For $100 more you can get 50# flow matched. Does flow match make a big differance in a car with stock motor and lots of bolt-ons
Sampo said:Hi there!
I have those injectors and I bought them there. But I haven't installed them yet because I think I will need the fuel pressure regulator...
I finally changed my clutch yesterday and installed the short throw shifter. Wow! What a difference!!!
Supercharger is also waiting installing while I have so busy on work... How's your project?

Bigger injectors are usually have their flow rated at 43psi. That's above the stock FPR fuel pressure. They will work with the stock regulator, though idle quality can be an issue and they won't achieve their max flow with the stock regulator.

50's probably wouldn't be to bad. I'll be using 60's and will be upgrading the fuel system and adding a remote adjustable fuel pressure regulator so I can get decent idle plus max fuel flow.
So no, you don't need a new fpr unless yours is failing. A shockingly rare failure on our cars.
