Nissan Skyline GT-R Race Car Maintenance Schedule - R34 N1

R34 Nissan Skyline GT-R Super Taikyu
In the race car world, you can not afford to have a car break down. It costs thousands of dollars, and takes so much time and effort to get to the track, that not replacing items on an aggressive schedule just doesn't make sense.  Most street car people run a car until it breaks. Most will change the oil, maybe some other light maintenance, but not anything like this.

This schedule is for a race car, under race conditions.  Nethertheless it is interesting information. Most GT-R owners probably never think of a transmission overhaul, ATTESA pump, or rear differential overhaul on a schedule. This schedule was originally from Tetsuo Suzuki from Shift Racing. They ran the Falken R34 GT-R in N1, and at the Nurburgring.

Super Taikyu /N1 Schedule Replace/ Rebuild
Engine Overhaul 3000 km ~1800 miles
Power Steering Belts 3000 km ~ 1800 miles
Power-steering pump  6500 km ~4000 miles
Power-steering hose 4000 km ~2500 miles
Engine mount 4000 km ~2500 miles
Transmission mount 4000 km ~2500 miles
Front drive shaft 4000 km ~2500 miles
Front hub 4000 km ~2500 miles
Front Caliper Seal  600 km ~ 400 miles
Transmission overhaul 1000 km ~600 miles
Transfer case Overhaul 13000 km ~8000 miles
Rear Differential 5000 km ~3000 miles
Rear drive shaft 5000 km ~3000 miles
Rear hub 4500 km ~2800 miles
Rear caliper seals 1000 km ~600 miles
ATTESA ETS pump overhaul 1 race
Engine oil 1 race
Front diff fluid 1 race
Transmission fluid 1 race
Rear diff fluid 1 race
Transfer fluid 1 race
Power Steering Fluid 3 races

For a street car this schedule is a little more realistic.

This is a short video edited down to 27 minutes. The engine was in good condition, but I wanted and improve the engine to withstand stress during race track and drag race.
Engine block was drilled up to the new 86,5mm pistons and surface grounded. Cylinder heads were also surface grounded.

Mounted Tomei 1,5mm oil restrictor to decrease the amount of oil to the cylinder head, which again leads to increased amount of oil in the oil sump.
Made an extra oil return from the rear of the cylinder head, with a return hose below oil level in the sump, so that the oil flows faster down to the sump, and cannot be pumped up again (siphon principle).

Mounted new Nismo main and rod bearings that are a little stronger than the original bearings. Oil clearings where all checked to 0,038mm. Thrust bearing clearance checked to less than 0,1mm, more than 0,05mm.

New CP Carrillo 86,5mm forged lightweight pistons and Eagle forged H-beam rods with ARP 2000 rod bolts. Piston rings where filed to the correct gap, according to the sheet that came with the pistons: 1st ring 0,45mm , 2nd ring 0,55mm , oil rings 0,35-0,45mm.
Re-used the Tomei Pon cams, 269 in and 252 ex, both with 8,9mm lift. Valve clearance where checked to 0,4mm in and 0,35 ex.

Re-used the Nismo oil pump. I measured a total clearance to the crankshaft drive of 0,35mm (0,175mm on each side). Hope, and think, this is good enough for this power when keeping the rev limiter to max 8000rpm.
New original NPT water pump.
New ARP studs to keep the cylinder head and gasket tight.
New Tomei metal head gasket with 1,5mm thickness (0,3mm over size) to keep the original compression ratio.
New Tomei intake manifold metal gasket, throttle body metal gaskets and exhaust gaskets.
New Nismo thermostat that opens at 62’C. It’s easier to keep it cold than cooling it down when it’s too hot ;-)
Re-used the Greddy Grex oil cooler and oil cooler sandwich with thermostat.
Re-used the HKS exhaust manifolds, but had to re-weld them because of cracks.
Re-used the HKS 2530 ball bearing turbo’s.
New Gates Racing timing belt, idler and tension wheel. Also see how I centred the CAS and CAS bracket in the "7: Timingbelt" -section. This is important. If not in centre, it could lead to bearing failure in the CAS or even crack.
Filled oil in the oil pick-up to check the oil feed to the bearings, cylinder head and turbo’s.

Oil pan where custom made to increase the oil amount about 1,7 litters, like “wings” on both sides. They do not go all the way down, to make the oil pick-up the lowest place in the sump. Also mounted Nismo baffle plates to keep the oil where the oil pick-up is, to prevent the oil pump sucking air which could lead to catastrophe.
Re-used the OS Giken triple plate clutch and flywheel.
New Nismo engine mounts. 

Re-used Greddy large intercooler and piping, Apexi Power FC ECU, Apexi boost control valve, Greddy / Denso 720cc injectors, 2 x 300ZX Z32 MAFS, Greddy air filters, ground wiring kit and Apexi exhaust system.
