I realize that this has probably been asked a thousand times....but.....Here's the situation. I am looking for the best mod for the money. I want more power but dont want to spend more than 5-600 dollars or, most importantly, void my warranty. What is out there that will give me a little more power. I already have the Stillen SS Exhaust and the AEM cai. Thanks!!!


One more note. Does anyone know about getting an X-Pipe for the Z. I dont know anything about this exhaust system but love the way that X-Pipes sound on some other cars. thanks again.

 

High flow cats/test pipes or plenum will be your best bets with the mods you have and with the $$ u are looking to spend.

 

i also say plenum or test pipes

 

wtf is an x-pipe? dont you mean y-pipe?

 

best HP for the money and something you can remove for warantee work would be NITROUS!!! by far the best HP for $

 

1) Nitrous
2) Pulley
3) HF Cats or Test Pipes
4) Sun Automobile Hyper Voltage System

 

STILLEN EXHAUST HAS AN X-PIPE!

 

hmm...stillen has x pipe. i thought so. i discovered this while researching earlier this afternoon. i bought the car with the exhaust already installed. i had no idea. so, with that said, would high flow cats be an option for me? are headers not a good power improvement? also, does the pulley not void the warranty? thanks again for your input.

 

Yes, high flow cats or test/race pipes are an option. I believe ALL exhaust systems for the 350Z go only to where the stock cat connects to the rest of the exhaust (cat-back).

My recommendations are:

1.) Nexus/Alphawerks Headers (over 15hp and 10tq gain with other mods)

2.) La Bree or Unlimited Tuning or Kinetix Resonated Test Pipes

3.) Unorthodox Racing Pulley Kit (I believe it includes a U.R. belt in it)

4.) Z-Extreme.com Grounding Kit

5.) Crawford Intake Plenum

Choose whichever of those that will fit in your budget.

 

in this order:
Pullies
plenum
sways
test-pipes/cats

 

JWT Pop Charger and UR Crank Pulley

i'm actually in the exact same position as thin guy, except the x pipe part

 

If you want a little more cheap power, your best bet is resonated test pipes or highflow cats. Nissan350ZTT came up with some good names. Add Crawford's highflow cats to the list and avoid Random Technologies highflow cats.

And, consider getting rid of the AEM and replacing it with a JWT Popcharger. There are airflow issues due to the twisted lengthy piping with the AEM per Crawford and other noted forum members.

 

Does the pocharger actuallyt improve anything when compared to the stock intake? I heard rom someone that they actally felt like they lost some HP. Whats the lowest price on one?

 

This thread comes up about once every 3 weeks.

cats/test pipes
plenum
pulley
nitrous

are probably the BEST mods for the money

popcharger is a good one too, but you'll hear it more than feel it

two mods that make a big difference too, but need to have their pros and cons carefully weighed are the 3.91 final drive and a lighter clutch/flywheel
