The EJ205 was standard block for a WRX
EJ207 was the block used in a STI
They all have EJ20 written on them it's mainly the pistons and rods that vary on these i believe. I cannot recall if the EJ205 block was semi closed or not, i'm guessing it was a Open deckl block, where as the EJ207 is semiclosed for sure.
thing I was worried about was under the inlet manifold it said EJ20 but on th plates and paperwork it was a EJ205 so I was wondering if it had an engine swap!
Thanks guys for putting my mind to rest its not easy when you have never experienced a scooby before its all a bit different from BMW's like what Im used too
cheers u legends and joz can always rely on you mate for a great explanation!
As said, all 2.0 litre engines are EJ20 (the '20' for 2.0 litre)... then the rest of the code letters/numbers is code for MY, variant, etc, etc....
Check the driver's side black cam cover - it might still have the white sticky label intact. If you have the original cam cover, the label should have the correct full engine code printed on it, "EJ205.. blah...blah...".
I think the VIN plate on the passenger front turret has the full engine code too...
i have a 2002 wrx which on vin.plate says it is a ej205 engine is this different from the ej20 and if so what difference as my engine has blown and i need a replacement

The EJ205 is the non-STi engine from MY99>on, so presumably it's the same engine carried forward to the Bugeye WRX.
If it's the bottom end that's gone, then a replacement from a Hawkeye STi is a good, relatively cost effective, fix/upgrade, as it has stronger rods than the preceding years. Or you can fit Hawk STi rods and any New Age STi pistons into your existing block if it's salvagable. You'll also invariably need a new crank if a big end is shagged (regringing a Subaru crank is considered a no-no by most of the big guns on here).
Obviously if you do go "mixed and matched", then the CR has to be carefully worked out, so at to choose the correct thickness HGs. Also, as a matter of course, use STi-spec MLS HGs (or Cosworth, Cometic, etc.)

Hello everyone, I was looking for some info about the EJ20's and on the web I couldnt find the info I need, so I'm coming to see if anyone could help me out,
The thing is,
My Subaru Impreza, is a 2liter N/A 2011, EJ20 naturally aspirated ( automatic ), and I'd like to improve it's performance by a bit, acceleration and retake acceleration, I know that the engine can handle over 250 perhaps over 300HP, but I'm quite confortable with about 200-230HP, would be more agile than my mom's 3.0R Legacy so that would be enough for me,
But the problem is that are many ppl who says they can "do" a turbo kit for it, and I dislike the idea of doing something without engineering put on it, and as for the Subaru WRX or STi when using EJ20's I figger Subaru used alot of engineering to produce/fabricate that, so I'd like to use and standart kit for a WRX to mount on my EJ20,
The problem so far is that I can't find someone who knows about them, to check if is just switch the original parts and install the WRX kit, and work the ECU, or if there's any other difference I need to work on and make a different part or buy a model part for that switch,
The ECU I figger I need to use the same one because of the gearbox, maybe switch with a new WRX aut ECU's, but I'm thinking about using a Fueltech ECU, that would allow me to use several maps and perhaps chance a bit the performance while using the car and not requiring me to get to the garage to make such change,
But the WRX kit, and by that I mean the exhaust from the block to the turbine, the turbine, the intake to the compressor and from that to the intercooler, the admission from the intercooler to the block, and all peripherics required, is what is making me trouble sleeping about it, I'd try to the maximun to use original parts, for not look like tuning, I like the stealth mode of the original, and well, it is already a pretty over power look, at least here in Brazil,
So if anyone could answer me that, I'd be very much pleased,
Thank you for your time, and sorry about any mispells on my english xD
One thing I forgot to say/ask is about the diff over the EJ20 and the EJ25, some guy told me the exhaust pipes from the block to the turbine are pretty much the same from a EJ20 and a EJ25, so, would it be possible in case the changes are internal to the block, no idea if they are or not, to fit a EJ25 turbo kit from w WRX to the EJ20 of my car,
Just ask because is really easier to find an EJ25 from a wrx here than from a EJ20 wrx, they are coming to Brazil only at EJ25's from 2008 and up, and to get an WRX EJ20 kit I'd need an import or used/old one, and if need to go for an used I'd go for a newer one if possible,
Hey guys I’ve got a 98 forester gt had a blown ej205nwzke swapped engine for a ej205nxwbb have swapped manifold due to loom short and egr..changed over boost control solinoid end plug on engine loom....swapped crank gear and sensor and cam sensor car will crank over but not start fuel pump works seems to have spark at coil pack also I swapped the individual coils to an single as that suited my loom do I need to also swap the cam gear where the sensor plugs in ??any help to what I have missed thanks

Your EJ205NXWBB engine comes from a MY01 Automatic model, which as you have found out has individual coil packs as against the single inlet manifold mounted coil pack version of the earlier models.
Crank and cam sensors are the same for both model years,
Knock sensor is different.
Why would you need to change over boost solenoid plug?? as you would be retaining the old setup.
All you should really need to do is use just the "new" long engine block with all the original ancilliaries including engine loom, inlet manifold, turbo etc.

thanks for the information mate I was told to change the end plug on the manifold loom as it was the only one that didn’t plug straight in..the crank gear has different sensor points (teeth) on the back so thought maybe that was throwing out my timing??would the difference in knock sensor stop my car from starting?thanks again any information is greatly appreciated
a new-age crank gear will NOT work with an older style ECU...........
you can basically use the new style engine BUT swap your full inlet manifold, ancills, etc. over and ensure you are using the early style crank trigger
Yes the crankshaft sprocket changed for the 01 so changing it a good idea.
But so did a lot of other things. including the ECU
Knock sensor - probably a different impedance.as it changed when the new ECU's arrived.
Still not sure which engine loom you are using the old or the new??? If you were using the old there would be no need to change plugs.
What does this actually mean "have swapped manifold due to loom short and egr." ??
and in reply to my question "Why would you need to change over boost solenoid plug? you reply "I was told to change the end plug on the manifold loom" when the boost solenoid plug is part of the bulkhead loom not the engine loom??
The 98 engine didn't have Tumble generator valves, so using the new loom you would have extra wiring thats not needed also wiring for the individual coil packs.

car is running just had to swap cam gear just idling high think it’s a vaccum leak thanks for the help

EJ205 AND EJ20 DIFFERENCES?
