The 98 2.5 as found in the Impreza RS has quad cams, but the bottom end is too weak for power modifications. My son has a 98 RS with a big Garret turbo and a big intercooler. It is quick, with minimal lag (higher compression equals quicker when not in boost), but he has eaten a cylinder liner and his crank has walked. The walking crank phenomenon is well documented by other performance tuners. In 99, they went to SOHC, but it is a really nice SOHC and they strengthened the bottom end.

There are hotter Subaru engines than the EJ22T, but I doubt if there are many that are closer to bulletproof.

ps I absolutely love this user group. Having the rest of you out there sharing tech tips is like a dream come true. I spent the first six yuears of Legacy Turbo ownership thinking I was the only guy in the USA who was interested in tuning these remarkable cars. Thanks to all pof you who regularly contribute.

End of 98 they quit using the DOHC 2.5 litre engine.
Our service guys at our dealership have the opinion
that it was one of the lower quality engines Subaru
has made. They said that cylinder 4 has a tendency to
go out around 120K. Something to do with extra heat
near there or something.

You mention the '98 year, but the DOHC was made for
more than that year, were all the DOHC 2.5 liters
troublesome, or just the '98 year? Thanks,

>From what I've been told it was all the years of the
2.5 I think they were 96-98 and in Outbacks and
Legacy GTs mainly. They were pretty good engines til
around 120K and this is just something they have seen
happen a number of times. I'm sure they don't all
have the problem but they say it is a possibility.
