SR20 FPR and KA24 FPR differences?

[kazuo]

They different? Or the same?

Any difference in the o-rings for them? Mine (a SR20 FPR) is torn up so I'm trying to get another one for it. Just want to make sure they're not different.

Thanks

Nismo FPR fits both models, so I'd imagine they're close enough to swap the o-ring.

Thank you Russy. :D

I ended up using the ka fpr too when my sr's took a crap.

FYI - the KA fpr is a set rate fpr, meaning that no matter what rpm/boost its always at a certain psi. the fpr on a SR is a rising rate fuel pressure regulator(rrfpr) what this means is for every pound of boost the fpr goes up one psi. Also the sr rrfpr is set at a 1:1 ratio(up 1 psi for every psi of boost). keep that in mind, when tuning a turbo car a rrfpr should be used.

SO basically we should use like, a Z32 TT regulator?
