re-ringing boosted gsr
hey H-T
recently finished building a gsr for boost, got it broke in and then boosted. ran flawless for the first 3 months but today had my #4 cylinder rings collapse on me. So now i have a dead cylinder pumping nothing but oil so i am going to tear it down and re-ring the bad cylinder. my only question is should i re-ring ALL the cylinders or just the one that went bad? i dont really want to have to take out all the pistons unless i have to and the other three are a consistent 150psi across the board. also i used rock rings with this setup... not too pleased with the result on this one. should use them again or any other suggestions? thanks for the input.

Re: re-ringing boosted gsr
Since you most likely broke the ring lands you are probably looking at having to hone the cylinder.
You can do that in the car, but if there are deep scratches then you are looking at having to bore.
Either way, you are going to have the engine torn down extrememly far just ot get at that one piston.
You can just work that one cylinder alone, but -
I would hope you would want to pull all the pistons and go with something that will last longer than 3 months.

Re: re-ringing boosted gsr
before the compression went completely bad it was at 90psi. 100 is minumum for cumbustion. now im assuming its waaay lower than that. i have all the equipment to do the honing and whatnot and i am hoping the cylinder walls arent scored or marked up. i will probably end up re-ringing them all but just wanted some opinions
