EJ22D=153awhp. N/A. With room for more.

[DOHCEJ22E1]

Before I get started with this thread, I want to say that whoever said N/A EJ's couldn't produce significant power at low cost, or that N/A hybrids could not do so at low cost, will be enlightened a bit by this post. Even I once followed this folly of not paying attention to N/A EJ's and believing them to be low on potential. Never once did it occur to me to test the EJ22D's I built way back when. Curiosity got the better of me, and I tested my recent project out. $1,200 I put into rebuilding this engine, total.

 

My project consists of Phase 1 1997 EJ20D heads on a Phase 2 2000 EJ222 block using EJ222 head gaskets at 0.8mm thick, producing a compression ratio of 10.6:1. As everyone should be well aware of by now, Phase 1 heads of ANY kind are inferior to Phase 2 heads, so if Phase 2 guys are reading this, you will be thinking correctly. You CAN &will make more power than Phase 1. How you go about it depends on your initial approach to naturally aspirated power. I will focus on how I did it, and all readers can take it from there.

 

EJ22D powered 1996 Subaru Legacy LSi producing this power.

 

Also, I'd like to say that with 1997-1999 EJ25D heads on an EJ222 block, this is also theoretically possible WITH portwork and hotter cams. The chambers do not need to be touched for any reason at all. In fact, I will release the list of components that helped my EJ22 achieve such power. Some will not believe, but rest assured, without them, my EJ22D would have produced much lesser numbers without a doubt.

 

List of components used for EJ22D:

EJ20D heads, valves, and valve springs (1997).

EJ25D big plenum manifold (1996 LSi stock).

EJ25D wiring harness (1996 LSi stock).

EJ253 water pump (2006).

EJ222 block and head gaskets.

EJ205 oil pump (detailed).

EJ257 coolant crosspipe and sensor.

EJ257 timing assembly and extra roller.

EJ257 oil pan.

EJ257 Moroso oil pickup.

VMS lightweight crank pulley (1lbs).

Grimmspeed intake manifold spacers w/bolts.

Self milled heads via sanding.

Lightly ground intake ports.

Refreshened and seated valves.

4 extra straight pins for head gasket and head security (Str8 mod).

Custom head bolt torque sequence (2lbs tighter on the last 3 rules).

EGR disable.

Started with Dodge 420A coil, then upgraded to MSD 8239 (used for dyno run at ECS Performance), then further up to the Accel super coil for the SRT-4.

Early eBay UEL w/2.5in catback to unknown muffler (we'll call it the Noemi Spec C).

Raizin voltage stabilizer.

1997 Outback ECU (7x).

93 octane (USA).

 

End Result:

I've been following your threads for a while now and has been giving me idea's for something to do with my 96 ej22e in my garage, Keep up the great build threads.
