Perrin fuel rails

Has anyone any experience in installing the Perrin fuel rail on the ej22t?
Got some advice from Matt to use the 93-94 NA rails because they can
handle newer injectors. Tech guy at Perrin wasn't sure but asked about
the angle or positioning of the injectors on the ej22t.
Help, or is the Perrin set up needed

I think I can answer your question, but I'm not sure what you're asking.
92-94 NA rails will bolt right up correctly and can accept many upgrade injectors including those used on the late model STi and those specified as upgrades for Nissan SR20DET motors.

I have the rails you need and you can have them for cheaper than the Perrins.

Bigger turbo will need more fuel, this will require bigger injectors.
What will fit best on the ej22t?
Do I mod the stock rails. Do I take these off and put on the NA rails or
will the Perrin fuel rail system fit without either of the above
Perrin guy didn't know

The NA rails simply replace the stock turbo rails. 2 bolts for each one, with some small bolts on the end.
You can get 370 440 550 and 850 cc Nissan injectors that fit.
I am running 370 cc srdet20 injectors myself.
Simply search on ebay.

So are those 550s the STI pinks?

Legacymax-No they're the oem USDM STI side fed yellow top 550cc.
Subtle- Like I said in the PM, I don't think the perrin rails will work because they are for the wrx dohc heads.
Just use the 92-94 NA rails. The EJ18 rails work too.
