-You don't need an MSD ignition, stock one will be fine and OEM units have been known to be adequate up to 400hp
-You don't need an AEM fuel rail, fuel delivery won't change much if you swap the stock one out, we're talking just a foot of overbored fuel line then it tapers back to the stock diameter
-I assume at this point you're going to use some type of rising rate regulator to supply the extra fuel since there's no plug n' play unit for your car, unless you want to shell out the big bucks for a DFI, Haltech, blah blah blah. If so, that Walbro will be strained at the high psi the rising rate regulator will demand. I suggest you go with something external.
