Each year the Historic Sportscar Racing association (HSR) organizes the largest and oldest event for Historic race cars on the East Coast. It’s called the Classic Motorsports Mitty and it took place at Road Atlanta, GA from April 27-29. We attended The Mitty to provide race support for Randy Jaffe’s #46 BRE Datsun 240z (driven by our hero John Morton) and Alex McDowell’s Datsun Bluebird Coupe and Hakosuka Skyline.

 

Nissan was the featured marque for the first time with John Morton serving as Grand Marshall so naturally every Datsun-fan was drawn to The Mitty. I took a Thursday night red-eye flight from San Jose with part of the ZCG crew and when we arrived at Road Atlanta our paddock was an absolute feast for the senses. Nestled primely across from the front-straight footbridge, we had an impressive display of West-Coast racers, from L to R: The BRE Datsun 240z, BRE 370z, Comedian Adam Carolla’s #44 Frank Monise Datsun 2000 Roadster and Bob Sharp 610, Alex’s Hakosuka Skyline and Bluebird Coupe, the Friselle GTU 240z, Dave Stone’s Frellsen B-sedan 510, Jim Froula’s (Racecraft) Datsun 260z, our friend Glenn Chiou’s VIPS/Loren St. Lawrence 240z and Bob Clucas’ IMSA GTU 240Z.

 

Take a Lap With John Morton

 

At 76 years of age John Morton is still formidable behind the wheel. Here he is piloting the #46 BRE 240z that we prepared around Road Atlanta; the very same track where he won the 1970 and 1971 National C-Production Championships!

 

Well, That’s Racing

The sweet smell of race fuel, frantic adjustments, checklists, and engines blaring to warm-up for the next session all reminded us how much we love racing!  From the on-board video above, you can see the BRE 240z performed well with John Morton at the wheel but what it does not show viewers is the not-so-glamourous side of racing: part failures. The Z ran great in Thursday’s practice but when we arrived at the track Friday morning, Rob told us the engine failed during the first session. He needed all hands on deck. What followed absolutely humbled me; the ZCG crew went to work in a supreme effort to get the #46 BRE 240z alive again for Saturday/Sunday’s races.

 

John Morton Must Race

To get a first-hand perspective of the Z’s revival I asked ZCG Lead Technician, Josh Corwin, to give us the play-by-play of the heart transplant. Please read on to see a video chronicling the events!

1) How, when and why did the engine fail?
It is still too early to know exactly what went wrong with the engine. A complete teardown will be performed to isolate the root cause. I can tell you that during Friday practice, John Morton was accelerating up Road Atlanta’s back straight coming up the hill before turn 10, in top gear at wide open throttle well over 100mph. That is when a major engine component let go resulting in multiple holes being punched through the engine block, affectively turning the engine into a boat anchor.

2) What was the plan to get John Morton back on the track?
Get an engine, put it in the car, put John Morton in the car, and put the car on track. Simple enough, except finding an engine that could perform was the challenge.

As word spread through the paddock that John Morton needed an engine, the Datsun Community banded together, and offers of engines came swarming in.  Multiple race engines and high performance street engines were all up for grabs. All were seriously built engines, but none of them felt right.

Rob’s ultimate plan to excavate a couple E.B. Parkinson motors, like dinosaur fossils, was crazy to say the least. But, going with his gut, the resurrection of a true vintage race engine was put in motion. Half of the crew went with Randy to his storage to look for a replacement motor, while other half, including myself, received the green light from Rob to began the task of removing the expired power plant in anticipation of the Datsun Relics arrival.

3) Technically, what was involved with swapping parts and prepping the 40-yr old parkinson motor?

The old engine came out quickly, as many hands made light work.  It was then tucked away into the back of the trailer, to be disassembled at a later date, as we worked on getting the car ready for its new engine.  Prepping the vehicle was pretty simple, but there were necessary steps and precautions that need to happen to make this a successful transplant.  We only had one shot at this, so nothing was left to chance.

Below, (L): Gary Brizendine and BRE Engine Chief John Caldwell lend a hand and knowledge: Caldwell is confirming the jetting on the 50mm Mikuni carbs.  (R) The original exhaust system from the 1970s is removed from #46. Morton had already blown apart the exhaust tips on the first session!

