[Help! EJ22 SOHC dual port exhaust egr tapping?]

I probably have not done any 90 to 94 engines. It's rare that I use one of those for a swap since the availability is poor. Typically I'm buying 95 to 98 engines and often I have to use a manual transmission engine or a JDM engine if that's what I can get at the time. Having done over two dozen 2.5 to 2.2 swaps I've had to tap the EGR ports about half a dozen times and find a matching manifold. I haven't run into one yet that I wasn't able to drill/tap but it's possible they exist.

 

If I had that problem I would just put a JIC bung in the exhaust header and weld a stainless flex line to the EGR tube coming off the manifold. That's how a lot of manufactures (Nissan for example) do it from the factory anyway. Where there's a will there's a way.

Going off subject what headgasket did you use for your frankenmotor with Delta cams? Did you by chance see how much valve clearance you had? Also you use stock valve springs or aftermarket? Thanks

[Help! EJ22 SOHC dual port exhaust egr tapping?]

I've drilled and tapped quite a few of these.

 

First you drill through to the exhaust port with a 1/4" bit.

 

Then you measure the depth of an existing port (another head or a manifold port) and mark this depth on a 9/16" bit (IIRC) and drill to that depth. This is the critical operation that must be done to the right depth to avoid the water jacket.

 

Then you tap the hole with an M16 x 1.5 tap.

 

It's not that hard to do if you take your time. One of my engine suppliers will do it prior to shipping if you need EGR on one of their JDM engines.

What years did you do? And do you have pics because there is noway after looking at them closely you can drill and tap the egr port on 90-94 EJ22 (AMERICAN) dual port sohc heads. I didn't even drill into the exhaust port because i found the water jacket. And theres clearly noway it could be done.

I did this same swap on my 98. I routed the hose from the EGR valve into the intake manifold after the MAF. In tens of thousands of miles it never threw a CEL for anything.

 

Brillant! Never would have thought of that! Thanks appreciate the help!

[Help! EJ22 SOHC dual port exhaust egr tapping?]

have many many 2.2 heads if stuck

 

Would you ship them i wouldnt mind another set of dual port SOHC, how much you get for them? Thanks

[Help! EJ22 SOHC dual port exhaust egr tapping?]

They didn't mess the combustion chamber at all? Reason i ask being the bore size differing from EJ18 bore 87.9 to the EJ22 bore of 96.9? I guess i dont have or haven't seen cc info them. Port size all the same does anyone know from EJ18 to EJ22 dual ports?

[Help! EJ22 SOHC dual port exhaust egr tapping?]

Yea i think i may just put a pipe plug in the head and run the egr tube down to the header. So does anyone really know if this can done on american EJ22 dual port heads besides the magical year of 95 with auto?

[Help! EJ22 SOHC dual port exhaust egr tapping?]

Yea i was looking at that but didnt want to do that route cause my luck is horrible. Wouldnt it leak though, with the expansion of the aluminum and whatever pipe i use being different causing it to leak water? I guess i dont have a ej22 single port head with egr off at the moment to see if its casted in or they used a connecting pipe? Something ill look into. My plan was to start with a 5/16 bit go through to exhaust then go to 9/16 bit and tap with a M16x1.5 tap.

[Help! EJ22 SOHC dual port exhaust egr tapping?]

Ok heres what i have a 93 EJ22 with dual port heads going in a 97 legacy wagon. Yes i have the wire harness/intake to make it OB2, BUT i need a egr port in the 93 heads is this possible? Or is this tapping for egr just for JDM heads?

 

I started drilling with a 5/16 bit in drivers side exactly were a 96 EJ22 with single port exhaust has the egr tube, and i found a water jacket before i found exhaust port?

 

Help would be greatly appreciated! Thanks and happy holidays

[Bearings for front cv shafts]

It usually occurs 63 to 85 when you can really notice it but you can start feel it for a bit around 30-35mph. im kinda lost at what it could be so thats why i was maybe guess the bearings? and it did with subaru cv shafts as well. Any guess's on it?

[Bearings for front cv shafts]

New struts, brakes,tires, cv shafts, tires, and the wheel bearings seemed good and tie rods are also good so is the rack and pinion itself. And just the stub part seemed to move more then it should to me?

[Bearings for front cv shafts]

The o rings not leaking or the seal on the shaft. I get this slight shimmy/viberation back and forth on the steering wheel and its not the brakes cv shafts or the tires or outta balance tires. But i feel the wiggle on the output shafts are little more then what they should move and thats gotta be it?

[Bearings for front cv shafts]

hey i was wondering if anyone knew what is the proper procedure for tightening the front two bearings, or is there a sequence thing to them? Or how do i know got the correct distance between the gears inside the tranny? Any suggestions thanks

[New to subaru's obx header question]

Sweets thanks for the helpful information! is there anyway to clear that code so it doesnt keep the check engine light on or not so much?

[New to subaru's obx header question]

sweet thanks yea im not looking for much performance its a daily driver the oem exhaust is starting to get holes rusted in it. Would you know if you just use the obx resonator and a muffler at the end would that be enough back pressure to keep the check engine light off?

[New to subaru's obx header question]

I have a 97 legacy gt and i want to get a middle of the road header price wise. Due to the stock being rather beat. Anyways i am lookin at a obx header and it says its for 98 impreza rs with a 2.5 my legacy has a 2.5. Now will this fit my legacy? I dont see why it wouldnt but i like i said im kinda new to subarus any ideas thanks
