I just bought a set of GSR PISTON, And I notice that the rings need to be replace... Anyone knows wher to get new GSR piston ring... Or anyone knows if the GSR piston rings is same as the 4G93 rings...
when dis happens my rev feels like a pull back, drop of performance for 1 sec,,,, on dyno machine at each run, it always happens at dat region, thus im not able to pull above dat region, as da a/f ratio fluctuates up...
