I did know about the existence of turbo-ed 2T and 3T engines, but bi-turbo?

If you look well enough you can see a big intercooler behind the cutted front air dam. Also where the grille used to be an oil cooler has been placed. It is unknown which engine has been used for the swap, but it is surely a bi-turbo diesel engine. (probably a 2L-T hilux diesel engine)

The original car appears to be a TA60 Carina coupe and its 31 years old Finish owner takes really good care of it:

Yep, that’s how easy it is to get a Carina sideways when you have loooooads of torque! I wonder how long it will take before D1GP will be flooded with diesel engines. :D :D

This is the most recent video of the car:

I wonder if there will be more updates soon! :)
