breaffyaviation Posted August 30, 2005 Share Posted August 30, 2005 How can you tell if an ea 81 longblock motor was a turbo or not if everything is stripped off it? Did any of the carbed engines come with turbo? Thanks in advance. Jude Link to comment Share on other sites More sharing options...
fat Posted August 30, 2005 Share Posted August 30, 2005 breaffyaviation Did any of the carbed engines come with turbo? No none of the Turbo car's were carbed. If it was turbo it was MPFI. ~FAT~ Link to comment Share on other sites More sharing options...
Turbone Posted August 30, 2005 Share Posted August 30, 2005 The EA81T pistons are cupped or dished for lower compression. Also, the fuel injectors are in the heads above each sparkplug. Link to comment Share on other sites More sharing options...
Ross Posted August 30, 2005 Share Posted August 30, 2005 There is also a tapped blind hole on the top of the block where the knock sensor goes on the turbo motor. Link to comment Share on other sites More sharing options...
NorthWet Posted August 30, 2005 Share Posted August 30, 2005 The injector bosses and dual intake ports should give it away. Link to comment Share on other sites More sharing options...
Ross Posted August 30, 2005 Share Posted August 30, 2005 Only single intake port on the ea81t. Link to comment Share on other sites More sharing options...
