GReddy have officially released and priced their latest offering in the cooling arena for the Nissan GT-R, their Spec-R HG T29 Intercooler Kit. The kit comes in two forms, the full kit and the conversion kit and is designed to replace not only your OEM intercoolers with a joined core crossover type intercooler but much of your intake and intercooler piping as well.
The full kit features polished hard piping kit to support Trust pod filters in replacement of the OEM airboxes, polished hard piping kit to replace the intercooler piping, silicon host joiners, GReddy blow off valves and other minor but very important items such as brackets and hoses. The full kit retails at 388,500 yen in Japan.
The conversion kit assumes you already have the Trust intake piping kit so removes the intake pipes and the blow off valves. It saves a little money and goes for around 312,900 yen in Japan.
With either kit, you’re crossing the airflow over so you should need to take into account that the airflow sensed by the left MAF (mass airflow sensor) will now be fed to the ECU to control the RIGHT throttle. So most people recommend extending the MAF wiring harness to correct this when using this type of intercooler. I do not see a mention of that being included in either of these kits so it’s something to be aware of.
