Herb came to ZCG for a full Koni dampers install and new T/C rod bushings followed by an alignment. Does your G’s tired suspension need updating?

Tetsuya is a long time customer and visited ZCG years ago for an UPREV tune and Bassani exhaust system on his pretty 2005 350z. He recently came back for some suspension upgrades and we happily obliged. We installed TEIN StreetFlex coilovers combined with their latest EDFCactive dampening controller:

The StreetFlex dampeners are trick parts with pillowball mounts and 16-way adjustability. The
“active” EDFC offers two new features in addition to the totally redesigned interface. With the on-board accelerometer, dampening can be automatically adjusted based on g-loads and a GPS unit enables speed-sensitive adjustment!

 

The EDFC unit was mounted neatly in the Z’s NAV/cubby:

 

To handle braking duties we installed a Stoptech Big Brake Kit (332mm) finished in red up front and color matched the stock rear calipers on new Stoptech rotors. Everything is framed nicely behind the new Volk 57xtreme 19″ wheels:

Tetsuya’s Z is now a well-rounded sports car that will surely bring more smiles on spirited drives!

You might remember this stunning S30 we featured a few years ago on our For Sale page that later made its way to our friends at Bring A Trailer. The metallic green color, tan interior and Appliance mesh wheels really give the car an irresistible 70’s vibe.

Several years ago we worked on the Z with previous owner Zack L prior to its sale. You can imagine how happy we were when new owner David J brought “THE 73 Z”  back to ZCG recently. It was running rough and David also wanted to tidy up the engine bay as well as a few other items. While sorting the driveability issues we found the crank pulley dampener was slipping making it hard to set timing. A new factory piece was installed:

  

The carbs were gone through and dialed in. A full tune-up was performed including NOS OEM spark plug cables and intake/exhaust manifold gaskets. This Z is so gorgeous on the outside that we wanted to make it just as nice once the hood is opened. The engine bay was treated to full powdercoating and zinc plating services, new clutch hydraulics and a refreshed radiator.

 

Here is a look before and after…an engine bay worthy of its shiny exterior!

 

We replaced the factory exhaust manifold with an MSA ceramic-coated header followed by our ZCG custom 2.5″ exhaust system with stainless resonator and slash tip:

 

Old twice-pipe setup:

 

Our ZCG upgraded door seals were installed and door fitment sorted to eliminate that “tinny” sound S30 owners commonly experience:

 

The fuel recovery system needed attention so hoses were replaced and tidied up:

 

Wheels undoubtedly make or break a car’s aesthetics. The dealer-optioned Appliance wheels originally fitted definitely look just right and maintain that vintage feel. David chose a set of Rota RB wheels to add a little modern flair and more rubber to the road:

 

With a freshened engine bay and new shoes David showed the ’73 Z at the Brisbane car show:

We loved working on your Z so thank you David for coming back to ZCG!

It’s sedan week! Brandon M’s G35 visited us early 2013 for suspension upgrades and he came back for a few more mods. We installed a Stoptech Sport Kit which is a very smart and affordable way to increase braking capacity:

OEM vs Stoptech rotors:

 

Brandon is now running G35 coupe 19″ wheels and they look fantastic coupled with the lowered ride height!

 

Rob UPREV re-tuned the G with the addition of a Trans-Go shift kit. Note the increased hp/tq throughout entire rev range with peak gains of 10hp/8tq to the wheels:

 

Thanks for coming back to ZCG Brandon!

 

Kevin L wanted to improve the performance of his 2007 Infiniti M35.  Thankfully this large, 3rd-generation sedan sports Nissan’s venerable VQ engine so many bolt-ons are available. We started with Motordyne plenum spacer/lower intake and Injen intake:

 

UPREV tuning maximizes the improved breathing for peak gains of 15hp/6tq for a total of 238hp/230tq to the wheels:

 

The M is no lightweight, and driving a little more “spiritedly” can over-tax the factory brakes easily. Kevin opted for the Concept Z Performance Akebono Big Brake Kit (BBK). This kit uses the OEM brake components found on the G37 Sport Coupes and is a direct bolt-on for the M.

  

OEM vs the larger rotors 14″ (F) and 13.8″(R) will definitely help shed heat and prevent fade. Front calipers installed and framed nicely behind wheels:

 

Rear OEM vs BBK:

 

More power and better braking make Kevin’s M sport sedan exciting to drive!
