Hey guys I'm getting my G35 Coupe in about 2 weeks. My dad is getting me the car and my mom said she will buy me a SC as a B-day present. I don't want a turbo because for smog checks and I don't know which one to get Stillen or Vortech. Can you guys give me some info on them reliability warranty and power and pricing if you can any information will help me a lot thanx.

 

Vortech...

You might want to post this in the Forced Induction sub-forum though.

.

 

go with the vortech. you need a new hood for the stillen. check out the forced induction forum and browse for a bit. also check out my350z.com for a ton of boost info.

 

Those are some unbelievable gifts man, seriously like over $40,000 worth. (if G is new) Also, how do you feel about your stock hood? I say Vortech, biased because of my past history on my ol' Trans Am.

 

My dream is Vortech and full of jealousy, cuz you're mommy and daddy boy. I have to work my a$$ off to pay bills and living.

 

It depends on what kind of power you are looking for. The power from Stillen comes on immediatley and stays strong through the lower and mid rpm's. The Vortech is more like a turbo, giving you that rush of power in the higher rpm's. I suggest trying to catch a ride in both before deciding.

 

The Vortech is not like a turbo kit, the Vortech comes on at around 3500rpm and keeps on going and going but there is a lag point which you can keep to minimum if you keep it in a lower gear. A turbo kit depending on what size turbo you go with i.e. APS TT or Greddy TT do not have no where near the lag the Vortech does, I have almost 380rhwp by 2500rpm, the small turbos are made to be the most optimum for all round power.

 

^Does a single turbo behave closer to Vortech or a TT?

 

no you do not have 380rwhp at 2500, you probably mean tq.


otherwise 380whp at 2500 rpms is exactly 798 tq and well you don't have almost 800 tq at 2500 rpms, that'd hurt even a built engine


furthermore, what you're describing as "lag" is actually called boost response. The vortech has zero lag as in the true meaning of the word lag - hit the throttle, and the engine instantly activates the blower. Doing that on a turbo, depending on rpm, will have a split second delay as the exhaust gases build up heat to get the turbo going, then shortly after you get lots of boost response

no one cares about 3500 rpms and below anyway when you're racing. If you change your final drive, you're higher in the powerband with the vortech and with greater gear tq anyway. It still won't beat a turbo in sheer power though, but it closes the gap a little.

 

TT

the vortech is obviously a compromise. The vortech's blower not only makes high boost up high, but it's blower is more efficient up high vs down low. A normal turbo kit has the turbo the most efficient in the midrange mostly due to its size so it spools up fast. A kit like the SFR TT kit with really big turbos that spool up later so there's no boost, no boost, still no boost, then a crapload of boost - they're very efficient at high rpms because they're bigger turbos.

The vortech is a compromise in that it does build up some boost down low - even earlier than a lot of turbo kits, and builds it up to peak boost at redline. It has some issues with parasitic losses though so it'll never pump out as much power as a TT will, but it pretty much equals or beats a ST setup in the high end, but not the mid range

 

^Thanks for the info (Not sure if this helps minoz35 with his decision, but whatever).

 

Sorry sentry I meant trq. but when it comes to response there is a difference between the vortech and the TT, I had a vortech and there is def. a delay when hitting the gas, call it lag or response but it is there. Also I know for sure that my car is faster than it was when it was SC.
I know you are a fan of the kit but so was I and I have moved on since then.

This does not help the OP so I am not going to deviate from the initial question.

 

yeah a turbo will kick in much sooner with lots of boost than the vortech will. I'm not a fan of the stock vortech kit. I really think the kit is lame unless you upgrade the pulley a size or two and change your final drive - unless you're making like over 500whp with it and would rather have traction than shorter gears

 

Completely agree with you on that, but hey that is the best thing about the Vortech...it is upgradeble

Mine goes to GT motorsports this weekend for a built tranny and new numbers we shall see about that 500hp mark

To the OP go with a Vortech...lol

 

If emissions are an issue, then TT or ST isn't even an option. Go with the Vortech for upgradeability and CARB approved.
