Greddy Releases 370Z 20G TT Kit!
After months of patient anticipation, Greddy has finally released the 20G Tuner Twin Turbo Kit for the Nissan 370Z! This particular kit utilizes the same pair of TD06SH-20G turbos that have been a great success in the various 350Z engines and the Nissan GTR. At just 6.5 psi, this kit will produce over 400 whp on our Dyno Dynamics. Greddy’s true-dual Ti-C exhaust for the 370Z will help the kit flow even better.
The Greddy kit contains proven components for 400 whp and beyond. These twin 20G turbos, combined with heavy duty cast manifolds, external wastegates, and an extra large front mount intercooler have the capacity to support over 800 whp. This power level requires upgraded engine internals, similar to our various staged packages for the VQ35.
As a full service installation facility, we are able to not only offer these turbo kits for sale, but provide all of the necessary installation labor and dyno tuning as well. We would like to reach out to our local 370Z customers who may be interested in this type of power package. For a limited time, special deals will be available to the first customers interested in purchasing this Greddy twin turbo kit for their car. Please contact us directly for details.
350Z Built HR with Greddy 20G Kit
A local customer of ours had recently purchased a 2008 Nissan 350Z with the relatively undeveloped VQ35HR motor inside. Although this particular engine bridges the gap between the more common VQ35DE and the all new VQ37VHR, it was only produced for two years in the 350Z, and lacks the amount of aftermarket options seen in other versions of Nissan’s VQ platform. However, this would not prevent us from porting our popular “Stage 1″ package over to the HR motor with a few minor tweaks.
The Nogaro Red 350Z was brought to us relatively stock, only featuring a Greddy True Dual Ti-C exhaust, which proves to be a perfect companion for any of the twin turbo kits available. The Greddy 20G Tuner twin turbo kit was chosen as the ideal solution for this car’s needs and budget. The setup would be controlled through the Haltech Platinum for 350Z, which can be wired in for cars equipped with the HR engine, and utilizing Deatschwerks 800cc injectors and a Walbro fuel pump to turn this “tuner” kit into a complete package.
Brian Crower rods and CP Pistons were used to help build our Stage 1 shortblock package, as well as new bearings, ARP L19 head studs, and a full gasket kit. Once the fresh engine had been reassembled, the car was ready to be broken in and then begin tuning at low boost. At only 6 psi, running off the wastegate spring, the strong VQ35HR was able to produce 395 whp on our Dyno Dynamics. This was the most amount of power we have seen produced at this pressure.
After a thorough initial tuning session, the car was ready to have the boost turned up a notch. By increasing pressure to approximately 13.5 psi, the car produced a whopping 513 whp before running out of fuel supply. This setup will be limited by the single Walbro pump until a dual pump hanger is installed and tuned for. Our customer will be more than pleased with this power level until deciding to turn the boost up even further for a real monster on the street. Our Stage 1 shortblock package will hold up to far more power than currently being used - perfect for the customer looking to plan for the future while the engine has already been removed.
The stout performance of the VQ35HR platform gives us high hopes for building the VQ37VHR from the 370Z when that time comes. Current owners of the 2007-08 350Z should rest assured that there are equally impressive sources of making big power as compared to earlier 350Z and G35 models.
