I own a 2001 Maxima and so far I've done:
Strut and sway bar
Intake, Ypipe, Straight pipe, Greddy Evo cat bat, Flywheel and short shift kit. Soon it will be lowered.
But I need more power, I'm against the underdrive pulley cause i want to do a supercharger or a turbocharger.
What other bolts ons can i do. I'm leaning towards the supercharger because it easier to maintain from what I heard. Besides Stillen what other superchargers are out there?

 

Try this link.

 

Remove the power valve in your intake manifold for awesome top end power

 

will that have any ill affect to my car

 

You may (or may not) experience some loss of low end torque. If your VIAS is functioning, I don't know that you'd see a big difference at either end. If your VIAS is broken, you can either fix it or remove power rod. Since neither is difficult or permanent, why not try both?

Another opportunity to pimp the VIAS Fix!

 

I don't want to risk losing low end power

 

Have they developed a throttle body for the Maxima yet

 

what about headers??

 

I heard headers aren't worth the money for an 01

 

but you want more power. Your gonna need every little bit if you want to extract it out from this engine.

and besides stillen there is no other SC available. You'll see the gains you want with SC+headers

 

That's not true. You should also get a set of lightweight rims, that's a huge performance gain there. And there are valve body mods available for faster shifting.

 

You may want headers if you're thinking about supercharging. Of course... you can't use them if you go turbo. As for the expense, the Cattman headers are pretty nice, but they seem really expensive. Hotshot is a reputable company that makes a lot of Nissan parts, and their headers are nearly half the cost of the Cattman headers, but they are still made of high quality materials, and the design is very similar.

I know it says it's for an 02-03 V6, but aren't the exhaust manifolds nearly identical on the 01-03? If these headers won't fit an 01, somebody please correct me.

 

i want to get headers but i want to go turbo so nyeh

 

you could just get another car...one that already has more power
