[Beauchemin]

When i bought the car it did come with stock gt "snowflake" wheel, 1 with a crack so got one from a pull yard and decided to paint them up

Sanded down and used a can of etching primer



Then a few coats of gold and clear coat



Was able to score some Hankook Ventus v4 215/55r16 for cheap







With almost 200k on the stock ej25d its ready for a now heart, im currently working on a DOHCEJ22-T build

Stock ej25d intake mani, i stripped down, cleaned up and painted










I have a set of ej25d heads as well, they are modded with a coolant and oil return



Also did some cleanup on the heads







When i got the car it had the stock lgt front bumper but car had been in a small accident and the front bumper support was bent and never replaced, my buddy scored me a outback support bumper and fogs that weren't tag on a car that came into the scrapper










One day i was bored and decided to instill my lamco boost gauge, to bad it never make it past 0..... yet




Was delayed on the build for a couple months as my wife and I purchased our first home and had been working on the sucking up both money and time, but i now am officially a home owner and have a garage to work in



No pics but got my inner/outer tie rods and lower ball joints in, as well as replaced my leaky power steering pump



And then back to the frankenbuild

Ej22e with 134XXX on it



Parts came in!!



Ej222 headgaskets match up perfect with the ej25d heads



How it looked when i pulled of the 2.2 heads



Cleaned up the pistons and replaced the rings






I just got in my rear main seal as old one looked like was leaking a little, also got the separator plate as the 2.2 motor has the plastic garbage cover on it originally. Hoping this weekend ill have time to install them and get the heads and intake all bolted up

[98legwag]

Good work sir. I approve.

[BDAlex95]

Looks great. Welcome to the forum. What have you done to the GT bumper? If it's not all cracked up I can take it off your hands

[Beauchemin]

Thanks guys, its still hanging around with the stock gt fogs, ill snap a few pics tomm and message you

[Hinyo]

Liking the build cant wait to see the turbo progress. New ideas and ways of doing thins are always welcome. Nice to see someone showing pictures of the process of painting and intake i plan to do mine soon. Still not sure what color but this give me hope of it not being so hard to do.

[Beauchemin]

Thanks, i take pics of everything haha. Was quiet easy as well, toss in on a couple pieces of wood to make painting the bottom easier. I couldn't resist the wrinkle red paint

[Beauchemin]

Got the rear main seal in and the oil separator plate all sealed up, now to clean up the bell housing and get the block back on the stand, get the heads and intake manifold all bolted up

[Beauchemin]

Made some forward progress today

cleaned up the block a little, here is a pic to compare to the one above




Also slapped the heads on



As well as intake mani and a new knock sensor






Then ran out of parts..... for now haha

[Beauchemin]

Have not got to do much with the car for a bit, working on the house or helping my brother with his acura build, but it was a beautiful day yesterday so gave her a bath, so here are just some random pics, hopefully ordering a water and oil pump for the frankenbuild next week

WASHED!!!!




Stock EJ25D





Daughter snapping tons of pics while we were out and about haha, first interior pic!!

[LeggyxPower]

Very clean man, can't wait for more mods!

[Beauchemin]

Thanks man, i second that, i want this motor in!! The OG motor runs like garbage haha. I like the brighton man! I used to have a 98 Outback, miss having the wagon

[Beauchemin]

The wife ending up having a break down the other night, so off the the rescue i went hahaha
On the way back i ended up looking down and caught this



Hopefully the next updated will be better....

[Reuben]

Cool build!

[Huffer]

+1, agreed.

[Beauchemin]

It has been awhile, i have been busy with up keep and working on the house but i did buy a 10mm oil pump and got that installed as well as a new water pump

[Beauchemin]

Small but forward progress, oil feed setup installed

[grayguy]

There is an oil galley on the back of the passenger side head that makes for a much cleaner and less leak prone oil feed

[grayguy]

Ok, this hasn't really been covered in this thread yet, and I've gotten a few PM's about it. Here's a few quick pics and an explanation of how to set the NA heads up for a turbo.



It's been almost 3 years since I did this, so bear with me. I believe the Adapter for the Oil feed is a 12x1.25mm to -4 AN fitting.

For the water line, I drilled and tapped it for a 1/4" NPT fitting. I then used a (I believe) -6AN adapter.

For the Oil return, I just bought the closest size drill bit I could get to matching the oil return tube off the 22t heads. In hind site, I should have used a larger tap/fitting and used an AN line here too, I still may rework it to do just that.



Feel free to quote/ edit this if you have more details on the sizes, like I said, it's been quite a while since I did this.

[Beauchemin]

Thanks for the idea man!! i was think about it but i had all the fittings for the oil press sensor so decided to slap it on, but its a tight fit to the altenator and think im going swap over to the rear gallery

[Beauchemin]

grayguy was spot on with the fitting size, 12x1.25mm going in the back of the head and my oil line is -4an fittings so i did order myself a fitting and will be swapping the oil feed over

Some parts did arrive though!!



should be swapping the motor in the end of the month while the wife goes on vaca

[Beauchemin]

Got home to some more parts today

Out with the old and in with the new





Changed the oil feed, used a 12x1.25mm to -4an fitting (thanks Grayguy!)





Timing belt installed






Just waiting on my wire set and exhaust manifold!! Going to order my clutch and fly wheel next week and then going to get her in

[r3v_v3ng3]

Its coming along! Are you gonna use a turbo subframe or notch the stock one?

[Beauchemin]

Thanks man,

I actually have custom up/down pipes for it that clear the stock subframe and let out where the stock cat would

Here are a couple shots from my old obw

[Reuben]

Why not just get a turbo subframe? That's what I did on my project, so I could run a factory turbo exhaust manifold and get the classic boxer burble. Can also slap on a wrx k-brace when you do that too.

Also, do the USDM DOHC heads not get the blanking bolt on the back of the right head? You just whip it out, and put a factory banjo bolt and oil feed like on, done.

[wentz912]

You CAN use a WRX crossmember you know, then your UP and DP can be off the shelf parts.

[Muse]

Yeah, but if he's already got the custom pipes, why do all the extra work?

[Beauchemin]

I was going to swap in a legacy ss crossmember but i already have the custom pipes sitting in my garage from a old build, right now dont have the funds for the crossmember and want to replace the rack while im down there. For now ill be running the custom pipes with my oil feed coming off the back of the pass side head with a 12x1.25mm to -4an adapter

In the future she will get a new rack and a turbo crossmember (thank you wentz912, didnt know i could use one off a wrx, will be easier to find a wrx member than the leggy ss member), as i will want the ability to swap in upgraded exhaust parts with ease, and yes get the scooobie brumble

[wentz912]

It's not a "bolt on" fitment using the WRX crossmember, so to speak. But from the best of my understanding it is JUST that the lower control arm bushings on the WRX are "wider" (IE the tabs they go between are farther apart). So, one is left with a few options. First, shim the Legacy bits with washers or the like. Second, put WRX bushings in the Legacy LCA's. Third, put wrx LCA's on along with the crossmember.
