I know I replied in your other post, but I'll try to get a little more information from you and help as much as I can.
What exactly are you trying to accomplish? If the end result is more power, you could have the blower race prepped, stripped and add a mechanical injection system pushing alcohol for the same money you spend on the EFI. The price of going EFI will climb quite a bit if you decide methanol is your fuel of choice due to the injector quantity and size.
If street drivability is your primary concern, I am not to fond of Carabine ECU for overall tunability. The Fast XFI is the much better choice in that area. The tune that Hilborn will put in will be close, but it will still need tuning.
If it's strictly a race vehicle that sees occasional street duty then mechanical injection will get the job done, but if it's the other way around EFI would be the better route.
Carbs on top of a blower will yield close to if not equal to the same amount of power as injection. Of course methanol will make more power than gas.
