A 255 lhp hp pump will support enough fuel for 400hp+, but youll need an aftermarket fpr. Your gonna run rich with a 255lph with a stock fpr, and fuel cut can be easily avoided with larger injectors/Afc or getting your ecu chipped. If you dont plan on going for 400hp+ then I say get the 190lph

i'm getting it for cheap that's why but do you think it will be ok for my car if it has less than 350hp what's the difference between this one and the high pressure one

 

[SlowSpyder]

you can still use the 255lph for your car, its that if you get the 255lph then plan on spending some money on an aftermaket fuel pressure regulator. The 190 lph will flow 190 liter per hour but this will not overrun your stock fpr. The 255lph will definitely overrun your fpr and your injectors causing you to run rich

Like these guys said, unless you wanna spend the extra money...then don't get this "for cheap" fuel pump. Because, if you do you're gonna need the adjustable fpr. And I found something else: . , "" ; : () ! ? I think it's all the punctuation from your posts. Please use them, we'll all love you for it.

And why is this different in 1Gs?

Why no need for an AFPR w/a 255 fp on a 1g? Or is there?

Newbie to mods here.

Some people run poorly with them, some people run decent enough that they don't
need an AFPR but they really should get one anyways.

so a 190 will be ok with hp around 375?

 

[kooka]

a 190 will handle over 400hp no problem.

99% of the people with 255's will never have a setup for them.

 

[4geze63]

I have around 300hp now, at what hp level would an FPR be needed, after I got injectors?

 

[Steeezin]

ones power level doesnt determine if you need a fpr or not, rather what your base fuel pressure is after installation.

 

[4geze63]

so at what point will it be nessesary to get an fpr with a 190
