Fuel rails for EJ20G + 550's?

[James614]

I feel silly asking this. All I can find is you need N/A rails, but the info about what engines to take hem from I can find is for the 22T. It makes sense that EJ25D rails should work since the 20G and 25D are practically 100% interchangeable, but figured I'd ask to make sure.

I will probably get the 550 (w/ launch control, which i opted out of the first time around) tune going soon here and my trans/clutch are REALLY gonna hate me.

Ej25d rails are what you need.

Brat man is right, because the SOHC fuel rails don't fit the DOHC hardlines.

That's great to hear, there's two in the local yard here.

Okay, got the rails and injectors today. But now I can't seem to find the post that had the part #s needed for the o-rings, particularly those bottom seals on the rails.

16608AA020 big one at the bottom

16699AA000 fuel rail to fpr

16607AA040 insulator for injector cap

16698AA060 & 16698AA050 are the injector body o-rings (for ej25d yours may be different

17595AA000 o-ring for rail to fuel lines

Well thanks a lot Bratman! That's a huge help.

Just hit up an autoparts store for gas resistant o-rings. Costs a couple bucks versus a couple hundred from the dealer.

The large insulator at the bottom are 3.68 each online, and the top insulator are 6.02 plus shipping, unless your dealer will match online pricing. Mine won't because it's ran by monkeys. Those are probably the only ones that will be hard to find aftermarket.

I wound up getting the main body O-rings from DW, as they are less than 1/4 of the price of Subaru ones, and I trust DW to give me the proper compound over the well-intentioned, but usually clueless, guys at the parts store.

I ordered the rail-manifold seals from the dealer, because unsurprisingly I can't find them anywhere else. Cost me nearly $30, but still a lot better than the $100+ I would have spend if I got all of the rings and seals from Subaru.
