Have some parts arriving for my Sti v3. Spec is to be:

Using Walbro/550 cc injectors and will have a TD05 hybrid/Apexi FC. Gruppe S headers and 3'' decat.

Need a fuel regulator to suit, preferably adjustable, but need help on what else, ie rising rate or what!

Can someone guide me to Spec and supply source? The fuel rails are phase one if that makes any difference.

I have a similar spec (different ECU and injectors though) and am using a FSE FPR.
They cost just under £100 and are available from AS Performance.
Some people complain that over time, their fuel pressure drops, and/or you need to 'prime' the system twice before starting the engine - but i haven't had any problems with mine.
I have left the gauge permenantly attached so that the pressure can easily be checked
If money is not an issue, you could get the SX one
You definately want a 1:1 reg. NOT a rising rate one...Apparently they make mapping a bit difficult.

FSE would be your cheapest option and what I run.. the only complaint it is doesn't seem to hold the pressure when engine off but with short pipework it seems to work perfectly and even with long pipework I just had to prime the pump two on the rare occasion it didn't up the pressure enough.
Or the SX which is rising rate is very good.

FSE would be sufficent.. SX if you have the money.. imho..

Mark @ www.lateralperformance.co.uk can supply either and a fitting kit to connect straight to the fuel rail where the old reg comes out of etc..

 

Thanks to all. Have tried to email Mark before but zero response. Will try again.
