What sparked your interest in Z Cars? For Scott W it began when he was about 15 years old, and eventually led him to Z Car Garage:

“My best friend’s brother’s friend had a silver 240z. He would take us to lunch and we had to lay down in the back. From that time on I wanted a Z! I started reviewing zcarblog.com and found a very nice 260z for sale that was owned by an older retired couple. Based on all the work performed by ZCG I met with Rob and I purchased it. The 260z was originally gold with the 5mph bumpers.”

 

Indeed the gold 1974 260z was our very own customer Geri R’s. When she retired and moved to San Diego she told Rob, “If you are not in SD my Z car can’t come with me…please find it a new home.” Scott W visited ZCG in 2013 and purchased the Z, well before the S30’s garnered high prices! He had a very clear vision of building the ultimate Z Car:

“I told Rob my plan was a car that was great to look at but I’m going to drive it! And drive it hard. My goal was to keep it looking 1974-ish on the outside but modern under the skin.”

So we began the process of upgrading an already solid, clean chassis that Geri lovingly maintained.

Drivetrain

The first item we discussed was the engine. Scott wanted more power and Rob suggested a Rebello 3.2L Stroker engine. Supporting parts included an MSA 6-into-1 header,  ZCG exhaust system, KOYO race radiator (custom upper hose) and ZCG heat shield. A few pictures of the engine build/installation with many more in the gallery:

 

Induction is handled by Jenvey individual throttle-body fuel injection, managed by a Haltech Elite 750 standalone system.

 

A NISMO Competition oil pan was installed to cope with high cornering loads from road course driving. Also shown is the Nissan 240sx 5-speed transmission. This “KA24” unit is significantly stronger than early S30 transmissions. It handles the 3.2L’s extra power, and we offer this conversion to customers.

 

When we upgrade the transmission we also install a JWT HD clutch with aluminum flywheel. Helping put the power down efficiently is an OS Giken LSD. The R180 houses a 4.11 R&P and the assembly is setup in-house (by Joshua Corwin). Rounding out the drivetrain upgrades are a set of ZCG CV Axles(shown below)

The completed engine bay. All hoses, hydraulic lines, fittings etc were removed and restored/replaced with new parts. Zinc plating hardware throughout:

 

On the dyno, Rob tuned the Z with the Haltech making 257hp/229tq to the wheels. An improvement from the stock 121hp/130tq:

Chassis

 

Suspension upgrades were next, focusing on the ideal setup for open track days while remaining comfortable on the street. Scott outgrew the Tokico 5-ways and now has Koni Yellows with our Ground Control coil-over setup from back in the day. Techno Toy Tuning control arms, T/C rods and more complement the total suspension restoration. All parts were powdercoated and hardware plated.  We really appreciate Gabriel at T3 and his staff. They make some of the best suspension parts out there for Z cars.

 

Panasport Wheels

 

Custom sized 17×9 Panasport C8 wheels allow us to run a wide 255/40/17 tire at all four corners, without flaring the fenders:

 

Bridgestone RE-71R tires are shown below. The 17″ diameter wheels also give clearance for our ZCG Big Brakes!

  

ZCG Big-Brakes and CV Axles

After driving our customer Lou’s Fairlady, Scott was sold on our Z Car Garage Big-Brakes.

  

Not to be confused with our familiar Z Car Garage Big-Brakes (for small wheels) that we currently offer, this Big-Brake kit was our initial setup from many years ago. Our first collaboration with Stoptech, this 328mm sized kit requires 17″ diameter wheels and the massive ST-42 calipers are finished in bright red. This kit was installed on our OS Giken TC24-powered 240z and a few other customer cars.

 

 

The ZCG Big-Brakes framed nicely behind the black-spoked C8s. We are currently re-vamping this kit using Stoptech’s latest ST-43 caliper.

    

Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. We have over 70 CV axle kits on customer cars and we are stoked with all of the positive feedback.

