One issue with the 12V Busso engine is the lack of wrap on the left hand bank pulley. On high performance engines this can cause belt jump on start up and occasionally on overrun. By fitting the later round tooth belt and pulleys, it increases the tooth depth and by adding our belt guide you can have peace of mind that valves aren’t going to hit pistons .
Kit has all 4 pulleys, belt and belt guide.
Available for both 3.0 and 2.5
