Default 2.35 Long rod build with ej22t fully closed deck block?

Plans are in motion for my 2.35 long rod build. I have an EJ22T short block, would it be better to do 99.5mm sleeves in that block and build it with an ej207 crank vs 99.5 sleeves in my stock ej257 block?

Unless you plan on installin darton sleeves in your EJ22T case you won't be getting 99.5mm pistons in it and if you where sleeving it it would matter what case you started with.

In the end it would essentially be the same for either block if you go with the same size sleeves, same crank and same rods.

The only Advantage here is the 2.2L has a fully closed deck with oil squirters (not sure if machining for sleeves eliminates the squirters though). If it does.... I would go with the 2.5L block but send it to Outfront motorsports to be fully closed after the sleeves are installed. The only disadvantage of the 2.2L is that it only uses 4 bellhousing bolts vs 8 on the 2.5L block.

So OP, it really comes down to what would be more cost effective if the 2.2L can retain the squirters after machining!

I'll have it looked into. I want to keep my STi motor whole and build separate heads and block.

I see to many built subaru motors fail, so I'm trying to make sure I build it the best cost effective way as possible. closed deck seems like the toughest way. oil enquirers should be fine.

They fail typically from user error, shortcuts in the build process or put together too loose. You can spend tens of thousands of dollars on parts and sill put it together wrong, miss shift, over rev, lack of oil..... ect. Most people out there dont want to tell the whole story as to why it failed, they blame the tuner, the builder or anyone else they can before they would ever say they miss shifted or over reved the piss out of an engine.

I plan to over rev it, looking for 9,000-9,500 rpms and ~30psi. Basically going for what I can get on pump gas. cosworth 280 cams, cosworth oil pump, acl bearings seem to be the way. I don't want to get into a build sheet but I'm pretty sure I have the parts list down. Just questioning the block part of the build.
