lulzcow Posted November 28, 2011 Share Posted November 28, 2011 I have the Phase I DOHC EJ25D with a EJ257 short block. I've also put in some 264 cams from Delta, Super Tech valve springs and retainers and some Cometic oversized head gaskets (until I change my pistons... If ever) Right now I'm using a TD04L turbo at roughly 14 psi and so far it's been absolutely fantastic. Noice. Link to comment Share on other sites More sharing options...

I Donated broknindarkagain Posted November 28, 2011 I Donated Share Posted November 28, 2011 EJ20R and EJ20K = same freaking engine. Only difference is the second turbo. For those in the US, the 20K is a better option than the 20R because you don't have to delete the second turbo on the 20K -broknindarkagain My Current Project - Click Here COME AND TAKE IT "The only thing necessary for the triumph of evil is for good men to do nothing."

I Donated broknindarkagain Posted November 29, 2011 I Donated Share Posted November 29, 2011 Not all EJ20s are semi-closed. Iknow for a fact that the 20R and 20K are open deck just like the 25D. The only closed deck block Subaru ever made was the turbo EJ22T in the 90-94 turbo Legacys.

mtcookson Posted November 29, 2011 Share Posted November 29, 2011 I know for sure the EJ205 in the 02 WRX is completely open deck. Just worked on one a couple weeks ago for a friend. It was giving us issues so I just gave him the EJ22 from my Legacy to do a hybrid. Should be even more fun now. Link to comment Share on other sites More sharing options...

I Donated broknindarkagain Posted November 29, 2011 I Donated Share Posted November 29, 2011 EJ22G is my favorite Subaru engine. It was what came in the 22Bs.

Kennyfvholla Posted November 29, 2011 Share Posted November 29, 2011 Yeah, and it was made out of the exact bottom end from the EJ22 from the Legacy SS and topped with my HLA heads. WAIT That's why I want it so badly. It's beyond sick, and building that engine is actually possible for me to do eventually. I actually have the heads and I'll have the block soon enough with all it's wiring and junk. I think I'll try to splice in an STi ECU.

I Donated broknindarkagain Posted November 29, 2011 I Donated Share Posted November 29, 2011 You can rev the piss out of the 20R and 20K too.

Kennyfvholla Posted November 29, 2011 Share Posted November 29, 2011 Apparently someone got there's to rev 11k rpm on a stock bottom end with just over 100k miles and only spun some sort of bearing... http://forums.nasioc.com/forums/showthread.php?t=448721 Link to comment Share on other sites More sharing options...
Kennyfvholla Posted November 29, 2011 Share Posted November 29, 2011 Even though it was only from a downshift.. ^^ It could still probably rev 9k if the heads were worked right Link to comment Share on other sites More sharing options...
DOHCEJ22E1 Posted November 29, 2011 Share Posted November 29, 2011 Does anyone know if there is a difference between the 96 2.5 pistons and the 97 to 99 2.5 pistons? I've looked at them but I can't see a difference... Yes, there are differences in both the pistons & heads. The piston tops are different & the head quench/compression areas are different. The 96 head quench areas match the bores & the 97+areas don't. The pistons are also different. The 96 has more of a high compression surface than the 97+, which I assume is the same as my 98 25D. This is one of the reasons why the 96 must be run on 91+ octane & anything after can use 87+. They're rare on the Legacy because our 96 GT's were the only year to ever come with them. But, they are the same cylinder head that was used on the 90's STi's with the 2.2 turbo as well. That's why they make such a great swap over to a 2.2 from the Legacy SS. The HLA heads to the 96 25D are bored to match that of the block. I would think that this would cause some sealing issues with the head gasket for the EJ22. Someone correct me if I am mistaken. I would also think that any head for the EJ22 would be bored for that block as well. The 97+ heads can be used as they have a "clover" shape to them, very much like some EJ20 heads do. This & the 96 heads/pistons, I've seen in person. Plus, solid lifters > HLAS is you're going to rev high. I would order an EJ20K from Japan and upgrade it to a VF43 turbo and stand alone ECU THIS. If you can. The 20K & 20R have a nice set of heads or more importantly, aggressive cams inside them that allow good high RPM fun. A Subaru technician explained to me that these cams are one of the most aggressive sets that Subaru produced. I have the Phase I DOHC EJ25D with a EJ257 short block. I've also put in some 264 cams from Delta, Super Tech valve springs and retainers and some Cometic oversized head gaskets (until I change my pistons... If ever) Right now I'm using a TD04L turbo at roughly 14 psi and so far it's been absolutely fantastic. Phenomenal. I bet that engine has some serious mid-range pull & high rpms. Is the short a completely stock 257? I do think that TD04 wouldn't suit an engine with that much gusto though. Just an opinion. Yeah, and it was made out of the exact bottom end from the EJ22 from the Legacy SS and topped with my HLA heads. Not exactly. The 22T from the past has oil squirters & the 22G does not. The 22G is also a 20G bored out while the 22T is it's own engine, not based on or bored from anything. The 22G is specific for the 22B & came with forged internals from the factory. It was built for serious duty. Link to comment Share on other sites More sharing options...

