It looks like I will be going SC in April/May. I need a daily driver as it is 55 miles to work (ONE WAY) and I will log 15K miles per year on the system. Has anyone ran ther SC system this much? Should I go Stage 1 or 2? I do not want TT.
Most of the road is 65 MPH open highway and a small 15 miles in town. I need inputs as to the reliability of the GMT systems. If the car can be made stage 2 and a dailly driver; that is what I would like, around 500 RWHP

i was looking at the stage 1 system but you only get like 400rwhp, and i thought if i am spending the money might as well get the stage 2 and get like 480rwhp. i am planning on doing this as my DD but i only live like 5 miles from my work so i wont be running it that much. i was tossing up between the stillen on and the GTM and the GTM one just seemed like less problems and more reliable, also the people from GTM as just awesome. and a side note you dont have to change/alter that much of the car to fit the stage 2, where the stage 1 and the stillen kit you have to cut and remove some things.

500whp is a lot of power. It's more than I would want to run in a 370Z for daily driving just from a reliability standpoint. I'd be very comfortable, however, pushing around 400whp. For the weight of the car it's a really good balance and isn't "omg too damn fast for the street" and is going to be easier on the car which is a good thing since you are going to be driving it every day.
I would drop theDreamer a PM with some questions... I think he was one of the first to have the GTM Stage 1 done, and he's right at around 400whp.

I'd go with stage 2. That way if you need the power it's there. Reliability is in your foot and how much you get into it. It's not like your going to be boosting every moment. When your FI DD shouldn't be any different from stock.

Exactly. How often do you see yourself redlining the car right now? Surely it can't be off every stop light. I know I only get into my car once or twice a week.

I just don't like pushing power on a DD. Weekend car I'd be all for 500whp, but for the daily I want something more conservative. Yes you can take it easy with the stage 2 build, but the stage 1 will still be easier on the car.
My job is about managing risk (investments) so I guess that's just how I am wired to think.

Again, has anyone put 15K miles on a SC car last year? Did you have any problems? Stage 1 or 2?
If I want go big or say home, I'll go port nitrous til the motor pops!!!! Way more BANG for the buck!!!!

This is just my personal opinion and it applies just to the GTM SC Kit Stage 1. This is just my 2 cents and is a long read. There is more to your decision of Stage 1 or 2. There is a lot involved with going FI on the 370z. You might already know this information but it might be helpful for others making the same decision. I have been on the GTM Stage 1 kit for 5 months and have put 6k on it since the install. The only problems I have encountered with the kit were 2 oil leaks and a slight idle problem. Other than that, knock on wood, I have been extremely happy with GTM and the SC impresses me every time I drive the car. Decisions, decisions …. Several people have asked me about the SC decision and this is what I tell them. You have to make some important decisions about the direction of the performance of your 370 up front. If you start out with the standard bolt-ons and then go FI, you are going to waste a lot of cash. So up front, either decide to stay NA or go FI. I also like the fact that the Stage 1 is low impact on the car. You have to look to even know it is installed. It looks like aftermarket air intakes. 75% of the people who look in my engine bay cannot find the SC. No kidding …. The next decision is you have to make a personal commitment to the additional cost of the supplemental parts and potential labor to support the GTM SC kit. This is no negative on GTM, but they sell a turn-key FI kit. That kit includes all of the FI parts, but does include the supplemental accessories I think are necessary to help ensure longevity of the motor. Again, this is just my opinion. Supplemental Parts The fact of the matter is the 370z runs on the hot side for coolant and oil temperatures. You as the customer need to decide what you want to install to keep your fluids at an acceptable level. I live in Texas and we had record heat last summer; thus, my car suffered with some high oil temps. GTM does offer a great selection of parts to supplement the kit. I am specifically talking about upgraded cooling fans, shrouds, radiator, and a myriad of oil cooling solutions. I think it would be a good business decision to add options to the SC kit that include some of these cooling solutions at a reduced price rather than adding them after the fact. I know some of these parts are new and just released so maybe that is in the works. So I decided up front I was going with the GTM SC kit. The Stage 2 had just been released but I went with the Stage 1 for several reasons.
Maintenance The next commitment is a higher standard for regular or routine maintenance. If you are used to driving your car around and doing little to no maintenance, any FI is probably not for you. What do I mean by higher standard of maintenance?
The whole point I am trying to make is when a NA car is stock, you can neglect checking a lot of things and the car still runs relatively well for a long time. With bolt-ons, other than from an emissions perspective, there is not a whole lot of maintenance required on the parts. With any FI install, there is a lot more going on, so you as the responsible owner must decide if you are in or out or what has to be maintained to keep the grin in your face when you mash the accelerator. Hope this helps with your decision. GTM is a great vendor and source of information. Sam and Mike have been most helpful with me during the entire process including service after the sale which is very important to me. I am right at 380WHP on a conservative tune from SAM on a dyno pull in 115 degree heat. I hope to have a full tune done in the late winter or spring and come closer to the 400WHP mark. |

Always go for that stage 2.

There is a middle ground. Go for stage 2 and run a bigger pulley for less PSI. That way you have the potential to go bigger but you can detune to your comfort level.

I put my stage I GTM SC kit on around 19k miles and currently the car has around 35k miles.
No problems so far other than I have burned through tires faster. I keep up with regular maintenance and check the car out as often as I can to verify everything is working 100%. At the end of the day, your tune and maintenance will determine how well the kit/car last. Does not matter if you drive 5k or 35k a year. Currently at 400whp.
