Subaru Impreza 1490cc replacement engine
Which other Subaru engine can fit into the Impreza 1490cc

A new RS Sport Wagon joins the Subaru Impreza lineup in 2005, replacing last year's TS Wagon. It is similar to the RS sedan, but with more cargo room and a 60/40 split-fold rear seat. The 2005 Impreza is an all-wheel drive sedan or wagon in both 2.5RS, RS Sport, and the performance oriented WRX. The RS sedan appearance is based on the World Rally car and features a 2.5.-liter, 165-hp, flat-4 engine with a standard 5-speed manual or a new 4-speed automatic. The WRX is a turbo version of that same engine, but hits 227-hp. There is also the compact SUV-like Outback Sport wagon, which uses the non-turbo engine. A 2005 Special Edition of this wagon adds more interior conveniences and a rear spoiler.
In 2005, the Impreza WRX gets new 16-inch wheels, a new center console and dash, as well as standard automatic climate control. The new RS Wagon has a sport suspension, 16-inch alloy wheels, a roof rack, a wraparound rear window, and 61 cubic feet of space when the rear seats are folded. For the RS Sedan, a Sport Package offers much of what's on the WRX, including ground effects, sport seats, leather wheel, body-colored mirrors, and alloy pedals. All 2005 Imprezas have all-wheel drive, ABS brakes, power features, cruise control, keyless entry, and daytime running lights, and dual front airbags. Only the WRX comes standard with front and side bags.
The 2005 Impreza is a compact car that's fun to drive, whether for weekend pleasure or city commutes. It is reliable, safe, and packs a lot of features at an affordable price. Owners love the WRX acceleration and and power. All-wheel drive provides added security. Handling is always rated well. Disappointments include a small rear seat, notable turbo lag, clunky shifting with the 5-speed, and below average fuel economy.

Is this possible?? What would I have to look out for when doing this?
Cylinder 1 misfire, I've replaced the wires, coil pack, and MAF and air filter moving on to spark plugs. The car was running fine until I replaced the coil pack. And I replaced it anyways because I didn't want the problem to progress. Thought it might be the wires so I replaced them too, didn't help. Replaced the MAF and it still idles low and dies if I leave it alone. I also changed the air filter because it looked pretty bad. I just bought this car and two days later this happen. What do y'all think? Subaru Impreza 2005 2.5 non turbo, I believe a single cam.
The center digital clock display “flickers” really fast for about a minute then stops. It has happened twice now in the past week.