A Subaru technician explained to me that these cams are one of the most aggressive sets that Subaru produced. You couldn't be more right. The cams in the 20K/R are freaking awesome. My 20R was ass slow in lower RPMS, but was a MONSTER up top. I loved it. Here is a perfect example. My 20R vs a Vette.

mtcookson Posted November 29, 2011 Share Posted November 29, 2011 This & the 96 heads/pistons, I've seen in person. Plus, solid lifters > HLAS is you're going to rev high. Generally solid lifters also allow you to run substantially more aggressive cam profiles as well. They can ramp open sooner meaning more lift during opening and will have more lift during closing as well for even more power. After dealing with hydraulic lifters and hydraulic lash adjusters in my Nissan's I would definitely take solid lifters over hydraulic any day for performance applications (unless there's just simply too little room to adjust them periodically). For a DD hydraulic is the way to go. Link to comment Share on other sites More sharing options...

Hmmm I must have been looking at the wrong picture then. This makes complete sense now as to why the octane rating called for, is different. I've seen the two different head designs, and the clover leaf will up the compression from the HLA's 9.5:1 to 10.0:1, but it didn't make sense for that to be the reason you regular fuel could be used. I couldn't figure it out cuz the stupid pictures were wrong.. The HLA heads to the 96 25D are bored to match that of the block. I would think that this would cause some sealing issues with the head gasket for the EJ22. Someone correct me if I am mistaken. I would also think that any head for the EJ22 would be bored for that block as well. The 97+ heads can be used as they have a "clover" shape to them, very much like some EJ20 heads do. This & the 96 heads/pistons, I've seen in person. Plus, solid lifters > HLAS is you're going to rev high. All I know is that people have put HLA heads on EJ22 turbo bottom ends. I don't know how though, as I have yet to actually research it in depth. I had already planned to use solid lifters if I was going to want to rev over 7k rpm and make mostly top end power, but stay with the Hydraulics and design it to have mid range power and keep it a daily driver if I didn't end up getting another DD Subaru. I think I may have changed my mine about this in general though, as I HATE the clicking noise HLA's make with a passion... Not exactly. The 22T from the past has oil squirters & the 22G does not. The 22G is also a 20G bored out while the 22T is it's own engine, not based on or bored from anything. The 22G is specific for the 22B & came with forged internals from the factory. It was built for serious duty. Yeah, I shouldn't have use the word exactly. Especially since the heads are the same type, but designed differently from the factory (combustion chamber bore, intake/exhaust porting, and cams). I didn't realize that the EJ22G was just a bored out EJ20G, not a variant of the EJ22T. But that could actually be just as good since it's also a closed deck and does have forged internals. And doesn't an EJ20G have oil squirters? Wouldn't, in turn, the EJ22G have oil squirters? Honestly, if you modified the heads correctly and designed them after the EJ22G, and put them on the EJ22T (I believe the piston have to be changed for some reason that I've forgotten), upgraded the headers, up pipe, turbo, down pipe, exhaust, and tuning, this would create one kick ass motor.

eekay Posted November 30, 2011 Share Posted November 30, 2011 ej20k is open deck. you sure the 20g is close? Yup. Positive it's closed deck. This, of course, is not to be confused with a FULLY closed deck. EJ22 (or EJ22T as the USDM has unofficially named it) was the only fully closed deck EJ engine. I absolutely LOVE my EJ20G. However, I may be getting rid of it for yet another Phase I DOHC EJ25D and a sleeved EJ257 block. So, perhaps someone might get lucky! Otherwise, I'll be junking the EJ20G block for the sleeved EJ257 block. I just hate the part this engine... My 9.3 cups EJ22 makes me feel like my **** is 2.8 decimeters!
