My mates GTR racecar was a ex N1 racecar in Japan and has the N1 ducting to intercooler and netting to protect intercooler from rocks (rocks can put a hole in intercooler).
I would suggest taking out aircon core infront of radiator when fitting a thicker bigger radiator to allow more air to reach radiator. Radiator size / amount of cores is based on hp engine produces (some tuners in Japan mention this info or can be found via searching if you know this information exist's), so size it correctly.
I would suggest using a Tabata radiator, as have data to back up that the radiator works -
and
Also they look good when installed on a R32GTR -
Engine oilcooler size works off a similar hp formula and have to take into account oilpump pressure, so be aware of this. Size oilcooler core to hp engine is going to produce, oilpump pressure and run a thermostat in sandwich plate. Alot of people undersize engine oilcooler cores. I would suggest using Setrab (used by Ferrari, etc) oilcooler cores, as they have reinforcing on end tanks to reduce twisting of cores during hard cornering. Twisting could make oilcooler core leak at endtanks.
Change all fluids before and after trackday. Don't skimp in this area.
For HICAS delete, Driftworks HICAS delete arms are better due to removing ball joints on rack, hub side which makes it easier to service (don't need to remove hub, etc to change ball joint on hub side) -
