No, i aint been racist... but KKK was the manufacture for BLITZ during the golden era of Japanese tuning.
From my understanding KKK are still in business and make a mean turbo. Supplying many main stream car manufactures.
Although blitz never really hit the heights of HKS or GREDDY in terms of turbo popularity, they did give it a red hot go.
Most of the early stuff was non ball bearing, possibly holding them back, but if you ask anyone who has run one of the K27, K3T etc they are by no means boring to drive.
Very comparable to the Greddy range, but with alot better reliablilty
It appears as blitz have made a few small changes recently and still offering the kits new, although im not sure who the manufacture is these days.
