quick question that a search did not resolve...

does anyone know if there is a difference between the FPR's on a 94-95 gsr and a 92-93 LS? reasong being, I have a gsr fuel rail and pressure regulator that looks nicer than my LS one, and it positions the FPR further right.

there is a smaller outlet tube on the gsr one, btw.

any help would be great, thanks!

 

anyone have fuel pressure numbers for a gsr vs ls?

 

bump

 

I'm about to put it all together, I want to use the gsr fuel rail, would prefer not switching fpr's unless they have different pressures. anyone?

 

use the one designed for the ECU you are running, the fuel maps are calculated based on the correct fuel pressure.

 

okay, but are they actually different fuel pressures?

 

i could look up the specs, but im too lazy, and its only 2 bolts.

 

specs call for :
ls: 39.8 -46.9
gsr: 47.6- 54.7

so they could be around the same or not. just try it

thanks for doing the hard work, in that case, if you use the GSR regulator you will be rich for sure, not much, but worth noting.

edit cuz i realize you arent putting it on a GSR. oops.

thank you very much!!!!

they are pretty close, but I think I'll play it safe and stick with the ls fpr unless I need more pressure
