Mine only has 68.000 Km on the clock. The engine in mine has allreday the upgraded banjos, because it is a late 2002 modell. I have contacted Honda Germany after i bought mine, and they have confirmed it according to the chassis and engine Number.
The problems with the banjo bolts only get severe here in Germany, to my knowledge. Only in germany some early S2000 engines get damaged after long high speed runs on the autobahn.
Honda get aware of the Problem, the Banjos get updated on all S2000 from the first half of 2002 on, and in Germany all S2000 get a recall and the Banjo Bolt upgraded free of cost from Honda. Some Owners say that the recall also was done in the rest of Europe, but i dont know for sure.
Driving this car on the Autoban feels a littel bit crazy, because at "Crusing Speed" of 100 Mph / 160 Km/h the engine revs allready with aproximately 6.000 RPM in 6. gear.
This feels really insane in a car and is a little bit demanding for the engine. But this car was not built for this, it is meant for lonesome, windy country roads. I dont use this car often on the Autobahn.
