Mark G came to ZCG to have his NISMO Z33 wheels re-finished, T/C bushings replaced and get an UPREV tune. Since his Z was a base model it didn’t have the fancy multi-function steering wheel…UPREV tuning maps can be selected via the steering wheel mounted buttons so we did a complete gauge cluster/steering wheel swap.  The clutch switch was also replaced for the cruise control “cancel” button:

On the dyno, Rob’s UPREV tuning yielded +10hp/10tq  for a total of 270hp/253tq to the wheels. Check out the significant gains from mid-range to redline:

 

Here is another great Datsun family story that Z Car Garage is proud to be a part of. John B’s mother actually bought this 240z in 1978! The Z has been in their family ever since and eventually John became the owner. Unfortunately it had been sitting for a long time as the family changed residences and needed lots of work. ZCG to the rescue! We restored the brakes and suspension which were badly corroded/seized:

 

The front end was treated to new rotors and turned drums, new calipers and T/C rods from Techno Toy Tuning (3T). 3T is a company that helps keep vintage Japanese cars on the road by creating sweet suspension/chassis pieces. We love their products and continue to use them as seen on Grant’s 240z. Here are the old vs new calipers finished in black:

  

The hard, brittle tires and groovy slotted mags were replaced with fresh Bridgestone rubber and 16×7 Panasports. These are the “new” style Panasport castings with a brilliant anodized lip:

 

It is amazing what a little cleaning and some Panasports can do 🙂

Underhood, the engine had a severe exhaust leak. Actually, the entire exhaust system was badly rusted…

A full ZCG exhaust system from the MSA 6-2-1 header back to our trademark slash cut tip:

More engine bay work…the gnarly carbs were fully refurbished and dialed-in. We de-smogged the engine, restored the radiator, replaced the water pump and coolant by pass hoses:

More deteriorated rubber found in the fuel system:

A final touch we are proud of is the refinished cowl piece. ZCG  powdercoats it a matte-black finish that looks fantastic:

 

Dyno tuning produced a robust 140hp/152tq to the wheels:

 

With the engine bay in tip top shape John is ready to hit the road in this family heirloom Z!

For several years we have been helping a group of guys who build these vintage sprint cars to run on the Salt Flats.

Each time Rob has helped dyno-tune these wonderful machines they have broken a speed record in their class!  Check out before/after tuning results:

Just another example of how ZCG loves to help folks in motorsports!

Daniel R owns this 280zx with a turbo swap and it developed a leak from the exhaust manifold. We repaired broken studs in the manifold, injector connections, oil feed to the turbo, replaced the oil dipstick and breather hose.

The valve cover was treated to wrinkle coat red finish:

The engine bay in Daniel’s 280ZX looks better and is fully functional!
