The one year only 1976 Porsche 912E was an original application for a very specific variant of the Type 4 engine. This recently completed 2.3L RAT version of the 912E engine produces up to 100HP over the factory power output of the 912E engine. More impressively, this is accomplished with only a 15% increase in displacement over the stock 2.0L engine. The added power transforms the 912E into a better driving, more responsive, and powerful daily driver that handles better, and is lighter than a comparable 911.
