For classic car enthusiasts across the globe, visiting the site BringaTrailer.com is part of our daily routine.  Z Car Garage has been a big fan of BaT since its inception in 2007, having referred our customers and serviced several BaT auction vehicles. We happily obliged when they reached out to us for help in finding a Z-car to drive cross-country for a historic racing event.

 

Roadtrip to The Mitty

  
ZCG recently announced our participation at The Mitty April 27-29 at Road Atlanta in Georgia. Nissan is the featured marque at this historic vintage racing event, so naturally a Datsun would be the ideal driving partner, right? For BaT founder Randy Nonnenberg, taking a roadtrip to the Mitty in a Datsun goes further than just arriving in style:

“The Mitty has been an event I’ve personally been interested in attending for a long time. I love seeing new racing venues and meeting BaT community members in different parts of the world. I have never been to Road Atlanta so this seemed like a great opportunity to host a BaT Alumni Gathering at the track. The teams from HSR and Classic Motorsports run some very fun events, so we are thrilled to join.

 

As for the car, I have wanted a Datsun for a long time and even though I like the roadsters and 510s, the 240z has always spoken to me the most. Once we found out that both the Mitty and Monterey would be featuring Nissan/Datsun, it was clear that we needed to have one to help celebrate. It also seems like a very useable classic for a road trip and driving events, so we are excited to put it on the road and document its travels on BaT.”

 

Finding the right Z

A few weeks ago Michael Emery from BaT reached out to ZCG looking for a car to make the journey to The Mitty. Rob immediately had the perfect car in mind, our customer Kevin F’s 1973 240z finished in 112 Yellow and affectionately known as the “Gimlet”. This is a Z we have serviced, maintained and modified over several years.

  

After Randy and Michael visited ZCG to inspect the Z, a deal was struck. Kevin had passed the torch on to BaT for the Z’s next chapter in life. We asked Randy what brought him to Z Car Garage:

“We are lucky to have many Datsun fans in the BaT community, so we reached out to them to see who might know of a good 240Z for sale. We checked out a few cars, and the ability to buy one from a specialist clearly became the most attractive option. Rob at Z Car Garage knew of a car that was not only in great condition, but he had done much of the work on the car and knew the history and build very well.
I tend to want to sort out some details to my liking on almost any car I buy, and his ability to make some key changes was a huge benefit. He had the wheels I wanted in stock, had the know-how to make some components swap quickly, and most importantly was able to ready the car for immediate use. All this plus the car was terrific in person!”

 

Preparing the Z for BaT

 

As Randy mentioned, he was particular about how he wanted the Z to be set up. We addressed his list of needs and performed a total vehicle inspection to ensure the Z was ready for the long journey from California to Georgia.

 

By request, the front valance was returned to stock, 16″ Panasport wheels mounted and stock steering wheel installed.  Kevin had kept the original front valance parts making installation straightforward:

  

16×7 Panasport wheels with 225/50/16 tires:

 

A stock steering wheel replaced the aftermarket unit:

  

The car was mechanically sound needing only a new clutch M/C and slave. We flushed and replaced fluids with Stoptech 600f. The exhaust was adjusted to increase clearance near the larger R200 diff cover. A new windshield and stainless trim pieces were installed:

 

A few detail items like underbody coating and cleanup:

 

Finally, the Z’s ride height was adjusted and engine health confirmed on our dyno. Looking perfect! More pictures in the gallery:

 

On the dyno the 2.7L made a stout 191p/181tq to the wheels:

  

Listen to that triple-carb’d L-series sing in the video below! You can also see Randy driving off from the shop:

 

 

We were curious how Randy felt about his new Z car, asking him how it compares to his Euro/US cars of the same era:

“I drove the car away from the Z Car Garage shop and was instantly pleased with the purchase. The modified 2.7L in this car has great power and sound, and I like the low seating position and long hood to peer over from the driver seat. I’ve spend plenty of time in early 911s, BMWs, and muscle cars from the same era and with these modifications the S30 can run with any of them. I can’t wait to enter this car in some fast road events with my buddies who all drive European stuff. I think they will respect this car quickly.”

 

 

My last question for Randy was to see how Z fits into BaT’s very own car collection:

“Just like you can see on our website, we have very diverse (skitzophrenic?) tastes in cars, trucks, projects, and types of vehicles. We wanted to add a car that was turn-key, could run well on road events, was an iconic design, would represent BaT well, and was in impressive condition. This 240Z checked all those boxes. Plus we don’t currently have a fast 70s coupe in the stable, so our team was excited for this one to arrive.”

Follow The Z!

 

The BaT 240z has already begun its journey to The Mitty! Look for real-time updates along the way from Michael and Randy as they visit BaT buyers, sellers, and community members to hear their stories:

 

Pictures and videos will be posted on BaT’s main site, Facebook and Instagram accounts. We are looking forward to seeing BaT at Road Atlanta with fellow Datsun enthusiasts. Big thanks to Randy and Michael for letting us be a part of their trip.

