Depending on what you already have, you could always just import a brand new ADM V8 EJ207 shortblock, which comes with factory forged pistons and rods - they're around $2600AUD (ie. HERE), but there are other places to source it a little cheaper too.

I am going to ask you if you're absolutely sure about the existance of the short block.
My tuner here in Long Island NY, works for a dealership and they also own a rally team. Their engines have always been V7 or V8.
He specializes in ordering JDM parts.

He told me that there were no pre-assembled short blocks from the factory, for 207. He told me that this is one of the downsides of owning a 207 swap.

Reading what I am reading in the built engine section, I tend to believe that there is nothing that compares to a factory assembled shortblock, reliabillity-wise, if you're intending to stay within the power that stock internals can handle.

So, I always thought, you're buying an ebay engine, the seller does not know what the original japanese owner did to that engine, yet you have to plunk down a sizeable amount of cash.

If something goes wrong, there is no short block to be replaced..

Now, with your info, this changes the story for me. I'm going to point my tuner to your link as well.

They are 100% genuine Subaru built shortblocks.
  1. I linked you to the short block on ebay
  2. that is the Jarvis Subaru Spares ebay store
  3. Jarvis Subaru are the biggest Subaru dealer in the South Australia
  4. Jarvis Subaru Spare's buys the shortblocks through Subaru Australia
  5. Jarvis Subaru is HERE and parts link is HERE if you want to call them directly

These come direct from Subaru and are specially built for the ADM market.

no problems at all. The cost to ship it to the US will determine overall value for you though. You may find that with shipping, the final cost could be more then buying a rebuilt EJ207 from a reputable US engine builder.

In AU it is a good option because shipping is free

Wow.. so much information. Vlad how much would i have to throw at him to get me a V8 207 long block? I was looking at the prices for the whole engine harness, tranny and front end for around 6000 grand but i might not want that much. I would love the 2.0 with a 6 speed from japan
As i do not want to reuse anything from the old 205 as far as internals and heads... my goal is for 350whp ish with a torque line.. instead of peak

and the deal with shortblocks is i still need to get heads

I thought that container shipping for a palletized item is not that expensive, I would even think it could be in the $500 range. I don't know if duty taxes are going to be applicable to your drivetrain.

Of course, the shipment would take several months to arrive and then there would be more shipping charges from the entry harbor to one's doorstep.

Oh I ship engines, transmissions, etc fairly often as my side income.... Have a world wide freight shipping company that hooks me up, as their VP is a Honda guy and likes for me to get ahold of front clips for him.

It's just currently my work schedule conflicts with normal living style and I'd rather be doing other things in the little bit of free time I have going at the moment.

So Im beginning to think the best bang per cost is just get a long block, with harness, ecu and just plug and play it

-Complete JDM V8 EJ207 Long Block with TMIC, turbo...the works
-ECU
-Wiring harness
-IA Performance AVCS wiring kit
-Gates timing belt w/ OEM tensioner and all pulleys
-OEM Water pump


that was a list earlier in this forum.. i think its complete.. i'll be running a ball bearing turbo naturally.

so your gonna swap the twinscroll for a larger single scroll? The vf37 that comes with the motor is a journal bearing turbo.

Here's one for you guys. Got the engine in, fired it up. Just letting it idle to check stuff (haven't loaded a base map yet, stock JDM ECU) and I noticed that my EGT's are in the 1100-1200's, and that my headers are glowing red. Immediately shut it down. Is this abnormal? It was smoking quite a bit as if the heatwrap material inside the heatshields were burning. Didn't have an oil or coolant burning smell.

^^^ hope someone knows whats going on, that possibly sounds like its running really lean. No cels? o2 in the bellmouth of the downpipe?

