That is Vince Tiagas Mazda3 NHRA car. It pushin like 400hp last time I talked to him..should have a very impressive year this year hopefully. Same engine as the Golden Eagle Mazda6 cept this one is All Motor so no FI.
its not a mazdaspeed 3 but it is a built mazda 3 engine that was at SEMA 2004, i dont think it will be there again this year, new stuff will be coming around (mazdaspeed 6's)
You guys are silly. Thats a full blown, tube chassis, C/F Fiberglassed body Drag car. The only thing that car has in common with any M3 is the style of the body.
