Ok, you definetly need the walbro.

If you go with bigger injectors, you're going to need at least an sfmu to control them.
The bad news, you're probably gonna spend around $400 on an sfmu and fuel lines and fittings, the good news is you don't need an SAFC. The other bad news is, you can't go bigger than 440's/450's without an SAFC, and you may still need it for 440's/450's, however, if you go for 330's or 310's you will not need an safc and will be fine with just an sfmu. Some people have been able to get their car to run right with 440's or 450 dsm injectors (with a resistor pack) without an safc, but others have not, just something to consider when you make your decision
