So, this weekend was very productive

Got my SVX running again, just in case...
Also got my 'Preza on some new rims!


So I elected to swap the 22T heads on yesterday, got started about 9am. I tore everything off the top of the block while I drained the 'coolant'.


Then I tinkered with my turbo oil feed and oil pressure switch.



I purchased a 3/8 BSPT to 4AN adapter on eBay and put that where the pressure switch was. Then, using the bushing from another engine, I put the pressure switch in a galley port on the rear of the block.



No turning back now.


I got the other head off as well. Then I cleaned the mating surfaces, and mounted the drivers side 22T head.



At some point I quickly cleaned up and ran out to O'Reillys to pick up my spark plugs that came in. I'll be using NGK Iridium BKR8EIX, same as Joejoe69 did in his 1.8T.
Then I was able to halfway bolt up the WRX exhaust manifold to see where the up pipe would line up so I could...


BAM! Little bit o time with an angle grinder fixes most anything.

Once I was satisfied that I had brutalized my crossmember enough, I slapped the other head on and then re-applied the timing gear.


From here on its all about the boost!



So after that I got the intake manifold back on and the sun started to get low so I cleaned up and went in.

All in all, I'm very happy with my Sunday. I've never done head gaskets before so I'm hoping I didn't mess that up too bad. I was able to get the old heads off and install the new ones without moving the block whatsoever. Didn't even have to jack up the sides, although it was tricky.
I'm debating on installing my RRFPR now or waiting to see what my AFRs are.

Still to do:
Install down pipe
Install turbo
Run turbo coolant lines
Cobble turbo inlet together
Drill and tap passenger head for exhaust stud
Mount intercooler
Install timing belt end covers
Reconnect fuel lines
Reconnect vacuum lines
Drill and tap ex. manifold for EGT probe
Relocate EGR canister
Heat wrap wiring harness
Fill oil/coolant
Drive?!

I don't see 'Weld patch panel to crossmember' on that list.

yeah, you're gonna wanna box that back in.

- make sure you have an AFR gauge so you can see what you're running. see if you even need that RRFPR. i get away without running it for some reason.

-i'm not really sure about the 95's as far as an upstream o2, but if it has it, you're also gonna need the sensor pre-turbo.

I absolutely DO have an AFR, do you mean the factory o2 sensor before the turbo or my aftermarket AFR o2 sensor?

And will I really need to box that hole in? I think I read somewhere that the crossmember was still plenty rigid... I was planning on swapping to a turbo crossmember when I change out my steering rack but we'll see.

I never boxed my xmember, and never had an issue. I highly doubt a 4"x 4" section is going to matter with that thick of metal. Are you entering this thing in stage rally? LOL.

In my experience, the most tedious part of this endevour was wiring the gauges and plumbing coolant, oil feed/return. Making the tmic fit, etc...still far easier then splicing a harness in my opinion.

Awesome progress, you're getting there! Did you use composite gaskets or mls?

what i meant by that is two different sensors.

you'll need the afr gauge with sensor after turbo. but if you have a front o2 sensor that came with the car, it needs to be pre-turbo.

Prefect, that's what I got going on, thanks for clarifying. I just meant which sensor should be pre turbo, as I do indeed have a stock o2. I've been running without it and the AFR in its place.

... it's been fiiiiiine

I ran back up to Maine yesterday to see Flat4awd again, I picked up an alternative turbo inlet because it's sooooooo much closer to the intake manifold than I thought it'd be. I've read the build threads and seen the pics, but it's still surprisingly tight.

I didn't get back early enough to use any daylight so I basically blue balled myself as far as my impreza is concerned. I just cannot wait to get working on it again!

I realized another impending issue: the thermostat housing is close to the exhaust manifold. So close I'm not sure I can even slide the coolant hose into the housing. Can I swap to another t-stat housing or am I boned and need to change out my water pump? Thanks in advance.

Did you swap to a WRX/EJ22T water pump? It's hard to tell in your pictures but it looks like the EJ18 pump... I'm currently building an EJ18T as well, you really need to swap the water pump as is moves the location of the thermostat/housing to the "front" (right below the timing belt cover) of the pump instead of being on the bottom of the pump. I tried to get away with the factory water pump, but there just isn't enough room with the exhaust manifold where it is.