LONG LIVE THE Z!

 

UPDATE

4/8/18: We are happy to report the BaT 240Z is now in Tempe, AZ attending the Copperstate1000 event on chase-car duty!

Glenn is an avid Datsun enthusiast having owned and raced several cars. You might remember his VIPS 240z vintage race car from the Rolex Monterey Motorsports Reunion last year where he ran it alongside our hero John Morton:

 

We also dyno-tuned the Z in preparation for race week. Look for #39 at this year’s RMMR!

  

Glenn loves his vintage race cars and he recently added this B-sedan Datsun 510 to his stable. He plans to race it this year with SVRA, and it also got accepted to the 2018 RMMR event!

 

In preparation for the upcoming RMMR, Glenn visited Z Car Garage to have the B-sedan dialed-in with chassis dyno tuning.

 

Chassis dyno tuning is extremely beneficial for race cars. You simply can’t run your race car up and down a city street to emulate race conditions and “guess” how your engine settings are performing. In most cases our customers have their engines built and tested on an engine dyno, so it is prudent to confirm performance on the chassis dyno before heading out to the track.

 

We run a series of dyno tests for the customer, including fully heat soaking the engine to ensure it can perform throughout the rev range. Glenn’s 510 was optimized for drivability in his desired powerband and like all race cars that get dyno’d at ZCG, his 510 left with more hp/tq! Enjoy the video of a few dyno pulls and listen to that L-series sing:

 

 

We can’t share numbers as racers like to keep them close to their heart, but you can count on the 510 being ready to rock in the B-sedan group at big race. Thanks for letting us tune your Datsun, Glenn!

 

We have been working with Carlos for several years to raise power levels on his 2015 Nissan GT-R while retaining the stock engine and transmission. On his last visit to ZCG we installed USDM turbos from SIR, bolt-ons and performed an ethanol tune.

 

This time Carlos was ready to hold that boost for a little bit longer. We reached out to Bill Guthrie of SIR and purchased his upgraded actuators matched to our turbos. Originally we had not installed the actuators, trying to keep the boost level down to minimize stress on the engine/tranny. As we all know, the boost fix can last only so long! Carlos came back to ZCG for additional upgrades including an HKS transmission cooler and larger, single FMIC from Boost Logic.

 

  

Acuators:

 

Transmission temps are the enemy of high power levels and track duty for the R35. We installed an HKS transmission cooler and we are really impressed with its quality and performance.

 

You can also see our installation of this HKS cooler on Dan J’s R35, and he reports zero trans temperature issues on the track!

   

The dual intercoolers from the factory were replaced with a single, larger unit from Boost Logic:

 

OEM vs single:

 

Installation of the FMIC:

  

On Carlos’ last visit the R35 put down 611hp/520tq on 91 octane and 703hp/621tq to the wheels on E85. With the new actuators and FMIC it now makes 661p/590tq on 91 octane and 774hp/653tq on Ethanol.

91 Octane:

 

Before tuning on E85, 759p/628tq:

 

After tuning on E85, 774hp/653tq:

 

Allowing the boost to be held to redline resulted in high-end gains in both hp/tq. We can make more power at these boost levels but we are being conservative until we can do a proper built engine/tranny. Enjoy The Boost Carlos!

 

 

Scott visited Z Car Garage for dyno tuning of his Datsun 510. He had the engine installed by our friend Troy Ermish and wanted Rob to perform the final tune/sorting.

 

When you have a shop perform an engine install it is critical to have it tuned and confirm power/drivability.

 

On the dyno baseline numbers were 129hp/129tq at the wheels. With tuning we picked up 11 hp and 9lb-ft of torque for a total of 140hp/138tq to the wheels:

Scott is coming back to ZCG next month to get a larger exhaust installed as the stock exhaust is definitely limiting output.

 

Steve M lives in the North Bay and has a really sweet collection of cars. His favorite car has always been this one-owner 1972 Datsun 240z with 50k original miles. Before we describe how Z Car Garage brought it back to life, let’s hear the history from Steve:

Back in mid-70s I was a car-crazy teenager already working on cars, buying and selling them, and always dreaming of my next sports car. With all the money I had saved from my paper routes I purchased my first car for $500, a red 1965 Ford Mustang and later a 1964 Triumph Spitfire.  Shortly after I acquired these two cars, my parents moved. Our new next-door neighbor, Bob, had an amazing 1972 240Z that was white with a red interior. Other than an early E-Type Jaguar, I thought that the 240Z was the most beautiful car I had ever seen. Bob had bought it new, driving it mostly on weekends. I wanted a Z of my own.

