Willall Racing Release GR6 Clutch Retaining Clips

October 12, 2009 Comments off


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.

Willall Racing Transmission Piston Seal Upgrades for Nissan GT-R

September 30, 2009 Comments off


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


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.

SouthSide Performance Solid Transmission Mounts for Nissan GT-R

July 1, 2009 Comments off


The Nissan GT-R is a potent supercar for sure, but there are some notable tweaks that could be made that some people think may elevate its status again to ultimate motorsports weapon. One motorsport in particular that’s cause for concern is drag racing since the high torque loads that this sport subjects the GT-R’s transmission to are known to cause a component or two to come under some unusual stresses.

That’s the sort of thing that the guys at SSP have been thinking of for quite some time now and to that end, they’ve designed and machined these solid transmission mounts to assist coping with the loads the GT-R’s tranny sees. These are said to go some way

These solid trans mounts are CNC machined from solid aluminum and designed to be direct fit replacements for the OE rubber and liquid filled items. These mounts are available in two packages, a stage one including four mounts that remounts the transmission alone on solid mounts and stage two, a further four mounts, that replaced the upper liquid filled transmission mounts as well. There’s eight mounts in the total package.

This modification isn’t for everyone and it may not be suitable for your daily driven street car. You’ll see (well hear really) an increase in noise and vibration in the rear as everything is now solidly linked together. For those guys tracking the car more regularly they’re worth considering.

Transmission Adjustment for Everyone via Carman SCAN Tool

June 7, 2009 Comments off


Nextech’s Carman SCAN OBD-II scan tool has supported the Nissan GT-R for about a year now and has been used by many that don’t have access to or can’t afford the official Nissan Consult III hardware. It can read and diagnose GT-R error codes and clear them as well.

Recently Nextech have released an update that should allow Carman Scan tool owners to adjust GT-R TCM settings themselves, saving a trip to the dealership. The GT-R’s 6 speed dual clutch transmission, the GR6, has 4 settings for the automated clutches. These settings are regularly adjusted during service time to keep it performing at it’s peak. Adjusted incorrectly however and driveability and clutch heat problems issues can crop up.

On top of this the new update allows the modification of the ABS settings to tune braking performance and ABS sensitivity.

The Carman SCAN tool is still not cheap at around $4,000 for the unit but it’s an option for some and both Sunline Racing and MCR in Japan have added it to their tool kits.

Willall Racing Release Front Mount Transmission Cooler

May 1, 2009 Comments off


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.

SouthSide Performance Transmission Cooler for Nissan GT-R

April 2, 2009 Comments off


SouthSide Performance have now backed up their previous transmission strengthening clutch upgrades with a new transmission cooler codenamed the GR6-TC230RS.

It may appear cryptic to you but when you consider that the SSP transmission cooler’s aim is to keep your transmission fluid around the 230 degree F region then it all begins to make sense.

This transmission cooler comes with an extended sump billeted from 6160 aluminum. The sump is is also finned to increase the surface area and thus offer cooling properties by itself. That’s not all though, the transmission fluid is pumped by a high volume pump through a bar and plate cooler. Two electric fans assist air moving through the cooler to assist when outside airflow is minimal.

Priced at $3,199 the SSP transmission cooler should be available around the end of April 2009. The full press release can be read after the jump…

SouthSide Performance Upgrades for Nissan GT-R Clutch Packs

March 29, 2009 Comments off


It’s been a long product development cycle for SouthSide Performance on these. We originally got word that they were developing them back in October 2008. They’ve made it happen though and today they’ve announced the results of their efforts.

Two different clutch pack products are going on sale, from SSP the first of the two is the SS Clutch Pack. These are the first aftermarket OEM style clutch replacement solution for Nissan GT-R owners. Right now even Nissan will not replace a clutch on the GT-Rs sophisticated GR6 dual-clutch transmission so this is a godsend for anyone who’s modified their car and worn the clutches already. The SS Clutch Pack comes with 12 friction discs that are direct replacements for your factory items.

The second clutch pack is the RS Clutch pack. These have a larger (25% larger) friction surface area in order to handle the big power some of these modified GT-Rs are beginning to make. We’re told these RS Clutch Packs are perfect for those seeking up to 700 hp at the wheels.

Installation is relatively easy, something that can be undertaken at any competent transmission workshop. This is really good news for those who may not have too many R35 experienced techs in their neighborhood.

Price for the SS Clutch Pack is $1,399 with the RS Clutch Pack coming in at $1,599. Both should be ready to ship to customers at the end of April. For more information on ordering them, we urge you to go direct to SouthSide Performance at the link below.
