S13 & S14 SR20 need help
 

If anyone has either or both of these applications, can you please help out with injector spacing measurements? Basically i need to verify the following center to center of each injector measurements. Doesnt have to be exact close enough will do. Thanks!


INJ 1 to INJ 2 -

INJ 2 to INJ 3 -

INJ 3 to INJ 4-

The measurements should be identical between runners. I measured 3.8125in between all of them.

As far as I know s13/s14 are the same, just the mounting tabs are different between the rails.

Technically speaking, they should all be the same, whether its a DE/DET/VE/GTIR etc. They all have the same bore centerlines. I think the biggest factor would be where the injectors are plumbed in on the manifold. The only place I have seen for any SR variant is at the head flange.
