Hello
Currently installing new injectors in the 305 iroc. I pulled the old ones out 523530 which I assume are the original standard ones. When you look inside the nozzle you see a pin whereas others I have seen have a nozzle with small holes to make the spray pattern Is this the way they made them or is something missing.

Thanks

Single hole is the old oem style. Newer injectors have 3-4 holes and better spray pattern.

i need a set for my 90 l98 ---who makes the best injectors now, i've been out of the game for 12 years raising kids but it is time to get the old girl running.

The Delphi units from Southbay work great and are 100% plug and play.

the question is at over double the price of the bosch units are they any better? is there a difference in spray like talked about above with multiple holes vs a single hole in the bottom of the injector?

from what i remember before i parked it i had put in a new fuel pump and a direct wire voltage kit and upped the pressure about 15 lb to help fueling under boost. i know the dealer replaced some injectors as the factory ones had issues with the coils shorting out.

Delphi’s are a more direct replacement for oem multecs. The d3 work great but two downfalls. Noisy and they should be tuned for look at threads for d3 offsets. You have a FMU ?

No fmu, the paxtons in the 90's did not come with them. i remember the dealer replacing some shorted out injectors under warranty and i adjusted the fuel pressure up to around 60 psi and burnt a new prom

i may also have a set of fort 30 lb injectors from a mustang laying around someone told me would fit with tuning...i think the 30's will be too big even if i turn down the fuel pressure so maybe i just should get some new 24's as the injectors in the car are from 1992 and are likely the old style
