1380cc race engine build

One of the engines we’ve been working on this winter is this 1380cc race engine build for an MG Midget. Last season the owners previous engine failed, somewhat catastrophically. With a new block sourced we built up a new motor using some of their existing components including their already race modified cylinder head.

We carried out the offset boring to 1380cc at our in-house machine shop, Southern Rebore Services. Piston are light weight slipper type and the con rods are billet steel. The rotating assembly was fully balanced prior to assembly. Next, we installed a Swiftune camshaft and vernier timing gear. The cylinder head was rebuilt and fitted along with a set of 1.5:1 roller tip rockers. Once this 1380cc race engine is installed we will get the car on the rolling road.
