Not to start a debate but I've never heard of such a product but from an electrical engineering standpoint, all it is is a capacitor that holds a charge and uses it to even out the current. But looking at all the dyno pulls, the differences are mostly sporadic, so I personally don't think they have much affect. Maybe they'll allow electronics to draw less on the battery but I can't see how that would make much difference in the powertrain. Only one real way to find out though haha.

I would agree if the numbers weren't presented. A couple of ft-lbs or bhp at peak gained from an array of capacitors as small as what the Raizen employs in it's unit is a pretty big deal. The car is electronic, ECU & TCU included. Not only did I notice better stereo sound quality, but also diminished startup time and much smoother idling. No noticeable difference in the transmission shifting, but that is an entirely big unit. I was also able to crack the 30mpg hwy barrier where I could not before, with blown head gaskets.

I think it's definitely worth a shot if they aren't absurdly priced. I'll look around for one at some point when I have some money burning in my pocket haha

 

I don't know how the prices are now, but I think I paid something like $32 for mine.

Okay. Since I positively need my car for work, I have done some unholy things to the EJ25D to get it running and keep it running for as long as I possibly can. I also noticed a block heating unit in the reman block, and I was told that it was an option on all 2G's. I am interested because I have never seen than on anything other than GT's and Outbacks before.

 

Pics of current EJ25D:

Recently, we'd gotten a snowstorm and it wasn't so bad, but I thought I'd take pics anyway.

To avoid t-boning an out of control Jeep, I drove off the road to save us. Quite an embarrassing situation. Womp womp...

Just to show you a teaser as to what kind of performance I am expecting from the EJ22D, the intake cams are a dead giveaway. These suckers have a fair bit of lift. JDM heads, btw...

I was just looking at the pics of all of the 2nd gen Legacies you've had. I just bought one identical to the White '98 GT (so far I'm loving it and only 94K miles on it). I recall one of your first EJ22D builds when I joined here 3- 4 years ago- was that the car you installed it in?

I remember seeing you. Good to see a familiar around! Yes, the white GT Limited was indeed the Legacy that received the 22D. That engine taught me much and sent me on a ride for more knowledge on EJ22's and EJ22 hybrids. :)

Easy off is great,used that on my pistons too, the non bake stuff works great.

 

Where are the heads coming from a 25d? Wouldn't that be lower compression than a 22 and 25? What do you do about that?

 

The heads are coming from an EJ20D, which has the same size chambers as the EJ25D ('97-'99) @ 46.6cc. The block I am using has -3cc pistons and comes up almost .4mm under the deck. This allows me to use the thinnest head gaskets available for the EJ22 (0.8mm) to achieve a compression ratio of 10.6:1 when everything is said and done.

Nice progress! So tell me more about the cams in the "ej20d" heads you have?

Are any of the internals of the ej20k heads upgrades that can be used in ej25d heads besides the cams? Not sure where I got the karma from, but today I snagged a set of ej20k heads shipped from AUS for $225!!!

Stick with the EJ20K heads in full. Intake ports are massive compared to the EJ25D heads. EJ20D cams have huge intake lobes compared to the EJ25D lobes. They're basically N/A EJ20K/G heads but without the turbo grind the 20K exhaust cams have, and the sodium-filled exhaust valves (STi version). They have nearly the same exhaust cams as the EJ25D. I am expecting the EJ20D cams to top out around 7200-7500. 20K cams will go up to 7500-7800.

Discovered upon installing EJ25D big plenum intake manifold onto EJ22D. There is a sharp corner at the end of the left front runner that will not clear the 257 coolant crosspipe.

The EJ22D is being finished at this point. Now, I am cutting the EGR pipe in half for lengthening and checking odds and ends out.

Prepping for installation.

Ran into another block. The bracket from the power steering pump also doesn't clear the EJ257 coolant crossmember. Luckily, the power steering bracket is constructed in 2pc mode. Unbolt the rear 12mm bolts and it will fit just fine.

 

Engine is installed and running at this point. It pulls hard at 3500rpm+, and the 10.6:1 makes it have enough torque to move along in the city just fine for what it is. No stock EJ22E is this powerful and neither is any stock EJ221/2/3, so I am pleased. However, the cams top out at 7500rpm and the ECU has a 6500rpm cap and is learning the engine that it is dealing with. MPG is 34+ on the highway, which I am also pleased with. I haven't gone beyond 4k rpm yet to break in the new components, but from what I can tell, the hybrid has a fair bit of punch over any regular N/A SOHC EJ22.

Also to note: The sensor that plugs into the EJ257 coolant crosspipe is 3 pronged, while the sensor for the EJ25D crosspipe is 2 pronged plus another sensor.

 

To use the EJ257 sensor on older Phase 1 cars, you need longer wiring to reach the connector to the front of the pipe where the sensor is located (the Phase 1 sensors are located in the rear of the pipe). 2/3 wires are colored EXACTLY THE SAME. This makes it easy for wiring/splicing to be done or the project to be a success. I would get a foot of wiring and a connector from any 99+ Impreza, Forester, or Legacy and MAKE SURE it is a 3 prong.

Continued kudos.

My question is how did you get a front mount tstat housing.

I was thinking it was my eyesight for the longest, but no, there it is on the front of the block.
