Nissan's 350 hp Nismo 370Z Model Due in June!

by Sarah Forst

The Nismo 370Z is not only a looker but as you would expect from Nismo, has functional performance improvements over the base 370Z as well. The Nismo 370Z comes with an exclusive, unique and functional body kit that is not available as a Nismo accessory at the dealership. 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 temp issues!

The issue of Nissan 370Z’s running excessively high oil temperatures has been speculated upon since before the cars launch when photos of pre production vehicles fitted with racing style oil coolers started to appear on the internet. These oil coolers with bar and plate heat exchangers, race car AN fittings and braided steel lines were clearly not parts made with production intent. Why did the cars have these coolers, was the question echoed across the web.

We figured that the coolers were just a precaution, installed on press fleet vehicles as cheap insurance against journalistic abuse or for durability in special arrive and drive promotional event use which can be more brutal than racing.

Just a heat machine... The VQ37VHR engine found on the 370Z and the Infiniti G37 runs high oil temperatures. Lots of oil churning caused by its variable cam timing system is the main suspect

Since we have actually started to work on and modify the 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. This is not race track flogging, a dyno run is a very short burst at wide open throttle through one gear, brisk driving is not an illegal balls out cannonball run, its driving a sports car how it was supposed to be driven and heavy traffic is something any car should be able to deal with easily.

260 degrees is the beginning of the danger zone or about as hot as can be tolerated by an engine without risk. At 260 degrees, oil breaks down rapidly losing its ability to lubricate and forming sludge. At this temperature the engines bearings which are made of soft malleable metal start to soften and lose there load bearing capacity. This is the point where damage can start if the car is driven to the limit.

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.

The History of the Z from 240Z to 370Z

The History of the Nissan Z 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.

Nissan 370Z Convertible Hits the Street!

The Nissan 370Z Roadster also uses the Z Coupe’s multilink 4-wheel independent suspension. This suspension setup is a double wishbone 2-link front and 4-link rear suspension, an improvement over the over-complicated articulated lower multi-link setup in the 350Z. The suspension is lighter and stiffer with forged aluminum arms, lighter stabilizer bar offering a 35% improved leverage ratio, and lightweight rigid rear cradle incorporated as a single piece. The rack and pinion steering design is speed sensitive and includes a solenoid valve that damps unwelcome steering kickback and vibrations. The Vehicle Dynamic Control (VDC) system is still a standard feature.

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.
