DOHCEJ22E1's 98 2.5GT Limited


Recommended Posts

Ah, well good man. I am glad it was an easy fix. I gotta get a downstream o2, and thenI should have gas mileage back haha. Good thing you are enjoying the effects of hard labor to get it to shape man. It is weird driving a quiet car tho isnt it? Thats why i had my exhaust done

 

I shall check those out when I am due for plugs. Keep going and you will be back at it soon bro.

I have to get an upstream O2 sensor & yes, it's VERY weird driving a quiet car. I'm contemplating a more wider exhaust piping. Right now, I'm tackling ALL of the maintenance stuff & then I'll be back to modifying in short order.

Ah I got ya. Yeah I did a full exhaust (think I said so earlier), and new front o2 but gas still isn't great. How's your milage

 

Well, it decreased some (about 32-33hwy) since I damaged the O2 sensors when I broke their TQ to get them off.

Updates:

My camera broke (again) so I'll post up pictures as soon as I can get a new one for the next few things that I do.

DOHC EJ22E block now has 11k+ miles while the 25D heads now have 175K+ miles.

Still runs smooth, despite it's small shortcomings.

 

Good.

New exhaust from catalytic converters back (Back to stock).

New Kartboy lightweight pulley that does it's job fairly well (smoother acceleration & "dipping" in & out of the power).

New transmission filter & fluid (all Subaru).

New 0 resistance NGK racing plugs (these are DAMN GOOD for making the engine more responsive ALL OVER).

 

Bad:

Piston slap on startup & it will have to be endured until I replace the engine with an advanced version.

Broke the upstream O2 sensor getting it off (PO135 & sluggish between 1800-2200 rpm).

MAP sensor doesn't work (I only figured it out after replacing the vacuum solenoid).

 

Plans:

New up stream O2 sensor.

New MAP sensor.

Sports brake kit next month guaranteed.

Detail & cleaning scheduled for next month.

Stainless lines & master cylinder brace coming in April.

Coilovers coming in June.

Various other suspension upgrades coming between July - October.

DOHC EJ222 build at the end of the year as a replacement for the current engine.

Piston slap really doesn't hurt anything. I've had my outback for around 10k miles now. It sounds like a skeleton masturbating in a filing cabinet, but it stops once it warms up.

 

Same here. Cold starts with a little piston slap, disappears on warm up. Had for as long as I can remember. IIRC, this is a common issue with the 2nd Gen boxer engines.

All & all, the EJ22 w/DOHC heads is a very efficient engine, especially when it is run past 2800rpm. Piston slap is a minor occurrence, but the current engine is just a "test mule" of sorts that displays my whole take on the DOHC EJ22E without a turbo. It does well & produces more power than a regular 22E but I'm looking for something with a little more "flavor" out of the N/A 2.2.

 

I planned for the mule to be turbo charged & may actually go through with it but that is not my end goal.

 

My "end" goal is pretty much a new goal for 2014:

 

222 short block.

222 head gaskets - 0.8mm

25D heads w/wiring & ECU.

25D crank gear.

25D water pump.

DOHC Phase 1 intake manifold spacers.

257 valve springs.

257 oil pump.

20D intake manifold.

Steel cam gears (the current composite gears have chips in them).

 

Digital readouts for everything you can imagine, connected to the engine & transmission, including the battery, mainly to keep an eye on efficiency & performance.

Maybe one day, I'll find a reason to trust the 2.5 enough to actually use it in any of my endeavors.

You should be using the 2.5 head gaskts with the DOHC heads. If you use the 2.2 head gaskets, the firing rings will be in the piston chambers. The STi headgaskets are the thinnest and best ones because they're MLS. This is how I've made all my 2.5 heads on 2.2 block hybrids.

I'm using the 222 gaskets because the gasket matches the bore @ 98mm, which I had to do for compression/fluid sealing. One thing I discovered when using the 222 head gasket was this...

...the 222 gasket matches the DOHC heads down to the coolant ports. It's like these heads were designed with the 2.2 in mind. The same with the 222. The pistons in that block have valve reliefs for the DOHC heads, which is why I have chosen it for my next engine build.

Alive & well. Aftermarket brake disc set coming soon.

amazing car!!! once I get a dent pulled in the trunk area im going to be painting mine white as well. How does the sunroof wind deflector mount? I'm assuming clips?

 

They install with 3M double sided tape:p Mine's been stuck on there since 2005 without any issue:cool:

That's not how the OEM subaru ones are, they have a nifty clip mechanism that holds them on.

 

This is true. Mine has these clips that you screw the wid deflector onto. I don't think it's even been touched since the day the first owner got it.

I do have an aftermarket deflector - but I also assumed they were all the same:redface:

 

Interesting - Would you had to have ordered it from the factory with the deflector? Cause mine had no such clips that I'm aware of.

The clips are part of the deflector assembly, not part of the car. So I assume if you buy a deflector from Subaru it'll come with all the related hardware.

Updates:

I still have not been able to locate the cause of the check engine light.

I wish that my OBD2 cable to my iPod didn't short out because that made life so easy.

The engine is still running smoothly despite of its piston slap & hasn't been burning almost ANY oil.

The vacuum lines are a bit shot though & I think there is a pin hole or tiny crack in one that goes into the fuel regulator.

I have lost a few mpg on the highway, it would seem. Maybe about 3. I now get 27city/32-33hwy.

This change happened because of the switch back to the stock exhaust system.

The ID piping width is too small, which is excellent for TQ & being quiet (sometimes, I can't even hear my car running!) but the wider piping before I had allowed for more midrange/top end power, not to mention I miss my rumble. Even the headers are louder then the exhaust!

I like the low-end being restored but I miss my rumble & higher mpgs (yes, 3 DOES matter!)

I had to cut the funding for mods this month because of the water, gas, & electric bills but next month, game on! I gotta start preparing her for Wicked Big Meet!
