"Japanese engine runs different cam profiles and variable cam timing. With the better octane fuel in Japan, the Japanese WRX runs much more timing advance, not so much "more boost". The engine is able to make more boost down low because of timing and cam factors, not the other way around. Drivability is much better as a result. Or, as a friend said of the low speed running of the Japanese WRX, "It feels like a V-8" in comparison to the US car."

"Again by way of comparison, the American car as a throttle than can only be described as 'wooly' to use the old British tuner expression. It does not want to go below 3000 rpm, and the motor just does not feel happy at all below 2000 rpm. The Japanese WRX runs on light throttle at 1500rpm, pulls cleanly and smartly from 2000 rpm and is making good power by 3000 rpm."

"In the EJ205 'world motor', Subaru engineers have made a turbocharged engine that runs more like normally aspirated engine below 3000 rpm with a transition range to 4000rpm where it behaves like a turbo motor. It has only the quality of materials internally needed to stay alive at modest power levels"

I'll take JDM
The G block is the bottom of the barrel. It made 220hp and was used mostly in Legacy's. It had HLA's and is an old Phase I block. Some were closed deck but that is meaningless at the HP levels they can handle with stock internals. There were some better G blocks RS/RA and early WRX engines. Finding one of these is rare. Finding a low mileage USDM is easy. Mike is comparing JDM EJ205 and STi EJ207 engines to the USDM EJ205, NOT THE EJ20G

Mike runs a EJ20G in his own car. i drove his car last month - hes got the 96 WRX EJ20G bone stock everything. TD05, cast pistons with HLA, Stock cat in downpipe with no muffler (double resonators). probably makes about 280 crank ps.

Comparing his car with my best friends 235 dynopac AWHP Ej205 (stock TD04, no cats, ecutech tune), the tuned EJ205 is faster. more responsive, better top end (6K+) etc. spools quicker etc.

Mikes car passes emmissions in Cali. a JDM EJ20G passes CALI SMOG. enough said about that.

his motor setup is bone stock. You can buy an entire front clip with the awesome 4.11 gear ratio gearbox for less than $2500 bucks. ive bought 2.

a EJ205 dropout with harness and trans intact should cost $2500. we all know that a tune setup shoudl cost $1500-2000. (full exhaust+ dyno time)

play the numbers. which is a better deal for the money?

when refering to G motors let's talk WRX only. im not intersted in a pos legacy 220 ps motor with a VF10. we're talking about a front cut of a 94-96 JDM wrx car, minimum power is 260 stock and they have closed decks.

perhaps im lucky, the first clip i got was a sti version 1 with 8.5:1 forged pistons (in my friends car - gearbox was in mine - for sale now), Currently a Sti-RA version 2 v-limited is sitting in my garage with EJ20G 8.5:1 forged with mechanical valvetrain like the later K motors.

Freak luck i suppose :P

Powerlabs has the later EJ20K motor in his car with the nicer heads. more raars for him.

the argument is $2500 vs $4000-4500. Of course the ej205 for $4000 has its benefits, but its just too much money to put my vote there. is a $4000 EJ205 faster than a $2500 EJ20G?? of course. but you are still suck with the total ****e 3.9 gearbox ratios for the USDM. THAT is undisputed.

obviously for big power you want a EJ207. when i have 8K to trash, ill sign up for the version 8 longblock. they are quite the nice.

EJ20K is a good motor too, ssteve - ill be hard pressed to be even close to yours with my OG RA, but im guessing you paid a pretty penny for your clip - $4K ++ right?

at least in my view of things, alot of us are sticking with modding the GC8 cars because they are inexpensive to pick up and swap out. supercar on the cheaps, tahts what this thread is all about.

given the time and proper blingage id join the GDA wagen and pick up a GDA shell to put baller parts on. GDA is a better chassis, everyone knows that. its simply in the descrepancy of weight / cash / power combination that the GC8 car shines.

Total tune on the cheaps. thats what this game is about.

I hope that doesn't include Noah. His is a bastard swap without ECU, and shouldn't count. But his bottom end did go bad real quick.

That aside, the Ej20G heads flow significantly better than the Ej205 ones. Personally I favor using a JDM engine with a USDM wiring harness and ECU for tuning. This is what will be done with my RS-RA engine...

