hey guys,,,, can someone tell me what the bottom of a stock 8.1 injector looks like? does it have 4 holes, or just 2 big holes? I bought some 8.1 injectors and i think the guy gave me the wrong ones.

 

You are going to have to look up the part number on the side. Take a look at them, and post the number up here.

 

Who did you buy them from?

 

25323974

 

25323974

 

thats the part number, and i think its made by delphi

 

some one told me that the stock 8.1 injectors have 2 holes,, my rc 42#hr have 3 holes, and the mysterious injectors i got now have 4 holes in the bottom, i wonder if they are even higher flowrating than the rc's?

 

i bought them from "ranwalk"

 

I'm pretty sure the stock 8.1s flow about 30#s. The Marine version of those 8.1 injectors are the 42 pounders that RC and ASM are selling. I haven't heard of any Multec II injector with a higher flow rate.

 

My 99 injectors look exactly the same as your 25323974 injectors, 4 small holes. My guess is they're going to be 21 or 24 lb'rs.
