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. |

 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 Bad News Buzz: High Engine & Diff Oil Temps ~ The $300 Dollar Oil Change ~ Engine Clatter & More! Hype or Reality? by Mike Kojima
One of the main issues is that the 370Z and G37 with the VQ37VHR engine experiences high oil temperatures. The high engine oil temps can cause the engines ECU to put it into a limp home mode where the engine rpm is limited, first to around 6000 rpm and if you don’t start to behave, a lower limit of about 3500 rpm is engaged until the oil temperatures drop below around 280 degree and the key is cycled. The VQ37VHR is very prone to suffer from high engine oil temps during any sort of extended high speed driving such as motorsports events, in racing and even non competition events such as track days.

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. |

The wind tunnel tuned and racing-inspired body lines are fierce with sculptural fenders, upswept quarter windows, vertical door handles, and aluminum hood, door panels, and hatchback. |
 Technosquare's Nissan 370Z oil cooler kit solves oil temperature 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. |
