I went to rebuild my 86 and found it was already bored 40 over. I picked up a core out of a 2wd 92'. This block is actually really nice with original toyota pistons. I'm building for reliability on the trail. Everything was working good on my old motor, just rattled and lots of blow by. I'm planning on only using the block and picking up a new head, and bolting on my 86 intake stuff.
Found a crack in my exhaust manifold. Can the 92 exhaust manifold be drilled and tapped to accept the O2 sensor?
Is there anything else on the 92 I should reuse that works better than the 86?
