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 ?
