Sirio now offers a new engine mount and exhaust manifold to install the ultra-powerful Sirio .23 engine in the Traxxas Revo. The new mount replaces the center section of the stock 2-piece engine mount, making the installation of the wider .23 engine a bolt-in operation. The exhaust header adapts the big block exhaust port of the Sirio .23 to the stock and most optional tuned pipes. The exhaust manifold also fits standard big-block engines, so it’s going to be available separately for those that want a larger diameter high-performance manifold when using the Traxxas and other big block conversion kits.
