I just dismantled a customers kinugawa VF40 16g replacement. The turbo failed due to debris in the the oil system. Not the turbo or manufacturing fault.... the quality actually surprised me! High grade O ring seals for the compressor housing, very large diameter turbine shaft, thick brass journal bearings, oil slinger, and very good looking machine work. I can post pics for you guys tomorrow if you want. I really dont think there is anything bad about these turbos! Hell the quality looks way better than any VF IHI turbo Ive ever taken apart!
They look great and have VERY HIGH reputation in the UK and Japanese market. Just google them, browse www.scoobynet.com
they love these turbos and many are sold used with 30k-40k miles! Blouch wont even help you if the turbo blows up the in the first damn day! (true story).
