The stock connecting rods in the CA18 can handle a lot more than 400hp, provided they are in good shape. If I remember correctly, Garage Paddy made something like 700whp on stock rods in their silvia. Dee makes upwards of 500whp on some of his engines (heck, its probably something like 30 of them. Guy has a bit of a CA18 habit) on stock rods, no problem.
If you want to upgrade anything on the rods, just get ARP bolts for them. Its a good investment, as they won't stretch at high-rpm like the stock rod bolts will. Spend the rest of your money on getting a good tune.
E: please note, CA18 stock rods are already forged.
