A12T is the twin carb engine fitted to Datsun Sunny B210 and Nissan Cherry PE10. It uses the Hitachi Twin Carb system, dual 38mm Hitachi sidedrafts. These mainly differ from the A12GX Engine Hitachis in that they are fume-controlled with closed vent system for EVAPO. They can be easily distinguished by their flat tops.

Overview

JDM 1973-1975 B210 GX models had either an A12S (single-carb) or optional A12T (twin-carb) engine. While the A12T is very similar to the A12 GX Engine, it used different flattop Hitachis and a slightly different intake manifold with a few more fittings. These are good carburetors that are not jetted leaner, but instead have a closed fuel bowl vent system.

JDM Datsun Cherry (E10) models also used the A12T engine, including the famous Cherry X1-R vehicle.

Datsun Competition (Nissan Competition) sold a open-vented system:
