Type of Car: 1993 R33 GTS25T - RB25DET
Type of failure: Damaged Rings on #3 and #6, Valves on 4 and 5, rooted turbo...
Factors influencing the failure: uhhhh few things. Was running a jap tuned Mines ECU, warmish weather 16psi through stock turbo, accidently left oil cap off(idiot), and was flooring it off the toll booth through the M2 trying to race a porche, while the car was pinging off its head...
State of tune of the engine: Front mount, Mines ECU (now gone), exhaust, oil cooler
Suspension and tyres: Whitline coilovers, 225/40R18 front, 25540R18 rear, front and rear torsion bars
Oil used and service interval: 10w 50 every 5000ks
General comments: after all that, am now alot more carefull with my car, don't boost past 12psi, and only in cool weather, and have ditched that dodgy mines ecu... even on stock boost it would occasionally audibly ping. Never get a mines ecu. Ended up fitting a new motor and turbo, now car is as good as gold:)
