You guys are forgetting that obd1 blocks came with oil squirters. They shoot directly under the pistons and are perfect for turbo apps. Also, all the older 4 bangers (9a, pre 94, PL, PG, etc..) all came with forged cranks rather than cast. That is where the potential hides. As for datalogging with Tec3.... i've never worked with an obd2 ford setup, but the TEC3 unit in my heap doesn't have the best logging. Though, as long as i can see my A/F vs Timing then i'm pretty content with it ... just want more !
