Ive been after a recon'd K04 for ages now as mine has up/down play and very small in/out play. so with not much luck in sourcing one i might have to go down the rebuild route. Im wondering how difficult it is to actually do it yourself and is it cost effective? Turbo Dynamics have quoted me £300 to do the job. Also I dont know if its a good idea to buy a new hybrid turbo or not, would i need forged internals for this? therefore making the job massive and cost alot! more.
