Fuel pressure reg
 

Hi everyone I've got a subaru impreza classic 1999 with the 440cc injectors however It doesn't have a fuel pressure regulator , is it advised to get one if so what are some good ones ? And how difficult to fit are they ? Thanks

The two recommended by the mappers I've spoke to are fuel lab and turbo smart. And guess what, they're the most expensive on the market :(

We can supply Torques Uk ones. We use all there fittings for our fuel rails , very high quality and better prices :)

Will I need to remap the car again after fitting on ?

Have you removed the standard fpr?

I haven't done but don't know of it ha been done before I bought car where is it situated. ?

LOL, erm, I don't know where it is, just know that they have one as standard as when I changed fuel pump I asked my mapper as I had upped the LPH and he advised to check the AFR but the standard one would probably be fine running around 300 bhp.

It may be worth me talking to a mapper telling them my mods and seeing what they advise next think I'm running around 270 ish but want more any good mappers in the north west area around Liverpool ?