Supermoose I agree that the early WRX EJ20g engine are nice units. They make up to 260hp stock. The fact that you found 2 early WRX clips for the price you did is very lucky.

I dont see where you are coming up with $2000 to tune a USDM engine. Up-pipe, pinks, vf22 and a reflash can be had for that price and you are at 260whp. That cant be done with a early WRX engine. Injectors are hard to find, engine management is a huge problem.

Last thing i want to do is start another JDM/USDM fight. Thats not what this thread is about. For the most part I am pro JDM. If i had to choose between a JDM EJ20g or a USDM i would choose the USDM, there are just too many advantages to it. JUST MY OPINION. You can make you own choice.

With that being said, I chose the JDM path. And yes I paid much more then 4k for it, but I got a complete car cut in 2 peices with 3k on it. It wasnt just the common clip. Plus at the time (2001) it was (still is) the best of the best. If I had to do it all over again I wouldnt change a thing.

word.

yours is a drivetrain to die for. perhaps the next time around ill grab one

i suppose my option of tuning a ej205 would be to go catless with good exhaust bits and an ECU tech, at least the way we did it it was about $2K.

ej205 is nice. i really like it when its setup nice. i just cant afford it.

also, i hate the USDM 5 speed gearbox more than anything, perhaps thats my bias against it. its utter poop in my head. i love short gears.

what turbine setup is yours running? how did you tune it?

when i bought my first STi version 1 clip they had a DCCD type RA on the same lot. besides for having a smashed corner, if i had 4K to drop at the time it would be in my car right now. having the rear bits is really nice - can you pm me info on how you went accross importing it?

I was running a VF22 on stock JDM ecu, no tune. That got me my 11.87 pass. I have sinced moved on and now I am running a rotated mount 20g and soon to be Hydra tuned.

A complete stand alone ECU. They have plug in kits for the Ver 5/6 STi and maybe other JDM engines.

Wow... I remember when the hot ticket was an AWD swap, and Mike @ SPD was REALLY cutting edge in attempting to fab up a wiring harness to put a JDM EJ20 into his old Impreza. Now, we're doing all the wiring in < a day. WOW! How far we've come!

Now all I have to do is find an extra $25k lying around for a 2001 RS and a wrecked 05 STi.

I'm sort of feeling the neglect running a GC/GF in the days of the GD/GG. My motor, however, is current tech and I have a huge pool to work with when it comes to engine parts and tuning. That is a great advantage. Being restricted to a stand-alone or piggyback would bother me. Mostly personal preference at that point.

My V7 was WAY out of tune for the conditions my car runs in. I would imagine the older cars are less susceptible to this, but it is a valid concern in my eyes. Can it be driven without much in the way of engine management? When you mod it, how many hoops do you have to jump through to take advantage of the power?

I'm sort of rehashing everything that has been said previously so I'll step back for awhile.

Hold on here don't start this BS of saying well both swaps cost about the same but with this this and this the USDM has as much if not more and is quicker than a STOCK EJ20G. I will tell you right now especially you vendors, you should all no better. How about we throw the VF22 and injectors on the G with a tune like the EJ205 then lets compare them shall we? You know good and well the G will spank that 205 like a red headed step child and ask for seconds. There are tons and tons of Gs running around Aomori prefecture with huge turbos an ECU tune and some upgraded injectors drag racing and running crazy on the twisties every weekend with no issues. And I mean turbos like the 3037 and T67 and the cars run fine. So before you start saying add this and that think about how you sound because thats like the SRT guys saying "Well the money I saved on not nuying an STi, I can mod my SRT and make it faster!" and that has to be the gayest crap I have ever heard!!!

is there a list of what the engine codes mean? ej20g, ej20t, ej207, etc.
where did they originate, which is considered most reliable with high boost, easiest to find, cheapest etc.
i want to swap an sti(ej257) in but i'm still considering jdm 2.0's. thanks for info!

Well some of the stickies will help. But things like most reliable at high boost is something that is different with each person you ask. Easiest to find would be the ej205 us wrx blocks and IMO the cheapest. Then the earlier jdm blocks and then the later, newer, blocks.

Mine is an EJ207DW1KE:
280HP@6500rpm, 260ft torque@4,000rpm, redline 8250rpm
... and it was still cheaper than any WRX engine I could find anywhere, fuel pump, wiring harness, STI radiator, etc all included.
Still think you'd go for USDM?
