what fuel pressure regulator do you guys recommend and is it difficult to install? this is all for a s14 sr20 with 550cc deatschwerks injectors, thanks
Aeromotive, nismo, tomei saard those are all good brands. as far as install goes you need too order a fitting for your fuel rail it’s two bolts that allows you to hook it up you also need the fittings for the fuel pressure reg and some good high quality hose rated for fuel injection it can be nasty if you don’t get pressure rated hose…

and depending on waht fpr you get and what type of fuel hose you want to run you will most likely need two of these http://www.frsport.com/DIF-Fuel-Fitting---8mm--5-16-in--Hose-Barb-Male-to-1-8-NPT-Male_p_54436.html
