Willall Racing are stepping into interesting territory with the release of their latest upgrades for the Nissan GT-R. So far Willall have been focused on lubricating and cooling the GT-R to prevent untimely wear where possible. This time the goal is much more focused on producing power.

At the core, the upgrade consists of larger compressor wheels, 6mm larger to be precise, and larger turbines, 9mm bigger there. Whenever you hear “bigger” with a set of turbos you automatically think of lag and the big “Will these be laggier than standard?”. To answer that, Willall will also be replacing the standard plain bearing core with a full ball bearing item for overall similar low end power delivery.

Willall’s turbo upgrades are inspired by those Nissan made to the GT-R for the SpecV and they say that power output with a set of these fitted could be increased as much as 100awhp. We’ll know more data after they’ve compiled their data.

Right now these are still in the testing phase but pricing and availability details will be posted when we know.

Increasing the GT-R’s horsepower should be considered carefully because once you get hooked on the power you’re going to start wanting to strengthen the drivetrain to ensure reliability. Willall have you covered for cooling and lubrication but other weakpoints are being handled as well. The WR35CC GR6 Gear Fastener set is a set of three replacement clips for those that Willall have seen failing on GT-R transmissions.

According to Willall, the factory circlip, which essentially holds the transfer gear secure on the shaft is of questionable suitability for the task. So they drew on their motorsports experience to improve on it.

While the replacement does require remove and refit of the gearbox, it makes sense for anyone replacing their gearset or performing any other extensive gearbox work to do “while they’re there”.

Priced at $370 it may very well be cheap insurance against a terminal failure.

After just completing the engineering and testing phase of the new AAM 800hp turbo upgrades for the Nissan GT-R the guys have announced they made 659 hp at the wheels on just 19psi of boost on pump gas! Youch that’s a lot of power. What’s more is that the guys had only just begun to scratch the surface of the potential here and are expecting 700awhp by the time they’re done.

Fitted to the first AAM 800hp Turbo Upgrade Nissan GT-R was the following supporting modifications:

• AAM Competition I/C Pipe Kit w SSQV
• AAM Competition V.2 Intake Kit
• AAM Competition W/G Actuators
• AAM Competition GT800-R Bolt-On Turbocharger Upgrades
• AAM Competition FPR Gauge Adapter
• AAM Competition Oil Cooler Kit
• AAM Competition Exhaust
• AAM Competition 3″ Catted Downpipes
• AAM Competition 3″ Resonated Mid-Pipe
• HKS EVC
• HKS Spark Plugs
• Denso 800cc Injectors
• COBB AP – Custom AAM Tune

Note that AAM actually opted to go for high-flow catalytic converters instead of a straight through exhaust like many would. Interesting choice and it shows their cat’s design is solid for sure.

Next up from AAM is a competition intercooler setup as the stockers just aren’t cutting it at 700hp and I’m not surprised!

There’s already a variety of turbo downpipes on the market but move over and find room for one more. This one stands out of the crowd though since it’s the new AMS cast downpipes. We’ve been following AMS’s progress on these and are pleased to see how they finally turned out.

Featuring cast end sections with stainless centers AMS say these are good for a huge increase in power (20hp peak, 25hp mid-range) and response when combined with the AMS turbo upgrades. They should do great things for stock turbo’d GT-Rs as well.

Check out the dyno graph in the gallery below showing power and torque on the same graph. The red line is AMS turbos with stock downpipes while the blue line is with the AMS cast downpipes. Quite a startling result.

Proving that it’s not only the Japanese that can put together a complete turbo and manifold upgrade for the Nissan GT-R, John Hennessey has released the following preview video on Youtube. It shows the Hennessey Nissan GT-R with a fairly decent sized pair of GT30R strapped to the side in a high mount configuration. Also as you can see, to match the turbos they’ve fabricated a custom stainless manifold, custom stainless dump pipes and fitted up a pair of external wastegates.

The high mount location means they can fit up some nice short intakes which should lend themselves naturally to higher performance. Each GT30R can flow enough air for 500hp so, with two of them, look out because we could soon be knocking on the door of four digit hp Nissan GT-Rs.
