WR35 GTR Performance Parts

WR35TU GTR ENGINE MANAGEMENT TUNING

Having some of the most experienced engine management tuners in the world on staff, Willall Racing are now offering their WR35TU engine tuning program to customers. Working in conjunction with Cobb Tuning, Willall have a range of specifically engineered maps that can be loaded in your Cobb Accessport unlocking the true potential of your GTR.

The Willall Racing WR35TU advantage comes from mapping your GTR for specific modifications and then matching the tune to the quality of the local fuel in your area. This way, with our broad database of test cars we have been able to formulate the perfect map for your conditions.

All of our WR35TU base mapping and development is carried out at Willall Racing using our state of the art Mainline AWD Chassis Dynamometer which offers the very best data logging and analysis bar none. Rapid fire and highly accurate information from the Mainline is one of the important keys to the WR35TU difference.

Power gains from WR35TU are dependent on application, however a stock GTR with nothing else changed can generate over 50hp (37kw) at all four wheels whilst still retaining a conservative and reliable tuning approach that ensures longevity of the engine and drivetrain. Above is an upgrade to a 2008 JDM GTR with Willall midpipe and Cobb Stage 2 97RON tuning. With WR35TU tuning we gained an additional 40hp (30kw) all with only a 1psi increase in boost pressure. Simply fill in the order form and we can email you a WR35TU map for your Cobb Accessport in no more than 48 hours.

WR35FS GTR 1000HP Anti Surge Fuel System

Early in the piece during the hard yards of track development the Willall Engineers discovered a weakness in the R35 GTR fuel system. At lower than 1/2 tank level a series of hard right hand corners could cause fuel starvation, the resulting loss of lap speed but most important a big lean out and detonation in the VR38DETT engine.

Not wanting to endanger their engine, but not wanting to slow the lap time and carry an extra 50lb of fuel load to avoid 'fuel surge' the Willall engineers developed WR35FS, a fuel system that is trunk mounted, quiet in operation, is E85 safe, and has enough fuel flow to support 1000hp worth of power. Plumbing into the standard GTR under-hood mounted fuel fittings WR35FS comes with the following parts -

• WR35FS 1/2 gallon anti-surge tank

• WR35FS 500hp fuel pumps x 2

• WR35FS Wiring Loom including relays and wiring diagram

• WR35FS Braided Teflon hose and industrial crimped JIC fittings

• WR35FS Anti abrasion wrap and cable ties

Installed in the trunk of the GTR WR35FS now allows full power race track laps at less than a gallon fuel level in the main tank, and it does this quietly, without any odour, or without having to carry excess weight.

* Note: Testing has shown that at the local Willall Racing test track that the difference in running WR35FS at low fuel level or running the stock fuel setup with 1/2 a tank is around 0.2 - 0.3 second saving to WR35FS in a 1 minute 15 second lap time.

WR35SL GTR SHIFT LIGHT

One thing that had been missing from the Willall development GTR was a dedicated high intensity shift light. Long we had been looking at the Motec driven light in the GOTO/COBB Tuning track GTR and wishing we had something similar....and now after some testing and researching we do, in the shape of this suberb shift light setup which we have seamlessly integrated to the R35 GTR.

Placed on top of the steering wheel surround the curved base of the programmable shift light sits nice and square being perfectly matched to the GTR interior. Its actually quite stealthy when its off....meet the activation rev point though and the seven leds start to light up across the display before they flash in unison 200rpm before the rev cut (thats where we have it set anyway)

High intensity and highly visible there is no mistaking this unit when it starts flashing at you. The shift light (WR35SL) is full programmable for start point (rpm) and finish point (rpm) inside which the seven leds activate at perfectly matched intervals. There also several different display modes from flashing shift, through to 'from the outer in' and even a battery volt indicator that lights up the leds corresponding to your battery volts at ignition on.

Comes complete with wiring instructions
