Top Racing HK: Willall Turbos Good for 700ps in Top Racing R35 GT-R

October 20, 2009 Comments off

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 The standard plain bearing core has also been replaced by a complete ball bearing core to prevent any lost in low end response.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 Transmission Piston Seal Upgrades for Nissan GT-R

willall-wr35ps-002

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 Release Turbo Upgrades and Beefed Up Gearbox Parts

August 9, 2009 Comments off

wr35tt3

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.

We saw the design and CAD images back in early June but now Willall Racing has completed the design and fabrication and has installed the WR35OP on their own Nissan GT-R.

The final product is finished beautifully and is supplied with oil pan, oil pickup extension and all seals and quality fasteners required to complete the install job.

Once fitted up, Willall Racing filled up with just under 8 litres of engine oil, a 40% increase in oil volume over standard.

You can order these from Willall Racing or Forged Performance, the US distributor of Willall Racing products.

Willall Racing High Volume Oil Pan for Nissan GT-R

June 5, 2009 Comments off

wr35op-001

The VR38 is a well designed engine but as with any high powered turbocharged engine design it runs hot and puts a lot of pressure on the engine oil to perform. The standard GT-R’s oil volume however may be considered lacking by some for the extreme rigors involved in motorsports.

Willall Racing have developed an extended oil pan for the VR38 to increase the total oil capacity of the engine. Bumping up the capacity from 5.5 litres to around 7.1 litres. The extra oil capacity helps keeps temperatures down and improve oil longevity.

The WR35OP, as it is called, is made from CNC billeted aluminium and bolts on in place of the OE item. The lower section is removable and finned to increase the surface area for extra cooling.

Production of the first units has begun and these should be available soon if everything goes as planned. We’ll keep you updated.

Willall Racing Release Front Mount Transmission Cooler

May 1, 2009 Comments off

willall-wr35tc-f-002

With so many exhaust options on the market today, it can be difficult to find the right mounting for a big radiator at the rear of the car. Unless you go to a loud / race straight through design or a single sided exhaust you may run into clearance issues with a standard Willall Racing Transmission Cooler.

Willall Racing have done their homework here though and come through with a solid solution. A front mounted cooler for those who cant or don’t want to rear mount the radiator.

Utilising the regular WR35TC transmission sump extension, extended lines, updated radiator type and a modification to the GT-Rs front bumper this kit can be fitted to any Nissan GT-R. Front bar removal is not necessary and can be done with it in place on the hoist.

Available now from Willall Racing and their distributors.

Willall Racing WR35TC Transmission Sump Cooler

We were able to give you guys a heads up on the new Willall Racing WR35TC GR6 Transmission Intercooler back in February but now it’s out on sale with data to back it up. One important item we had not mentioned about the WR35TC until now is that it features a coolant pump of it’s own so it does not suffer from the oil pressure issues some other transmission coolers do when relying on the standard oil pump alone.

Willall have taken their own GT-R to the track and put the cooler through a grueling set of hot laps to test it out. On the same day they measured temperatures on the car with the cooler off. Here are the results of the testing:

Lap # WR35TC ON WR35TC OFF WR35TC ON then OFF
1 215°F 220°F 231°F (OFF)
2 226°F 231°F 240°F (OFF)
3 237°F 248°F 252°F (OFF)
4 240°F 265°F 264°F (OFF)
5 242°F 272°F 261°F (ON)
6 241°F 255°F (ON)
7 252°F (ON)
8 250°F (ON)
9 249°F (ON)

The cooler comes in a kit with everything you need include:

  • Billet Aluminium CNC sump with Willall Racing Transfer
  • Bar and Plate 450mm x 100mm x 75mm cooler core custom end tanks with -6 fittings
  • Braided lines and -6 / JIC high pressure fittings (around 4 feet)
  • Mounting bracket CNC machined from billet aluminium
  • GR6 Cooler transfer Pump assy
  • Wiring harness (front to rear of vehicle from the battery)
  • WR series 200F Temperature switch
  • Replacement fill plug CNC machined
  • Magnet mounts CNC machined with captive O-rings
  • Silicone hose – custom crimp fittings CNC machined
  • P rubber lined Mounting Clamps x 5
  • Intercooler Mounting bracket
  • Mounting bolts x 4
  • Instruction Manual

As mentioned, the WR35TC is available now. You can pick up the whole kit shipped to your door for $2995 USD while the transmission sump cooler alone is just $1300 USD delivered. When fitted up you can hardly tell it’s there from behind (see photos below) but you’ll sure be glad it is next time you hit the track.

For those in the US, Marietta, GA based Forged Performance has just entered an alliance with Willall to distribute their products in the US so get in touch with the guys there for help with this.
