At which point on the bhp do you require to change the factory fuel rails to after market rails? I'm going to be running 500 to 600 bhp and it's a newage STI.

Thanks

Am sure plenty of people using them for upto 450 ish bhp,

If you are having such a high spec build I think parallel fuel distribution is a must. I wouldn't use perrin ones as they are very large and PITA to fit with Sard 800cc injectors which you will probably be using.

If you want anything close to 600 bhp mark then you will also need to run larger flow and return to the tank.

have you even got a spec in mind for this power, seems a very big margin to be working with

aftermarket is a bit of a pain as I tried this with more problems ?? But going parallel fuel rails is a must for you

What kind of parallel fuel rails should i look at?

The ball is on the roll with the built engine with Chy.

What problems did you have with the after market rails?

api supplied the rails for the scoobynet project car. Good quality at a good price!

I was told if you are aiming above 400BHP then yes, many people dont have them I suppose, but its better to be safe than sorry.

I originally tried to fit APS fuel rails but they kept leaking! So the original fuels rails were made to run parallel

Fai17,
At 500-600bhp is it essential you get even pressure/flow to each injector?!
