I'll be upgrading to a bigger turbo soon and was looking at the Power Enterprise 650cc injectors as a replacement for my current STi injectors.

Who here uses the 650's and with what fuel rail?

I have a set of MRT fuel rails (not installed yet) but have recently heard negative things about them. Because of this I'm looking again at the Perrin fuel rails. Before I make the switch (and I'm not sure if I will) I want to see if anyone has tried the pe650's with an aftermarket fuel rails system.

Can anyone help me out?

 

I have held both rails in my hand. I prefer the Perrins. The MRT uses a huge end fitting with a large Oring. My thought is that this O ring will leak one day... Could be 5 years down the road.. Then what? Also, The Barb fitting in my opinion is way to small. It looks around 1/4 inch. I also do not like the idea of running dual stock FPRs. The WRC car does this and it works but I would always wonder if both sides of the motor had the exact same fuel pressure.

East Coast Scooby just installed the Perrin rails with SS lines and AN fittings into an SX regulator and Canton Meca Fuel filter. He uses the PE 650s and they work great. Email him or PM him for more info.

Thanks man, I'll talk with him about it.

I have also heard that the O-ring was rather big, lending itself to leakage. Fuel leakage is baaaad!

 

The body is much larger. In fact you do not run the large rubber bumper/Oring in the TGV housing that seals the tip of the injector. With the PE units the seal is made high up the body with a seperate Oring. The concern is not fuel leakage its an intake leak at the tip of the injector. ECS's seem fine...
