I just recently purchased a used S trim Vortech Supecharger with 4,000 miles on the supercharger, i own a 91'LX, the engine is stock except bored over .030 , my question is what injectors should I go with on a stock motor? I am thinkin about 24ib injectors.. but with a supercharger producing up to 20 pounds of boost should i go with 30ib or 24ib

u should go up to 42lb injector

the guy i got it off of was runnin 24 ib injectors in his mustang.. he had a 351 windsor.. he said that 24ib was fine for him... i forgot to add i was only producing 8-10 psi with the stock pulley

36, 42, 50 In the big boost range.
It might be a good idea to get a KB boost-a-pump too.

id be careful using 20 lbs of boost on stock iinternals.... Go with at least 30's

42s with no FMU. If the guy you got it from was using 24s, he was also using an FMU.

agree.
stock efi 351 comes with 24# injectors.
