SPE News - SPE Projects: And so SPE Godzilla was born - Nissan R35 GT-R

When Godzilla emerged from the sea and terrorized the streets of Japan, people fled in a frenzy of terror. Here at SP we would like to think that the unveiling of our SPE Godzilla Package will do the same to anything on the road it crosses paths with.

Throughout the past few years of R&D, as well as installing our packages on multiple cars, we have learned a great deal about the GTR and we decided it was time to create a package that could reach even greater goals than our 1000R Package.

Meet our SPE Godzilla Package, capable of producing a monstrous 1800+ Crank Horsepower on E98 fuel.

The build starts with our SPE Spec 4.0 liter race motor which is built from the ground up with:

- SPE Spec Full Blue Print and Balanced Short Block
– SPE Spec Steel Sleeves
– SPE Spec H Beam Connecting Rods
– SPE Spec Custom Forged Pistons
– SPE Spec Head & Main Stud Kit
– SPE Spec Stage 3 Camshafts
– SPE Spec Stage 3 Race Head

As well as beefing up the motor’s internals, the GR6 transmission is upgraded in house with a stronger gear and clutch system to accommodate the massive power increase.

The entirety of the modifications to the GR6 Transmission include:

- PPG 1st to 6th Gear Set
– PPG Billet Output Shaft
– Dodson Promax Alloy Clutch Kit
– FWD Retainer
– Oil Pump Upgrade
– Magnet Kit
– Mechanical Circlip 1 & 2
– O-ring and Seal Kit
– Transmission Filter
– Piston Selector Shims x3
– High Temp. Rear Differential Seal
– Heavy Duty Clutch Return Spring Seals x2
– Heavy Duty Clutch Return Spring Retaining Clips
– Piston Shaft Seals
– FWD Output Seal
– 2,4,6 Thrust Bearing Clip

While the internals of the motor/transmission are a key ingredient to handling the power, the external components of the motor are a key ingredient to adding all that power.

Such as our SPE Spec Throttle Body combined with the SPE Spec Greddy Intake Manifold.

The SPE Spec Greddy Intake Manifold holds an additional custom tapped fuel rail to provide the amount of fuel needed for all the power: specifically 3000cc in each cylinder. This is vital as being tuned on Ethanol requires an average of 30% more fuel than regular gasoline.

A great deal of custom work goes into the Godzilla package, such as our SPE Spec Custom Manifolds built in shop.

Each custom piece is manufactured to the utmost precision to provide consistency in any build. Our SPE Spec Titek Solid Motor Mounts is another prime example of this.

Our absolute pride and joy however, is our SPE Spec Titek 102MM Titanium Full Exhaust, which is included in the Godzilla Package. It weighs in at 27.9 lbs, roughly 30 lbs lighter than the OEM exhaust.

Every aspect of the exhaust is titanium, and it flows as follows: (2)80MM piping -> v-band -> (1)102MM piping -> v-band -> (2)80MM piping -> v-band -> (4) 80MM tips. The 102MM aids greatly in avoiding back pressure and is a critical component to this build creating so much power.

Once all the custom work is done and ensured to meet our standards, the external parts of this motor’s build are properly installed. These items include:

- SPE GODZILLA Turbo System
– SPE Spec Custom Manifolds
– SPE Spec V-Band Turbochargers
– SPE Spec V-Band External Wastegates
– SPE 76mm Down Pipes
– SPE Spec ETS Race Intercooler System
– SPE Spec Greddy Aluminum Intercooler Pipe Kit
– SPE Spec Greddy Blow Off Valve System
– SPE Spec Air Suction Pipe Kit 90mm
– SPE Spec Greddy Fuel Rail
– SPE Spec Intake Manifold
– SPE Spec Additional Fuel Rail
– SPE Spec 75mm Throttle Body
– SPE Spec 3000cc Injectors
– SPE Spec AAM Fuel Pump System
– SPE Spec Race Fuel Pressure Regulator + Gauge
– SPE Spec Oil Catch Tank
– SPE Spec Titanium 4” Exhaust System
– SPE Spec Racing Spark Plugs Range 9
– ATI Crank Damper

All this added power creates some seriously high temperature numbers for the motor and transmission, so our SPE Spec ETS Race Intercooler System is installed (Godzilla Art not included) to provide even greater cooling.

A Greddy DCT Cooler for the transmission is included as well, which allows for optimal hydraulic pressure and maintains extremely consistent temperatures not effected by coolant temperatures.

After everything is installed and the cooling is taken care of, the vehicle is brought around to the dyno and the most vital part of any build begins.  Our SPE engine calibration is achieved with Syvec’s S8 (SGTR) which allows for absolute engine management control.

This leads to the photo most important to any build, the claim to fame. That is of course, the dyno graph. For those wondering, that right there is 1.0 BAR beginning at 4500RPM, 3.0 BAR (Full Boost) beginning at 5800RPM leading to a consistent 3.0 BAR from 5800RPM to 8000RPM. This in turn, produces the numbers of a max torque at 1197 and a max power at 1405 to the wheels, power even Godzilla himself would be intimidated by.

Side by side comparisons are crucial to measuring improvements, so the photo above presents our Godzilla Package on the same graph table as one of our customer’s SPE1000R Package. The SPE1000R package produced a max torque of 976 and a max power of 1185.

To add even more assurance of how powerful our Godzilla Package is, here is a Record Table of what the SPE1000R was capable of achieving in the 1/4 mile. A consistent 8.8 second (roughly) 1/4 Mile with a consistent 165 mph (roughly). Here’s a video of the 1000R’s fastest pass:

Here at SP we are as anxious as you are to see what 1/4 mile times the Godzilla Package will be able to produce. We are doing some final testing and ensuring the tune is dialed to maximum efficiency. So stay tuned for those numbers (as well as increased power/torque numbers). They will be here soon..

Thanks for looking.
