I am selling my stock K04 Turbo. Never had any issues with (smoking, etc..), selling it because I purchased a PTP SST Turbo. This could be a good purchase for anyone looking to go the same route with a super stock turbo. I will sell mine for $200, normally you get a $300-$500 core credit depending on where you would get your turbo from. Or just use the turbo to make you riding lawn mower go faster! Or I am open to trades ( I am looking for a HKS BOV amongst other things)