No CELs, runs smooth, O2 in the bellmouth. Kinda nerve racking. Will log a bit to see if the ECU is retarding the timing massively for some reason, or if it is a physical issue.

found a couple things, not sure how helpful any of them will be to you:

Quote:
[causes of high egt] In no particular order,
1 incorrect fuelling for load point (poor mapping)
2 incorrect ignition timing both too advanced and retarded can cause det, and high EGTs (poor mapping)
3 incorrect cooling both charge and high water temps.
4 bad cam timing.
5 restricted exhaust.
6 wrong octane fuel.
7 too much boost.

Thats all i can think of at the moment.
Quote:
ok i see there are a few people that still have questions about does a rich mixture cause HIGH EGT's well here are some answers.

In a very rich condition the exhaust gasses will be lower do to a number of factors. The biggest reason and most obvious will be the lack of air to complete the combustion process. The Flame front created by the Spark will simply die out...thus lower EGT's. Now also another point is the Fuel its self acts as a "heat mop" (Takes away energy as it evaporates) and pulls away heat from the combustion area. Plus the remaining CO (carbon monoxide) from a rich envionment effects this process as well, it will convert to CO2 and again lower EGT temps.

Now in a Lean Envionment there is more air (oxygen being the primary Oxidizer) to sustain the complete combustion process..thus causing temps to rise and peak. This complete burn of both fuel and its oxidizer will give you the highest EGT's (peak) but here within lies the problem...too much heat from long pulls might cause "pre-ignition" (combustion (normal burn) before the spark occurs..not to be confused with detonation (violent burn))..pre-ignition is caused by a hot surface (valve,cyc..ect)..Indication of this can be seen in high EGT's. Now the environment is just right for Detonation..high combustion chamber temps with air and fuel being compressed causes the Event known as Detonation...the rapid and violent burn of the fuel/air mixture. The flame front during this Event travels 5 to 25 times faster then the normal flame front and actually disrupts the normal air flow going out through the exhaust. You will actually see a slight decrease in EGT's during "Detonation" plus you will hear it and such.

so basicly higher EGT's temps cause "pre-ignition" which could cause "Detonation". so if this was your car would you be conserned about high EGT's. I will leave that up to you.
You might have better luck in the engine management section.

Also,

Quote:
They [jdm ECUs] need to be tuned. They run both a lot of timing and a lot of boost. I'm temporarily running an AccessECU stage 2 map on my V7, but using the STi boost mapping. Even with the detuned fuel and timing maps, the ECU wants to run too much boost for 91 octane.

Those solutions would make sense if i was driving. However this is at zero load, sitting in my garage idling. I haven't even taken it onto the street yet. Using 93 octane. But the idle timing in the maps is 12 degrees no matter what map I look at, really shouldn't be doing nearly 1100-1200 degrees EGT at idle....

^The JDM ECU is tuned for something like 98 octane. You will need to tune the ECU to run 93.

Yes, and already working with clark on getting a 93 octane map. However at idle, it really shouldn't be causing those kind of issues, especially since the idle base timing is exactly the same on a USDM WRX or a JDM STI, about 12 degrees...

you can totally run around on 93 octane with a JDM map if you stay out of boost. I agree at full load and boost the timing they run is ridiculous, however idling and cruising around maybe hitting 5-7lbs boost should be perfectly fine. So if his map hasn't been tweaked, is oem, it isn't the root of his issues.

btw, to compensate for the timing, those maps run extremely rich as well...like mid 9s!

I've never understood how people can say things like this with a straight face. You've just rationalized (in your head) how same peak HP, lower torque is a better engine.

ok, ive read through the whole thread and am still wondering two things..

- how much benefit would one get out of mating up an ej207 block with bored ej205 heads over just a full ej205 longblock? and would this be a superior setup to ej257 heads/207 block? 257 combustion chamber is bigger but would avcs not out-weigh that detriment?

- i realize this question is unfortunately relative to locale. but can an ej207 w jdm ecu pass emissions? whats it take to get one to be legal in US if all thats required is smog and ecu scan? i had thought it was a much bigger deal than the comments in this thread seem to indicate, very curious as to the details of what it takes..
