This is an original design of a billet nozzle kit for the 1500 SX-R. According to Yuusuke Hirasaka founder of Killer Racing in Japan, he has been working on this project for over a year. Initially they calculated the waterflow of each speed level by using a special software and when they came up with the best solution they started testing top speed and acceleration. Both were increased and additionally the handling, the intake and pump efficiency were improved compared to the stock nozzle. The reduction nozzle is adjustable (76-87mm) as well as the steering nozzle (79-91mm). Customer can choose one size of each ring when he places an order. The price of this set up rises up to $2500.00 + shipping. An optional part for auto trim steering nozzle kit will be released very soon. For further information contact Yuusuke Hirasaka on FB.
