Straydog954 Posted March 12 Share Posted March 12 Which is a better engine? An AMI-370 with the modifications done to it (manifold,turbo, injectors, 5” exh.) or a stock 04 epa MP7? Application would be on/off road dump truck. Would mpg be roughly the same ? Why do the older e7 engines get better mpg compared to one of these two engines?

fjh Posted March 12 Share Posted March 12 AMI-370 with the modifications done to it (manifold,turbo, injectors, 5” exh. In my opinion! How ever the MP engine is OK but more complicated ! Emissions is what kills most new engines due to the complexity ! AI engines a for the most part straight forward ! The Ai engine you quote the emissions have been some what defeated ! 1 Quote Link to comment Share on other sites More sharing options...
