how easy/difficult is it to put an ej82t into a '98 2.5RS?

do you mean ea82t or ej22t?

EA82. sorry, I was in a hurry.

how easy/difficult is it to put an ej82t into a '98 2.5RS?

 

why would you want to, it would be so underpowered, you wouldnt know what to do. just find a new ej25 and use that, or go with a ej20 or something.

 

just my $0.02

an ej22 is sooo much better

dont put a ea82 in a 2.5 rs. that would be uber under powered! if you want a turbo, go with a ej20T or something of the sort.

OK, I dont know ANYTHING about subarus, and we have an ea82t at my work, and its the only turbo subaru engine I can find for a good price. but we have like six ej22's. I dont know the engine coding, so I'm clueless. what would be your suggestions for a strong turbo motor thats decently priced?

go on ebay and look for "subaru engine" you will find many jdm turbo motors reasonably priced.

A lot of the stuff on ebay is a scam. not to mention, with a JDM motor, you dont get a garuntee that it was taken proper care of by its importer. we just got a car in work the other day that needed a new engine because it had an improperly-cared-for jdm engine in it that had formed a ring of rust inside one of the cylinders and caused blowby/scarring/what have you. so I'm weary about not knowing who I buy my engines from.

i have a jdm motor in my hatchback, its the best running motor in a sube i`ve ever seen!

I'm not saying they're all crap, I'd just like a warranty on it. still, what engine would you suggest?

Drive to Lynnwood, go to Japanese Engines, Inc (a JDM importer right off of HI-99) and see what they have and can get. They offer guarantees, and seem to be fairly reputable.

 

The EJ22 engine will be more powerful and reliable than a stock EA82T, and should be pretty close to a bolt-in. A WRX "clip" might be another option, but might be more than you want to spend.

 

What is so wrong with your EJ25 that you want to ditch it?

well, I've always found that a turbo engine is easier/less expensive to upgrade. thats mostly why I want a turbo engine.

check this out, a ea82 motor like mine will get you 80-90 horsepower. now, im not sure on a ea82T, but im sure its not a hole lot more. now, a ej22T would get you a lot more, dam near double the ea82's performance. but ej20T for the kill man, way way more power!!!

could you(or anyone) possibly elaborate as to what the numbers/letters mean in the engine codes? why does the power go up as the numbers go down? I always thought the numbers stood for the displacement?

also, I'm looking at this 2.5rs for sale, and it has the motor out of a '95 WRX, I cant remember the engine code, but is that a formidable engine?

ej25t=2.5 turbo

ej25=2.5

ej22=2.2

ej22t=2.2 turbo

ej20=2.0

ej20tt=2.0 twin turbo

er27=2.7 6 cylinder

ej33=3.3 6 cylinder

ea82=1.8

ea82t=1.8 turbo

ea81=1.8

ea81t=1.8 turbo

ea71=1.6

 

the horsepower really is not in order with the model #`s

thanks! you see, I come froma huge toyota backround, with a dabble in nissan as well. in nissan, the numbers signify the displacement of the engine: L28= 2.8 litre inline six, vg30= 3.0 litre v-six, rb26= 2.6 litre inline six. whereas, toyota engines use the number to signify the generation/technological advancement of the engine: 7m= 7th generation m-series engine(inline six) fount in mk3 supras& in cressidas, 4ag= 4th gen. ag series engine, found in ae86 corolla, and in the 1st gen MR2. when you combine two engines, you use certain aspects of the coding of both engines, the best example of which I can think of is the 7a-gze. using the block of the 7a-fe in the newer celicas, the head off of a 4a-gze, out of a sc'd 1st gen. MR2, and a sc that would be used on aformentioned MR2. combine those factors, and you get the 7a-gze. By the way, in toyota, a "z" after the dash means its sc'd, a "t" means turbo. now if someone explain to me the method behind the numbers in subaru codes, it seems that some represent the displacement, but I dont know about the others.

Up through the EA82, the Id was just that, an ID. Afterwards, you get an engine series code (ER/EJ/EG/EZ/EF) followed by a displacement signifier (27/18/20/22/25/20/33... and 12 for the Justy). Technically, after the series code and displacement identifier you will often get an identifier that tells something more about the engine: EJ22G (IIRC) is the official designation of the "EJ22T" that was mentioned earlier. Here, we use a lot of shorthand like EJ22T or EA82T, but these are not official engine designations.

aight. thanks a lot.

so, say I was buying a car w/ an ej20g in it, would that be the tt 2.0 motor?

The EJ20G, or the domestic turbo, with one turbo, would be easier to retrofit into an RS, as the TT interferes with the master cylinder and the brake booster.

 

If I was to swap in a turbo motor into a GC8 body, or a GF8 even, i'd stick with 3 of the USDM turbo engines. in no particular order.

 

EJ22T

EJ20T

EJ25T

 

The EJ22T is an older engine, but is arguably more robust, and can be stroked to larger displacements. Its found in early 90's legacys and stock W/O intercooler puts down 160/180 hp/Tq

 

The EJ20T, found in the USDM WRX, 227/217 W/stock intertcooler. I believe this engine can also be stroked.

 

The EJ25T is found in the STi, and all turboed non Impreza vehicles 2003+, although in non STi trim it generates 250/250 as opposed to the STi's 300/300.

 

If it was my choice, i'd probably go with the EJ22T, add an intercooler and a complete exhaust and an aftermarket engine management system, which would probably net around 250-300 horse if done correctly.

 

Honestly, your best bet would be to do some heavy searching over on Nasioc.com they are more able to answer your questions, however be sure to do your research first, or you will be flamed out of town.

the EJ20G is the old STI motor and the 22B i believe, if that 2.5RS has a 95 wrx motor in it it is most likely a EJ20G, which is debatedly the best suby motor ever designed and built........but everyone has their opinions. and the EJ series motors do not come in 3.3 litre, those are EG33's, also known as the SVX motor.

^cool, cuz I'm really thinking of buying it. its a '98 w/ a 2001 front, and a 95 sti motor. it also comes with all the parts neede to convert it to rhd, if I really wanted it to.
