Available now from HPI Racing is our Nitro Star S-25 engine! This powerful new engine has 20% more displacement than our Nitro Star 21BB engine!

The Nitro Star S-25 is a .25 cubic inch (4.1cc) big block engine that features a machined billet aluminum heatsink head for extra cooling, dual bushing aluminum connecting rod, true ABC chrome sleeve construction for durability, and a simplified dual needle 7mm slide carburetor for easier tuning with a composite body for better performance at higher temperatures.
