I've done tons of research, read numerous threads on here and on my350z and spoken with several shops and I am no closer to deciding on what I want to do. Both the Vortech SC kit and the JWT TT kit have its pros and cons and I have gone through them all. One day I like the Vortech and the next I like the JWT TT. Damn, I didn't think it would be this tough of a decision. So what do you guys (and any gals that have an opinion) think? If you had a choice between these two kits, which would you pick??

 

honestly.. jwt because they know the g/z inside and out, as does vortech but i would feel better having vrt do my car, and they are a little more reputable imo...

 

Turbo!!!
Are they both carb legal???

 

u going to build if u go jwt though?

 

there is no legal aftermarket turbo for this car

 

When they gonna make them (turbo)carb legal... I've been hearing things for over 2 years now...

 

I had a long talk with a Rob at Z garage and if I were to make an educated choice at going FI, I would go Vortech. Reason being, the twin turbo set up requires a lot more maintenance as well as has a strong risk of something to go wrong.

One thing you probably take for granted right now about your car is the reliability. You can hit the pedal, smash down the freeway, and know damn well that all is working right for the most part. With a twin turbo set up, you have to make sure you have enough oil when you go out, make sure the right octane is running, and worry that eventually, even if you do all these things, that huge boost that is coming might just bend or snap something.

Now on the other hand, with a Vortech, you can gun it a bit more, with a bit less stress. You may not make as much power, but you will certainly not be hitting your engine with sudden masses of boost. Don't get me wrong, an SC set up will wear on your engine too, but you will be happy with the results you get no matter what.

Other thing he told me was that an older white guy had just dropped about $15-20K in engine parts for a TT set up and was driving around and got popped by the cops. The cop knew what he was doing and sent him to the referee. Now he has to spend $3K to get this car back to stock. With a carb sticker, you can have fun, and po po can't take it away.

I would rather have reliability and more peace of mind, than crazy power and risk. (Better safe than sorry).

But that's just me. You asked...

 

Not at first bro. I've spoken to Scott @ Relentless about this several times now and he has assured me that it is not necessary to build your block if you are gonna stay at 400whp and below. If I ever decide I want more power, I could always build the block and turn up the boost.

 

Yes I did ask and I appreciate your opinion. You basically just summed up my dilemna. Everthing you just said is everything that I keep going over and over in my head. The Vortech setup is also a couple of grand cheaper too and I know that I would be more than happy with it. But going TT is something that I have wanted to do for the longest time. Also, your story about the older white guy is a big deal to me too. Believe me, being CARB exempt is a huge reason why I really like the Vortech kit and brings the JWT kit down a couple of notches. If I hade to pay a couple grand to install it and then a couple of grand to remove it because I got busted, I would not be a happy camper. I'm going to GT Motorsports this weekend to talk to the fellas there to get their insight. I am still pretty much 50/50 at this point. :/

 

Go Vortech. Ill tell you why:

-You live in California. Goodluck with a turbo
-Although a turbo only "seems" to be a bit more expensive, with a turbo, it is much more necessary to do internal engine work to stay on the safe side. FI isnt "safe" to begin with. Engine work such as rods, pistons, heads, etc can cost you more than the actual FI setup itself.

I would still recommend upgrading the internals on any FI application, but you are on a much safer side with a vortech if you have it tuned properly.

Not only that, but Vortech seems to be much more reliable than any Turbo setup.

.

 

That's misleading, although he's right.

With a Turbo, you might be making 400 whp & 400 wtq; while with a Vortech, if you push 400whp you'll probably be making 330 wtq.

With the situation I just stated, the turbo is much more likely to cause something to break.

But like I'ved said, FI itself isnt "safe"

.

.

 

Very true. Any form of FI is not safe. Vortechs can blow engines just as easily as turbos. It's like trying to pick the lesser of 2 evils. lol!! Believe me, I have contemplated everything you have said bro. The guys over at my350z are very knowledgable and they have given me tons of info to go over. Who knew going FI was so much work. :/

 

Hehe I am about 4 years away from FI; there's a reason why I started my research a year ago

And yes, I still have alot of stuff to learn!

I'm pretty sure you already spoke to him; Sentry himself has a pretty damn good Vortech Setup. He's both here and in the Z forum.

All im looking for is 450whp on a dynojet and im set . A centrifugal SC, or any SC, will never give you the torque of a ST or TT, but hey, aslong as I hit 450 whp on the Vortech, ill be satisfied. That should give me around 380 wtq which is good enough for me. But by then, I should have done work on the internals.

I think I will lay around 400 whp until I have enough money to touch the engine.

Funny, I am nowhere near going FI as of today

.

 

^^^Baahahahaa!! Patience bro. You will be there before you know it.

 

for me, its allll about the carb legal.. there are countless times where i'm driving at night with the vortech with a cop pacing me.. and not have to worry. I can't imagine how I would feel with a turbo in that same situation.. especially when they already see the gauges! IMO it's not worth the hassle of possibly getting busted for that. However, if you are a risk taker, then go JWT for suuuuure
