Hay guys I have a GQ with a TB45 with a garret turbo attached to it and it goes GREAT but the compression from the standard motor is to high and it is starting to ping , due to the standard compression it was tune with a max of 9 psi but i would like to sneak a little more out of it . I have had the fuel rail and injectors modified and 4.2 rods put in for added strength , I have to remove the head due to an oil leak from the front of the head and block and am thinking to reduce the compression at the same time , what would be the best way to do this : thicker head gasket , some head work , or maybe different pistons .Where and who could I talk to about this , I am from Adelaide
