Colors were regular production colors renamed.
Majority of units were C.O.P.O ordered with engines equipped with forged pistons. Original plan was to turbo on an as ordered basis. Vegas have a non-sleeved silicone impregnated aluminum block. Regular production have cast pistons.
Not all Vega Stingers were form these special orders. Nor were all Yenko turbo Vegas Stingers.
E.P.A. Regulations became prohibitive. Yenko Sports Cars was unable to recieve an exemption for a turbo conversion. Plans were formulated to run a 50,000 mile durability test for the turbo-charged car. However further analysis and interpetation of the rules (example: If a spark plug failed and had to be replaced you were required to start over.)proved this not to be cost effective.
Vega Stingers were sold without turbos. Once sold, the owner could then purchase a turbo kit and install it himself or contract to have it installed thru Yenko Sportscars. At no time could it be officially done by Yenko Chevrolet Inc., $10,000.00 fine per infraction.
Test Mule turbo was a white GT.
I had an orange base price and freight notchback for a while (lightest weight)putting out nine lbs. of boost.
