Tips for increasing HP on a 1986 LX 2.3?

That's funny because I will be in Geilo, Norway from January till April to enjoy the winter!

As usual I forgot to say: It's a C3 automatic. It's going to be a daily driver for my girlfriend, and her family lives over 1000 miles from us - ergo it has to be ok to drive long distance (aka not 4000rpms at 55mph)... :) Any good aftermarket carburetor I could swap the old Carter 1bbl with?

Just do all the standard hot rod steps that you would do for any 4 stroke engine. In with the good air, out with the bad. Also, changing your rear end gears to something like 3.73 will probably give you the best bang for the buck.

Well, unfortunately, with that car you will quickly hit the point of diminishing returns. Opening up the intake and exhaust will provide a boost in performance and efficiency - but not a tremendous amount. Ignition boxes won't do anything at all. There are no after market 1 barrel carbs available. But Holley makes a couple of nice 2 barrel carbs. But I suspect you'll lose some low end torque while you gain some upper rpm power. Besides, they are pretty pricey. Consider swapping in an AOD transmission. If you can get a used one, it might be worth it for those long highway commutes.

If you can weld I would do a turbo blow thru carb setup. Cheap power!

Job, but I'm really going for the skiing :)
