been phoning about getting prices of piston rings for my RST. now 2 of the motor factors told me, that AE piston rings will not be suitable for modded turbos, they can only handle standard boost. they said you will need to find uprated piston rings.

thats news to me

now im at the stage where im beleaving Burton as they know there stuff, but would like some input from so people please on experiance

cheers
