Starters crank an engine over pretty good with the LiFePO4 battery 4 cell configuration with 13.2 volts.
Problem with putting the battery in the trunk is you have longer run of cable and more voltage drop. I put them behind the seat.
For powering the coils I say get a constant voltage booster and turn it up to 14.6V, that is the highest voltage I have seen on a vehicle electrical system.
That way when the engine is cranking and battery voltage is at say 11 volts the starter will see get a constant 14+ volts.
This is my battery build:
