Default Reusing OEM main bearings?

I found a block i been looking for. 99-01 Ej22 with 85k on it. My current PH1 ej22 is showing some glitter in oil after a rough 20k miles at 400-450whp. So i'd like to ditch this old block and crank for something still true and fresh on a budget.

What i would like to do is split the EJ222 case, hone cylinders, re-ring my JE pistons, install my sti rods with new king rod bearings, inspect oem main bearings, and possibly botton it back up with the original mains since they are probably spot on.

Its not as easy to measure mains as it is rods, im still an ametuer. I imagine OEM mains can handle the power just fine, you never really hear about these motors blowing main bearings

I would not reuse them. $70 bucks will get you a new set of mains, you might as well replace them while the case is apart.

Both of my ej257 cases with 40K and 100k miles showed main bore out of round.

I would plan on reboring the main and getting new bearings.

I've refreshed motors where the main bearings looked absolutely perfect... and they went straight into the trash and I installed new ones.

Thanks y'all. That motor fell through so back to the planning board. I might just pick up a Ej208 and run it a bit while I stick up some new internals. Or I might just run my ej22 until she pops.

I should but its over, It's got osteoporosis and its getting a transplant. EJ208 in route, gonna run that 9.0:1 sucker stock for a bit on E85 while i pull apart the 2.2. I sort of suspect the heads, I been hearing a ticking noise lately from the right side but not enough to think it was anything more than injector tick.

Im somewhat excited about the H20B heads on this Ej208 though. They supposed have bigger ports for a non-avcs head and more lift than a standard S20 head but not quiet as big as a S20V head. If my 2.2 bottom end is still solid then i might swap heads, if not, im gonna build this ej20 bottom end

I've gotta ask, what is a ej208? I've never heard if it before.

Legacy GT "twin" turbo motor in Japan and other places besides US. Us US meatheads just want bigger so we get the 2.5. The EJ206/8 is basically an EJ205 with higher compression and two baby VF turbos. One boosts the engine quickly to 8ish psi an then the other takes over at WOT to get it up around 16psi. They make between 260 and 280ish HP depending on Auto or Manual transmission.

Since im single turbo, i just use the longblock. Saves coin and now i have a factory built ported head 9.0:1 compression ej205

there she is, and runs good too


heres my Ej22 bearings

Interesting. Looking those I'm thinking your case shifted due to a good bit of heat or your crank is slightly bent. Just for fun do you have the capabilities of checking the runout on the crank?

blocks still there with crank next to it so i could. Theres almost 0 wear on the thrust surfaces. Even though i have a HD pressure plate. I had ARP head studs in this block, torqued them to spec but they were extremely tight when i went to remove heads, so much so that i have to cheat the cheater
