Who knows anything about the k04 turbo on the the z20let?
I think its the k04-15, but can anyone confirm this?
I seems a popular thing with the audi/vw to upgrade from a k03 to a k04 and I think the TT/later S3 has a K04-23. Also I think the courtney/regal/vmax etc turbo upgrade is just an compressor impeller/case change from the k04-15 to the k04-23.
Is there anyone out there that can confirm this or correct me?
