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:

We are selling our 1971 Datsun 510 Wagon. It features a 2.4-liter KA24DE engine with five-speed manual transmission sourced from a Nissan 240SX. The car is a wonderful driver and recently completed the 300-mile Tokyo Calling Rally in Napa, Ca.

 

It was repainted in its original shade of green with a black vinyl interior and re-chromed bumpers by the previous owner. The interior features BMW E30 front seats, Nardi steering and rare Bluebird center console. New carpet, headliner, door cards were installed and all rubber seals were replaced.

 The KA24DE uses a Megasquirt engine management system. We dyno tuned it, making 148hp/161tq at the wheels.

Paul K is a local enthusiast out of Campbell, Ca and he visited Z Car Garage for basic performance upgrades on his 2011 Nismo 370z:

 

Our client Randy Jaffe is selling his 1972 Datsun 240Z. This is a one owner, low mileage and very original example.

At Z Car Garage we are fortunate to be a part of our client’s sports car journeys. We first met Derek Y in 2014 when we worked on his 2005 Infiniti G35 back. A few years passed by and he visited us with his latest Nissan, this 2015 GT-R:

 

The R35 had only 11k miles and ZCG installed a host of power upgrades from AMS, EcuTek, SpecialtyZ, Turbosmart and more. You can read about this work from 2019, including the E85 flex-fuel and exhaust upgrades all in this previous blog post.

 

More Power and a New Look

 

Derek latest visit was earlier this year for dyno tuning, interior items and AirLift installation. When it arrived at the shop this R35 sported a complete Varis Kamikaze-R Ver. 2 widebody “Super Sonic” kit and Varis Kamikaze-R Ver. 2 Vented Carbon hood. The Air Lift 3H air suspension strut kit was installed with polished 5 gallon tank.

 

We ran all of the air lines, checked ride height and clearances for the slick Advan R6 Candy Red wheels (20×11 +15 front – 20×12+20 rear) with Toyo R888R tires (305/35/20 Front – 325/30/20 Rear), more installation photos in the gallery below:

 

We also installed a new, Overtake 100-V Saikou Exhaust:

 

A few minor items like a new battery, TPMS sensors in the new wheels and a final health check for Derek’s VR30DETT…but first we performed a re-tune with Ecutek for even more power.  Our last dyno session yielded 612hp/604tq to the wheels and it left with 640hp/622tq. What’s impressive is that this remains a supercar that’s easy to to drive:

 

Enjoy these dyno runs:

 

Interior

 

Derek had several interior items for us to install including: Mines Steering Wheel, Nismo Cluster, Nismo cluster shroud and shiftter paddles:

 

Derek is happy with the latest upgrades to the R35:

“I have been going to Rob for a while now, he worked on my car october 2019 (bolt on and e85 work done) and again recently with a new tune and air suspension and some interior mods. The work is always great its making more power now and more responsive linear power.”

 

 

Here are the SpecialtyZ 3″ intakes and AMS front-mount intercooler being installed:

 

More engine bay work including the AMS crankcase breather setup, ID 1300cc injectors (plus DW fuel pump upgrade), Turbosmart BOVs and a SpecialtyZ Flex-Fuel kit:

 

AMS crankcase breather being plumbed:

 

Stock vs Turbosmart BOV:

 

On the lift, AMS cat-less downpipes are installed:

 

At first glance it is difficult to catch all of the power upgrades in the engine bay, Stock (L) vs Modified (R)

 

Derek also needed new tires so we mounted fresh Michelin Pilot Sport4S sized 245/40/20 and 285/35/ 20.

Dyno Tuning

Back in 2019 , Rob dyno tuned the GT-R using an EcuTek flash and Derek also received a USB dongle for datalogging. Baseline power was 495hp/446tq with final numbers of 612hp/604tq to the wheels on E85:

 

A few plots showing the tuning session: Baseline to 91 octane tune with gains of 65hp/93tq (Left), and the final E85 tune for even more gains of 52hp/51tq (Right):

Thanks for letting us work on your GT-R Derek and enjoy the boost!
