Ej22T block swap
Hey guys I have a 2002 5spd obs with the Ej253, I was wondering if I could drop in an Ej22t block with 257 internals (I know about the journal bearing) and some forged pistons and turbo the thing. Not looking to swap wrx heads etc as this is a daily and Id like to keep wiring to a minimal. My questions are
*Any piston recommendations, and what cr am I looking at with this setup.
*what em should I use, I was thinking emanage ultimate
*what injectors, 06+ wrx? Already have a walbro 255.
*Roughly what power am i looking at?
*Turbo choices, I have access to Vf11 and Td04, looking for low end power.
Sorry if this is a long post, I searched but could only find 22t block swaps with the 25d heads.

*Wiseco makes pistons for the 22L with 2.5 crank and rods. Anyone else you use will have to make them custom and you will need lots of into for them that you likely cant provide. So.... your option is wiseco! Compression ratio will be odd being you will have a 97mm bore with heads made for a 99mm bore. What the final compression would be, I have no clue. But again, you can buy different compression ratio pistons for that engine, its not just 1 set ratio, they have many choices.
*EM, just have it tuned on the stock ECU, many guys out there run the AVO kit on stock ECUs and just open source tune them with a good standalone EBCS.
*Injectors.... at minimum the stock light blue 420 WRX injectors would do the job but the 06+ 565's wouldn't hurt.
*Power, no clue, nobody can tell you! Not even a ballpark. There are so many variants and options you can do. Turbo selection, cams, CR, boost level and so on and so on.
*Turbo selection, stick with smaller if you want low end. But remember you wont have much of a top end where the real power is usually made.
-Another note here, you know about the thrust piston you say. But do you also know about the bellhousing bolts and PVC lines coming off the block that are different? Not to mention the custom head gaskets you will have to have made for this?? You are honestly way better off finding a good 257 short block and just leave it stock and swap it in. That 22 block is way more headache than you would want. The 257 will hold the power you are looking for which is going to be well under 300hp.
