I have two timing questions
Firsy one is, isn't it possible to have timing 180 out? Not 180 out like the dow pins are at 12 oclock and the notch on the dampner is opposite of the T on the timing cover. I mean the number one cylinder is at TDC on the exhaust stroke instead of the compression stroke? All the valves are closed at TDC on the exhaust stroke just like the compression stroke correct? And if this is possible, will the car still start at all?
Now for my "second" question. I have a 91 gvr4. I am runnimg an evo 8 ecu. The firing order is completely opposite of a stock 1g ignition timing. So again leads back to my first question. If in fact it is possible to set mechanical timing 180 off, and I do in fact set the timing CORRECTLY FOR A STOCK 1G ECU it wouldn't be correct for the evo 8 ecu that has the opposite firing order? So I would need to set the mechanical timing with the number four cylinder at TDC on the compression stroke instead of number one?
