What fuel pressure regulator should I go with?

[got_psi?]

Looking to get an adjustable fpr. I have a black top sr in a s14 all stock, no upgrades (for now). Open to suggestions, something that works well now and will work well when it comes time to do major upgrades...Thanks.

We've got the ISIS FPR kit in stock - I'll be running the universal one on my 1jz project and will be writing a full review of it. It's similar in every way to an Aeromotive at a cheaper price.

But I've heard that the stock fpr tends to have too much pressure when a aftermarket fuel pump (walboro 255 lpr) is being used. Any truth to that?

or when the vacuum line sees boost, i think i may be having this stock fpr issue with my ka as its a bit rich when in boost. Im not sure if the sr has a vacuum line on the fpr but this is something ive read for ka-ts

On my sr it went up to around 40 psi with the walbro 255, If every thing is stock there is no need for the regulator at the moment so I would save the money. change the pump when going to bigger injectors, and change to top feeds if changing injectors. Areomotive makes a nice regulator, make sure you buy a 1:1, and not a FMU.
