The problem with this entire equation is that it is a Subaru and will grenade anything you toss into this vehicle.
It's been fact a few times on this build.
As someone who is on his second EJ25 at 137,000 miles in a '99 Forester... I'm inclined to (somewhat) agree. That said:
Save your time, money and efforts and move onto something else.
An EJ25 can be made into a reliable engine, but it has to be done right and they don't respond well to thrashing. I started out with EA81 Subarus (Brats), and the longevity differences between the two are night and day. Subaru pretty much lost the plot when they went to timing belts, and again when they dropped low-range transmission for the US market.
Wow! Dont give up on this subaru, and for God's sake, do not put a 6cyl in it LOL
Disagreed. I've seen an overall-better survival and longevity rate on EZ30 engines than EJ25Ts, though there are fewer of them out there and fitting one to a Forester is non-trivial. If you want both power and torque, the EZ30 is a good choice provided the donor has been looked after. Just don't use any 4EAT or 5EAT with it that has VDC; VDC is a giant heap of crap, and most EZ30-equipped vehicles had it.
Agreed. Peak power miles up in the rev range really sucks on the trail, as well as the vulnerability issues associated with a turbo. To make my bigotry clear, the only way I like turbos in trail rigs is on diesels.
Just my $0.02, but the H6 (at least in 3.0-litre form) is a pretty decent lump.
