GTM Stage 1 SC Turn Key 2011 NISMO
 
I know the GTM Stage 2 kit is hot right now, but I opted for the Stage 1.

Hardware prior to installation:
Completely stock 2011 NISMO

Hardware:
GTM Stage 1 Supercharger Kit Turn Key
Motordyne ART Test Pipes and the OEM NISMO exhaust


~260 on a Dynojet (will post picture when it is available)

The tear down pictures so far. Sorry but I only had a camera phone.

Awesome! Looking forward to updates and your driving reviews.

Good to see you're sticking with the Nismo exhaust... I am doing the same.

Mkai0 08-13-2011 03:22 AM

Looks Good! I noticed two coolers, one for the tranny and one for the engine I'm guessing? How long did the install take? I'm still waiting on mine it's been in the shop for 6 days now!

Oil cooler and the other is a Rotrex traction fluid cooler. The said it would probably be Monday so 4-5 days.

Nothing wrong with a stage 1, it will be plenty fast. Enjoy the boost, and the spring when it gets there :tup:

Jamaica 08-13-2011 12:02 PM

Looking great so far!

theDreamer 08-13-2011 12:03 PM

In for the finished build.

Mike 08-13-2011 12:42 PM

Nice! I remember way back when jotech built the first custom twin turbo 350z

wind.zero 08-13-2011 05:13 PM

I stopped by today and they have made a lot of progress. The SC, Rotrex cooler, the engine accessories, and drive belt are now mounted. They are having some fitment problems with the IC piping. It is a really tight fit but it looks good so far.

I cannot wait to drive it. This will be my first car with boost. That might be a bad thing.

Mkai0 08-14-2011 03:33 AM

Can't wait to see the final product! Day 7, still waiting for the shop to finish installing my GTM Stage 1.

wind.zero 08-15-2011 11:21 AM

Just got some better pictures from Kenny. Ty is moving along on the install.

Nikkolai 08-16-2011 05:42 PM

Awesome! I've been really interested in the GTM SC kit. I'm willing to take it to a shop for the install and I've been told good about Jotech. It's a little far from where I live but not too bad. I just dyno'd my car this Sunday too. It put out 279whp on a Mustang dyno and for some reason they didn't hit rev limit and stopped at 7k. That's maybe a couple more hp, lol. All I have is ERZ HFCs and K&N Typhoon.

DIGItonium 08-16-2011 05:46 PM

Congrats! Can't wait to see and hear it running! Very clean install.

weiboy718 08-16-2011 06:13 PM

Congrats and looking good!

They were adding fluids today and the goal tomorrow is to break the SC in on the dyno and then do some full power pulls. Kenny is going to do a road shake down and I hope to take it home for some fun.

Thanks everyone. I hope to have more pictures and video soon.

wind.zero 08-18-2011 07:54 AM

Ok I got the car back last night. However, due to extremely high temperatures (110+ F) on the dyno, I am driving on a conservative tune. The tune is running rich on the top end and no amount of cooling was going to help indoors with that amount of ambient heat. Unfortunately, I live right in the middle of the infamous 2011 static high pressure system over Texas. The good news is I am going back early Saturday morning for the final tune on the dyno plus a picture/video session.

The 370Z was easily the most powerful car I have owned. So to me it was like one of the big dogs on the street. After the GTM Stage 1 Supercharger, it is like the big dog wielding a beat down stick. All I can say is WOW and this is on a conservative tune. I have not had a lot of time to drive it, but I can say it is impressive. Score for Jotech on the install and for GTM for the kit.

I was very concerned about an increase in cabin noise. I knew there would be a trade off somewhere. However, the Rotrex is extremely quiet. I can hear it but it is certainly not obtrusive in the cabin. Also, I can hear the pressure relief valve but that is quiet too. Surprisingly, I am really happy with the Motordyne ART test pipes with the NISMO exhaust. I honestly cannot tell that much difference in sound in the cabin and I know they will quiet down even more after the break in of the ART pipes. I have not detected a fuel smell either, but then again, I have only put about 30 miles on the car since going FI. Overall, I am very happy and impressed.

