I’ve had a Subaru 2.2 with KEP’s California legal setup for ten years and over 120k miles with no problems, other than that my rebuilt 4 speed tranny is beginning to show signs of its age. The difference in power is huge - from about 90hp to 130 - more than a 40% increase. But more than the power difference is the reliability, (also low end torque is nice, in a city with heavy traffic and far too many stop signs). The only work I’ve had done on the 2.2 was its routine, 100k timing belt replacement. It’s the engine that should have been there to begin with.

The van body is rusted and wearing out so I’m now in the process of doing another conversion.

I would recommend going to the subaruvanagon list for more information. It is a very well moderated list with some wonderful, helpful and super knowledgeable people on it. You won’t regret it.
