Rochester, MSD, Precision injectors etc, all the same.

 

There rochester 38lb injectors... All four of them...

 

i got those injectors and i dont know how to put them on my b18a1 motor can any one help the hook ups r different!! anyone help me pls!!!

 

Those look like dsm injectors out of a gst/gsx eclipse which would be. 440cc

 

Nope, not DSM injectors.


I have a set of precision 400's on a customer car that are identical.

I would search the part number.

 

Those are Delphi Injectors, (which Precision uses) and have varying flow rates depending upon part number. If you're not sure, send them to a facility to be flow tested
