Hey everyone! New to the forum seems like a really helpful place. My Gen1 has 6G72 3.0, and it's toast. What engines bolt up to the auto transmission? Diamante 3.0 DOHC? I'm fine with the power I get out of the SOHC but I can get the DOHC for pretty cheap. What engines bolt up? Will I need a donor wiring harness and ECU?
