My phase 1 ej22 is getting tired and i wanted to do an engine swap. Swap ideas? Emmisions doesnt matter to me. Ill get around it. I know theres decent swap options but i need a little help deciding between a jdm ej20 or any usdm turbo engine or a hybrid/frankenmotor with my current 22 heads. I know my harness isnt very complicated but do any of you have ideas which one would be the easiest to drop in and splice the harness for my 91? It is an auto and id like to keep the same trans until it finally lets go then a manual swap will come into play. Been doing some research but i need real time answers instead of just threads that are years old. Image

Well... it just depends on how much effort you want to put into it.

The 22 heads are sort of the weakness of the engine (as far as power is concerned), so anything while leaving the heads is going to be mediocre at best.

Any full engine or head swap you're looking at wiring and computer work of some sort, none of it will be quick/simple/easy. You could throw the 22 heads on a EJ25D block, someone around here did it once and I can't remember what came of it.

UPDATE!!!
no longer doing an engine swap. I was able together a ton of ej22t and wrx parts for a turbo build. My plan now is to use my current ej22e, set up with the 22t intake manifold, 22t heads, headers, up n down pipe, currently a vf11 turbo but might look for a td05, manual boost controller, I habe the auto 22t ecu from a 93 legacy, wrx top mount intercooler with the stock bov, extra coolant reservoir, 22t water pump, 22t cross member, and quick ratio steering rack.
Currently missing, CAI, all new engine and turbo gaskets, a few oil and coolant lines, and a couple silicone hoses.
Questions now.... With everything i have im sure i can just slap a turbo on it, run 8psi and call it good. So now im looking for decent manual transmissions rear diffs and driveshafts that will swap in. Any suggestions would be amazing, and if anyone sees a problem with my above setup let me know!!!

From my reading, the only thing that is "close to" plug and play is the WRXLink for the ver 1-2 wrx. It can be programmed to run wasted spark, or coil on plug.

Supposedly ESL can do the same, I own one but couldn't find where it says to select wasted spark in the software.

Great resource on converting to run an ej20g ecu - that's where most of the near-plug and play options exist.

Also consider your compression ratio with the n/a short block and the turbo heads. according to marnix's chart the result is 9.7:1, same as NA.

Awesome thanks for the reply! Ill do more research into that ecu. Isnt that the ecu that rob runes for his robtune products? If so i wouldnt mind grabbing one of those and running his tunes if its worth it. But i think a high comp build with my na pistons would be fun until i go with a bigger turbo, different ecu, and new pistons. Any tips as to what i should watch out for while putting the turbo on? The engine does have 240k and counting on it now so i don't wanna push too much boost and blow it. Its running really well right now for being 27yrs old

Yeah that's how you'd run a robtune. Unfortunately his tune is for 8.5:1 or less compression. My buddy Kimo burned up his 9:1 compression block on that tune.

Putting the turbo on is pretty straight forward, id make sure to use brand new lines for the coolant feed and drain.

While your compression will work for probably a long whole on the stock ecu and turbo, you'll need to get something fully tunable to run a bigger turbo. One of the options I mentioned above will work. Or install stock 22t pistons.
