And on your registration it says 370z too right.

And with all that kit and meth injection all you got was 140hp and 70tq over stock

When my GTM got me 236hp and 133tq over stock (@ the wheels) with no meth,so I guess the Stillen is a good buy.

Yep. Totally different engine and kit. I'm wrong. Sorry for posting in 370Z threads. I'm out.

HR motors aren't drastically different, Pro's gains would be similar if they were on a VHR motor. It may be argued the HR motors can be tuned better because of better control of the cams.

On that note, it took a heck of a lot to make 140whp/70lbft over bolt on mods.
Meth on a GTM stage II kit is a 543whp and 405lbft/tq. (Staples)
Baer383 is using GTM's 1.5 kit and no meth.

GTM's stage 1 SC kit pushed 460whp which is similar to a Full bolt on Stillen kit on high octane.

Long term reliability really comes down to how you take care of your car. If you get a solid install, tune and proper supporting mods it is all on the owner. Both kits are well made and will last for years, but it is the owner which will determine reliability.

-Doing all maintenance in time, oil changes (both motor & SC unit), filter changes, etc.
-Keeping an eye on the system in extreme use, super hot days, tracking abuse, etc.

I have over 40k miles on my GTM Stage 1 SC kit and still going strong. Going to be doing some maintenance soon, oil change for the unit & filter changes. Only issue I have had is I blew a belt around 25k miles into my install, they are suppose to last 40-50k, but things happen. Towed it back & put a new one in, no problems.

Also, determine what your goal is for going boost. Do you just want more power? What are your plans, DD, track, etc. Make sure you over budget and over plan for everything. If they say 3-4 days for something estimate 5-6 as problems can occur.

Tuner means it doesn't come with injectors, fuel pump or tuning license/maps.

You can get it pretty cheap. You have to spend for all that stuff though, so he's pretty much lying out his *** if he is trying to say it cost him $5300 out the door.

I'd venture a guess and say he's around $8000 spent total, if nothing had to be done and re-done multiple times (racking up lots of labor cost).

Who pays over 5k for a 140hp and 70tq bump????????? Just further justifies the argument against going stillen. For that kind of money your better going of with a proven kit that makes real power.

Pro4Jackster

You are right. I already had fuel pump, injectors, and uprev sitting in the garage. They can be found used very cheap, because people constantly upgrade. "Tuner kit" goes for $5200, just as I stated. No need to call me a liar. I never said out the door. And I'm not trying to be "pro Stillen", because their salesmen are a bunch of idiots. I wanted what I wanted ( a vortech blower), and I'm happy with my purchase. I didn't come here to argue. I saw a question I thought I could answer, so I made a huge mistake and commented in a GTM vs. Stillen thread. Something I hope to never do again. There is no perfect kit for everyone's goals. Thats why there are options. If your goal is max power at every Rpm, go TT. If your goal is to have a DD that your wife can drive on wet pavement, but still have good power above 4500 RPMs, get a Stillen. That is my opinion. That is not fact. Now please continue with the endless debate.

I have to agree if I had to do it over I would not have gone with the Stillen kit
That kit is a one shot kit the way it's make limits it's power and 99% of every one that goes for boost always want a little more

I made 430rwhp ok power but not for the money i paid
If you go forced induction go turbo or go home....

No offense to the supercharged guys just my 2cents

That's a pretty ignorant thing to say, especially coming from someone with a SC kit. They drive entirely different. Just because a turbo makes more power does not make it the only way to go. My kit can be upgraded to 800hp... It's a SC kit. I won't be coming close to that, but I'm not limited. When you have to say "no offense", that's offending. You told us we were wrong for going SC, you didn't even explain why. Enlighten me why going SC shouldn't be an option. I'll reply with a truck load why it is.

Your argument makes no sense. If max power per dollar was the only goal, we would all be driving Mustangs with the new 5.0L. There are many other variables that affect our FI decisions. In the end, it is all what makes you happy. If the buyer is not happy with his purchase, then it was a mistake. You are obviously very happy with your decision. Good on you. New Mustang guys who spent thousands less think we are all retards, but who gives a **** what their opinion is...or mine and yours for that matter.

Hold on cowboy don't go for your gun just yet lol
I am talking about Stillen kit for the most part but if your happy with what you got great but A turbo car will win any day of the week pound for pound of boost
And easy to make power
Now drivability ok supercharger

And yes I admitt to not doing my home work going from a mustang to a 370z I looked at Stillen and saw a vortech blower and was like ya I had that on my mustang makes great power. That's how I ended up with a Stillen that being removed off the car right now for a turbo

This I can agree with
SC's are easy to make power as well, but not like turbo's. No "easy button" The Vortech unit isn't bad, it's really because Stillen built the kit to a price point, and not the other way around. Losing the strut tower brace is a no go for me too. That's just too bad arse to come on a factory car and get removed lol.

I'm not talking about mustangs. I'm talking about the VQ platform.
The amount spent on such little gain doesn't justify it for ME. If I'm gonna spend that kind of money I wanna feel the power increase.
For the stillen price tag you might as well stay NA. Yea there 2 different kinds of power but in the end money is money and like everything else I wanna get my money's worth

Pro4Jackster

It's still all relative. You accomplished your goal. I accomplished mine. But it's silly to compare the Stillen kit to N/A. I hope nobody actually believes that.

There is no denying the facts. GTM S/C makes more power. Stillen makes less power. But power is not the only thing to consider. And reliability, it's a draw, because both kits seem to use quality parts. The key to reliability has already been covered a few posts back.
