I just bought a 91 na for commuting around when a montyh late the engine blew... I was thinking of an engine swap with a japanese 91 turbo. just curious what else i will need and how much labor should be... i got a qoute on the engine of 1200 and 435 for install from a shop. In addition if anyone knows of a good mechanic to do this swap in San Diego that would be great.... thanks for any forthcoming info
