My approach EV Conversion

It is my first convertible, my first MGB and is gonna be my first EV.. I enjoy driving my MGB and want to know her better - how she drives, handles the corners, on the freeway. 
I wanted really know how she behaved before the conversion. Someone in one of the forums mentioned that MGB need to be really on the road and needs to be taken care, unlike other cas and MGBs have soul (sounds funny?); and I wanted to really know the soul. I want to see if the soul exist after the removing the Internal Combustion Engine (ICE), tranny, radiator, etc..


I wanted to drive my MGB on ICE, while I convert to electric. I wanted to slowly remove the dependency on ICE -

• the hydraulic brakes need vacuum to to apply the brakes. ICE feeds vacuum to Hydraulic Brakes and this is my first step for the conversion..
• ICE will be replaced by AC50 Hi Performance motor. I would mount the motor, test it; then switch it back to ICE
• Heater circulates the hot water from ICE and fan blows hot air through the vents. I would convert this to use Ceramic heater. 
• Finally I would add Battery, charger and BMS (Battery Management System). After I test the Battery and BMS, I'll do the complete switch-over to Electric

Of course this is the plan and will see how it works out.
