just wondering if anyone has turboed there ej22 and if so what kind of reliable power/boost can it handle. also could i use the intercooler and turbo off of a wrx or sti on this engine.

You can make an up-pipe that comes off of the flange that connects the y-pipe to the first catalytic converter to feed the turbo, or you will have to notch/swap out your front crossmember with one out of a turbo car to clear the wrx headers and up-pipe. Oil feed, drain, and coolant hoses will all have to be custom configured. You can't run big boost (more than 10psi) because of the high compression ratio. But you can make decent real world performance gains.

 

Don't get caught up in "I want to make XXX horsepower" because you will push too far and blow the engine up. Set up the turbo, start with low boost and work your way up to something that has good power and a nice margin of safety.

 

Take a look at the "N/A engines with bolt-on forced induction" forum over on NASIOC, or 2.5rs websites.

perfect thanks and yeah i dont want to much power increase just a little i wasnt planning on running more than 8 psi anyway so some custom fab needs to be done then as well.
