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 :grin:

https://sl-i.net/FORUM/images/imported/2014/02/Lamco-1.jpg


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 :smt023 and have a garage to work in :grin: :grin: :grin:

https://sl-i.net/FORUM/images/imported/2014/02/LeggyGarage2-1.jpg

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

Cleaned up the pistons and replaced the rings

https://sl-i.net/FORUM/images/imported/2014/02/Pistonrings-1.jpg

https://sl-i.net/FORUM/images/imported/2014/02/Pistonclean-1.jpg


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

https://sl-i.net/FORUM/images/imported/2014/02/Oilseprearmain-1.jpg

[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 :D

[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

https://sl-i.net/FORUM/images/imported/2014/03/Rearmainoilinstalled-1.jpg

[Beauchemin]

Made some forward progress today

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

https://sl-i.net/FORUM/images/imported/2014/03/Cleanbellhousing-1.jpg


Also slapped the heads on :grin:

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!!!!

[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

https://sl-i.net/FORUM/images/imported/2014/04/200k-1.jpg

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 :smt023

https://sl-i.net/FORUM/images/imported/2014/06/10mmoilpump-1.jpg

https://sl-i.net/FORUM/images/imported/2014/06/Oilwaterpulled-1.jpg

https://sl-i.net/FORUM/images/imported/2014/06/Oilwaterinstalled-1.jpg

[Beauchemin]

Small but forward progress, oil feed setup installed :smt023

https://sl-i.net/FORUM/images/imported/2014/06/Oilfeed-1.jpg

https://sl-i.net/FORUM/images/imported/2014/06/Oilfeed2-1.jpg

[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.

https://sl-i.net/FORUM/images/imported/2014/06/25Dhead2a-1.jpg

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.

https://sl-i.net/FORUM/images/imported/2014/06/25Dhead-1.jpg

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 :smt023

Some parts did arrive though!!

https://sl-i.net/FORUM/images/imported/2014/07/06Tmicsparkplugs-1.jpg

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

[Beauchemin]

Got home to some more parts today

Out with the old and in with the new

https://sl-i.net/FORUM/images/imported/2014/07/Mounts-1.jpg



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

https://sl-i.net/FORUM/images/imported/2014/07/Oilfeedrear-1.jpg



Timing belt installed

https://sl-i.net/FORUM/images/imported/2014/07/Timingbeltinstall-1.jpg




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

https://sl-i.net/FORUM/images/imported/2014/07/Updownpipe-1.jpg

https://sl-i.net/FORUM/images/imported/2014/07/Uppipefitting-1.jpg

[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.

[Beauchemin]

Thanks for the info man :smt023, i will deff. be looking into it a bit down the road


For the time being i got a few more things in
Exhaust manifold and ngk wires

I had a little fun a mocked it up on the stand, just need my clutch and flywheel to come in
Hit to auto part store for a thermostat, fresh coolant, oil and filter and we are good to go!!

Those shots of the mock up are inspiring! Keep up the nice work!

[Beauchemin]

Those shots of the mock up are inspiring! Keep up the nice work!

Thanks man!!! Its been a long and slow build but it finally getting there, cant wait to hear her fire up!!

[Beauchemin]

Got my clutch!

https://sl-i.net/FORUM/images/imported/2014/07/Clutch1-1.jpg

Will be making a trip to the Subie dealer for my thormostat later this week or next, after work on the 29th ill be pulling her in the garage and start pulling and swapping!!!!

[Beauchemin]

Stopped by the Subaru dealer and scooped up my thermostat. Got an oil filter while i was there as well. Now for oil, any input on a good oil for this build would be? I was thinking I would just used mobil 1 5w-30, but have heard a lot of talk of the Rotella T6 5w-40

https://sl-i.net/FORUM/images/imported/2014/07/Statoilfilter-1.jpg

[98legwag]

I have read for some reason Subaru engines don't like Mobil 1. But the internet told me that so take it for what you want.

[Beauchemin]

I have read for some reason Subaru engines don't like Mobil 1. But the internet told me that so take it for what you want.


Right 50% of post say the mobil 1 leads to spun bearings the other 50% swear by it.... Thanks for the imput though!