   

Scott’s 260z received ZCG CV Axles set #250

  

More pictures of the ZCG axles installed, also visible are the T3 control arms and ZCG exhaust system:

  

Comfort

 

Scott’s 260z had an interior in fair shape. We gave it the full ZCG treatment with a refurbished dash, new carpet and creature comforts like Bluetooth, radar detection and functioning HVAC. In-progress shots below with more in the gallery:

 

New carpet throughout, integrated speaker box in hatch:

 

The stock seats were in bad shape Scott was sliding around on them so we upgraded to leather Recaros. Perfect for keeping him locked in place during track days.

 

The heater system from core to blower was completely restored:

 

Full A/C setup using a smaller Toyota compressor with existing A/C parts:

 

Performance

 

Balance. This Z has power and the chassis upgrades to transform it into a well-rounded sports car. Remember Scott’s goal of building the Z to drive really hard? He has been taking his S30 to Buttonwillow Raceway every month, putting our ZCG products to the test on the track.

 

Enjoy the sounds of Scott’s Z in this short video below:

 

 

Exterior

 

You didn’t think we would forget to mention the total paint color change, did you?  About six months into his build Scott called to request a color change from gold to a Mercedes-Benz shade of Gun Metal. Our man William painted the body, retaining all side-markers to maintain a stock look:

 

Scott however was adamant about changing the stock impact bumpers. Rob located Euro-style 240z bumpers and had them sectioned/re-chromed:

 

Thank you Scott for letting us build your Ultimate Z Car! We are proud to see you enjoy it on the track and street.

LONG LIVE THE Z!

Even though things have been crazy with all of the R&D work we have been doing lately, time has been found to install a few new items on the GT-R and head off to the track!!  The special thing about this particular outing is that it was ONLY for GT-Rs!  Entry was limited to twelve cars and we were lucky enough to make our way into the group.

I would at this point like to mention that we have been working super hard on getting our own ZCG harness bar made and installed in our GT-R.  This track-day is the first time it has seen battle and it worked perfectly.  Our design is much simpler than the competition’s bar (as seen in the AXIS Wheels GT-R) but there will be more on that later on in this post and a follow-up post with pictures tomorrow.

Our day began with Rob, Fred, and myself meeting at the shop in San Jose at 4:30am.  Not much sleep last night.  We packed up our previously prepared “track-day kit” (tools, jack, spare wheels etc.) and headed on our way to Buttonwillow Raceway.  We got to the track at 7:45 and met with the group for a few minutes before the drivers meeting.  Since everyone in the group knew each other, thanks to the small GT-R community, the track rules were fairly easy going and allowed for a ton of freedom.

The plan was to have six cars go out in half hour sessions but as soon as the cars were warmed up they were all out on track.  With such a small group though no one seemed to notice because we would be running track configuration 13 clockwise which has a length of almost 3 miles.  Nice.

Throughout the day cars would pull in and out of the pits as they pleased.  There seemed to be multiple driver, wheel, and camera equipment changes in a few camps besides our own.  It was good to see owners and drivers out and experimenting with the cars.  We personally went through three or four drivers throughout the day and went as far as inviting a professional out for the day to see what our car was capable of in some truly gifted hands.

As you can see from the early photos of the day we were running our one-off set of HRE wheels but tire rubbing issues (due to limited available tire sizes) sidelined the new Nittos we acquired a week earlier.  So after two sessions we were back on the the stock wheels with the OEM Bridgestone run flats.  These tires held up all day in full beat-down sessions without issue.  It’s amazing how professional drivers know how to take care of tires (anyone remember that scene from “Days of Thunder” with Bobby D?)

We managed a best time of 2:02 on the stock wheels and run-flat tires, quite the accomplishment.

Update:  We went through the lap timer this morning and found a 2:00 lap which took place in one of the very last sessions of the day.  How crazy is this car going to be when we get some real rubber?!

Keep reading for the entire event report and more photos.
