don't know about that. my integra GSR has 124k and has the original clutch and has been autox'd since 65k miles. plus 89 civic si's dyno more hp now than they did new. most honda motors don't hit there peak break in until after 100k miles, as long as they are treated proper and given proper service intervals. type r's on the other hand have had a tendancy to burn lots of oil once they hit aroud 40 to 50k miles requiring new rings and seals. most of that however is from jackasses not breaking them in right or putting in synthetic oil before the break in period is over.
