Default Subaru baja looking for little power upgrade

Hello NOSIOC members, i've just created my account to be able to ask all you guys and girls for a little help. I have a 2003 subaru baja. The previous owner had the ej25 removed and a 98-99 jdm ej20 n/a installed. Its really a great engine in very good condition but it is severely underpowered for a awd car of this size. It only made 115hp new so even just having 3 passengers makes steep hills pretty daunting! I'm looking for the cheapest way to make a little bit more reliable power and i also love the mileage i get with my 2.0!! Under 7.5L/100km or roughly 31 mpg with a baja is pretty sweet! I just want to be able to pull a light trailer with my sled on it so 170 hp is a nice target. I asked a montreal bases swap shop what it would cost to swap a 2.0 turbo and they said like upwards of 6k cdn which is too steep for an old car even if it is still going strong. So friends, any suggestions?
Thanks alot

What the shop told you is correct. You might be able to pick up another 15hp with some bolt ons, but trying to add much more than that is going to require either an engine swap, or boosting your engine (turbo or super), which will lead to a blown motor and then an engine swap.

How about a later 2.5L N/A? That's in the neighborhood of 175 hp. We had an 08 Outback with this and it never lacked for power to do mundane transportation things.

Oh....and expect mileage to get significantly worse.

What kind of bolt-ons we talkin about, 15 hp isnt alot but it's not nothing eather.
The 2.5's reliability issues are what bother me most and mileage too...
If i go catless with less restrictive muffler, i could axpect maybe another 5-10hp?

5hp at best.

Not worth the stink and the noise. If you want to tow more, then you should be looking at a different vehicle.

there is no performance gains to be had on that old engine. Id say leave it how it is while you save up for something else - either a different car or a large bill from the performance shop. what they quoted is in the realm of what I'd consider reasonable.

Alright, thanks guys,
consensus seems to be go for the swap or change car. I agree with that but wanted to see if i had any other choices. I am mecanically inclined and have a very well equipped garage. What would be the gain of doing the conversion myself cost wise? what are the other parts needed appart from the engine and ecu? can i keep my tranny? Say i'm going for a jdm ej20 turbo.
