i think its just how hard the engine was drivin. i have a 205k miles LS 90 G2 and it runs VERY strong with NO major problems nor has it had any...besides a clutch at 202k miles (throwout bearing), my dad bought it brand new and only shifted at 3k never passed so i guess that has something to do with it (performance wise, the clutch was me :rick: ). i think all honda engines were built the same, just different engines got different care thus resulting in low performance. i think my teg could put up the same times as a brand new 90 g2 would
