I haven't opened it up yet, but supposedly the previous owner did just the pistons. No mention of boring or other upgrades which surprises me since all the Wiseco pistons need to be bored. I just hope they're the smaller size or that it has stock pistons to be honest.

The 22B's EJ22G was based on the EJ20K. It was Phase 2, unlike the EJ22T and did not have the oil squirters. I don't want the 22T to make a 22B clone, but rather just to say it's a 22 in a GC chassis, like the 22B. A built 22T should have the same or more potential that the 22B's 22G when it's all said.

id love to get my hands on a 22t block. I already have some newer 97mm JE's in my 22e block. that case and some upgraded rods and I'd see what this Borg can really do

Would be nice to see a 9180 on one.

I'm going to revive my own thread. Anyone seen a 22T with an 83mm crank? Is that too long a stroke for the displacement?

With suitable rods and pistons it is an option yes.

I havent seen too many do it though.

Is it cast in 'EJ22' on top of the block? Did they not have oil squirters either?

Yes it is.
No oil squiters, came with a phase 2 crank so you can drop a 207 crank in there without machining.

I definitely don't have 22G money and I don't see how it would help anything. I'm not entirely convinced you didn't post just to brag... Honestly, the extra trans bolts on the 22G are nice, but otherwise I'd prefer a 22T.

83mm cranks are almost all dual thrust machined so no need for a Phase 2 ready block or even thrust machining on a Phase 1. Any engine will likely require machining for clearance though. My bigger concern is clearing the oil squirters. I think the extra stroke will cause the piston skirt to interfere with them. Hence why I posted to ask if anyone has opinions on it.

Honestly, from those pics, it doesn't appear to have the phase 2 additional bolt holes.

Anway, I would still suggest going to the #5 main for the thrust bearing.

As for piston to squirter clearance, assuming you have some calipers that's a pretty straight forward math problem. If you're really that close, then obviously the solution gets trickier...or you 'just' plug them.

I would want to keep squirters. I also would rather build the EJ22 as an EJ22...maybe a 79mm stroker. If your goal is to make big torque, I'd do an 83mm on a sleeved EJ25 and run a 2.7x liter.

I think after a lot of back and forth, I've decided to run a 79mm thrust 5 crank and 98mm pistons. Should clear the squirters and give some decent bottom end while still giving good top end. With this size bore, I think I'm stuck with the D25 WRX heads, which will give a high CR but should flow fine after some porting. B25 STi heads have a larger chamber than the proposed cylinder bore so I don't think they would work.

Hopefully this combo will give a nice bottom end and quick spool.

Dude, just get some custom pistons. They're quite affordable and quick with JE...so long as you aren't doing a lot of 3D surfacing.

Run the D25 heads and just adjust your dish for your target CR.

i like my 97mm JE's they dropped right in at .0035 and are pretty quiet even cold. I think only wiseco make ej22 pistons for the 79mm crank though. I also think the wisecos are dished more to compensate for the longer stroke to keep CR down

The problem with Wiseco's 2.2 stroker pistons is they are designed for use with a phase 1 crank with 48mm journals and 131.6mm rods and the 25d heads.

I think if I wanted to do this I would ask JE to make me a 2.2 piston with a 30.7mm compression height that also uses newer rings. Their standard 22 pistons use older thicker ones.

JE slug next to ej22e piston. If you took 22e pistons out and gave them a slightly bigger ring gap, they handle 400whp just fine. But after a couple tear downs i could see scoring and even had a cracked landing from the rings binding

I would need to find a decent engine builder around Richmond, VA to be comfortable with that. Local machine shop does alright but not sure I'd trust them to spec everything out custom like that.

I don't think it takes a lot more than sending JE an email and saying "hi, I am building a subaru 2.2 stroker and would like a set of pistons for it that are 98mm and have a compression height of 30.7 and XXcc of dish."

Yeah, their pretty good and I know this combination has been done by JE before. I've ordered plenty of custom pistons and talking with Jeremy and Nick. Been using JE for over a decade at this point, mostly all custom orders.

You'll probably talk with Jeremy, so as stated, just tell them the bore, stroke, rod length and which heads/valve size you're using. They'll ask about cams too.

Wouldn't it make a difference if the block has been decked? And I'm not sure how to tell if it has.

If the block is decked to the factory limit (0.1mm), CR will not even increase by 0.1 point.

The allowance for machining on the head is larger though. If both are machined a lot you can always just go to a slightly thicker headgasket. So I would say these differences aren't a huge deal as far as specifying piston dish.

That's helpful. Thanks!

Yes, it would but it would have to be decked a large amount to make significant CR change on this low compression engine.

Beyond that, for timing sake, when you deck the block and heads, it's best for cam timing to try and offset the decked amount with a thicker gasket. I know hitting exacts isn't always an option. You can also use eccentric idler pulleys to correct the altered cam timing as well.

Just took apart my 20k mile 400whp ej22. All the bearings were worn almost the same. Main #5 being the worst. I don't think it was about to blow but there was excessive glitter in oil so I took it apart anyway. Im going to put blame on myself being a cheap ass and not line honing and reusing a crank that could have been polished better. The pan and everything was clean. Oil just kept comin out with glitter so it was just wearing quickly I guess
