iam going for FI soon and my car 2004 AT so which is the best one between both of them(for AT)out of box?

my mods are
AAM spacer
topspeed header-je hot
UR pelluy
test pipes
dual exhat

if i go for vortech i have to change only UR but for turbo i hvae to remove everything in the car.one thing that we have unichip tuner near to us

which one the best out of box?

and can i use unichip with vortech insted of SSbox?



i drive the car of my firend same my car with vortech he got boral headers and dual system and he fix it out of box (with SSbox)without tune so the car run smooth.thatswhy i will go with FI

 

The Vortech is awsome and you will be plenty pleased with it and is very reliable. I say it can be a cheaper alternative but if your planning on dropping some money and want to really get boosting go with a turbo kit. If you do the turbo get your internals done and turn up the boost!

 

the thing is that with the mods i have can i fix vortch out of the box without tune?iam only looking for 330rwhp and iam not looking to go above 330rwhp.other thing can i use unichip insted of ssbox?

 

It is going to be rich out of the box so you will need a tune. Why not at least shoot for the 380 whp range that the kit can safely deliver?

 

but the thing we dont have shop to tune the SSbox which comes with vortech,what we have is unichip




is there will be prob to fix the kit out of box without tune?

 

You do not need a tune for the kit to run fine (although rich AFR as noted above)

I am based in the United Kingdom and experienced a problem with the SS Box having a corrupt map. I got the base map for the SS e-mailed to me by Matt@CPRace and downloaded to SS and sorted the problem.

The point is, any issues you might encounter (and you'll probably have none) will almost certainly have been seen before and can be fixed by posting and then following advice from this forum.

For the record, my car dynoed at 353WHp on DynaPack with no tuning whatsoever.

 

I would get the turbonetics kit. The difference in torque will be amazing and worth choosing the turbo kit over the SC. Since they 'tune' via a reflash, you can kind of set it and forget in some regards.

 

if you have a unichip tuner nearby, why not go with aps?

 

Does anyone actually have a unichip tuner nearby?

I love my aps kit and all, but there should be more flexibility in getting it tuned.

Between the two options above, I still say the turbonetics is the obvious choice. However, I do agree that if you have the ability to get it tuned I would choose APS over both.

 

he said he does in his first post.

 

There was a bit of sarcasm in that comment since my "local unichip tuner" is about 450 miles away. A mere 1:18 minute plane ride and 30 minute taxi ride from me.

My plane leaves tomorrow at 7:00 AM and I should have a fun ride home with my NEW AND IMPROVED APS TT 350Z

 

I have an 5AT Z and I am pretty sold on the turbonetics b/c the 5AT version was the only kit that was designed and tested for the automatic version of the Z. If you go with vortech you will have to get a reflash done by TS to have the rev limit raised.

Assuming I ever actually go FI... (big assumption) I would get the Tnetics kit unless someone else makes a kit designed and tested around the auto Z.

 

Just curious, why would you have to do this?

 

Because of the added power, the auto tranny isn't always able to shift right before redline, and sometimes hits it. However, you would have to do this for any FI u go on an Auto Z, except on Tnetics I would assume they would include a raised limiter in the reflash for the auto kit.

 

In addition to the advice given above, mine would be to compare the driveability of both systems and match them to your driving style. You've already driven your friends SC'd Z and know how that feels. If anyone's got a turbo'd Z and would be willing to let you take it for a spin, or at least give you ride, then I think in the end when you make your decision you'll be happy. Alleviates that "what-if" feeling if you chose system over the other.. I've driven SC'd cars (not Z's yet) and owned a TT Supra and they are somewhat a world apart as far as driveability goes.

 

I had the Vortech installed on my car for about 6mo. It was nice but I had problems with the BOV making noise and also the blower had to sent in to Vortech to be rebuilt. It made 376 RWHP on my bone stock 350z, but it was not as fast as I wanted. You will always want more.

When I drove a turbo charged 350z with about 20 less RWHP it felt so much faster. The torque is what I was feeling. That is why I sold it, and now on NOV. 17th I will be turbocharged. Good Luck.

 

i'm going with the vortech kit. This topic comes up every week (SC vs ST or TT) My car has plenty enough tq or ***** (f you will) because of my 3.9 final drive and light clutch. Not as much as a turbo, but I do have traction at least. The vortech will help me maintain that traction and with the KJR pulley and ATS clutch, it'll zip into boost in no time - where more tq is. I like the idea of 4k and up having the car get really mean vs the turbo having the most tq at 4k then dramatically dropping off. Also the TN kit is decently linear in it's power, but still has a bit of a curvy slope to the hp curve.

I know a SC puts more stress on the pullies or bearings or whatever, but a turbo will put massive amounts of stress on the rods, and since max tq is around 4k, you'll always be putting max stress on those rods whenever you go WOT in just normal daily traffic. With the vortech, you can go WOT at 4k and it'll for sure be stronger than NA at 4k, but it'll also ease you into the tq instead of slamming it into the engine. It's more controllable. Some might say you just need to step up and get some ubur elite turbo driving skills, but whatever. I value cars that are easy to control that don't need drag radials and some special driving tricks to drive fast - IMO


The turbo kits have so much tq that they lose traction. It won't be hard to fishtail off the road or lose control if you don't set the car up well for balance. Even then people are driving around on drag radials on the street in order to get decent traction.

Maintaining traction and having the car be predictable in how the power is delivered is top priority to me.

 

what he said but you don't really have to do it you can always use the manual mode and shift yourself before it bounces off the rev limiter but the flash would help you out and allow you to go WOT in "drive" and function correctly. The Tnetics flash for the 5at will raise your rev limit.

 

I would say go with the Turbonetics kit. The only thing you would actually HAVE to remove would be the aftermarket headers. The kit also includes a rev limiter bump to help with shifting.

 

I think this is very good advise. I doubt though anyone with a tubo has a "what-if" feeling towards a SC. On the other hand, there are at least a few, if not many SC owners that had, are having, or will have second thoughts about a SC once they ride/drive in a turbo'd car

CASE IN POINT:

I think this this the best answer to anyone asking about SC vs Turbos. Don't look at the numbers, they don't give you the real world feel of the car.
Turbo > SC ****even with the turbo at less HP****
