Dave Zwalinski's 2013 Ben-Sopra GT-R

Dave's second GTR is also TKO's most ambitions project, and quite possibly one of the most unique and capable GTR builds in North America.  The build is still in progress but nearing completion and needless to say Dave is very excited.  His first GTR (AMS built Alpha 9) was just the beginning of Dave's ongoing addiction with acceleration and beatiful body lines.  When BENZILLA is complete it will have north of 1300whp and be capable of 8 second 1/4 miles, all while being one of the only Ben-Sopra wide body GTRs in North America.  Sporting an eye catching vinyl wrap in 3M Gloss Green Envy this car will have no problems living up to it's nickname whether it's showing or going.
