Fuel rails for 550 robtune?

Post by marsh27 »

Would it be better to keep the stock 22t rails with the 550s or use the na rails? I read that the na rails are better but just wanted to check

It's not a matter of whether they're better or not, it's a matter of what fits. I don't believe the US STi 550 cc/min injectors will fit in the stock turbo legacy fuel rails. They fit the 92-94 non-turbo Legacy fuel rails.

The stock ej22t rails only work for '440' grey side feeds.....also a tune Rob provides.

25d rails also work, and are quite a bit easier to come by around here.

Only with the DOHC intake manifold which only fits the dohc heads.

Hmm, I'm currently running them on my robtune setup without any problems. Stock ej22t longblock and manifold.

Hi
not to argue the point too much more but the bolt holes on the rails are on opposite sides-ej22t/e vs ej25d. Not sure how u made them work?
You can see the EJ20G DOHC (same fitment as EJ25D) rails in my post here http://forums.nasioc.com/forums/showthr ... =injectors
Thanks

Next time I see the car I'll try to get part numbers off them. I could be wrong. I just want to get the info out there if there are other options because around my part of the country ej25's are way more common in the salvage yards.
