This 1970 Porsche 911 “918 RSR/LS3” is one CRAZY Porsche that was at the SEMA 2015 show. First of all it has a LS3 V8 engine swap. Then add to that lots of custom outside modification and paint. The interior is also full modified. Overall the Porsche purist might not like this, but one has to give the builder, The Custom Shop, credit for a intense build.
