Modification of an eligible MA4-5 carburetor is required for use with the 0-470-50 engine. Overhaul of the carburetor at the time of modification is recommended unless it has been recently overhauled, or is in excellent condition.
Eligible MA4-5 Part Numbers are: 10-3965-12-1, 10-4893-1, 10-5192 or 10-5284. With authorization from NorthPoint, the carburetor modification (an overhaul as well) may be accomplished by AvStar Fuel Systems in Florida, Professional Aircraft Accessories in Ohio, or LyCon Rebuilding in California.
Whether converting a Continental 470 or 520 to the NorthPoint XP470 Engine, the end product is essentially the same – a carbureted Continental 0-520 which rated 265-275 HP.
A precision balanced engine offers several advantages, including significantly improved performance, smoother operation, less maintenance, and a longer TBO. A smooth running engine also reduces pilot fatigue and increases passenger comfort.
Engine prices are not addressed here as we do not control pricing or warranty of the shops we have authorized to perform the engine conversion. There are many parts and accessory options available including a choice of cylinders that affect pricing, so please contact us or one of our authorized engine builders to discuss your specific needs.
