Let's get a thread started about a full motor swap. I'll start with what i needed to do for mine, but im on my phone at the moment. So, just to get this started, i started this thread.

Depends mostly on your budget, and if you will be doing the work, or having a shop do it. If cost isn't an issue, I would do a full STI EJ257 drivetrain swap.

If you want a lot of torque but don't want a turbo go H6 (they also sound vicious)
I voted for the hybrid (built 257+207 heads FTW)

I went with 2.0wrx bc i wanted a 2.0 in my gc, plus i'd like to run a 207sb with the 205 heads(i used to own a 93 legacy SS, I should've just used that block)
I did use the turbo cross member from it, and the rack from my gc. You can use other crossmembers though. Any turbo x-member or you can hack your N/A one(oh god, please don't) to create clearance for the up pipe. Some posts I've read say a n/a front sway bar won't work... Mine did...Idk if it rubs bc the car hasn't been driven yet. But i also have a cusco 22mm fsb for a wrx, so i won't worry about it now

Dont do a hybrid build!
If you get the ej257 block, bore the heads out to a 2.5. You get better mpg and it's a bit easier to tune.
id recomment the 2.0 block though

id recomment the 2.0 block though especially in a gc, like mine. now i can't run a full 257 swap w/ drivetrain because if my injury. So a 205 was perfect for me bc i can get a wrx as a 4eat, speaking on tranies, is there any differences in a 5eat?

(I'm talking about doing the right way) After my raw performance built hybrid blew, i did a lot of research and came across a company that has a cnc program to cnc the heads to a 2.5 head and they had a huge list of reasons why running a 2.5 block with a 2.5 head is better. It's been awhile since i've read it and i dont really feel like looking it up. If you are going to spend the money to drop a ej257 in your block, spend the extra 400 bucks and just port your heads

That's only assuming it's a 2.5 hybrid you're leaving out 1.8, 2.2.. . 1.8sb 2.0 heads 2.2sb 2.5 heads Etc...

I did a 2.0 wrx swap into my RS starting with a bare case and putting all stock internals in it. Its easy, parts are cheap, and the ecus are easier to learn how to tune on. I have been running around 20psi through it with a vf34-16g for over 2 years now with several autoxs and it holds up great. 2.5s scare me because of the ringland issues... Frank can attest to that. If you have any questions on my swap I will gladly answer them. I think the bore on a 2.2 is between around 96mm but dont quote me.

Id go STI if possible. I started with a 2.0, then blew it, now its on a hybrid. Ive had 2 hybrids, they are fine. If I decide to go big power though, Ill just use sti heads and disable the avcs, or just have my wrx heads done. Just have to get a tuner who knows what they are doing. Once you swap, youre gonna want more. Better to start on a 2.5, blow it and rebuild, then start with a 2.0, blow it, and rebuild. Start with an sti swap, and youll be alright. Shit, my sti has 214K miles on it, and yes, has a little low compression on 4, but still runs like a champ. Someday, Ill find that perfect H6 that someone wants to just give me, and itll be on.

Thinking about doing a swap. Had huge blasts of white smoke pouring out of my exhaust and coolant disappearing. Drained the oil and had two oil catches full of melted chocolate milkshake lol. So now it's either replace the head gaskets and keep the motor with over 200k on it, or do a swap while I have the engine out. Weighing both options and not sure what to do. Reading through here and knowing my budget, a 205 swap seems to be the way I'd go if I swapped. A 257 swap is almost double from the prices I've seen, plus a tranny swap. I wouldn't mind keeping the 251, but I'd want to have it rebuilt so it would last, but I think having it rebuilt costs about as much as buying a 205? I'd like some input from some people who may have been in my situation. Here's the link to two engines I've found: www.ebay.com/itm/190966092552?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AITwww.ebay.com/itm/200976577658?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AITThere's a lot more engines out there, those are just two examples I found as possibilities. My wife's vote is to go turbo. She wants me to do an sti swap, but our budget says otherwise. Thanks guys!

Might be able to split the difference with an EJ255. If you're willing to do a turbo swap, or make sure you get one with a VF52, it's really not going to be that different from an EJ257 in terms of power levels. Just keep in mind there's a few different EJ255s floating out there depending on what car it's out of. Also might try to find a wrecked wrx somewhere that the motor is still good. I know ryanr is a big fan of the 2.0L, and iirc, that is the swap he did on his RS.

I would look into a usdm wrx swap either a 255 or a 205, do a little reasurch on which one you want and the prices. Then get ahold of iwire and get a quote on a harness merge. Then add in the price of some pizza and drinks for your buddies to help!

Yeah I am thinking a 205 is the route I would go. I looked up iwire yesterday. I think it was ~$650 for an early wrx merge. The ride down here to my in-laws garage would be a nice cruise for everyone I found that 02 wrx engine in Illinois, but its got 130k on it. Dunno if that's a lot? I've been researching a lot of threads, still got a few more to go through.

If its within the budget, I would look into a rebuild (pistons, rings, rods, bearings etc) sense your going through the hassle might as well do it right and then the motor will last another 200k. Maybe talk to Sean at vigilant about assembling the motor and doing the machining.
