Hi mate, the kinugawa turbos are fairly decent quality, perform well and last a while. There is only one issue with them and that is internal gate models more often than not have boost control problems as the internal gate isn't really big enough on a td06 sized turbo. I had a td06sl2-20g on a sr20, i ported the int. gate and it was ok but still had some boost spike. After around 6 months of use and track work, the gate got all sticky and would jam up. I had to lubricate it and work it loose every couple of months. My advice to you after my experience would be to not buy one unless going external gate.
