^+1 Thanks again. TD

For future reference and if anyone can corroborate, I got this info from another Subie site:

Hi, +1 on everything mr. 'grossgary' listed. -AFAIK, nothing before about '99 had any ECU updates avl.. I was looking for tuning options on a '98 Forester (same as yours) and there was nothing. 87 unleaded is their drink of choice. -If you've got a code reader/scanner/clearer I'd clear the codes after replacing the KS. -I'd say your <22mpg is right in line w/the Subaru est. #'s. -The 'torque box' (football) you're replacing may actually affect your power and noise level. I realize you're doing it for aesthetic reasons, but it may shift the power band, which may or may not actually be better for drivability. It's kind like people putting on an aftermarket intake. -I'd replace the CTS. They fail. - I wouldn't spend the $ on synthetic ATF; buy the good but regular stuff. I've not read where it makes a difference in the way the car shifts. If you've not read my posts about it (or others), I don't recommend getting the tranny chemically flushed or even a 'power-flush'. Jut drain/refill/repeat 3x to replace the old fluid. I would add an aux. tranny cooler. Heat seems to kill the Subaru 4EAT more than anything (other than neglected fluid). 1998 EJ25D specs: Engine model EJ25D Engine type Horizontally opposed, liquid cooled 4 cylinder, 4 stroke gasoline engine Engine displacement 149.9 cu in. (2,457 cc) Bore 3.92 in. (99.5 mm) Stroke 3.11 in. (79.0 mm) Compression ratio 9.7 : 1 Firing order 1 - 3 - 2 - 4 TD

Hi, I have a '93 Impreza and I'm looking to upgrade the stock 4EAT - it's not dead yet, but I want to be prepared. Looking @ the '91-'94 Legacy SS/TW or '96 - '98 Legacy Outback, GT or LSi or '98 RS (basically something that can handle more power when I upgrade the engine). My main concern is if the CONNECTOR(S) on top of the transmission - by the pitch-stop- work w/the 1993? And will the TCU in the '93 work w/the newer 4EATs? I know I'll need a different rear diff as the 1993 is a 4.11 and the others are either 3.9 or 4.44. Thanks to John - "johnceggleston" for great info and I'd like to hear from anyone that's done this swap/upgrade/replacement. Thanks, TD

Thanks guys..that seems to be the issue - expecting a 3 bolt-hole gasket - which doesn't exist.

Hmmm, I'm now wondering if the 'new style' is just the 2 bolt hole.....I was thinking it should be 3 bolt holes, since there are 3 studs to hold it on? P/N: 44011AC020 might be correct...which is probably the MS 97055.

Nothing close...must be an east coaster? I tried to search on RockAuto, etc. too...must not be avl. west of the Mississippi! :-( See below...were your gaskets 2 or 3 bolts holes? Thanks

^Thanks, but as noted EDIT: I don't 'think' that's the right part.

Swapping a '96 2.2 into a '98 Forester. Edit: I was thinking I was looking for a 3 bolt-hole gasket- doesn't exist for the SINGLE-PORT heads. #1: Having trouble finding the SINGLE port exhaust gasket that goes between the y-pipe exhaust manifold and cylinder head. It's NOT the DUAL port.: 44022AA020>>> 44011AC030. EDIT found: Subaru part number should be: 44011AC020 EDIT - found: This should be correct (and 1/2 the price of dealer): MS 97055 Felpro. Like this: http://gallery.legacycentral.org/d/17545-2/DSCF4157.JPG This gasket was used on the '96-'98 EJ22 used in the Impreza, Legacy. Not found @ Autozone, NAPA, NOR THE LOCAL SUBIE Dealer. They ONLY showed the DUAL port for all years. WTH? #2: Also, the 2.2 has sat @ the local yard - in their shop - for @ last 3+ years ( I almost bought it 3 years ago for another project). Should I BLEED the HLAs before installing the engine? Thanks, Td

^...other than it's quite LOUD ! :-) I thought that the rod may end up thru the case rendering it scrap? But if we pull it b4 that happens, the block itself can still be rebuilt, correct? Thanks Td

Thanks for the feedback. The car was on a road trip and had been driven about 100 miles from home when the noise started. I bought it used in '11, fixed the head gasket and it was driven approx. 25K miles over the last 3 years before the knock started. IIRC the previous owner had already fixed the HG once before, so I don't know how bad/many times it was overheated.

