WoodsWagon Posted August 10, 2008 Share Posted August 10, 2008 EA81 has single cam in block with pushrods out to the heads EA82 has single cams in each head with two timing belts. Link to comment Share on other sites More sharing options...
GeneralDisorder Posted August 10, 2008 Share Posted August 10, 2008 There's a lot of small differences, but only one major one. Think of the EA82 as an overhead-cam EA81. The EA82 was developed for the 1985 body style change as an interim solution while the EJ engines were being developed (EJ development began in '85 also). It has a primitive timing belt system vs. the well-developed push-rods of the EA81. They reversed the valves in the heads as well. For all that extra complexity it really isn't much benefit. The highest power EA82's were around 175 HP used for racing. The heads and head gaskets can't hold much beyond that. In contrast there's a company here in the US that sells a modified EA81 rated at 200 HP and it's reliable enough for use in aircraft. GD Link to comment Share on other sites More sharing options...
Phizinza Posted August 11, 2008 Share Posted August 11, 2008 Are we talking differences between the engines or the bodies, or both? Link to comment Share on other sites More sharing options...
