I FILLED the glove box with time slips with a X police car 91 coupe bone stock with street tires. Best I got was a 13.9@101...A bone stock TTZ runs about the same. Friend has a 91 bone stock on street tires and with his Z, he got a 14.0@100. So they are about the SAME! So, if you have a bone stock non turbo Z that beats these cars, you have the fastest stock NA in the world.
