GTM Stage 2 SC

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. The heart of the kit is the Rotrex C38 that delivers in Kevin’s setup 7 psi. 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 psi! While we were at it we also added GTM’s AT Trans Cooler and Engine Oil Cooler to work with the SC kit.

Just a turbo driven by a belt 😉

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.

Believe it or not, this is where the intake sits since the blower sits low by the engine. Sam claims and has done testing that inlet air temps aren’t as bad as they would look by having the intake sit right below the passenger exhaust manifold.

Quad cooler monster. On the passenger side resides the trans cooler, top center the SC cooler (SC has its own oil system), below it is the intercooler, and on the driver side the engine oil cooler.

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.

Installed and ready to make boost. You can see the SC oil reservoir by the coolant overflow tank.

It’s hard to see what’s behind the bumper. It’ll make you want to think twice when pulling up to a new G.

460 whp on 8.5 psi. Time to light up the tires.

HR & VHR Clutch Kits

Our final release of our 350Z (07-08 HR), 370Z\G37 clutch kits are now officially available. Our first iteration involved upgrading the factory CSC. This time we incorporated the use of a Tilton racing slave. To achieve the proper release and ensure maximum clutch life the height of the flywheel and clutch pressure plates have been shortened. In doing so we have saved even more weight from our original version.

Max Street Kit shown installed on a NA VHR. You can see the two orangish stripes on the pressure plate and flywheel (balancing mark). We take the time to balance our assemblies for even more engine smoothness.

Our CSC (internal slave) bolts right in with no need for any modifications to the transmission front cover. All it takes is bolting up our adapter plate and your done. SS lines are included for a complete install. We are offering our Max Street, Max 6-Puck, and High 5 clutches. Kits include the segmented aluminum flywheel, clutch disc, pressure plate, racing CSC, pilot bushing, SS lines, and associated hardware.

48 lbs for the factory setup.

31 lbs for a total of 17 lbs saved!

M370 Results

Jason brought us his 370Z equipped with an AT for some dyno comparison on the Motordyne M370 Intake Manifold. Tony @ Motordyne has taken the HR intake manifold that came equipped on the 07-08 Z33s and modified them to work on the VHR engines. The result is improved power & torque up to 6200 RPMs. The runner length is one of the largest differences when it comes to the two intake manifold differences. Results below.

Factory engine cover can be installed for those wondering.

Some nice gains to be had. We saw an average of 7 HP & Torque with a good amount gained between 3800 and 6200 RPMs. At 5K we gained 11 torque and 12 whp.

Swift’ed & Kic’ed

This blue bomber received a set of Swift Springs and Kics 20mm Wheel Spacers. The Swift Springs are an excellent choice for a street driven Z being both comfortable, a little lower, and better handling.

Charles came by a few weeks ago to see what we could do for his topless Z. Armed with a Stillen Catback from the get go, we pointed out that his tips were sticking out way tooooo far. Not a sexy look. We had a quick fix for his hyper-thyroided tips. Charles also had Eibach Pro-Kit springs installed only to suffer from too much negative camber and wheels that sunk far into the fenders like a scared dog with its tail between its legs. This is where we went to work.

We installed a set of SPL’s Camber Links out back along with SPC Camber\Toe Bolts. The new hybrid adjusters on the arms are extremely well made to keep the link from shifting position.

After installing the adjustable rear suspension components we added a set of 20mm wheel spacers front and rear to lose that unsightly sunk in look; followed by an alignment.

After pics:

We followed up the looks and suspension add ons with a tune. Charles has a Stillen Gen 3 CAI & Catback for his performance mods. Some decent gains.

Z34 Swift Spring Install Pics

We’ve done a few Swift Spring installs and here are a couple shots from two 370s we’ve done. Sorry, no “before” pics.

The Swifts still have an incredibly comfortable feel for the daily driver while dropping the Z down 1.25″ in the front and 1″ in the rear. Spring rates are 10.0 kg\mm (front) & 10.5 kg\mm (rear).

Sean’s Z sports the Swifts and also some 20mm wheel spacers on all 4 corners for an even more aggressive stance on Sport Package wheels.

Stu’s 370Z Dyno Tune

Stu brought down his 2009 Z34 for some tuning. He has the Cobb Post MAF Silicone Tubes, drop in K&Ns, and Fast Intentions Catback.

Blue was his baseline and red was after some tuning. Even with these basic mods his A\F was very lean to begin with.

370Z TT…..the way it should be

Back in June I picked up a Z34 with intentions that if I bought one it would HAVE to be twin turbo’ed shortly thereafter. When the new gen Z first came out I wasn’t completely sold on its looks. I hoped at the least the engine and interior were further improved upon than the Z33. As time progressed I began to liken the fish hook head lights, although the fangs on the bumper were still undesirable. In any case, I had the burning desire to feel, drive, and interact with the new generation of Z car. Having played with some at the shop I was pleasantly surprised as to how much better quality was up over the 350Z. Handling is superb while retaining a very comfortable ride that doesn’t bring discomfort to my body. Having owned various high power Zs the added power of the new Z34 was a benefit, but I was spoiled. This is why it just had to be turbo’ed.

Older brother Z32 gets to share his bedroom and share stories. Looking at the rear of the Z34, the only thing I didn’t like was the rear fog light. Painting the lower portion of the bumper black helped detract attention from it.

It’s almost a shame the front bumper has to hide such a beautiful kit produced by GTM.

The kit selected to power the Z is a high quality GTM Stage 2. The turbos used are Garrett GT2860RS’ utilizing the .86 turbine housing and Tial external wastegates. A GTM competition oil cooler was added to combat the already (factory) problematic oil temps.

Engine cover painted to match.

Since the car was to see some drag strip use we selected our flywheel and High 5 Clutch.

6 psi of boost (Boost Controller Off), good for over 400 whp.

9 psi for 488whp.

12 psi (100 octane) for 557 whp. This is efficiency! Less boost than a comparable Z32 and making more power for the given boost level. The one thing lacking versus its older brother Z32 is the torque output. The VG30DETT is good for matching HP & Torque values.

The blue run was the car BONE Stock compared to the red run force fed by 12 psi of boost from the GT2860RS’.

Power comes on very smoothly unlike a Z32 which can be violent. Due to in part by the flat torque output. It feels like the car could have come equipped force fed from the factory, its that good. The VQ37VHR engine acts as if nothing were different with this amount of power running through its veins. Something the old VQ35DE could not accomplish on a factory engine. The bone stock VQ35DE could really only safely muster under 400whp. Anymore and you risk certain catastrophe on the VQDE engine.

On its first maiden voyage down the 1320 the Z and I (CAR #7293) were able to break into the 11s. Prior to this it had been over 5 years since I last banged the gears down the track. I can say this car is limited mainly by my driving and with some practice it should see low to mid 11 E.T.s.
