
-Kappa Blanket (cover to protect convertible top while its in the trunk)
-remote trunk opener mod
-remove badges as you see fit
-drilled/slotted brake rotors
-double din stereo with backup camera

Looks Great!

Thanks for the replys folks!

This car rides stiff enough for me so I think I'll leave the suspension alone......It's a fun little ride as is, I was just curious as to what I could do to add a few ponies.

Unfortunately, additional ponies aren't a reasonable option.

The ProBeam is the one suspension mod that is all upside. It does not add stiffness, but does improve stability. It will make driving on the twisties more enjoyable.
All of the others increase stiffness, decrease comfort and, based on my experience and some back-to-back testing, can actually make the car slower.

Agree, Too stiff shocks can have the car stuttering sideways across rough pavement instead of sticking to it. There is an unfortunate tendency for owners to dial in far too much shock stiffness (because they think it is 'racy'? I don't know).

The stiffening mods that increase torsional stiffness of the chassis, on the other hand, settle the car in a corner and allow it to stay planted. I noticed the difference immediately when I added the Probeam.

Tires.
Aftermarket exhaust will add a few ponies but only WOT and above 5000 rpm, but adds a nice sound. Solo or MagnaFlow. Still usable if and when you supercharge.
CAI is the same, only improves max HP, and is a loss if you SC.
Ditto all the comments on suspension. Opportunities to corner hard are as abundant as opps to accel hard and equally rewarding. And stiffer chassis and anti-rill bars do not stiffen the ride.
