. Both F10A and F10D shares the same stroke length; but interchangeability of parts between these two engines is limited, and in some cases unknown, with current findings listed below: Likeness: F10A/F10D transmission bellhousing bolt patterns and diameters are the same, and it is possible to swap transmissions between A and D engines. F10A/F10D both have the same engine mounting points threaded into the side of the engine block. F10A/F10D have identical oil filter mounting points, the extended oil filter housing from the D can be fitted to the A, or the oil filter spigot from the A fitted to the D Differences: F10A intake and exhaust manifolds will not fit the F10D engine (or vice versa) due to difference in the cylinder head bolt patterns and port spacing.

This "low friction engine" as it was called has a revised engine block, lighter crank and revised oil pump. The head is much longer than the F10A version, with a three inch overhang over the gearbox, due to a sensor on the end of the camshaft in place of a traditional distributor, and with a cast aluminium coolant outlet bolted onto the block, consisting of a thermostat, protruding even further. The FWD F10D sump is different shape and length, the block has differing bolt hole arrangement.
