im lookin into droping the portfueler and going standalone MSnS

Im looking @ the kit on symtech labs site, and was wondering a few things:

1.can we use our coolant and air intake temp sensors?

2. my ignition will be controlled by the MS, will i need to run an ignighter from a 4G6x?

3. what else would i need besides the kit? since i have the PF system i already have the return line and 1:1 FPR


I currently have portfueler, and was wondering if there was an injector size calc somewhere, so i can see what i need.my goal is ~400+ i would imagine 72 lb/hr would be ideal but idle may be an issue?

engine: 8.8:1 CR, s20G, 3" full exhaust, 60mm TB etc..
TIA guys
