I'm a bit of a noob when it comes to technical stuff but here's what happened:
Engine/Car: RB26DETT / R32 GTR (1990)
Type of failure: Spun oil drive collar on crankshaft = no oil pressure @ 8000rpm, saw the light and backed off and shut the car down. Crankshaft snout, oil pump and harmonic balancer stuffed. Everything else was just really old and dirty.
Factors influencing the failure: Age and design flaw of the R32 GTR Crank??? Oil flow issues???
State of tune of the engine: Stock - Cat back exhaust, Intake
Suspension and tyres: Nismo shocks and dampers, 18x9.5" work emotion cr kai (265/35), Falken
Oil used and service interval: Oil + Filter + Maintenance every 5000km
General comments: Wasn't happy at all when it happened - especially the financial side. Decided upon ground up rebuild with lots of new parts (pistons, rods, 33 crank, n1 pump, turbos, valves etc etc)... car is a neat streeter, no high power figures here. Figured on not changing the original recipe of the standard gtr too much - after all it lasted 20 years before catastrophic failure right?
