• Material: Composite Kevlar carbon high friction
• Drive Coeff: up to 33% improvement with 0.125 friction index
• Surface Area: up to 16% improvement in clutch face surface area vs factory
• Temperature handling: Increase maximum clutch temperature point 400F versus 350F factory
• Bonding: Double bonded up to 600F resistant, chemical resistant
• Stiffness: Heat treated high strength steel construction at 68 Rockwell

The Willall Racing WR35TT twin turbo upgrade package was announced earlier in the year and has been finding it’s way into a few GT-R builds. The premise is simple, take the superb standard combined turbocharger exhaust manifold setup and improve on it.

The improvements specifically consist of a 6mm larger compressor wheels, and 9mm larger turbine. The standard plain bearing core has also been replaced by a complete ball bearing core to prevent any lost in low end response.

One of the biggest concerns for anyone installing bigger turbos is the affect it has on the low end response, by inducing turbo lag. After installing and testing the Willall items however, there appears to be no appreciable effect on the GTR’s low end output at all, seemingly matching the OEM turbo response.

Being the sole distributor for all Willall Racing products in Hong Kong, Top Racing was delighted to be the first to install and test out these set of turbos. The Top Racing GTR demo car was able to produce over 700hps @ 1.4bar boost with supporting modifications including the COBB AccessPort and 800cc Deatschwerks injectors.

The Willall Turbos make strong power with a significant gains throughout the rev range. The fact that this upgrade maintains standard low end response mean they’re great for daily driving while delivering real punch when you want do some hard driving.

More transmission part replacements/upgrades from Willall Racing have been released recently. Known as the WR35CCL, these items replace the stock clips that keep the clutches on the main shaft. While I don’t pretend to know why Nissan went with such a weedy looking retaining clip (left) from the factory it’s evident that once you remove these you probably don’t want to put them back in and rely on them to keep your $26,000 transmission functional.

If you’re fixing or upgrading clutches, piston seals or anything internal to the trans, maybe consider an upgrade like this to do while you’re there. You’ll be replacing these clips anyway so why not go for a more substantial hardened steel version. The price is set at $150.

The GT-R has quickly grown from supercar to super tuner base car and it seems to be getting trickier to find an owner who hasn’t modified their GT-R these days. Just an exhaust they say, or just an ECU reflash… It’s so simple and rewarding, so why not eh?

While the debate on the durability of the Nissan GT-R’s gearbox may still rave on various blogs and forums around the net ,the innovators amongst us are coming out with their own preventative measures to prevent problems before the occur in a catastrophic way for those who do get the urge to tune.

One of the newer products on the market is the Willall Racing GR6 Piston Seal upgrade. Designed to prevent failures caused by OE seals that may deteriorate and cause the transmission to fail into limp mode or, at worst, take other internals down with it.

Priced at $390, you can hit up the Willall Racing website linked below for the full rundown and order form.

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.
