The car on the freeway going 62 mph does 3k rpm does that sound right?
car currently has 3.90s
I'm a datsun guy and i am not fimilar with subarus what so ever warnings, help, or quirks you can let me know about would be helpful and much appreciated. I have already dealt with the infamous timing belt, right cv axle, valve cover leaks, trans leaks, and an intermitent starter problem.
thanks to all, This site has been very helpful, the people seem real nice and just crazy about subarus. just what I'm looking for. keep em running

Run a couple bottles of Chevron Fuel System Cleaner through it and see if your MPG doesn't improve (that stuff works wonders).

My EA82 Turbo enjoys 3500RPM+ when cruising.

The Nissan R180 and possibly even the R200 should bolt right in. I have some links to pages that list the various Nissan diff ratios.
Another possibility is to run taller wheels/tires. Not exactly easy, but doable.
BTW, I have a '71 510 with an z20+5speed, R180, and corvair rims. fun...

Anyway, as said above, I'm not sure you'd gain much by turning the engine significantly slower. They're kind of gutless down low, and you'd have to really be lugging it to keep the speed up. In addition to using more gas, that's torture on bearings.
You've done a full tuneup, right? Plugs/wires/cap/rotor/O2 sensor?

This may be different for different models, but I've seen warnings elsewhere that for the GL series like my 1988 turbo, higher tire pressure will wear out the middle of the tires fast, and to stay with the factory specified (which I think is 26 -- but don't trust my memory, I don't!).
Now I've only had the 1988 GL turbo for, what, three weeks now -- 240k miles on the body, 60k miles on a swapped engine -- and made one long trip with it.
About 200 miles on the freeway, 30 on 2-lane pavement, and maybe 50 on steep gravel Forest Service mountain roads in mostly 4wd low gear.
21 m.p.g. so far overall. Not what I"d hoped -- but it's back in the local Berkeley shop for a Check Engine (34, EGR solenoid) light that has persisted through three different mechanics' attempts to solve it. Makes me suspect something else is wrong in there.
I'm very glad to see the thread started, I'd been thinking I really wanted to know what kind of mileage, RPMs, tire pressure etc. others report here.
