So, I've been wantig to get an extra fuel rail to play around with, and found an NA dsm in the yard. I haven't been able to find any information on this. Does anyone know if the fuel rail's are different, and how?

I might just pick it up anyway to compare. Can't be too expensive from a junk yard.

I do not know if it is the same part number but upon inspection they appear to be identical. Difference would be in the injector.

1g NA to T is the Same, do not know about 2g. 1g to 2g is a bit different in length slightly (2g longer) IIRC.

Not sure on length, but the 2gT rail is clocked slightly different. both 1g rails are the same.

They are pretty much the same mate.

I'm running it on the AMG (NA) and have used turbo adaptors on it. I've also got the EVO3 injectors on it too!

Actually you're right, it's the FPR that is clocked differently as far as the return/vac. line goes.

Sorry Wiz, I was referring to the NT and Turbo.

As for the 2G, I know that EVO123 which are the closest to the DSM 2G's that you have are different. Like you said, they are clocked differently and have slightly different lengths at the ends.
