Hey guys, I am looking to do more to my 03 G35 coupe - but I’m not exactly sure what to do. I am looking to make the car faster and handle better. So far I only have a Godspeed catback Exhaust and a cheapish cold air intake. I’m wanting parts that work efficiently but aren’t hundreds or thousands of dollars. Please help.

 

Whats your budget?

 

Where are you located?

 

I don’t really have a budget at the moment, just getting an idea of what to get. As long as it’s not thousands of dollars I’m all good

 

I’m located in Southern California

 

Sadly there aren't many mods worth a **** that won't cost several hundred dollars. In your position though I would recommend:

Getting rid of your intake and putting the stock set up back on with a free flowing filter. Intakes lose power, they don't make it due to heat soak.
Motordyne plenum spacer-$250
HFC's or test pipes-$150-400 depending on brand
Motordyne or Hotchkis sway bars-$350

The sway bars will completely change the handling dynamics of the car and the HFC/test pipes combined with the spacer will free up the major restrictions in your exhaust allowing the motor to flow more freely and generate power. Sadly though you might gain 20HP at the most without a tune with your exhaust and these 2 add ons. Your car won't make significantly more power until you supercharge it or go the turbocharger route.
