It was standard, a WRX RA with a re chipped ecu, always run on optimax, Had been rolling roaded and showed good power and no faults, 2 weeks after the RR day I was racing a TVR and took it flat out in 5th which I later found out was a big NO NO, Piston 4 ( I think - passenger side rear ) got really hot - its the futhest away from cold air and the furthest from the oil pump? so it got really hot and started melting, it took out the big ends the con rod, piston, 4 valves and the crank. After the re build I never ran it flat out again!! but other than that it was reliable just really expensive f
