68Datsun510 Posted April 16, 2011 Report Share Posted April 16, 2011 Hey folks, using a Z22 H/G on a big bore L18. Timing cover gasket area has already been modded to not leak. But, as some know, the Z22 and L engines dont have the same coolant ports and oil drain holes. Should every single coolant hole be drilled to match the L head and block? Thanks! Quote Link to comment
wayno Posted April 16, 2011 Report Share Posted April 16, 2011 Don't they sell a oversized L block head gasket for just this reason, I read on here somewhere that one was available. Quote Link to comment
Skib Posted April 16, 2011 Report Share Posted April 16, 2011 Im gonna end up needing an over bore L18 HG too, anyone know who carrys them? Quote Link to comment
john510 Posted April 16, 2011 Report Share Posted April 16, 2011 My L20b has .040 over size L-18 pistons and i used a felpro headgasket.How much oversize are you going ? the felpro sealing rings were still outside of the cylinder. Quote Link to comment
dvboth Posted April 16, 2011 Report Share Posted April 16, 2011 I don't know if it would be to big for the L-18 but I am using a NISMO HG #11044-A7651 for my LZ22 build? Quote Link to comment
68Datsun510 Posted April 16, 2011 Author Report Share Posted April 16, 2011 Z22E pistons in an L18 block, its bored .080 over. Its a Nissan OEM gasket. The overbore L gasket is like a $90 piece... Quote Link to comment
68Datsun510 Posted April 16, 2011 Author Report Share Posted April 16, 2011 correction Z22S piston, but same 87mm bore Quote Link to comment
datzenmike Posted April 16, 2011 Report Share Posted April 16, 2011 Not all holes are used even in the L gasket I think, so lay an L gasket over a Z and copy it. Don't just make holes for every hole in the block and head. Quote Link to comment
datzenmike Posted April 16, 2011 Report Share Posted April 16, 2011 correction Z22S piston, but same 87mm bore L18 block bored to 87mm, L16 rods, Z22S pistons??? nice! Quote Link to comment
