He has a JWT Ecu, stock injectors, stock sized turbos, boost controller intake/exhaust and 100 shot of wet nitrous. He just ran a 12.3 on street tires. He's still running rich as well. Blows my mind. He had a different Z 10 years ago with the same set up. Ran it all the time with the nitrous as well and after several years of abuse he blew a piston ring with somewhere around 150k miles. I'm not a fan of nitrous but I'm very intrigued.
