Ej20 in my opinion. Subarus bread and butter engine for years. But tuning can always cut any engines life short!!!!

A lot of people will say that the EJ22 that was in the legacy turbo's is the strongest block. I think it has a semi-closed deck and some good internals to boot. But, if you look around, there's a lot of people putting out tons of power from USDM ej20's, JDM ej20's, Sti ej25's and there's a bunch of people that put out nice race blocks for decent prices such as Crawford. It all depends on how much power you want to make.

currently i have a 1.8 and boy it doesn't have power i cant even accel at 3rd gear so im guessing around 280hp or 300hp for now. Ive seen a closed deck ej20 push around 244hp and 235trq. I wouldn't mind having that much power for my car.

There are many USDM ej20's pushing about 300 whp. If you're looking for 280-300 hp at the crank, the USDM model should be plenty for you. Also, if you're swapping into a 93 Impreza, the stock WRX motor should do wonders on that car. Its a few hundred pounds lighter than an WRX if i remember correctly.

Strong doesnt mean reliable. A 12-15 year old engine isn't going to be more reliable than a new one. If reliability is your concern go with a complete swap from a newer car. Like within the last few years.

i think its about 800+ pounds lighter.
my cousin arnie told me to look for a wrx engine to drop in my L ive seen prices range to 4200+$ installed by supermoose with ecu and wire harness he said it was a closed deck, and there were others around 6000$ installed i just need a to find one but i want to change my tranny to. the wrx motor is just a bolt on right? i dont have to change my axles or my rear diff(planning to change that too so i can get the disc in the back).

you dont have to change the whole rear diff for discs, just the knuckles guy... the wrx motor is a direct mechanical bolt on (save for the x-member, na ones dont clear the turbo manifold) wiring is a whole different story

Check this out, http://sportcompactcarweb.com/tech/0403scc_hybrid/
If i remember right, this article says any transmission bolted to an EJ series motor will bolt to a WRX Engine. It even recommends keeping your tranny rather than use the WRX tranny. Again as stated about, wiring is another story.

yea i know but my transmission is weird, on 1st to 2nd, 2nd has a problem it has bump in the gear even on 3rd too. thats why i want to buy a whole new tranny. but i know that is going to cost alot more. do you have any suggestions?

reliability is a relative term.

things like prepping for install have alot to do with that. closed deck is cool, open deck is also cool.

all subaru motors are OEM designed for OEM reliability. as far as people talking about open deck or closed deck being more/less reliable for a day to day street car, they are just blowing smoke up your bum.

the old skool ej20g lived from 1989 to 1996 in its first form, and in a slightly revised layout untill 2001 in various markets. nothing wrong with that motor.

ej20K was in cars from vesion 3 era to version 4. also a good platform, but slightly harder to find replacement parts for (electronic parts, mech are interchange with G for 80% and 205/7 for the other 20%)

- I like the K alot, but it might be advisable to steer to the G instead because of the availibilty of spares.

ej205/7 in jdm version 5/6 is pretty expensive. very good, but you will pay the amount for a motorset only that you could get a G front clip for. if you need a gearbox already (its not ideal to run a NA gearbox with a turbo motorset for various reasons), then purchasing a full driveline might be ideal for you.

Kevin at JDM importers is a good guy to talk to for clips - they do alot of clips, although he supplies the real deal so you have to pay him properly for his services.

the usdm ej205 is a pretty good motor. its hampered with some things (TGV, million cats, OBD 100), but it is readily supported (85% of the fat pig owners have them), and things like replacement garbage snails (td04 / tmic) can be bought for chump change because peopel do not want to look at them. 300 crank is easily done (although you will spend a good amount of money on top of the motor to get there - full TBE+uppipe, Ecutec tune and dynotime for proper whatnots - ~$1200 or so average).

a dyno chart of a dyno tuned USDM wrx ($1500 on top of the ej205 itself) with 17psi of boost on stock td04 and 94 octane gas vs my jdm 1995 ej20G with a exhaust and crappy 91 octane street gas on 14 psi of boost (disregard the written notes- they were carried from differnt car)


usdm ej205 is penciled in, printed is JDM

people like to talk on this forum, alot of people do have quite a good amount of experiance on this forum, alot of people dont and talk anyways. pick and choose who's advice you listen to

a FWD GC8 weights about 2300 lbs. a stripper lightweight ej25 AWD can weigh in at 2500 lbs. a lightweight EJ20 turbo (aluminum bits and forgie wheels) car can weigh in sub 2600 lbs. your average 02+ WRX is 3050 or so. somemore, some less. id imagine there are few sub 2900 lbs, so at least you would have a 200 lb advantage minmum. its nice.


$1200 is quite a low price installed, $1200 is about what most places charge minimum for LABOR, you probably got a quote for $1200 some in parts.

some of the big swap shops are Garage tuning in so-cal, and LIC motorsports in NOR-cal. you might want to check out their websites for more finate numbers.

if you indeed like to rev high as your SN details, perhaps revist the dyno chart and think about what you would enjoy more.

the financial side of things.

ej205; ~$1500 for motorset (motor only, no gearbox - hopefully with wiring and ECU) budget another $150 or so for various bits ( FPC (fuel pimp controller), and bits such as fuel pump, filters etc etc.
$450 for a used turbo back exhaust and up pipe if lucky.

then you have wiring hell. 30 hours of labor, or $950 going rate for a send it off plug and play deal.

so you are looking ~$2000 for parts +950 elec conversion + $XXXX mechanical labor of install for a engine. easily a $4500 job.

EJ20G. ~$1200 for motorset with elecs,~450 for an exhaust, $100 for various things such as fuel pump/filters - no FPC needed, $950 of wiring labor, and mechanical labor.

so $1200+$450+100 misc is $1750 of parts. then the labor of the install and fitament.

the EJ205 in that form may throw CEL and require a accessport or ECUtek (budget ~$300 minimum), but in stock form with a TBE should put about 260 ps to the crank (that is my guestimate). the Ej20G as mine did put over 300PS to the crank.

so you would save ~$250 at least (more if you have to play the bobb axesport game with the usdm), and have ~40 more horsepower to begin with.

thats my opion on it.

perhaps thats why i have a JDM in my car

from what your opening post sounds like, your not worried about getting crazy hp numbers. Sounds like you want something daily driveable, with availibility of parts in case something happens down the line.. If thats the case.. The usdm wrx engine is the way to go.. Obviously parts, easy to get, and plentiful. Ability to make power, yes. Try to find an 02 or 03 engine, to avoid the 04+ open/closed loop fueling problem when adding performance parts without engine management.

Full USDM STI swap for 300 WHP with reliability. Hard, expensive- yes. More power and reliability than any 2.0L swap- yes. Worth the extra $$$- Depends on who you are and what you want.
