Default jdm ej205 wrx engine HELP

So I spun a rod bearing in my 2005 wrx. I can buy a jdm wrx motor on ebay for about $1600 shipped to my door. Are the motors the same? Would it work with my ecu? Please help. Thanks! Here is a link: http://www.ebay.com/itm/171057163097?redirect=mobile

New ej205 Short Block is around 1800. That's the easier way to go.

It can add up quickly with short block, gaskets, head bolts, timing belt, etc. The seller said that you have to use your usdm intake manifold, crank sprocket, crank sensor, and I think that's it.

You'll have to replace the timing belt etc anyways on the used motor. The only thing you need to buy differently is the HG with the new SB and it's brand new and not some questionable condition used engine which you have to swap a bunch of stuff over to try and get working. Your call, time, and money.

http://www.jdmracingmotors.com/engin...or_AVCS_model_

This is the company i used and this is actually the motor i bought back in january. At the time I had a company in Minnesota install it and it was $1200 total, but put on tbe no cats, up pipe, short throw, pitch stop, gates racing timing belt, tomei timing belt guide, cobb ap, perrin intake, and a few other smaller mods. We left the avcs unplugged for the time being. But Im ordering a JDM ecu to run the avcs and had the jdm IM tgvs deleted and those are going in soon. This motor runs great when it gets good premium fuel, if all you have in yur area is 91 they dont like it. I run 93+ and soon will run e85 and a vf22.

I dont regret not getting a new short block, it would have been way more expensive in my opinion.

Your better off sticking with the same 1 you have if you wanna keep cost down. Youll have to change quite a bit to make the JDM work. Why not buold a hybrid and use a STi shortblock and re-machine your WRX heads, youll get more displacement and be able to make more power but not spend as much as a full sti longblock.

If you ever plan on reselling the car, it'll be an easier sale without the jdm or hybrid motor setup.

I agree with the mileage being possibly fudged, but to say JDM engines are crap? Dude really? lol lol lol

Now, would I buy a 8 to 10 year old engine that's been sitting in a warehouse or worse for god knows how long? Oh hell no!

When my 205 poops, I will build a hybrid from a new 257 block. They are dirt cheap! If done right, you get WAY more torque down low, and it will be just as reliable as any stock(ish) setup. It's all in the math kids! Don't be fooled by the idiots that try to cut corners on the hybrid engines. :-)

I question anyones sanity or reality when they purchase a used jdm engine slap it in and expect it to run.......especially when they dont tear it down first for inspection. You did not know the aproximate milage when you bought it.

Dude in the vendor for sale did that exactly what is mentioned above.........he is out over 3g's. Joint looked all pretty and **** on the outside.............but had rust all over the inside of the heads. Yea, he failed to inspect his **** too.

What is the facination with JDM EJ205
What is the kick lately with newbs wanting a JDM EJ205, not a 207 but a 205.
Why do people not figure out WHY THEY SPUN A BEARING BEFORE MOVING ON TO ANOTHER MOTOR TO BLOW UP.

Are the motors the same:rolleyes

A Jdm ej205 sells for less than half the going price of an ej207 and that is a huge factor. Many will want a little taste of that Jdm goodness at a price they can afford. Problem is that once they get the motors they are slapping them on without properly inspecting them. Then come the complications not having a proper ecu, no idea what to do about avcs, etc.
I purchased an ej207 and have 10,000 miles on it since the swap a little less than a year ago. Obviously Jdm engines aren't all crap but one must know what we are getting into before going forward

I just want a reliable motor that can handle my current mods. I am on a budget of about $2300. I found a brand new short block for $1650 shipped to my door. I believe the reason for the spun rod bearing was the stock oil pan. I decided to be stupid and do flat spins in the car, which im guessing made the oil go sideways in the pan and starve for oil. It didn't start knocking until after that, but my guess is that's what was the cause. I learned from my mistake and really just want the car to be a quick yet reliable car.

Dont make it true, as most cases those who blow up their 5mt do so before they even touch more displacement.

Bad driving, but good on ya for the research.

my 5mt has seen stock turbo, 18g, fp green and now 6266. It depends on how you drive.

Do you think I should be fine with stock internals if I get a new short block?

You should be fine up to 300 whp on stock internals on an ej205 and so should be the 5 speed trans. No clutch drops, never ever and shift like its made out of glass. I've been running my stock 5 speed with my stage 2 ej207. At a little over300 wheel torque it's been reliable, I'm civilized to it.
Is that a 205 short block you can get a deal on ?

Would the cost not be close if you sourced a used (good condition) 205 or 205 case halves...........grabed some sti rods, forged pistons, 79mm crank, acl bearings, etc......and not just go to 2.1l stroker?

The cost if you do it right should be pretty close to what a new shortblock is, the problem is you must account for the following (which is necessary anyway if a new sb goes in)

a. gaskets (full gasket kit)
b. spark plugs (depending on milage)
c. timing kit (depending on milage)
d. fluids

etc.........that **** adds up quick, along with whatever part breaks upon uninstall (sensors and ****)

If you just want to get back on the road new sb and done.......but you still need to account for the items listed above.

Don't forget head work is expensive, you don't slap on your tired cylinder heads on a fresh short block.