The only thing I am somewhat concerned about is the oil temperature. Prior to the oil cooler, my car had gone into limp mode twice when the outside temperatures were well in excess of 105 F. In stop and go traffic the oil temperature was creeping up near 240 on the drive home from Jotech. I sure hope this is just another result of the record heat this summer and not a symptom of some underlying problem.

Final parts list:
  • 3,450 miles on the odometer
  • GTM Stage 1 SC Turn Key kit
  • GTM 25R Thermostatic Oil Cooler
  • Motordyne ART test pipes
  • Eneos oil change
  • Red Line MT fluid change
  • Red Line Differential fluid change

congrats!

roplusbee 08-18-2011 09:08 AM

:iagree:

DIGItonium 08-18-2011 09:31 AM

Congrats! Everything looks very clean - car and install! My car is in Houston, and the install is nearly complete. Next up is the little [tedious] things like gauges and rear camber. I guess it's almost as hot. At home in KS, it's going to be 100+ as well. [sigh]

Nikkolai 08-18-2011 10:28 AM

Is upgrading to a 34 row oil cooler possible with this setup?

Looks to be a 25R.
Same as I have, been running the stage 1 for over a year. Oil temps stay under 220 during daily driving situations, even sitting in stop & go traffic.

I have the 25R from GTM designed to work in conjunction with their SC kit. I do not think I can upgrade to the 34R but I am not certain on that. Last night I was driving light~light in heavy traffic and watched the temps creep from 220 up to about 240. I was shifting under 4k and had the AC full blast.

I have gone into limp mode 2x before this project. The first was Austin to Plano averaging 75-80 when traffic allowed and I was 260+ in 105+ heat. I definitely felt a large loss of power. The second time was Bedford to Plano in 110+ heat and I saw 260+ on the gauge. Before the cooler, 220-240 was typical for my daily commute. I was planning on an oil cooler before I started the SC project.

I thought adding the 25R cooler would help substantially but I have not driven enough to tell for sure yet. It has been an unusual summer where I live with the intense heat.

theDreamer 08-18-2011 10:49 AM

I feel you on the heat, Houston is above 100 everyday but my temp gauge is 108-115 while driving from the amount of heat on the roads. I would say my oil usually does not jump up that much thankfully but my intake temps can go from 5 above ambient to 140 very quickly.

red6spd 08-18-2011 11:08 AM

Cool man. I think a GTM SC is in my future. Times are just to tuff right not LOL.

somatic 08-18-2011 11:13 AM

clean as hell install

ANMVQ 08-18-2011 11:39 AM

Congrats man, Mine is in the future also. Two yeasr tho, :/. .

TeamARK 08-18-2011 11:40 AM

Another great build with an awesome Kit.

weiboy718 08-18-2011 11:54 AM

Adding a GTM oil pan spacer may help with cooling the oil also

I have actually considered this because I am not changing the suspension. However, that makes the oil pan awfully low IMO.

frostyrock7c 08-18-2011 12:04 PM

Very nice install. Enjoy!

I have the spacer installed on my car and my car slammed. I haven't noticed any scrape marks yet. I would assume you'll be fine especially you're not lowered

I have been thinking about doing this, another quart of oil is always great to have, but I do agree it sits below the crossmember on our car. While I am sure we will mostly likely not scrap it, I have had a couple things fly under my car and would hate to have it ripped apart.

Ron 08-18-2011 12:40 PM

AM Perfomance oil pan will do something similar but that is 1grand.

While I like that piece and know it is designed very well, $1,000 for that piece is extremely overpriced.

I'll take some pictures of my oil pan on my next oil change. That should help out a little for the guys that's planning on getting one

wind.zero 08-20-2011 11:10 AM

On the dyno and still running really rich. Sam is sending a better tune.

Anxious to see the end result.

Also still have high oil temps. The NISMO bumper just has no air flow. So we are putting together some things to cool that oil down. Still hitting 250 during normal driving.

Kingbaby 08-20-2011 12:00 PM

nostril ducts?

Because of the same reason I want to do something like this to mine when I go FI.
