Hey,
Today I finally got my GTR tuned with my GTSS turbo's and MINES dump pipe upgrade. MRC in Castle Hill who installed the turbo kit a few months ago did all the tuning work on it.
Just for information value current mods on car is..
GTSS turbo's
Mines dumps
HKS front pipes
Trust PEII cat back
Cam gears
Profec b boost controller
Power fc
Apexi pods
So still standard intercooler, injectors, pump, air flow meters etc.
As the graphs show it made 275kw's at 1.1 bar and pretty good 12:1 air fuel ratios. Boost is very steady after the initial slight spike. Car feels a whole lot better. Only downside is the air flow meters are maxed out, and to be expected the oil temp does creep up quicker and go higher. Nothing that a cooler wont fix. At this stage the fuelling and cooling will probably stay as they are as I dont have the money at the minute to upgrade, but all is very safe none the less. It did make a peak of 294kw's but he pulled some timing out just to be on the safe side.
Overall very happy with the performance and service of Mark at MRC.
NOTE* If anything is thinking of doing GTSS turbo's on their GTR DO IT!! They're awesome street turbo's. And to those with cams aswell even better!
