My conversion was essentially Small Car. But some things were not. My
tranny adapter came from Outfront Motor Sports for example. My harness
conversion was done by Busaru.Fabulous job. My engine, a ej2.5 came from a
2005 OUTBACK. Very problematic. I highly recommend staying away from that
one. It is a combination of PRE 2005 and new stuff for the 2006 engines and
it is a poor mix for conversion. Lots of headaches.I bit into it before I
knew. But Mick at BUSARU knew what to do and saved the day, but it was
complicated so I recommend staying away from that one.

On later vans getting the tach right is an issue. The simplest way to deal
with it is to get the tach modifier from Busaru that simply plugs into your
wiring harness and gives you a proper RPM readout. Far better than sending
your tach out to be modified or trying to do it yourself. Easy to mess up
your tach. I got the device for $50 but it probably has gone up since then.
