In-House GTM Stage 2 SC Install\Tune

Seb@SZ · 11-11-2011, 09:58 PM

We had the opportunity to get our hands on the new GTM Stage 2 SC Kit. The great thing about the kit is that its very quiet not like your typical Vortech units and the way Sam@GTM has designed the kit you can't even see the blower with the hood open. Making it a much slicker and sleeper look. We suggested a larger pulley to keep boost down to a very safe level. However Kevin's already thinking about having us install a smaller pulley to make 9-10 psi! While we were at it we also added GTM's AT Trans Cooler and Engine Oil Cooler to work with the SC kit.

We installed the kit on Kevin's 2010 G37S Coupe AT. Kevin already had an Invidia catback to add to the mix of mods. We added a set of Fast Intentions HFCs since his ART pipes wouldn't clear the new larger tranny cooler fittings and lines.

Nissan\Infiniti has made it hard(er) to service their automatic transmissions. I can see how this would prevent the regular guy from using the wrong fluid and protecting the trans. This is where you fill and check the fluid. No dipsticks here! Sorry Jimmy.

power looks nice and smooth!

Nice. What fuel upgrades come with this kit?

KaienZ34 · 11-12-2011, 09:06 PM

I love everything about this kit but the air filter location. I really like were the air filters are located on their TT kit.

I should probably do this since everyone at the track always assumes I am FI already.

This is an Auto G37 correct?

Yes sir, a 7AT.

looks great!
am I the only one who thinks torque is little bit low relative to power?

Final numbers with 463 whp , 335 tq and I'll let Seb explain the tq

It's proportional to other cars for example:

Over 40 more whp and it makes 35 more torque.

sojirovskensi · 11-13-2011, 12:24 AM

hmm, from the sticky (FI built) I see many members made 400/340 ratio with SC stage 1
Do G37 make less torque than Z?
Or is it because 7AT?
No offense but just curious

The Stage 2 blower makes less torque than the Stage 1 units. Somewhat of the same principle of comparing a small turbocharger to a larger one. Sam was kind enough to let me drive a Stage 1 370Z and is definitely more responsive and torquier.

Take a look at Sam's Stage 2 press release and you'll see the torque differences.

I really appreciate your kind explanation!
I will take a look at it again. I remember seeing it but did not really pay attention to the torque.

No problem!

If anyone is on the fence about the GTM SCs they are fantastic high quality kits that deliver on every aspect of how a proper F.I. kit should be. Quality, performance, and reliability.
