But, most stick with the 13B-RE and convert to a single turbo.

About 1% say F-it and go for some version of the Chevy smallblock, because it's easier to build (and heavier overall, short of the modern aluminum blocks& heads.)

As for the SR20DET conversion... I can probably still count the number of people that did that in the US on two hands. It's just stupid to do in an FD body.
