On the cover of the current September issue of Classic Motorsports Magazine is Randy Jaffe’s BRE Datsun 240z. The 12-page feature on Peter Brock’s racing history with the Z also discusses Randy’s restoration of the famous #46 car. We were very happy to see Z Car Garage mentioned in the article after our efforts to support John Morton racing #46 at The Mitty earlier this year. Pick up a copy soon!

Z Car Garage is also in Grassroots Motorsports Magazine in the August issue:
We are excited for the 2018 The Rolex Monterey Motorsports Reunion where John Morton will be racing the BRE Datsun 240z again! You can see our report from last year’s RMMR HERE.
Need help planning for Monterey Car Week? Classic Motorsports has a great guide to all of the events during HERE.
The ZONC Annual Car Show will be held Saturday July 28 in Brisbane, CA. This a fun event in a great location so bring out your Z, G, Datsun or GT-R! Pictures from last year’s show can be seen HERE with more details below. Z you at the show!
Hagerty recently produced a video featuring local Bay Area Datsun owners Courtney and Dustin Frisk. The couple got married last year and Z Car Garage prepared Courtney’s 240z in time for their special day. Check out the video below and find out more about their love for Datsuns in Hagerty’s article HERE.
Learn more about ZCG’s work on Courtney’s 240z HERE. Enjoy The Ride, you two!
Ty and Christine also joined us in their 991 Porsche:
Naveed has a cool collection of sports cars including an Nissan R32 Skyline and recently acquired this Fairlady Z:
He has been driving this S30 religiously and organized the day’s fun run, starting in Cupertino and heading up HWY 9. It was a gorgeous day to be driving Datsuns!
We stopped at a vista point just after the 9/35 junction and headed to Alice’s:
From Alice’s we drove down 84 and to the coast via Pescadero Rd. Though foggy it was quite warm and we had fun staging the cars for photos.
Naveed captured some great shots!
Naveed’s RHD S30 sported a triple-Mikuni carb’d L20A with a full Fujitsubo exhaust. Stay tuned as we report on the dyno performance of the Fujitsubo exhaust system on our shop S30:
Naveed’s Z sounded wonderful echoing off the forest-lined roads. Listen to the exhaust and watch a short sample of the fun run in the video below.
We had a blast, thanks for inviting us Naveed!

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.