[Beauchemin]

So my buddy is awesome!!! and came by yesterday to give me a full lamco pack

A wrx came through the yard, there were no tags for the pack so he grabbed them for me, has the full harness still was plug and play!! It is just missing a oil temp sensor, but moved over my boost line so boost and volts are good, oil temp soon to come :smt023

https://sl-i.net/FORUM/images/imported/2014/07/Lamco6-1.jpg

[Beauchemin]

Very nice. Well done sir.


Thanks man!

[Beauchemin]

Had a oil leak coming from the bottom front pass head, was thinking either value cover or cam seal. I took a closer look and seemed as it was coming from the cam shaft cover, slipped the bolts out

https://sl-i.net/FORUM/images/imported/2014/08/Yikesbolt-1.jpg

:shock: :shock: :shock:


Glad it cam out!
Threads in the head are fine a new bolt threaded right in and now am leak free :smt023

[Beauchemin]

Picked up a 02 wrx momo wheel the other day and was able to slap it in last night. So much better thank the stock Lgt wheel!!!!

Out with the old

https://sl-i.net/FORUM/images/imported/2014/08/WheelLgt-1.jpg

In with the new :grin:

https://sl-i.net/FORUM/images/imported/2014/08/WheelMomo-1.jpg

[arvinlim]

Planning to do the same with my steering wheel, did you had a hard time installing the new steering wheel is it just bolt on? :)

[fwa2500]

The Momo looks just right in our cars, doesn't it? I love mine. Awesome build, dude!

[Beauchemin]

Planning to do the same with my steering wheel, did you had a hard time installing the new steering wheel is it just bolt on? :)

It is very easy to swap, air bag clip was the trickiest for me haha, you do have to change over the cruse controls. Otherwise it is just about bolt on, here is a great diy link

The Momo looks just right in our cars, doesn't it? I love mine. Awesome build, dude!

It really does, feel like it as well!! So glad i got one
and thanks, you wagon is awesome! so clean, i cant wait until i can get my car to that point!

[peugoby]

Great build. I love the way the MOMO wheels look & function in our cars. It's one of the best upgrades in my opinion. How do you like that turbo setup? How does it run? Are you on a standalone EM or running the stock ECU?

Thanks man! I also am loving the momo, huge upgrade!

Im loving the car, runs awesome! The turbo spools very quick witch is awesome lol. Pulls nice and hard! Just took took her on a trip to wicked big meet's track day, 120 mile round trip for me, had no problems, even got to play with a blobeye sti on the way back :grin: No em, stock lgt ecu

[Muse]

I saw your car there. Parked like, five cars down... I had the silver BK with the green scooped hood and white quarter panel.

[thenines']

I saw you pass me on the way down to Wicked Big Track day last weekend :smt006

[blanquelm92]

You inspire me lol loving this build bro :smt023

[Beauchemin]

Picked up a Rallitek pp6 and a Innovate lc-1 wideband the other day
Now I can get her all dialed :smt023

https://sl-i.net/FORUM/images/imported/2014/09/Pp6-1.jpg

[Beauchemin]

It has been a while since i have been able to work on the leggy, planning my wedding has been sucking up all my time and money. But i buy a new Bosch wideband sensor and wired in my Lc-1. Now just need to find time to get the Smt 6 in and start getting the most out of it :grin:

https://sl-i.net/FORUM/images/imported/2015/01/Db1-1.jpg

[Beauchemin]

Ok so it's been a while since I've been on but I have made a little progress on the legacy. The clutch couldn't handle the boost anymore (Why I put a stock clutch in...idk) and the motor started to leak a little oil so out she came

https://sl-i.net/FORUM/images/imported/2015/12/image_8-1.jpg


The cheapo eBay header (that I had to stretch to fit) ended up rubbing against a line in my rack so much it made a hole and started to leak fluid. So grabbed a rack and decided to swap to the legacy ss subframe

Nice work mate!

[dynonacht]

lot of mixed reviews on the blue belt, be sure to give us your input. looks good dude.

[Beauchemin]

Yeah I've seen some mixed on the blue belt, it's said that the blue wears off onto the rollers and throws off timing. I will check the belt/rollers/timing every few thousand miles and see how it holds up, if the blue does indeed start to wear onto the rollers I'll swap out for a oem belt, just couldn't pass up the deal I got on this one
I'll deff update on how the belt holds up, thanks for the heads up though
