It's interesting the OP asked about the 2.3L Mustang, and most people have supplied misinformation about the engine, or entirely irrelevant, or second hand information, in reply. I was the one who called MY engine, a 2.3L, which has blown up twice in 96,000 miles, an "eco-boom".
Is a 2.3 the same as a 2.7? NO, it is not.
Does the GM tech work on Ford 2.3 engines? Probably not.
Are turbo charged semis considered performance vehicles in the same way Mustangs are? No.
Is a 7.3 the same as a 2.3? No.
Do you know anything about the 2.3L Mustang engine? Probably not.
It would be great if folks could stay on the subject of this post. High mileage 2.3L Mustangs.
PS the larger eco boosts MAY use both port and direct injection systems, but the 2.3L ecoboost uses only Direct Injection. Contrary to what others have said on this forum.
