I’ve searched threads (here and elsewhere) first, but cannot see where this question has been posted before. I’ve always been a small block chevy guy, and I know them well. My knowledge about the Ecotec is much more limited, but I’m learning as I go. I’ve heard some say that “most Ecotec parts are interchangeable”, while hearing very problematic issues (if not horror stories) from others.
If I go the LSJ route from a Cobalt SS… Can I use an LE5 block (with upgraded forged rods and pistons) AND reuse the LSJ crank (for reluctor wheel and flywheel pattern)? Using everything else from the LSJ (supercharger, heads, accessory drive, etc.)? Essentially, I’m asking if the problematic GenI LSJ block is interchangeable with the much better GENII LE5 block - WHILE USING THE LSJ crankshaft. I’d like the strength and bore size of the LE5, with everything else from the LSJ.
If this IS possible, are the deck heights the same? And can the forged LSJ rods be reused with the LSJ crankshaft (upgrading to forged pistons anyway – if there is an option) in the LE5 block?
Please only respond if you know for sure. Lots of money being spent soon. THANKS!!
