At the request of our list member Tom in Poland, I have taken most of the dimensions relevant to selecting a different engine to fit the DeLorean. Especially considering that he smuggled some very hard to get metric measuring tapes to the States for me, it is most fitting that I use them for the job. :) It also helps having a chassis apart to take these measurements without the engine in the way. I welcome any comments from anyone who has an opinion on what will fit and what won't. Walt Tampa, FL Height: Measuring from center of crank (input shaft of transmission): -- 51.6 cm up to lowest point of engine cover at front fire wall (taken from top of ignition resistor bracket). -- 45.5 cm up to lowest point of engine cover at rear fire wall (taken from bottom of rubber tips at rear corners). -- 22.9 cm down to bottom of oil pan -- 15.0 cm down to top of frame cross member (which holds motor mounts). -- 23.0 cm down to bottom of frame cross member (cross member is 8.0 cm thick) -- 20.4 cm up to highest point on frame which is visible from engine compartment. Measuring from highest point on frame which is visible from engine compartment: -- 25.1 cm to lowest point on engine cover (which is the rubber tips at rear corners) Width side to side: -- 79.9 cm is width of frame at transmission/engine interface (narrowest point) -- 91.7 cm is width of frame at rear fire wall (widest point). Note: engine compartment is approximately 8 cm wider on each side than frame. So as long as the engine barely clears the frame, you will have an additional 8 cm on each side to access sides of engine. Length front to rear: Measuring from cross-brace mounting holes (also lines up with rear shock mounting on frame): -- 16.1 cm forward to front fire wall -- 56.5 cm back to rear fire wall -- 1.3 cm forward to transmission/engine interface Measuring from transmission/engine interface: -- 60.4 cm back to rear inside of frame Note: This includes the hollow space between the rear fire wall and the frame. In order to use this space for the engine compartment, part of the rear fire wall will need to be cut away. -- 57.9 cm back to rear fire wall -- 8.8 cm back to rear of frame cross member (which holds motor mounts)
