As far as i know the current 2.5l engine is the same as one from 97
Impreza GT with only diffrence that it is now again non-interference.The
power and torque figures are the same.Those from 96 should be avoided
due to cams and less power.
As of now KEP is not ready to offer late model engine conversion and it
would be
totaly to us to work it out and it can be pretty hard depending how we
can solve the trouble codes issue, new exhaust system, wiring etc etc
etc.The main issue being electrical. And, after all, it has to be
approved by CARB in our state.Lots of work!
I totaly agree with you that it would be a great engine to use even
though my 2.2 feels
stronger than 130hp it is rated at.

Is the 1997 Impreza 2.5L engine the same as the current 4 valve, SOHC
2.5? Edmonds.com said the 1999 redesign was done specifically to
increase the low speed tractability and it was successful and the
engine has noticeable more grunt than the earlier 2.5 engines. Was
this same engine in the 1997 Impreza? What is the factory designation
for the engine? The same in Japan as US? Does anyone know a factory
Subaru mechanic with access to the factory manuals and power graphs
that we can scan and add to the library of info we have?There will be
a lot of these late 2.5L engines coming into the dismantler market in
the next few years. It would be good to work on this conversion.
Wiring, exhaust, cooling. This power would be a significant
improvement and parts and service would be available for a long time.
A mild turbo would extend the power down very low, which would be very
good for a Vanagon that has to work carrying people or gear.NelsonSF

The Legacy or Impreza 2.5l engines that might work were from
year 1997 till current.
They all make 165 hp and 162 lb/ft of torque.The big "but"
is need for custom made exhaust, more complicated and
unknown wiring, possible big problem with smogging(may need
a friend in smog shop).It would be great to see it work!
