i ran over a 100 bottles through my 96GSR and still had an almost perfect leakdown test, then it go tturbo'd. turbo is what killed it. as for the internals, they were all stock. there are plenty of DOHCs out there running 75+ shots on thier cars, but it isnt used everyday. i only spray my car like once a month. i keep a 5 gallon can of 100 no lead, and just mix in a gallon or so, to keep the fuel nice. i still have the stock FPR. for some reason though, dry kits on hondas dont like to be pushed above 75hp. everyone i have seen do that has either chipped a valve or burned a few up.
