Hey guys i need some pointers on adding some good horsepower to my 2004 g35 AT?

 

5/16th Plenum Spacer $200
Z Tube $70
Performance Air Filter $50
Test Pipes or High Flow Cats $100-$700
True Dual Catback Exhaust $500-$1500
Osiris Tune $500-$700
Transgo Shift Kit $500

Add labor costs too. These are the best mods for your car for power/performance if you plan to stay N/A. If you go F/I then start reading everything you can now and plan to spend A LOT more money... A LOT!!

 

Forced Induction for any real gains...that is all.

 

LS V8 swap.

 

How much would that cost?

 

Everything AzuMaster listed + 3.69 diff

 

bout $5.

 

after all that get ready for a whopping 20-30hp increase lol. nah idk . close tho

 

get a 4.5L stroker.

 

Research Vortech

 

Basically everything said above

Please ask this question on my350z in the FI forum...lol

 

Define "good" horsepower. Like this?

Motordyne spacer is the best bang for the buck mod N/A. After that just sit tight till you're ready for FI!

 

Don't forget about the aftermarket driveshaft.

 

40-45 to the wheels, lots of info and results like this in the Osiris Tuned Dyno thread. Thats almost a 20% increase plus much better throttle response and a wider power band. If the OP is looking for much more than that he should have bought a different car. Lolz
