Supercharge/Turbocharge 350z?

Im looking to either supercharge or turbocharge my 03' 350z but still cant decide which one i should choose. arguments on both sides are good, but as of right now i am leaning slightly towards supercharging becuase they are easier to install and maintain. Although the possibility of eventually running a twin turbo seems good too. Any tips/advice on which i should choose would help alot.  

Well with turbo's they do have the turbo lag as you know, But during a certain RPM they can give you great power, you can also change the boost as you see. The Supercharger does give you power through out all RPM's, The boost on them is pre-set with pullies. The Supercharger is easier to install and maintain and does look great, The have quite a whine and the turbos just have a whistle and it is really up to you. Twin turbo Z33 would be great though.  

What? ^  What is a Z33?  Superchargers look good?  lol....

A friend of mine is planning on putting a twin turbo setup on his future 350Z.  Yes, turbos lag, but everyone takes that as a bad thing, when it's really not all that bad.  When driving on the street, you can turn the boost down and get very reasonable gas mileage.  And with a different ignition map, you can hike up the boost and get loads of power....  Something you don't get with supercharging...

honestly this usually isnt an issue i consider when i post but with the economy gone to hell the turbo would be a much better choice.  plus supers look like hell on 350s.  check these links out.

I am curious to know what you went, and the result as i am also trying to decide what i want on my z33, thank you  

Even thought the orignial thread is quite old I'm just gonna answer it from here and I'm going to try to make it as easy as possible to understand since forced induction is quite possibly the most misunderstood subject on modifying a car. On the argument on super/turbo scenario try to imagine it this way. On a regular roots type or manifold placed supercharger most of the power is from low to med RPM and yes supercharges have some lag since they require the screws inside to spin to a specific rpm to make boost, they just do it a bit quicker than turbos. That means that the pulleys creat load on the engine which is like having the A/C on. on very low and very high RPM the engine is working more that what comes out and superchargers cannot achive more than 60 percent efficiency. Now a centrifugal supercharger only makes power on the high side of the rpm range so unless you got a very torquey engine that makes lots of power down low, but up top everything dies out this setup works for you.

On a turbo charger most power comes out at around 3000 rpm because of lag, but the power range continues well past the 5252 rpm range which means you got power even after the curb. For a 350Z HKS makes a superb supercharger with internal gears which pumps out power specifically when the engine needs it and it is quite the most advanced supercharger available, but it cost around 7k. If we put it into context a Jim Wolf Technology twin turbo setu runs for about the same price and the HKS makes around 380-400hp while the JWT makes it to the 500hp range on stock internals.

Now I'm not gonna lie. I had a stillen roots type supercharger on my old Z before I wrecked it, because of the same arugment it was cheap. I got the stage 2 (i hate those terms "stage") because it was internally intercooled, and because of it; it also came with a warranty. It was pretty fun even though it was no match for them boys with modified evo's
