O.S.SPEED B21 TY2 Buggy Race Engine with T2090SC Exhaust Combo Set

A new engine project has been launched for the 2014-2015 world champion Ty Tessmann to reclaim the champ. Based on the B2101, a specially designed heat sink head with improved cooling effect in accordance with his driving style and a 5.8mm reducer with improved fuel efficiency that determines the outcome of the race are newly adopted. In response to his request, the combo set with exhaust parts uses a newly designed 90mm long manifold that contributes to stable idling and low fuel consumption.
