I'm guessing the blocks are similar or almost the same, but beyond that when you think about cylinder liners, piston/rod, and other stuff the engine becomes drastically different.
Cylinder head is completely different. Even the exhaust manifold flange are different, but it's also interesting to note that the WRX FA20 and FB20 found in the base model Impreza (and other cars) have the same exhaust manifold gasket, whereas the FA20 in the BRZ share the same gasket with the EJ20/25 motors.
I'm going to speculate this mostly has to do with the manifold routing design and weight. |
Interesting. The wife has a crosstrek, and I've been thinking about a set of used JDL headers and a trip to my friends welding shop would be in order. Delicious has a flash and go set for it.
