6220 - Full Mod CNC Track Ported Zenoah 22.5cc Yuji Edition On-Road Engine

This engine is sent out with a standard Zenoah crankcase unless you request our billet case. Reason being our billet case does not fit most on-road cars and this engine is designed for competition on-road use. 

Every long block or engine is now CNC ported and hand finished. CNC porting and hand finishing is all done in-house by the OBR staff. We do not contract out any of our porting so every engine is modified to our exact specifications. We are able to offer higher accuracy this way as well as more power. Our CNC machine has allowed us to take our porting to the next level due to us being able to do cylinder work that is not possible to do by hand.

This is a brand new fully modified track ported Yuji Edition Zenoah G240RC engine. This engine is built specifically for 1/5 scale on road racing and will run a full race on one tank of gas. The Yuji Edition G240RC is built to be very smooth and high reving for track use. This engine fits: Contrast, FG, RS5, Harm, etc. This engine comes with a standard Zenoah crankcase unless billet is requested. Our billet case does not fit some on-road cars. Contact us if you are not sure which crankcase will be compatible with your car.
