Bill’s 1973 Datsun 240Z

Filed under: 240z,350z,Maintenance,Performance
by Alvin G @ 2:40 pm on November 21, 2023

 

We met Bill in 2019 when he came to Z Car Garage on referral from our local Z Owners of Northern California (ZONC) club. He’s owned this pretty 1973 Datsun 240Z in Brown Metallic (code 114) for many years and had a list of small things that he always wanted to address. Before we cover the cosmetic and mechanical work we performed let’s hear how Bill got into Z cars…

Bill’s Z Story

 

“When I was about 10, my sister and her husband bought a 1979 280ZX. (They still have it but it currently doesn’t run.) I loved it. I always wanted a Jaguar E type and the Z has a similar shape. As soon as I could afford one, I got a used 1977 280Z and drove it to almost 400,000 miles when I finally wrecked it. I went a couple of months without a Z when a friend told me about a 240 he saw for sale. The owner was a teacher and so am I so of the 3 bidders I got it.”

 

“Then a few years later I went into administration and with the raise I thought it would be fun to have a new Z to go with the 240 so I ended up buying a 2008 350Z. I have had two Zs ever since. The 350 is definitely more capable and is very fun to drive, but I still think the 240 looks better. A really fun part of owning the 240 is taking it to car shows. I get a lot of people saying things like, “I owned a car just like this.” It seems to bring back a lot of memories for many people. Everybody loves the Z!”

Keeping Bill On The Road

 

When Bill came to Z Car Garage in 2019 we re-chromed his rear bumper, zinc plated various hardware, removed smog equipment and cleaned up the engine bay. A failing oil spray bar was replaced and we added ZCG exhaust, header and Z Therapy carb set.

Re-chromed rear bumper:

 

Zinc’d hardware:

 

New exhaust header and SU carb set from Therapy:

 

In 2022 we did more work to Bill’s awesome ’73. We replaced the radiator with a Koyo race unit, installed a Rebello street cam, adjustable T/C rods from T3 followed by alignment services in-house. We also replaced the speedometer seal rings and oil pan gasket. More detailed photos in the gallery below!

We took care of a few more items like weatherstripping and added a set of Holley retro headlights:

 

Enjoy The Ride

 

We have been taking care of Bill’s 240Z and enjoy working with him:

“ZCG does the highest quality work. They are very knowledgeable, honest and you can tell they really love Zs. It’s like they are working on their own car when they look at a customer’s car! It really feels like a new car. It needed a camshaft and some other parts and they did it perfectly. I love driving that car!”

We also take care of Bill’s 2008 Nissan 350Z convertible, to be featured on zcarblog.com soon!

 

What’s in store Bill’s 240Z? He’s always wanted a rally clock since seeing one at a car show 10+ years ago.  Also in the near future he wants to do a drum brakes to disc brakes conversion. Keep Enjoying the Ride Bill, thanks for your support and Long Live The Z!

John’s Infiniti Q50S Red Sport

John E came to Z Car Garage through a dealership connection at Dublin Infiniti. He purchased this Q50S Red Sport in 2019 with 46k miles on the odometer and it was time for bolt-on performance upgrades with dyno tuning.

 

We installed several parts from AMS Performance including their AMS Heat ExchangerAMS Coolant expansion tank. Helping the VR30DDT engine breathe are AMS downpipes and a full Fast Intentions cat-back exhaust system. Photos of each are shown below.

 

The new AMS heat exchanger compared to the stock unit and installation:


AMS expansion tank installed replacing two plastic OEM units:

 

AMS downpipes:

 

The Fast Intentions cat-back exhaust replaces the restrictive OEM system:

 

Standard exhaust tips on the FI exhaust system, we love the quality, fitment and sound of these parts:

 

We also installed new Hotchkis sway bars front/rear. Stock vs new below:

 

Dyno Tuning

Straight from the factory, the VR30DDTT is an impressive motor rate at 400 hp and 350 ft-lbs tq stock. It is actually underrated as we have seen with dyno testing. With a few bolt-ons and tuning, even more power can be unlocked from the VR30. Rob tuned John’s Q50 using EcuTek, making 404hp/435tq at the wheels. A significant improvement over the 336hp/338tq baseline:

Enjoy The Boost John!

