Is the 1g Fuel Rail better than the 2g?

[98TsiAWD]

I plan on getting a 190 pump, so I dotn need an FPR so that is not what I need it for. I am just curious if it flows better or anything?

No it's not. I compared my 2 rails and saw no difference.

So what IS the difference between the two? There's gotta be something or else all the 1G AFPRs out there would fit ours too.

The difference is the bolt holes for the FPR on the 1G and 2G are different

actually i was told by someone who knows ALOT that the 2g rail is actually slightly better then the 1g rail but nothing noticeable

The only difference is the ends of the Rails to my knowlage. The 1G is shorter and the 2G is longer, and bolt pattern for the FPR. The rail aren't different in any other way except for the outer design. I real don't think there is any performance aspect of any rails, between the 1G and 2G. Remember just because it's newer doesn't mean it better.

I asked this in another thread, but I'll ask here too to be safe: Will a 1G (91-94) NT fuel rail work too?

 

[Awdboost]

That I don't know.

One from a 4g63NT will probably work but not a 1.8

Yeah, that's what I got. I tried running a part number search in the CAPS system on my manual CD, but it was my first time using it-- I think I was able to determine that it is the same part for 4G63 turbo and non-turbo 91-94 1Gs. Thanks John!

Does anyone know or actually measured to see if there is a difference between the non-turbo and turbo 1G fuel rail?