 

Eventually I bought a midnight blue 1971 240z and Bob and I started to figure out ways to make our cars faster. We did everything ourselves from headers to suspension work. We even took a trip down the peninsula to FAR Performance to see if they might sell me a race engine for my Z. Bob was an avid sailor and he had the “240Z” of sailboats: A 505. These dinghies were really fast but they needed a two-man crew and he asked me if I wanted to learn to sail. I said yes, and it wasn’t long before Bob and I had become the best of friends. I went through high school and college. Racing sail boats with Bob on the weekends, cars on the street and vintage cars on the track. I kept buying, fixing up, and selling cars. But in the early 1980s I sold them all, including the Z, an old vintage race car, and even an old E-Type Jaguar, to move to Europe for a few years.

 

 

When I returned, I started my own business and it went well enough that I was able to start another with Bob. Unfortunately, soon after it was evident that our first venture was going to be a home run, Bob was diagnosed with a very rare neurological disease. Within a year he had passed away, leaving his widow and two young sons. In his will, he asked that I take his sons out on my sailboat, to the spot in the San Francisco Bay where he taught me how to sail, so they could spread his ashes there.

 

 

Then one afternoon I received a call from Bob’s wife, Susan. She called my office to ask if I would be there that day and I looked out of my office window to the street below, as a flatbed truck was hauling Bob’s 1972 240 Z to my home. Bob and Susan’s boys had grown, married, and had kids of their own, but they all graciously decided that Bob would have wanted his Z to go to me. Over the next few of years, I managed to get it up and running, but don’t have the time I once did to tinker with cars, so never got it running as well as it deserved because it had been sitting for decades. 

 

Making Steve’s Z a well-sorted driver

 

 

Steve brought his S30 into Z Car Garage in December 2015 and we essentially went through the entire car top to bottom to make it a good driver. He expressed his goal for the restoration and we worked with him to achieve it:

Rob seemed to be able to do miracles with my limited budget. Our plan was something akin to my plan in the 70s. Suspension and exhaust came first, then carburation, tranny, wheels/tires, then a bigger better engine, and a replacement of the Webers with Mikunis. Suddenly, the monster is back… only this time, it is under the skin of a totally stock 1972 Datsun 240Z.

We performed a full engine tune-up and got the car running after many years of sitting idle.  The Z received a suspension refresh with 5-way Tokico struts, Eibach springs and a sway bar set from MSA. All bushings were replaced including T3 lower control arm bushings and new ball joints. The exterior was treated to Paintless Dent Removal and a new PPG windshield was installed.

  

Completing the vintage look are a set of 16×7 Panasports with 225/50/16 Yokohama S-drive tires. At Steve’s request we also installed a BRE spook.

 

That lovely red interior was revived with new seats and a carpet kit:

  

The engine bay and drivetrain needed some attention as well. Cooling system issues were addressed by correcting several leaks, installing new hoses and a Koyo race radiator.  The L24 was mated to a 280Z 5-speed transmission and clutch. New triple-Weber carbs were installed and fed by our ZCG fuel line. A ZCG heat shield protects the carbs from a new MSA exhaust header that was finished with our custom exhaust system:

   

 

Despite the new Weber carbs we did not make power we were hoping for since the L24 was tired. All the work that was performed on the entire car made Steve happy, and he enjoyed the Z for a few years knowing a more powerful engine upgrade was in the works:

Everything about the form and function of this car is beautiful, and you have made it even better than originally intended. The smells, the sound, the feel, are all just right. The throttle response, the smooth shifts, the braking, and especially the handling are awe inspiring.

 

Time for more power

Fast forward to early 2018 and Steve had been enjoying this wonderful Z car since we worked on it. Over the last year Rob had been collecting parts and found a nice L28 engine that would be perfect for Steve. We removed the L24 engine:

  

Steve’s old L24 (left) and the refreshed L28 (right):

 

We gave the L28 a little refresh with a small cam and nice bottom end parts. The engine block was cleaned and painted Nissan Blue. A Mallory Unilite distributor and 280zx starter were installed:

  

 

A key change was switching from the new Weber carbs to triple phh44 Mikuni’s.  This set was sourced from customer Tim N’s 240z as he is getting EFI.

  

With the new Mikuni’s and everything reinstalled the engine bay still looks great:

 

The Z ran extremely well with the Mikuni’s and combined with Rob’s tuning this Z had a dramatic boost in power. On the dyno the old L24 with Webers made 141hp/147tq to the wheels. The new L28 with triple Mikuni’s carbs put down 205p/200tq to the wheels:

 

 

I had a chance to take Steve’s Z out for a spin and it blew my mind. This is the kind of Z that makes me (a hardcore Datsun Roadster fan) want one for myself. It is the embodiment of just enough power, solidness, and vintage feel. Listen to this Z:

 

 

What more can I say? I really love my Z, and consider myself to be one of the luckiest guys on earth, to have found artists like Rob that help me keep my own dreams alive, running; well; and still ripping up the roads.

 

Thank you Steve, for sharing your story and letting us bring your Z back on the road. Tune in for the next chapter as Steve gets ZCG big brakes for small wheels!
Long Live The Z
