so, i'm guessing...

Vortech kit, used - $3.5k + $1k install
Cams - $1k + 1k install

it'll be at least $7k... those extra $2k really kill me there... so broke... need to stop spending money on my car!!! but i want POWER... dammit...


Ahh man i'm sorry. After much thought, it makes no sense for me to sell it. If and when I do the car will go along with it. Until then i'm going to enjoy it
I just need to figure out how to fix that rear deck creaking and i'm sure i'll enjoy the car more. Funny how a few creaks here and there can make you feel sick about your car.

Igor,
You've already got some kick *** mods on your car. You might want to find what FI kit will work best with the mods you already have. If you are able to get a single turbo or even a used twin turbo, I think you'd be happier with the outcome more so with a vortech/stillen set up.

sukhi, i would love to, but i don't want to pay for a blown motor. it'll be just too much. and the price+install on turbo is too expensive too.

i am begining to think how much longer i will have my car... 1 year? 2 years? 3 years? will i be able to afford something better/faster then?... grrrrrrrrrr.................

well the cams let air in and out better, but the engine is still creating bigger explosions as a result which = more power, which is more stress - but still you're right, it's less stressful than cramming more air into a slower breathing engine

it's for sure safer than a 2.87 pulley. The vortech's intercooler isn't very big and I wouldn't use the 2.87 pulley unless I had a water injection kit

When will you get the idea he DOESN'T WANT THE VORTECH. So get off the vortech kick will ya.

just offering some info man, sorry geez sorry. He said he's considering getting vortech and cams

I don't care what him or anyone buys really - what bearing does that have on me?

it's not that i don't want the vortech. i would prefer stillen if i could find it used locally, with the hood. Sukhi's kit was perfect because even his hood is painted the same color as my car.

but i want something safe, that'll give me power cheaply. i would do Vortech if i could find a cheap kit. i am tired of spending money on my car, with little to show for it. no, don't mention NOS to me. but until i can find a cheap used kit, that's all-inclusive, and in good shape, i won't go FI.

in conclusions...

BOLT-ONS are a WASTE OF MONEY.

it took me over a year and many $$$k to come to this conclusion.

i don't expect to have 450rwhp - not even 400rwhp. i would be just as happy with 375rwhp. very very very happy.
You don't need all of that for a safe Vortech setup ... my car is living proof of that. Stock injectors, stock fuel pump, stock cams, stock Vortech pulley with a plenum spacer and open exhaust. The final step is a good tune and you will be in the same boat I am in with 370'ish rwhp safely for a lot less money than you're thinking.

Sentry; I see you're still representing at full force. Now your points are getting boring. " Who drives w/ a 344 whp vortech these days? " = (meaning) Vortech and Stillen; both out of the box; present peak numbers which aren't too far off from each other; yet Stillen walks the dog when it comes to the mean HP. I don't know what you had in mind when you went w/ a Vortech; but when and if I do go w/ a supercharger; I want to run it straight out of the box w/ no problems. Someone w/ a 350z blew up his motor w/ a Stillen kit that he tried to tweak? ANY kit can make a motor blow up. How come you never mentioned the dozens of Vortech using motors which have seen failure? Like I said before; if Vortech needs the right "tuner" in order to even keep it at safe a/f ratios before daily driving....the Vortech kit is a TUNER kit. Not an off the shelf kit like the Stillen. You are talking about "Torque pressure" or some other absurd notion.....when facts are laid out; Stillen has a warranty available for the motor when run in an off the shelf configuration. How many people have had to cash in on the warranty? One or maybe two? (As far as I know; it is ZERO) If Vortech had a warranty for your motor; they would be out of business. Sentra; or sentry; when it comes to magazine statistics you are like a walking encyclopedia. But when it comes to real world facts; you are blinded by your unhealthy devotion to your tuner camp. Be happy w/ what kit you got (if you are happy w/ it) ; point out the benefits of the kit which you liked; and why you are happy w/ the kit. Do not try to make comparisons and put down other kits in ways which are not only illogical; but show your lack of knowledge when it comes to forced induction.

The stock vortech kit with the stock 3.33 pulley is basically considered "stage 1"

If you'd like to upgrade the injectors and the 3.12 pulley - that's a "stage 2".

If you'd like to then upgrade to a return fuel system and the 2.87 pulley - that's a "stage 3"


that is a pretty weak vortech and pretty strong stillen you're comparing. The vortech has lots of room to grow and the stillen doesn't

I'm not disagreeing with the data and believe it to be 100% correct, it's basically exactly the same data I've stated except you never did give me your 338whp stillen graph otherwise i would have factored that car as well into my % comparison and I couldn't find a vortech that dynoed lower than 350whp. The only stage 3 stillen dyno I could find off hand was a 323whp. I wanted more graphs, but I could drop a pin it was so quiet in here with anyone else who had any dyno charts

who actually drives with a 344whp vortech these days? Back 2 years ago maybe, but that's like a bone stock vortech setup on a bone stock car. Yes it is comparable in the fact that some people just might run that setup, but the vortech has an additional 140+whp available to give you with a full exhaust and pulley change. I've never seen a stillen hit even 380whp.

