Greg S came to Z Car Garage for some bolt-ons on his HR-powered 350z.  We installed JWT dual pop chargers and a Bassani cat-back exhaust:

 

Intakes before/after:

Bassani exhaust:

 

Let’s take a look at what the bolt-ons do on the dyno. Starting with a baseline of 253hp/223tq the JWT intakes alone slightly increase peak hp/tq, with significant mid and upper rev range gains:

 

Adding the Bassani exhaust yielded greater gains throughout the rev range, netting +8hp/6tq over baseline:

 

An UPREV tune further optimizes these bolt-ons. Look at the huge low to mid-range gains of over 20hp/20tq! Peak numbers are 264hp/246tw to the wheels, a +11hp/23tq improvement over baseline with more power everywhere!

Enjoy the newfound power and sound Greg!

 

Brian K is a Lockheed Martin employee and came to Z Car Garage to have some bolt-ons and aesthetic pieces installed on his 350z. Bolt-on power upgraes included a JWT Pop Charger, Motordyne 5/16″ plenum spacer and the lovely Bassani full cat-back exhaust system:

 

Here are the intake and plenum spacer installed:

 

The stock exhaust compared to the new Bassani dual-exhaust system:

On the dyno we started with baseline numbers of 230hp/229tq at the wheels. Shown below are the gains from the intake+plenum spacer (234hp/232tq) and exhaust (246hp/238tq):

 

 

With an UPREV tune final numbers are 251hp/240tq to the wheels:

 

Brian also wanted to change up a few aesthetic pieces on his Z including the headlights and grille. The new lamps are from Spyder and the grille is a black mesh unit:

Before/After:

Daren S. wanted to make his Infiniti G35 Journey Sedan more exciting to drive on the commute. Better breathing can improve power so we bolted on  JWT dual POP chargers and a Stillen exhaust system followed by UPREV tuning.

The POP chargers also add a very throaty intake sound 🙂

The Stillen exhaust system replaces the restrictive OEM parts and makes getting on the throttle a bit more satisfying:

On the dyno, the intake alone made a noticeable improvement in power from 260hp/235tq to 264hp/243tq at the wheels:

UPREV tuning makes efficient use of these breathing mods for a final output of 276hp/246tq! Gotta love that huge gain under both hp/tq curves:

Whoa is just as important as go and there are many options out there for improving braking performance. Instead of a full-blown big-brake kit Daren opted for a Stoptech Sport Kit:

This is a great alternative to OEM parts. When coupled with our favorite 309 pad and Stoptech 600 fluid this kit is perfect for spirited driving whether it be on your favorite mountain road or commute!

Here is another amazing example of Motorsports bringing a family together. Rob’s wife Astrid had a birthday coming up so it was time for their Daytona Blue ’07 350z ‘vert to get some B-day love. Living off a mountain road Rob and Astrid needed a car that could be both comfortable and sporty. The couple have had their fair share of track days and Astrid has driven in the 24hrs of Lemons race while Rob has a G37 Sport coupe has his daily driver.

The Z came to ZCG for a 30k service with some upgrades to add some excitement to Astrid’s commute. Like most upgrade sessions at ZCG we started with a baseline dyno to see what we were working with:

Once the services and baseline was complete we installed a set of the Injen intakes and a Bassani exhaust system. These 2 bolt-ons gained 20hp/13tq!

Rob and Astrid wanted this Z to be able to handle any curvy road and  the occasional Track Day. A combination of braking and suspension upgrades were installed, starting with TEIN Flex coilovers with EDFC control unit. This allows the driver to pick from 16 levels of dampening force:

A nice compliment to the coilovers is the adjustable sway bar set from Hotchkis:

We installed our favorite brake pads for any sport driving, the STOPTECH 309 in addition to a full brake and clutch bleed with Motul 600.
With the power mods, brakes, and suspension Rob and Astrid should be able to enjoy a track day or drive on any curvy road with a smile on their faces:)

You know its true love when your wife drives a Z . Ashley took a trip out of town and while she was gone her sneaky Z-obsessed husband dropped her ’07 350z off for some ZCG love. A family that Zs together stays together.  First item on the list for this visit was a baseline dyno to see what we were working with, then a quick install of dual JWT Pop Charger air intakes:

The VQ35HR engine responds well to minor bolt-ons and the addition of JWT intakes resulted in an impressive gain of 17hp/13tq! Plus they look great and sound heavenly when Ashley leans on the loud pedal.

Ashley’s Z sports a set of SSR GT3 wheels with stock ride height. Every Z can benefit from a little lowering, especially with aftermarket wheels/tires.  TEIN S-tech springs were called upon to give the Z a mild drop. Pics coming soon!

The last detail was a set of LED side markers that are both stylish and functional for when Ashley needs to switch lanes and pass the slower traffic 🙂