  

With any catastrophic engine failure, one of the concerns is metal bits getting stuck in the oil cooler and lines. So, first thing is to remove the oil cooler and hoses and flush them out.  Any leftover engine material in the oiling system can destroy a fresh engine in minutes. Luckily, Road Atlanta’s used oil disposal shed also had 2 solvent tanks, which we used to back flush the cooler and clean the lines of any possible debris. While all the reusable pieces were getting cleaned internally, we moved on to cleaning the mess of shrapnel and engine oil that coated the engine bay.  Just as we finished, the oil cooler system came back fresh and clean, and shortly after engines arrived.  We could finally switch gears to the reassembly of the BRE 240Z.

  

The crew brought back two “long block” engines, meaning the cylinder head and engine block had already been assembled. At first look they were identical in every way and definitely appeared to have been sitting for 40 years. Looking closer, we found one of the engines did not have the timing chain installed which led us to use the one that was “more complete.” We put a wrench on the crank bolt and it rotated 720 degrees, smooth as butter. The next task was to take all the undesirable accessories from the old engine. The 40 year old water pump, alternator, flywheel, crank pulley, thermostat housing, oil filter adaptor, and valve cover were all tossed.  We then tackled a quick clean up, removing years of dirt and grim that had built up while sitting.

Sam C lives in San Francisco and heard of ZCG last summer while at a local bowling alley near our shop in San Jose.  His 1973 Datsun 240z had been sitting for several years and after reading zcarblog he wanted to bring it back to life.

  

We performed an inspection and found that the car needed attention in several areas. Starting with the cooling system, all hoses were replaced and a Koyo race radiator installed.

  

The problematic ’73 model SU carbs were replaced with earlier Z-Therapy units. All smog equipment was deleted. An MSA header was installed and the older igntion system was upgraded to Pertronix:

   

In short, we performed a mechanical resotorationthat this car could perform as it should after years of being idle, including a new battery and recharged the vintage air conditioning system. Here are a few pictures of engine bay completed and detailed:

 

With the engine bay sorted we turned to the chassis. The entire suspension was removed, dis-assembled and media blasted before sending off to be zinc’d and powdercoated.  New parts consisted of 5-way Tociko struts with Eibach springs, MacPherson strut bumpstops, T3 adjustable rear control arms, and adjustable T/C rods and new wheel bearings. ALL bushings were replaced including the rack bushings, ball joints and front control arm bushings.

 
A set of gorgeous 16×7 11mm offset Panasports with 225/50/16 Yokohama S-Drive tires was mounted rounds out the chassis upgrades:

 

The ZCG Big Brake Kit

The pièce de résistance of Sam’s restoration is the Z Car Garage Big-Brake Kit for small wheels.  With our pre-production testing finalized, we are happy to install the first batch on several customer cars like Sam’s, Glenn’s and others.

 

 

Following our successful, larger ZCG BBK, this smaller BBK was designed with Tyler from Stoptech as a direct bolt in solution for the 1970 to 1978 S30 Z cars. We’ve been with Stoptech since the beginning and love their products, we even came up with the slogan “Stoptech or don’t stop at all”!

  

Specifics

Calipers: Stoptech ST42 4-piston front & rear race calipers (Alum 6061 mil-spec Type III anodized)

Rotors: 280mm x 20.6 with Alum 7075 hats

Pads: Stoptech 309 sport street pads

As installed on Sam’s S30, the brake kit is beautiful and functional. Track tested under hard racing conditions and rigorous street testing as well. Factory parking brake functionality is retained by operating a dedicated caliper:

   

This big brake kit will fit under 15″ wheels and some 14″ wheels. Once the BBK is available in our online store there will be a complete wheel fitment guide with printable caliper tool. Datsun 510 and Roadster brake kits coming soon!

 

 

Sam’s Z was detailed by our friend at JB Mobile and the paint looks great. Thank you Sam for letting us get your Z back on the road. Enjoy The Ride!

 

 

 

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!

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