This is the stock 2.5 / EJ25D. Is this ROD knock or valves? Code for Misfire on 2 cylinders, too Thanks

HuH? What is this "GFYB, MF!" ? I don't get it - and not sure I want to. I was NOT disrespecting you, if that's what you think. TD

EDIT: That's probably your issue.The AC cycling. And I'd bet it's just the O-rings where the metal lines connect to the compressor - unless it's gotten 'fried' due to overuse. Read up on here or over on Subaruoutback.org for info on the o-rings. Easy enough to do yourself, but you'd need to 'recapture' the freon to be legal. And 'subaru nut' is my 'rank' due to # of posts. My user name is 'wtdash', not that it matters, but just for future reference. :-) GL, TD

Hi, Not sure why others haven't jumped in.... Since the MPG seem OK, I'm not as confident in my suggestions...and i'm not that familiar w/the H6- but: - Tune ups? wires and plugs? EDIT: this uses coil packs on the plugs..they could still be the issue, but not sure how to 'check 'em'. - MAF sensor need cleaned (carefully! read up) - Vac line issues? Car is 12 years old so hoses get brittle - try another fuel station GL, Td

Yes...the intake and exhaust valves interfere as they are on separate cams. Depending on the piston protrusion above the deck they can also hit valves. You'll want to do the 'franken motor' search, but you get more hp/torque w/a 2.5 SHORT block and 2.2 heads. Putting 2.5 DOHC heads on any 2.2 - NA or Turbo - will reduce your CR. But w/a turbo block it's still good as it allows MORE boost. The EJ22T block w/EJ25D heads is a 7.7:1 CR; w/the EJ22e it's about 8.5:1. So, it's really only a WIN w/a turbo for either application. TD

+1 Also, I don't know your budget, but you might be getting into WRX>>STi territory w/your goals. You could get a hatch/wagon version, lift it, and - esp. w/an STi - you'd have much more performance potential - the power-adders are readily avl. WRX: TD

HI, I have some EJ22T experience and you'll have turbo lag to deal with. That might get in the way of any rock crawling. I'm running a bigger turbo and a 'Rob Tune d' EJ20G ECU and made about 225 hp/250 ft-lbs w/my '93 Legacy SS. This AT THE WHEELS - not crank. The EJ22T has SOHC low-flowing heads which get in the way too. If you put some DOHC heads on you should be closer to 250-275 HP. That's about MAX unless you go to a stand alone engine management and a bigger MAF. An NA ECU will NOT get you there. You CAN turbo the stock EJ22, but then you're running into reliability issues, and you'll want to be VERY careful about how much boost you run and a host of other variables. For what you're wanting to do an NA EJ22/EJ25 sounds best. Put some Delta cams in the 2.2 for a torque boost. I'd go look over on Legacy Central for more info. Be aware of your CV angles w/lotsa lift. At some point they'll get over-stressed - I don't know when. Note the rear suspension on the '09+ Forester changed on the rear, I believe - no longer compatible w/the early versions - Forester or Legacy. GL, TD

There was one in our local Pull and Save last fall. I got a few items off of it (seat heaters/switches and heated mirrors/switches). But missed out on the front skid plate - that was a rare piece of history. TD

Hi, Look on Cars101.com - here: http://www.cars101.com/subaru_archives.html = @ the bottom. Answers it all. Td

HI, Welcome to the USMB. BTW, it's best to start a NEW topic vs. 'bumping' a 7 year old one....but not a big deal. What RPM is your car running when it's 'creeping' forward? There is a procedure to obtain the CODEs in the transmission which the 16 flashes are indicating is present. This is separate from the Engine codes. Look on here to find out how for the '95-'98 models - I know how for the '90-'94, HERE, but likely different for your '98. You can also take it to a Tranny shop, but you're likely looking @ a min. Diagnostic charge. Once you get the codes you can post back here for advice....w/out the code we can't help much. GL, TD

You can use a TCU from any '90-'98 Legacy, I believe, as they appear to use the same 3 connectors. Td

Hi, Did you replace the fuel filter as part of your filter maintenance? Also, does it rev freely in Neutral/Park? GL, TD Off-topic but I can't imagine.. ...does this come w/extra passengers - to get out and push up hills??? Makes ~114HP and ~111 ft-lbs (slightly more than the old US EJ18) and it weighs ~3K lbs. 0-100 km = 12.6 secs. AWD/11.8 - FWD, BUT it gets combined 38+ MPG!

HI and Welcome to the USMB. And....What was the old trans doing that required its replacement? GL, TD

This is a cool fix...didn't know about it. Go from this: To this:
