I don't like high rod ratios. It puts a lot of strain on your rod bearing and can cause failure. When road racing you run into oil starvation (unless your willing to shell out 5K for a dry sump). Your at a much higher risk of failure . I do like2.1L with the 4G64 block, longer rods, and 2.0L crank.

Manley makes a off the shelf piston for it. For rods most people use 150mm (stock) as 156mm dont leave much room for a good ring position. If anyone needs a 94mm crank i have a new spare, fully balanced and blueprinted.

stock RR is 1.70
94mm crank with 150mm rod is 1.59
100mm crank is 1.5

150mm rod with a 94mm stroke will see the oil ring above the pin hole.
156mm rod with a 94mm stroke will see the oil ring into the pin hole, so the rod/pin will have to be installed before the rings.
