Hello, yes it's all about acceleration not top speed !
If the taxes was not so huge in Tintin's country I had buy a 3,7 Roadster, it's only 7 k€ more (which is less that the local taxes needed to put it on the road only for the first year..).
Of course the ECU for a normal Duratec will never work with a direct injection but there are ECU for direct injection and twin variable camshaft timing like the Delta GDI one
https://www.scs-delta.co.uk/ford-ecoboost-ecu 195 HP from a standard 2.0 l Ford GDI (ti-vct).
The open question is what about the CANBUS that (may?) give the info for the various gauges and dials, the immobilizer and the wiring... In one sentence: how build the wiring interconnection between the legacy ECU connectors and the new one, especially if your house is at 500 km oversea from the new ECU provider ...
No local voluntary ? 😉
Maybe at the end if I want more power without more taxes it will be smarter to sell my Plus4 GDI and find a SuperSport toy, one of the 60 build in 2011 with the OMEX engine and 200 HP... and LHD if it exist 🤔
