I'm gonna go ahead and ask which is better, a vortech supercharger or a single turbo kit. Both are around the same price, and both make about the same power. Are there any additional benefits to installing one over the other?

Also, I'm not sure about which ST kit I like best, and ssr-engineering is coming out with their own in about 2 months. Man this is like when all the twins came out. So many options.

 

My understanding is that sc's can make decent hp but seriously lack in the torque aspect. For instance, I have seen with the Vortech kit, members on this forum, with 375+ whp, but only 310-315 wtq. Now with that said, my kit the TN single turbo, I make a little over 372 whp, but I have 366 wtq. IMHO, I would go with the single turbo, mainly because I have had sc's on other cars that I have owned, and I loved them on V8's, but the torque will not be there on our VQ engines. I would go with either of the single turbos you choose. I prefer the TN kit, but I really like the APS kit as well.

Also the Turbonetics kit is very easy to install, and I am sure many of the members of this forum would agree, in terms of ease of installation, the SC and ST are probably about the same? I have no experience with the Vortech on the Z, though.

 

Very true what was said above the kits are very capable of making the same hp. but the Turbonetics makes more Tq. One plus to the Vortech is that they come with the split second boxes which allow you to do custom tuning if interested. The Vortech is a slightly simpler install but not to much more difficult then the Turbonetics kit.

 

depends on what you like and want.................ST will be easier to get more power out of later................

 

Despite the TN's claim about 8 hour install, you will not find a tuner who will install one for you for 8 hour time price. The labor difference is about 1 grand.
SC's are more linear, the "lower torque" will not be an issue, for all its worth the car will be very forgiving in terms of drivability, as opposed to a turbo. A Vortech'd car feels like it's the same under the hood, but the car just lost about a 1000 pounds.
You are not winning anything in terms of reliability, both kits have their own issues.
SC's are very capable of making very good power, but the car will scream like a banshee on crack, so if sound is an issue, you may want to consider a turbo....

 

priceless! sc scream will scream like a banshee on crack hahaha

 

there isn't really a comparasion .... ST puts out alot more torque and power compared to most SC.... also ST are going to be alot faster because boost is greater with ST than SC... if you want to be safe.. SC if you want to be fast and powerful.. ST

 

Trying to decide what to do is driving me nuts.

 

To add to what I said earlier, I have owned a supercharged V8 4runner in the past(I know not a Z), but in my opinion, the st or turbo in general is so much more fun. A supercharged car just feels faster from start to finish, but a turbo, a turbo, man that BOV coupled with the onset of boost once the turbo has spooled, there simply isn't a better or more enjoyable driving experience.

 

See if you can find both a SC and a ST in your area . Get a ride in both and make up your mind that way

 

agreed taking a ride would be your best bet you can make power with both people seem to think that you are stuck at the 400hp mark with the supercharger which is not true. Andy is making 450hp with the stock supercharger vortech does make upgrades for these kits so there are bigger superchargers you can go to if more power is needed

 

+1 on the st, it's a lot more fun and sounds amazing.

 

Im running the T-trim blower now..was stuck at 13.5 psi , built motor and 9 to1 comp. pistons I made 400whp on a Mustnag dyno ..DynoJet # should be quite a bit more..450 to 470 range . After that , I believe you need to upgrade the IC and pipes from the IC to the throttle body . Im working on that right now . I will find out if I can make more PSI , but for sure be able to flow more air for more power . BTW , I have an AT5 and have a trq. converter and just installed the SGP valve body

 

sounds like a good deal will be interesting to see how things go

 

Welcome to the "Undecided Club".
I am begining to realise that "perfect" FI kit does not exist. For each kit there is a ton of reasons to go with it and a ton of reasons not to go with it. All of reasons are different, so you will have to eventually sacrifice something...

Not that it hasn't been said a million times, but Road and Track Speed had a comparison test of two twin turbo and two superchargers, its a good read. The vortech does really well in the test (comes out fastest in the 1/4 mile and 0-60, although the 1/4 mile trap speed was lower than the greddy tt, so it was catching up quickly).

Another factor worth mentioning is the removal of cats with a ST setup. It may not be a big deal to many people, but its a show stopper for me. I would consider the Turbonetics kit with the high flow cats, but there is no data with performance numbers out on it yet (mia is waiting for the results).

Im leaning towards Vortech right now simply because of the reliability (look at the number of kits installed vs. blown engines), the cat issue, and the fact that the best Vortech tuner in the US only 2 hours away from me.

 

I would be nice to see a z hit high Hp with a s/c like the Rustangs do...but then again they have +2cyl on us so that might not happen soon............even if some one were to hit 500whp with a s/c that would rock................but even if that happens ill still have to say ST

 

If I dont do it...Gsport mag has a car at Vortech right now doing a custom T-trim set up that will for sure
