Well I'm officially done with the conversion/upgrade to the rabbit.
I had taken it to the shop today and had the system evacuated(had 12oz), vacuumed and refilled to 100% capacity(32oz). On the way home I QUICKLY learned that it couldn't handle that! The whole way home my comp cycled on and off and the vent temps were in the mid 60s. When I got home I checked my pressures and idling it was over 300. With a little rev it went over 400 with ease.
Thankfully I installed the cutoff switch ackits sells and it saved my a/c system by shutting it down!
After evacuating an unknown amount I took the pressures down to 225-250 on the high side and saw a minute amount of bubbles in the glass(zero bubbles with 32ozs). I took it for a spin and in 84 degree weather the vent temps got down to 47. That's nearly a 40 degree drop and the wife was very pleased.
Overall I'm very happy with the system and I can't thank ackits.com and this forum for all the incredible help.
An airconditioned hippy,
Jason
