The billet main caps are unnecessary, and only involve alot more machining to be installed on the engine. Save your money and machine the stock main caps. I don't think I have ever heard of the stock 4G63 main caps failing.
If you are going to be running a 6-bolt, I would recommend looking into the Kiggly main girdle for extra support.
If you are running a 7-bolt, then it is only necessary to clearance the stock main girdle to fit the rods (on a 2.0L; but you will need to still clearance the rest of the block to clear the rod stroke; especially if on a 100mm crank).
for a 2.0 7bolt build do you have to grind the bottom of the cylinders to clear aluminum rods? got any pics?
