Top Racing HK: Willall Turbos Good for 700ps in Top Racing R35 GT-R
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 The standard plain bearing core has also been replaced by a complete ball bearing core to prevent any lost in low end response.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.

Willall Racing Release Turbo Upgrades and Beefed Up Gearbox Parts
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.
