Aloha from an SMD crew member. I will be posting a few more pictures but the first few can be found at <A target="_blank" HREF=http://home.pacbell.net/tak-bsc/SMD_Motorsports.html>http://home.pacbell.net/tak-bsc/SMD_Motorsports.html</A>.
I also have some great "after" pictures from the Protruck's wild ride. E-mail me directly if you want to see them.
It is a single turbo diesel. It runs as a stock-full for SCORE. Since it is a standard motor, it is legal. It produces monster torque but still has enough top-end to pull people on the lake beds when geared for it.
By the way, not only is it SCORE and BITD legal, but for the TT 250 at least it was STREET legal. It was running the factory emissions/chip.
