Re: 4A-FC with supercharger?

its not *just* a fuel pump upgrade... there is a lot more to it than what you might expect.
You would most likely need to do the following:
- reduce compression ratio
- replace existing carby with something that will match fuel supply to air flow, and re-jet to suit
- work out an air bypass valve for the supercharger
- get mounting bracket for supercharger (or make one)
- fuel pressure regulator
- many other things....
the problem with carby is that there is only ONE setting for air/fuel mixture - and hence even after extensive dyno tuning the car would either run like a pig off boost, or on boost, and *possibly* well the other. Tuning (and fitting) a carby to suit the extra air flow would be expensive.
Fuel pressure regulators arent exactly cheap either.
Dude - big old motors are a different story to your simple 1.6L twincam motor, trust a few people when they suggest that it simply would not be cost effective to do.
Even if you did get it all to work - you would still probably have less gains than installing a 100kW 4A-GE (and at double the cost!!  )
Buying the front cut is ALWAYS the cheaper option in a corolla. NO BUTS!
