The main reason why ls/vtec isn't that great is because the block has a 1.54:1 R/S ratio...

Rod length: 137mm
Stroke: 89mm

137/89 = 1.54

Now, how in god's green earth can that number be made higher? De stroking it would totaly take away from the idea of ls/vtec (at that point it would be cheaper/less time and labor consuming to get GSR motor). So, i guess increasing the rod length, but wouldn't that make for a large increase in compression?

im stuck... someone give me a good rod length that will yield a not so deadly compression ratio (less than 12:1) or just something that can be run on 91 octane.