I was reading about one vender who has tried to get more than 360whp on the stillen with headers, test pipes, exhaust etc with a stage 4 and they kept running into a wall trying to do it. No matter what they did, it didn't seem to ever go any higher and sometimes even lost power with some of the changes they did. Actually Stillen themselves were trying to get a lot of power out of their kit with other mods and ended up blowing up someone's engine with the stage 4. It was on my350z.com. I don't remember which vender or who's cars it was in either case, but it's a fairly recent thread in the last 6 months

These days people don't often use the stock 3.33 vortech pulley since the 3.12 has proven to be so reliable and give an increase in power/tq across the board

Just saying I rarely see a vortech car below 360whp these days


BTW, if you have a 344whp vortech and a 338whp stillen - guess which one of those cars is actually harder on the engine? It's the stillen because daily driving you're forcing more air into the car even at low rpms. The vortech doesn't get much psi in daily driving rpms. It's not until you floor it.

People say torque breaks parts, well the stillen is making full torque at low rpms. The engine speed isn't very high, but the tq pressure is decently up there. Most people that have blown up engines with vortechs have done so because it wasn't tuned right and/or they were trying to make a lot more power with other mods and they skimped on something

right. peak power is the same. Stillen wins in the stock kit catagory against the vortech at least against a "stage 1 vortech" because that's the only vortech setup that will make a low 344whp.

If all you're shooting for is 344whp, I'd get the stillen kit because of all the extra low rpm power. It's just a better choice for a safer lower whp setup

that's a false blanket statement that isn't true in all situations. As far as a stock kit out of the box the stillen is better. Can we agree on this? Can you see I'm not saying otherwise? However, the stillen being designed as it is - Roots/twin screw design, it isn't as efficient as a centrifucal when making bigger numbers. So when you take a stillen kit and try to get a LOT more power out of it, it doesn't go over very well. The Vortech kit though does put up some great numbers. We all know this, we've seen 450+whp vortechs that have equal or more tq at 2500 rpms than a 330whp stillen. If you had a 450whp stillen - yeah it'd eat the vortech's lunch, but you're NOT seeing anyone get anything near that high on a stillen kit.

I'm making 450+whp on my vortech setup and still have room for improving up to 500whp if I wanted to push the engine. My mods list speaks for itself. My car is making almost 300 tq at 2500 rpms (dynojet number) That's a bit more than a a lot of stillen kits. And I have 3.9 gears. Up high I'm getting 360-365 tq and it stays there nice and flat pretty much to redline. It doesn't drop as much as the stillen.

Stillen kits have not blown up many motors cause they're extremely conservative as far as stress on the engine. The point about the stillen kit blowing up the engine was that it was pushed hard. Yes if you push any kit, you can blow up the engine. HOWEVER the stillen stage 4 car that it happened to was only doing like 368whp or something - impressive #'s for a stillen, but by design the stillen starts running into diminishing returns when it gets pushed harder. Twin screw designs can't handle increased boost as well as turbos or centrifugals and so the gains start not being as high once you get to that point.

The full vortech kit comes with the SS box with a map already preprogrammed to be pretty rich and conservative. But yes you can buy the tuner version of the kit if you don't want their lower end fuel system and SS box

torque pressure? where did I use that term?

and that is pretty cool isn't it? Actually they just give you a warrenty on the block - I'm assuming a long block, cause only offering a short block would be seriously lame. Either way they don't cover labor - which is probably a $1500-2000 expense to disconnect all the accessories and wiring, pull the engine and put it all back in - and if a dealer is doing the work, it could be even more.

it probably wouldn't be many, but your guess is still just a guess. The stillen is still FI, and if you get a lame driver who doesn't keep up with maintenance or buy gauges to catch a problem before it becomes serious, I wouldn't doubt the engine could be hurt because of driver negligence

I know it's a shock, but most FI companies don't offer engine (parts) warrenties

what do you define as real world? I mean, my car is making 520-530 crank hp AND more power and torque down low than most stillen kits are producing. This is my real world car that I drive.

Sentry, here we go again! How can you say its false when we have all the technical data proving otherwise? Please show your technical data that you have that proves otherwise. Stillen makes the most MEAN HP/TQ over Vortech or ATI period out of the box (all 3).

Funny how you say you can't make a lot of power out of a Roots type blower, but the Lightnigns and Cobras make a ton of power with just a pulley change. So YOU can't say it not efficient enough to do that. It doesn't make the PEAK power the Vortech or ATI does but it will definitely give them both a run.

And the rest of what you said, is plain ignorant. You already proved you don't have a clue about FI kits. I am even sure you didn't install yours yourself.

OUT OF THE BOX THE STILLEN IS BETTER THAN AN OUT OF THE BOX VORTECH!!!!

I swear people don't read these days

now if it's so easy to make big power with the stillen WHERE ARE THEY? WHERE ARE THE 400+whp stillen G/Z's?


If you are into modding and want to make MORE power than the stock stillen or vortech kit, the vortech will give you better results and actually give you more MEAN hp than the BEST stillen G/Z setup

I already gave you two sets of data. One with averaging the area under the curves, and another averaging 500 rpm increments

Sentry and G35 TX are both from Texas, why not you two meet up and see who is faster.

Man this is getting old, I mean if there was anyone in N.Cal with a stage 4 who wanted to race, then my lowly stage 2 Vortech would be up to the challenge.
