Hey guys,


I have a 2003 350Z with about 85 000 miles on it, Iv had it for 4 years and always maintained it extremely well. I am considering buying a brand new Vortech supercharger kit.

The mods on the car are a true dual exhaust (Invidia Gemini Catback) a Kinetic v+ plenum, intake and underdriven pulleys.

I've heard nothing but good things about Vortech superchargers, expect maybe a ratteling noise on idle... has this been fixed with the V-3?

Its also a high millage car, could that be a problem?

Any personal experience (good or bad) with those superchargers are also welcomed.


Thanks.

One question answered. I will do a compression check. Thanks for the link.

I found this thread to be extremely helpful, I recommend it should be posted as a sticky at the top of the forum!

Haven't seen anything (in the pages iv read) about the idle noise, anyone has anything to say about that?


EDIT: Need to raise idle to 1000rpm.

Lesson learned: I should have used the search button within the thread.

Someone can either lock this or turn this thread into something entertaining.

I love mine, its perfect for the street. Ditch the underdrive pulley though, its counterproductive when you add a S/C. No rattle noises with my V2, just the typical (Hey look at me!) whine at idle. You shouldn't have any problems at all with your mileage, just get a good tune as anybody should, mine is no spring chicken either. Overall I'm very happy with the characteristics of the supercharger, and will not be going to a turbo (I had a TT Z before as well). I recommend getting the car tuned on Uprev by R/T Tuning in PA (they are a sponsor on here as well), and you won't have any drivability issues.

i wouldn't have gone the same route if i'd do it again. i'd ditch the car, go for something more powerful. cuz spending 20k just to reach 400whp (and that if i does) is just too much.

You spent 20k to get to 400whp with a supercharger setup?

maXmood

iTrader: (16)

yes, and that if it does hit 400whp. (engine still to be built). i'm not saying just the supercharger, but the project of FI'ing the car (which includes all supporting mods as well)

basically my setup only put me @ 305whp, and now putting alot of $$$ into the engine just to get it to 400whp (i hope it does).

I'd look into a new tuner if I were you. If you only made 305whp with a 2.87, and are building the motor to hit 400, there is something wrong. My setup is with the 3.33, a VERY conservative tune for daily driving, and the stock motor, and it put down 392whp. The car made over 400 with a little more aggressive tune, but he backed it off a bit. There are people getting close to 300whp on NA setups these days, so something is wrong here.

my tuner is well known in my area, he knows his stuff. he tuned many Zs with high numbers. alot of factors that probably made the car produce that much, including weather, fuel available, and not forgetting my motor which only output 210whp when it was stock.

I was planing to use the SS box and do the work myself, I was under the impression that this would be just fine since it only compensates after the ECU can't take it no more.

You can blame all of this on a S2000 who managed to pass ahead of me (3-5 feets) on the highway, while it's true that I had my GF on board and some stuff in the trunk my Nissan sole still took a beating.

20k>? you can hit 400hp with a vortech full kit ,3.12 pulley an an exhaust. way below 10k

How did you spend $20,000 supercharging a Z? Or is that in Bahrain money?

for whoever is talking about spending 20k for a vortech setup then they are just plain retarded and cant do a thing themself and just buy things they dont need or made mistakes in a big way, dont spread stupid useless info to people who might actually beleive it takes that much...i spent no more than 6k total between buying the kit and i installed everything myself and then had it tuned at vinny ten.. i made 420whp/355ft. lbs with the 3.12 pulley and other bolt on's and a bad *** tune...my car turned good times and held up very strong and was a great street car, recently parted out ...i have no complaints with the vortech kit at all..its a great kit for someone looking for quick street car and nice for a stock block..

ss box works very well with a good tuner..i would do full vortech kit and add the 3.12 pulley and exhaust and get a good tune..u will make 400whp and love the car for a cheap price..i had enough fuel on stock injectors and all for the 3.12 pulley

Damn man I want to take a ride in a an FI car sooo bad before diving into it head first. Fastest import car I have even been in was a civic and that was all motor.


Anyone from Philly or NJ feel like taking your boy Phreak for a ride?

Nothing in the world would cause you to put down such low numbers other than either some serious engine problems, or a horrible tune; especially with the pulley you're running. Mine was done on 93 octane, and in the dead of summer.

I'm moving to North Jersey in a month, so if you haven't had a ride in an FI Z by then, I'd be glad to give you a taste to get you excited about doing it to your own car.
