For firing order, look in the manual under valve clearance maintenance, the valve sequence and thus firing order is 1-2-4-3. In the original RX1 Manual that is page 2-10, and it is the same page on the following Apex manuals as well. This is why a bump in HP is realized when changing the exhaust headers to a 1-4, 2-3 configuration.
