as far as the 03 line up goes the US had EJ25, EJ20T and EJ25T-might actually be 04's for that. What kind of car is this? just a plain Impreza?

for help on that i would say talk to a guy named Matt Monson. just drop him a PM and ask him. He know pretty much all the subaru line up. But if you are in the Us and actually have a RS and just have your engine messed up, let us know and then we can give you lots-o-help.

2.0L N/A impreza's were sold outside of the states.

I remember hearing of somebody in canada that reprogrammed a stock ecu, but I am not sure if the exact results.

do any of the piggybacks allow for rpm raising? like a unichip or something similar?

The Link does. But the limits of your RPM range will be based more on what your valve train can handle.

You will probably have a serious valve float problem at higher RPM's with an N/A Subaru motor.

I would not recommend raising the rev limit above 6500 or MAYBE 7000rpm's TOPS with out upgrading your valve train. (Springs/retainers/etc)

um, running boost dont even think about taking it to 6500 w/o valve train if ur runnin like 10 psi+

upgrading springs is easy, and relatively cheap, ~400, if i can do it, you can do it

Like the others have said, unless you upgrade your springs, you do not want to bump your redline. Do a search in this forum about it. There was a long discussion we had about it when Graham was trying to decide what to do about heads on his RSTi build. Or you can just wait until totoherbs comes along and links it up for you.
