Looks like the difference on the stage 1 to the stage 1.5 is the intake piping and the use of a motor mount.
I thought that I read that the Rotrex unit is the same for stage 1 and 1.5 .
Not sure where the difference in horse power comes from?
The intercooler piping and intercooler appears to be the same.
I don't know if there is a difference in the fuel pump or the injectors.?
