The unique VVEL system completely controls the intake valves opening and closing events. The VVEL system is exceedingly complicated using two separate rotating shafts driving links that operate eccentrics activating a valve activating reciprocating rocker arm that takes the place of the traditional cam lobe.

2011 Nissan 370Z hybrid sports car

motoIQ Feature; Nissan to launch hybrid 370Z sports car in 2011? (updated, new info! 5/28/09) 

By Mike Kojima

The Nissan 370Z hybrid will be powered by a version of the VQ engine displacing 3.7 liters and an electric motor. A hybrid drive system will use two separate clutches, one between the internal combustion engine and the electric motor with another clutch between the electric motor and the drive wheels. This system will optimize performance and efficiency depending on operating conditions. The new hybrid system will also feature a full plug in EV mode for city type conditions where charging stations are available to maximize economy.

Nissan 370Z Killer Bee dyno test

Nissan 370Z 6-Speed Manual Transmission Parts Dyno Test, We Test Stillen's Exhaust System and High Flow Cats With Technosquare's ECU Reflash

by Mike Kojima

For our test mule, we used the Killer Bee, the yellow 370Z that was our May feature car. The Killer Bee is a sports package 6-speed manual transmission 370 that was returned to stock for our evaluation. We will be evaluating more parts on the Killer Bee in the near future so stay tuned! In stock trim the Killer Bee slung out 262 whp at 7000 rpm and 210 lb/ft of torque at 4600 rpm. The VQ37VHR engine exhibited the typical wide flat torque curve and nice linear power curve that the VQ37VHR is becoming renowned for.

Berk Technologies 370Z cats and downpipes

Berk Technologies Nissan 370Z Downpipes

By Mike Bonnani

When evaluating the exhaust system on the Nissan 370Z we were amazed how restrictive it was.  The tubing diameter is tiny for an engine with the output of the VHR37.  To help address this issue we decided to start uncorking the exhaust system by evaluating a set of high flow Catalytic Converters and Downpipes from Berk Technology.

JWT Nissan 370z Pop Charger

We Test Jim Wolf Technologies Nissan 370Z Dual Pop Charger (NEW VIDEO)!

By Mike Kojima

We used a new six speed sports model Nissan 370Z with a few hundred miles on the odometer as our test subject. Before the installation of the JWT Dual POP, we baselined the car on Technosquare’s AutoDyn 30 Superflow chassis dyno. The Superflow dyno is unique in that it uses both an inertial weighted roller and an eddy current load cell to provide the working load against the engine.

Nissan Engineers discuss design of the 240Z

motoIQ Feature; The History of the Nissan Z From 240Z to 370Z 

By Annie Sam

When the ten engineers of Nissan gathered together to conceptualize the design of their next sports car line back in early sixties, we wonder if they ever fathomed the idea that their little clay mock up would grow to hold the title of "Best Selling Sports Car Series of All Time". From the first generation Fairlady Z/Datsun 240Z  to the newest 370Z, the Z car has earned its notoriety in automotive history.

Technosqaure Nissan 370Z Infiniti G37 ECU reflash dyno test results

Technosquare's Nissan 370Z/Infiniti G37 Performance ECU Reflash Released (NEW VIDEO)!

By Mike Kojima

Technosquare changes the factory fuel, timing, rev limit and VVEL/VTC cam control maps to get a respectable gain of 11 whp and 10 lb/ft of torque. The gains are pretty much across the board, starting at 2700 rpm and continuing until the rev limiter stops the fun. The gains are large and consistent through the entire rev range, greatly increasing the area under the power curve.

Technosquare Nissan 370Z oil cooler

Technosquare's Nissan oil cooler kit solves hot oil Issues

  By Mike Kojima 

Since we have actually started to work on and modify the Nissan 370Z we have come to realize that high oil temperatures have the potential to become a problem on these cars. We have recorded oil temperatures of 260 degrees plus on 370Z’s on the dyno, in brisk driving and simply in heavy traffic. Several times we had to stop dyno testing or slow down while driving to allow oil temperatures to drop.

Dyno test 370Z Stillen exhaust, Stillen cold air intake, Beck high flow cats, Technosqaure ECU reflash

Nissan 370Z Auto Tranny Performance Part Dyno Thrash-a-thon!  We Test Stillen's cold air intake, exhaust, Berk high flow cats, Technosquare ECU reflash 

By Sarah Forst

We strove for accuracy and repeatability in our testing. We did all of our testing during one day. We used standard SAE correction. We thoroughly warmed up the VQ37VHR engine and the drivetrain by driving the car on the dyno at speed for about 10 minutes to warm the engine, transmission and differential oil (this car is equipped with Technosquare’s oil cooler kit) as well.

Blue Nissan 370z

motoIQ Feature; Nissan 370Z Driving Impressions

MotoIQ Staff Report

Most web publications have not been able to get a good hard look at the Nissan 370Z, but recently we were lucky enough to give a pre-production six-speed manual 370Z with a sport aero and brake package from Nissan's test fleet a short test drive. In that short test ride we were quite impressed with the 370Z's refinement and capabilities.   Frankly, we're amazed at what Nissan has done to the Z in this latest iteration despite being jaded, hard to impress car guys.

motoIQ Feature; An American Japanese in Tokyo

By Mike Kojima and Aaron LaBeau

A Vacation at last I think… as I sign up for a trip to Tokyo in the middle of January.  I have flown to Japan with the folks at Turbo magazine and Nitto tires many times over the years and this disastrous year, I need a break from the hectic pace of being a number one stunna.


 

Nissan 370Z Suspension Technology

Nissan 370Z Suspension Technology, A Look Underneath the 370Z!

By Mike Kojima

Thanks to Edmunds.com, we were invited to the first public viewing of the Nissan 370Z.  While other Journalists busied themselves by jostling for a chance to photograph the outside, sit inside or eat the tasty burritos and tacos provided for the event, we got down and dirty, crawling on the ground to look at the underpinnings so we could try to get a more technical view of the car.

Got a Tech Question?  Ask Sarah!

Email asksarah@motoiq.com

By Sarah Forst

I have a 1996 200sx Se-R and I had a GTI-R Pulsar motor put in it. I want to upgrade the brakes.  In your book, “How to Build Performance Nissan Sport Compacts,” you mention some upgrades. One in particular is the Fastbrakes upgrade kit for the front brakes that uses NX2000 (AD22VF) calipers, rotors, and pads. And for the back brakes upgrade kit, using the 1995-1999 Maxima rear calipers, rotors, and pads.  Are these all the parts that I would need if I were to buy them from an auto parts place?
