This is just in the "thinking stage" as the idea is popping my head, but I was wondering if anybody has turbo'd their NA ej22 ? Not talking a turbo swap from a turbo'd car, but rather swapping a turbo in and maybe mixing parts to get it to work. I have a spare GT2554 sitting around (needs exhaust housing so can always swap on a Subaru style to use a factory manifold) that would be more than enough even if it only saw a max of 10 psi which I think would be OK with the compression ratio of the engine so long as 91-93 octane is used. I have some extra turbo stuff from the Saab so that'd be a start. What can the ej22 NA handle if boosted? 225-250 would be nice.

 

Just thinking out loud here, but I'd need:

 

-drain into oil pan 

-fuel pressure regulator?

-MAP sensor?

-Injectors?

-fuel pump?

-intercooler, piping (would run a FMIC and none of that top engine stuff)

-coolant lines to/from

-oil feed

-BOV (have a Bosch)

-support bracket for turbo

-proper exhaust manifold

-down pipe

-ECM flash or swap?

 

Would it be easier to swap most parts from a turbo'd (pre OBDII) cousin? Care to explain how you turbo'd yours? A GT25 on a FWD Saab was nothing but wheelspin, but on an AWD platform the extra early torque should make it scoot and a 7-8 cm exhaust housing should help it stay alive above 5k.

you should post this where I posted my turbo build questions in the turbo tech forum. I actually got help fast there. this area is for posting issue related questions.
