Default EJ205 AND EJ20 DIFFERENCES?

As above really!

Im need to know the differences between them as the info on my car says I should have a EJ205 engine although it says Ej20 on th block case

is this an engine swap or is this perfectly ok?

My car is a 1999 t plate turbo 2000 MY00

What Car have you got?

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.

Hope this helps...

Yeah, you have the correct EJ205 motor for your car.

As said, the EJ207 is the MY99/00 STi block... the EJ205 is for all other MY99/00 non-STi applications.

See Pat Herborn's - mapper extraordinaire - more comprehensive explanation of the Classic engines' coding:-

yea cheers guys!

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...

Is there a code stamped on the block? apart from just EJ20, basically can you tell its an STi bottom end without stripping it?

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,

Thanks
