Thought to share some experience and mods for this car.
I like extra performance but I also want a good mileage in normal driving conditions.
My best highway mileage at the moment is 39.20 MPG 6L/100km. Driving wasnīt very economical, but anyway itīs the starting point.
The engine has a custom built turbo GT22/23 hybrid, injectors are from the newer D5 engine, with better spray pattern, the ecu has a custom software and because of boost pressure of 1,7bar (24,65psi) the MAP-sensor has been changed to a better one.
So it has performance and the mileage improvements are coming next. Partly they do go hand in hand though.
I guess the testing and building will take time, but weīll see how much progress I can make.
The next mod is to change the rear muffler and go to a dyno and see what is under the bonnet. And Iīm planning some aeromods too.
Latest mpg 29,04 - city driving with heavy foot.
