Unless you guys have a different 2.0L over there then most of that your buddy told you is false. The 2.0" and 2.3" use the same engine block so there is no way that the bell housing pattern would be different. There have been several successful 2.0L to 2.5L swap done and its basically the same as swapping from the 2.3L.Hi, Guys,
Very interested in all of this but...
I've have heard that the 2.0 l timing cover will not fit the 2.5 l because the cylinder head is different ( taller). Someone else said that the bell housings are different so that the 2.0 l gearbox doesn't fit the 2.5 l block and that basically the swap is near impossible. This guy who told me all this was working at the wreckers where i went to see about a 2.5 l engine and that he had been involved in a swap. He also said there are problems with ecu's and axles etc, etc .
Generic diagrams of the 3 engines look identical to me and i thought internals were mostly the same for the 3 engines except for the crank stroke to give the extra capacity
Tried looking for pictures of the 3 engines ( 2.0,2.3 and the 2.5 l side by side ) so i can see for myself , but no good . I should mention that i am in Australia so i am only looking at Mazda engines not sure what Aussie ford engines would be compatible with this swap. If all this info is wrong,then would my option to get a oil pan and timing cover from a 2.3 and swap all my bits over to the 2.5 l like you guys describe. Does anyone in the US have pictures of the 2.0 l , 2.3 l and the 2.5 l engines showing the timing covers and oil pans so the differences can be seen? I suspect that these 3 engines are the same or close design for the US , Asia , Europe etc.
My car is a 2008 Bk 2.0 l hatchback and the 2.5 l that I would be interested in swapping is from a model we have here called the Mazda 3 SP 2.5. I thought engines from cars Pre Sky Active would fit up to 2013 .
Nothing wrong with my engine just wanted more power is all.
Happy days ,
