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

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.

Yeah, I'm going Stillen because of stupid CARB. Can't risk getting pulled over and having to worry about cops in CALI plus SMOG. Can't say what i may or maynot do to the kit though. Why can't GTM release a CARB kit yet.

Unfortunately, making changes to the kit means it's no longer CARB certified. Granted, they wouldn't really ever know, but by the letter of the law the kit is CARB certified as-is, not with any other tune, pullies, etc.

Most people who buy CARB kits are doing so not because they are completely law abiding citizens, it is because they don't want to get hassled. Call it the "leave me alone and let me have a little fun" tax.

The letter of the law says the speed limit is the speed limit and almost everyone crosses it everyday without a hit to their morals. That is how I feel about changing the pulley size on a CARB supercharger kit.

Absolutely. There's really no way for them to know its not running the original pullies, or that its been custom tuned.

I guess then I never see that speed limit sign cuz I'm flying past it while the stillen guys think there a BAMF for going few miles over?? If ur gonna risk the chance of getting caught you might as well for broke. Reminds me of a funny story I read awhile back.

Spoken like a true South Floridian. Woe betide you if FL ever decides to cash in and jump on the vehicle inspection bandwagon!

I dread the day that happens here

im sure making fake CARB stickers is a federal offense or something crazy like that, but whats stopping people from doing that very thing? can the cop look up the CARB info in his car? and would he even know wth hes looking at?

It's definitely a state offense, I think the police can actually query a database of CARB certs.

I guess I'll actually answer OP's question.. 2+ years and ~15k miles on GTM Stg1 SC kit. 0 issues.

A cop could tell you your life story after 3 minutes on his laptop.

Great banter on the site but THANK YOU for answering my question. All this on a stock motor and transmission?

I would say yes he is, take a look at the finished builds thread. This is probably 15-20% of the actual finished boosted builds we know of. Most are still stock block & transmission.

http://www.the370z.com/forced-induct...ed-builds.html

I don't know if you saw my post but, going on 40k miles boosted (60k total), DD with some twisty road runs in Texas now & again.

I hate this got derailed too, cuz I'm looking to go FI in next few months...and while none of the actual models here are what I'm looking for (TT), it's still a solid idea of what to expect down the road.

I wish there had been less "this vs that" and more "this is my experience".

If you are worried about violating emissions laws, you are a pussy.

I have a little over 20k miles in ~23 months on a daily driven GTM Stage 1 SC (turnkey) kit with the GTM oil cooler supplement w/remote thermostatic adapter. I am at 419WHP/350WTQ@8PSI

Additions since the original install

• GReddy Turbo Oil Pan
• Fender Lining Vent and SPAL 7.5” Fan for additional oil cooling (fan seems to be the best cooling addition so far)
• Custom UpRev Tune (just to eek out a little more go-go juice)

** I had the ZSpeed aluminum under tray but sold it because it did not fit well with parts of the SC kit. I have a NISMO so this might not be the case for other FI kits or the base Z.
** I had the Motordyne ART pipes for a while, but could not get them to seal properly. I went back to the stock cats.

Maintenance

• Went through the OEM Yokohama Advan’s in less than 10k
• Eneos oil change every 3k
• Differential change every 7.5k
• Manual fluid change every 7.5k
• Air filter service every 10k
• In August, I will be 2 years on the kit and will change the Rotrex fluid and probably the drive belt

Issues - These are problems to some and not so much problems to others. It is all relative.

• Depending on your technique, tire wear might be considered an issue :eek:
• Several oil leaks with the hoses that deliver oil on the oil filter relocation kit that was resolved with new hoses and AN fittings
• Had a power steering hose issue that resulted in a complete fluid dump, requiring a wrecker. This was also resolved with a new hose and fittings. Look through the GTM install instructions for more details about the power steering hose modifications during the install of the kit.
• I tracked down a knock/rattle in the front end that I need to fix. The power steering cooler and bracket are loose, so the power steering cooler is knocking between the radiator and the intercooler. Again, look through the GTM install instructions for details on modifications made to the power steering cooler and mount.
• Even after a custom tune, I still sometimes have a slight idle issue that seems to be normal. I made a thread about it last year and the conclusion was it was a normal occurrence.
• The plastic NISMO undertray does not fit well with part of the intercooling piping and has a tendency to come loose at points especially at speeds well over the triple digits. I have replaced and lost several pop clips.

As I have said on the forum before, I do not launch the car. It is kind of silly and a waste of some expensive rubber. Yes, I gained torque and power down low, but to be honest to car is not magically super fast off the line with the SC. But from a roll, that is a very different story.

However, I have done some hard driving in 2nd, 3rd, and 4th gear. The car gets driven but not abused. It has been a lot of fun which was my goal. I am still on the stock clutch and CSC if that tells you anything. But I have funds set aside for when they strand me on the side of the road. That is not an if, it is a when. I have not tracked the car yet but it does get driven daily.

For all intents and purposes including the cash I dropped from the beginning of this project, I am pleased with the GTM kit and have no real complaints.

[EDIT]
Also, I don't fault my issues with GTM or the shop that installed my kit. That is the price you pay when you mod a brand new car. The OP and some others asked for real world issues and I am just being honest.

I have the stillen kit and don't regret it I love it and it runs good. Makes 430whp and 315 trq. the stillen injectors suck and the stillen tune sucks also. I had mine tuned at uprev in Austin tx with 725 injectors. she runs great no problems. I have about 20k miles on this kit now.

I have the Stillen kit...but only 2-3 days in lol. With the upgraded pulley (10psi), Turbosmart BPV, Berk HFCs, GReddy Ti-C exhaust, OEM MAFs, and Motion Lab UpRev tune I got 422 hp / 318 tq @ 6500 rpm. My OEM MAFs were maxed out limiting my rpms.

Once I upgrade my MAFs and retune, everything will be great, but so far I have no complaints. I'm in hot South Carolina now and have been doing some hard highway driving; temps haven't gone above 200 on the factory Oil Temp guage. I've got a Stillen Gold Series oil cooler, Mishimoto radiator and thermostat.

Driveability has been awesome and the power increase feels great. I love the whine of the supercharger. People tend to have a "WTF"/perplexed look on their faces when I drive by....they either think something is broken or they know whats up.

I've got a 1500 mile road trip to TX tomorrow, so we'll see how it holds up while driving across 5 different states.

CG's on the new kit :tiphat:

Yes. only thing changed out was clutch. Mostly because i got a deal on it.

This thread died out.

Wondering if it is possible to continue with a Stillen + A2A upgrade vs a Gamma Stage 2 kit?

Why not start a new thread?

Im a bit scared too...

I have a little over 3 years on my Gamma (GTM) Stage 2 kit without any issues thus far at over 500 to the tire. I'm thinking about pulling the kit here within the next couple months and changing my setup and selling it. The Rotrex charger has been really rock solid. This kit is great for a 500-540whp range (depending on the dyno). I'm looking to build the motor and shoot for more would be the only reason for sale.
