There was a good 4 page article on buying & modifying these engines in TKC magazine Nov/Dec 2020.
This issue also included adverts from Burton offering tuning parts for these & other Ford engines and Power Torque who had for sale new Mexican 2.5 litre engines.
Yesterday I found the magazine in my letterbox. After paying 13,-EUR incl. shipping (to Germany) and a three week of waiting it wasn‘t that what I think about. The article is more about the DURATEC engines. The good thing: when I understand right - yes our engine is a MAZDA, the DURATEC and the GDI. And when I understand also right: the GDI is an unboosted (no turbo) ecoboost and an evolution to the DURATEC.
In the Magazin there also a lot of ideas to more power. But for the usual use (and usual filled pockets) nothing real news things.
Have flash, may be a cam… and you get up to 180bhp. The usual area for a flash and the manifold (and cat and exhaust).
