FPR on S13 SR, Need help. - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have a basically stock S13 SR that i am cleaning up and getting ready to run, i want to replace my stock FPR but do not know exactly what my options are.

My plan is to purchase a good quality FPR and set it to the stock Fuel pressure. The reason i want to replace it is because i have a Walbro fuel pump and i know that it over-powers the stock FPR a bit.

So my question is what is the technical info on the stock FPR? Is it a 1:1 ratio? Or is it a rising rate FPR? I believe it is a 1:1 but i just want to be sure.

I would really like to go with a SARD FPR, but i cannot find technical info on it which makes me nervous. I need to know for a fact that their FPR is a direct bolt on replacement for the SR.

What is your experience with whichever FPR you have?

Here is a picture of my build in progress. Just for fun.
