After driving a 4.44 swap around for a while, I'm beginning to think 4.11 is probably the sweet spot between 3.9 or 4.44. At least as far as acceleration goes coupled with highway driving. 4k rpm at 80mph isn't as bad as I thought but man the Ej22 just guzzles gas at that speed.


Well, I'm def not building this for economy heheh. Is there a noticeable difference between 4.11 and 4.44 acceleration wise? Iwangofast! Should I hold out for a 4.44?

I'll probly go 4.11 for the meantime to get rid of the CHATTER.
Yep. You'll notice a big difference in acceleration.

I've been waffling around like crazy on what to do with all my cars, but I think I've got a plan nailed down. I'm gonna move forward as planned with my GM, she'll get a built 2.2 with early Legacy RS heads. The WRX will get a 22e short block if the heads are salvageable, and the RS will get a rebuild with STI rods and pistons, hopefully. The knocking is slowly but surely getting worse.

These finally showed up so I'll bring them to the machine shop first thing tomorrow!




EJ22G!

Not as much progress as I would have liked, but that's life.


Picked up some Tiens on WRX struts for cheap. Turns out they're lowering springs, but that's fine with me.



Chopped out the lower section of the center radiator support bar thing, to make room for a front mount intercooler I've had sitting around forever. I used a bracket I found on a job site to stabilize the remaining portion holding the hood latch. Worked a treat, everything is sturdier than stock!



Scooped up a beautiful CSF aluminum radiator. Thanks GC Beater!


And after I order some ARP head studs, I'll begin my monster 2.2 build!
EJ22E Block
Wiseco Pistons
Manley Rods
ACL Race Bearings
EJ20G HUGE Port Heads
TD06-20G?

Should be good.☀

Fmic

Got my front mount intercooler mostly mounted up. Once I add a support down from the crash bar, she'll be rock solid.



Also moved my power steering fluid cooler to one of the fog light holes. I may relocate it yet again if I decide I actually do want brake ducts...

Random update:

Got my case halves back from the shop a little while ago, but they weren't hot tanked like I asked, only the head mating surfaces were cleaned, and, if the invoice is accurate, they bored the cylinders to the wrong diameter... It says 3.8385, which is the diameter of the poison. Being forged slugs, they need extra clearance, and I would've expected that to be included in the measurement under cylinder bore, no? So I think I'm looking for another machine shop, and the EJ22G build is postponed.

This shop looks good, anyone have any feedback?
Engine Rebuilding Performance Marine & Vintage - Automotive Machine Shop : MA,CT,RI,VT,NH,ME,NY,NJ

On the home front, I tapped a 98' 2.5 head for turbo oil return and coolant feed. Already has the port for turbo oil feed, just plugged with a bolt. I'm gonna use these DOHC heads on the '05 LGT(STI) short block I picked up a while back. Should be good.



And started mocking up my gauge pod. It'll be pretty simple, just a thin steel or aluminum half box, set into the dash in front of the removed center vent. I intend to keep the HVAC controls. I'm not much of a fabricator, but this seems simple enough, we'll see what happens.




Not sure what I wanna do today...
Clean-sand-paint wheels
Swap in new steering rack
Clean-disassemble-clean-sand-clean-paint-clean calipers
Redo engine wiring harness
Redo dash wiring harness
Redo ECU/FIC6 harness
Swap in Invidia DP
Sigh

Got the engine harness done, just ran out of large plastic sheathing. Now it doesn't run directly over the turbo!






Also discovered what I HOPE was the cause of the full throttle hurkey-jerkey I was experiencing. This is where the returns from the fuel rails tee together and go into the fuel pressure regulator.


Yup, FPR is backwards. ?

Edit: also realised I forgot an O ring behind the oil pump housing. ? ?

Welp, I can't stick to a plan to save my life. With the discovery of my new 1997 LEGACY GT-

-my plans have again changed for the little 2 door Impreza. I'll be putting the H6 back in and going for broke. I'm thinking FP Red, there's a Red and Green on eBay now, 1300 each. I'll be holding off for now, but I like to keep my eye out.

Anyway, I drove about an hour West to grab these!

That's a slightly modified RallyArmor skid plate for the 1g Impreza, and next to it is it's replacement, a very solid home made 'upgrade' that seems like it'll fit fine and is waaay more diesel.

...$50 for the pair, what now! AND he threw in a band new brake seal kit, brand new brake line, and a brand new O2 sensor for free! I could've died. He's still got a few things I may go back for.

Anyway, much wiring, welding, and general mayhem awaits my '95, and it's gonna be awesome.

Major surgery the past two days! Everything came from the 02 RS, including the trans which is originally from a 98 outback.
I replaced the transmission (and rear diff and driveshaft), which finally lost third gear mid pull on a slight incline. It certainly was NOT the H6, the trans would've let go with the turbo 4 as it was much, much faster. The break happened at about 5k, so not like I was jarring the trans with rough shifting. I think it was cause I missed third and grinded it harder than I ever have in my life recently.
I also replaced the old leaking fuel tank with a newer one with all the sensors to make the EZ30 ECU happy. I also also replaced the rear subframe, rear control arms, lateral links, axles, knuckles, and 'T' brace. Unfortunately they're still on the og bushings but it's a vast improvement over what my 95 had going on. This also means I now have brackets on my lateral links to attach a rear sway bar! I have a bigass adjustable one I'll throw on after I've gotten used to the refreshed underside of the chassis.
A few complications arose in the form of not one, but TWO rotted sets of rear brake lines! Apparently the factory lines disintegrated long ago, and were replaced by someone other than a mechanic. Those decided to snap just about everywhere while I was disturbing things under the car so I took them from the RS as well. Unfortunately, on both cars, the lines that run the length of the chassis and are 90% inside snapped on the small part that's outside. So now I have no brakes for the moment, good thing I can downshift!
I couldn't get the speedo cable out of the 95 trans. The part meant for a wrench is plastic and soft, so out it comes with the trans.
Also I seem to have lost the correct linkage, and the 95 shifter linkage doesn't match the 07 linkage on my 98 transmission... I wire tied the shafts together but it's FORKED.
AND GD abs sensors don't plug and play, they need to be spliced. I'm not even trying to get the sensors out of the hubs (wait for the pics).

The good:
New trans has all the gears and none of the shaft noise! Shorter 4.11 gears should mean more grins when I can safely romp.
Fuel tank no leak.
Smoother, quieter ride.

The bad:
No brakes
No speedo
Can't access 5th or rev due to sloppy shifter

To do:
Fix brake lines
Locate and install my damn shifter
Install speedo cable
Swap front end stuff
Correct a wiring issue
Connect fuel tank sensors
Install interior
Adjust E-brakes
Somehow transform tires piece of rust back into a car

Oh yeah, I picked up a GT35 with rotated pipes for this thing... I am very excite!
