From what I've read about these turbo's they are very similar to the 530BB but cheaper. I can get them for a little bit cheaper than 1200 to my door and HKS actuators for ~150. I don't mind putting in labor hours as i'm trying to save as much $$$ as I now have to do a FULL rebuild. Just $$ alone add up very quickly between EFI, all the machine work, having someone knowledgable do all the 'precise' work.
