Powertune Australia built project R32 GTR
I'd like to share with you fellow enthusiasts my BNR32. The r32 gtr has always appealed to me as a timeless shape, so when a cheap one came up i thought it'd be a good base for a restoration into a clean quick street car. Since Powertune built my r34 gtr with great results, i was more than happy to leave this one in their hands too.
Engine internals were unknown when i bought it but i was told by the previous owner it was built/forged at some stage of its life. The car didn't have an extended sump or upgraded oil pump so i knew once we turned the power up it would be a matter of time before something let go.
The previous setup in the car was a twin high mount Trust td05 turbo kit with a Haltech e11v2 ecu with a single Bosch 044 pump and supporting mods. Power at this stage on 98octane fuel was 320kw/430hp @ wheels which felt very lazy but came on like a hammer.
I decided not long after to ditch the Haltech e11v2 ecu for a newer Haltech Platinum Pro ecu with retune on e85 fuel. This meant i also had to upgrade the fuel system. Bigger injectors and a Powertune twin in-tank setup was installed.
On the first few runs the clutch started slipping on the dyno with more power. At this stage since i upgraded the r34 gtr car with a Holinger sequential and a new Quad plate to suit the bigger spline, i had the standard Getrag 6 speed and Quad plate clutch laying around. A couple of days passed and the r32 was back on the dyno again. The car pulled 380kw / 510hp @ wheels.
I drove it around on this power for awhile and really hated how laggy the car was for the street. I had the opportunity to drive an r33 gtr that Powertune had just completed for another customer and absolutely loved the power band and how the whole car drove. The decision was made to ditch the twins for a moderate single Precision turbo.
Precision Turbo and manifold being installed. At the same time i had some custom fab work done in the bay to make things a little more tidy.
Engine bay complete, I've set it up similar to the r34 gtr. Custom catch can, windscreen washer bottle, power steering tank.
With this current tune the turbo is nearly maxed out. Boost is from 4100 to 8500rpm.
