Radio control Nitro engine Sirio .27 Pro

Sirio .27 pro

I bought this engine as a replacement for my nitro truck and it never happened.

This engine has vicious amounts of power all the specs are below. Standard engine mount size fits most buggies and monster trucks. Has collected a bit of dust from doing nothing.

Still need to be run in. I bought this engine for a R3000.00

This engine is considered the upgrade engine for the 3.3 revo for more power and speed.

I am selling this engine as is.