TUNING: Josh’s Nissan 350Z

Filed under: 350z,Featured Cars and Projects,Performance
by Alvin G @ 3:50 pm on October 26, 2023

 

At Z Car Garage we specialize in performance modifications and tuning for the Nissan/Infiniti sports cars. Dyno tuning with UPREV or EcuTek software can maximize power gains from individual modifications like intake/exhaust upgrades. Josh M visited Z Car Garage for a dyno tuning session on his Nissan 350Z following an engine swap and we were happy to help him.  Let’s hear about his Z-car story…

Josh’s 350Z V.2

 

“I bought my car back in 2007 after graduating high school. I first heard about the shop shortly after I joined my350z.com back in 2008. After a few years and acquiring a full set of Motordyne bolt ons I finally called up the shop and met with Rob in 2013 to get it tuned. He wisely advised against it with how much oil I was consuming back then and suggested I come back with a fresh motor or rebuild (I’m thankful for his honesty and integrity).”

 

“Last year when that motor finally gave up around 200k it was time to swap all my mods to a new engine and call Rob for a dyno tuning session. My car made great power and surpassed my own expectations when it made 288whp and 274wtq on this swap from an ’04 G35. It’s always felt like a strong DE with a solid powerband and the dyno tune proved it. My main goal for the car is overall balance between drivability on the streets and performance on the track, and using our beautiful Santa Cruz mountain roads as testing grounds has helped me kind of find that happy spot.”

 
 

“As far as the exterior, a mix of KH3 super black and seibon carbon keeps it stealthy but also distinguished in the right light. I’m serious about the overall balance thing and reducing this 2 seater cars weight is a top priority, currently sitting at ~3100lbs and ideally want to be under 3k lbs.”

Dyno Tuning at Z Car Garage

 

A typical dyno session begins with a road test and full inspection before hitting the roller. We found a failed inlet hose and loose plenum bolts so we tightened everything up to ensure a successful dyno pass.

 

We dyno tuned the Z with UPREV and ARC license. Z Car Garage offers this ARC (Advanced Racing Controls) license add-on service to the existing UPREV Flash, allowing adjustable launch control, burnout mode, and flat-foot shifting for $150. This is for cars with manual transmission, VDC/cruise control. Call Rob for more details! Josh’s Z made 288hp/272tq to the wheels, a significant gain over baseline of 274hp/261tq:

 

Turn up the volume and enjoy this video of Josh’s 350Z on the dyno. Thanks for your support Josh and LONG LIVE THE Z!

Z Car Garage Big-Brakes For 3 Datsun 240Z Builds

Filed under: 240z,Parts,Performance
by Alvin G @ 2:40 pm on September 18, 2023

 

We love to see our parts installed on client’s cars. Nino Tecson just received three sets of our Z Car Garage Big-Brakes for three of his own client’s Datsun 240Z builds:

 

Nino was pleased with the Z Car Garage brake kit upon arrival and shared some installation photos from his client’s Series 1 Datsun 240Z:

“Been hearing nothing but good things about this BBK from @zcargarage ever since it came out. Time to put these on some cars. Kit looks great, of course @zcargarage covered the basics, good packaging, no missing parts etc. Looking at the quality I don’t think there’s gonna be any fitment issues at all. Also I know @rawbfuller put in the time and thought into putting this kit together so I don’t have to deal with proportioning valves and brake bias etc.”

 

Nice touch with the Stoptech calipers in “Z” formation, Nino…

 

Nino is also an S30 owner/enthusiast with a very pretty Series 1 Z. You can learn more about his Datsun story in this Speedhunters feature with photos by Sara Ryan:
