I am in the process of stroking my motor. I have a 96 Lude with an H22a. I got an H23 crank that is being offset ground from 1.888 to 1.771 (98mm). I will get custom rods and custom pistons. The pistons will be 89mm 1.150 comp. height with .827 b series wrist pin. This will be at 0 deck.

A lot of people are advising against 0 deck. What are your thoughts on this? What can I modify so that I am not at 0 deck? Any help and input is appreciated. (I have not ordered the pistons or rods yet).

 

Good stuff But I suggest you sit it below. Usually I sit them .010 (inch) below the deck. This will account for any strech in the rod. Plus the head gasket. If not begin by claying the engine.

 

If you are running good steel rods and a .030" thick head gasket, zero deck would be good. ** BE sure the head gasket doesn't protrude into the cylinder**. If you get beyond .060 clearance between the piston and head (including the gasket), you loose the benefit of quench. If your running aluminum rods or cheaper steel rods, you may consider opening it up (definetly for aluminum, approx. .060"). If your not deckplating (raising the deck height) make sure the pin doesn't go into the oil ring groove and require buttons or a support. The longer stroke will decrease the R/S ratio and cause the piston to rock more than usual leading to oil consumption. I don't know where you were ordering your pistons and rods through, but if you contact Sean @ ERL Performance, we can spec. pistons and rods to help neutralize this rock.
