Uhhhh thats a tough one because its not a simple swap. You would be better off with a complete wrecked donor car. Like a 02 wrx that still has a good engine and transmission in it. The 1.8L is a EJ18

full donor cars make it easy, err. easier. almost every chassis part on a 04 impreza wagon fit right onto my 01 impreza.

Dont expect too much more help here, I was going to post more info that is ACTUAL fact with links but Ill just keep it to my self at this rate of ass-hattery you continue with. You hate it here because likely all your* threads go this way. Go to youre local forum where you might get 2 b.s. responses to a topic like this!

I dont really like nasioc because 99% of responses are people flaming the original question, or snide comments about the op needing to search. then everyone else chimes in on unrelated information.

I've done a lot of searching here, all have about the same result. search my threads that i've started. there arent many.

my home forum isnt necessarily for oem turbo stuff. figured i was better off going to the big forum asking a simple question about oem turbo stuff. hence why i posted in factory 2.0 turbo drivetrain.

its like walking on eggshells around here.

JDM 207 heads flow 283 CFM
USDM 205 heads flow 250 CFM

If you put a 207 big port head on a 205 shortblock you would make 207 power levels. Like I said before all the power comes from the heads and the huge airflow increase. AVCS also helps to make more torque on the 207 vs 205

The 207 also has a better oil pump (12mm) vs the 205 (8-9mm cant remember off hand) so it is much better oiled at high RPM.
the power wouldnt last as long....the 207 is a semi closed deck block and teh 205 is open deck and the 207 wont pop nearly as soon from lifting when the block distorts a head or ovaling a cylinder out under high boost

the usdm 205(there IS a jdm 205) and jdm207 are totally different engines...they share a few parts, but they are totally different

more good info. i read about the edm/jdm ej205 kinda figured those would be identical to a usdm 205, being they're the same engine code.. thats a different topic tho.

so. the semi-closed deck block is a fact on the 207, makes sense for reliable power. which is what anyone would want.
thank you!

Well its nice knowing the My04 2.0L has more crank oiling for up top in the rpm range, but as always, the US didnt get the 207

How come? people are doing swaps with them in the US and passing inspections. So the 207 was probably a proven jdm motor. Why did Subaru re-invent it into a 205 for us mericans?

on a cast piston the casting line will be very noticeable, a forged piston is made in a way where there should be no casting lines because it's not made with 2 mold halves sealed together and liquid poured in

the jdm market had the ej205 very similar to ours

the 207 was the high perf motor

v.7 internals=forged

v.8 internals= Hypercast (don't ask me what that is exactly, even on the web there's very little, it's a medium between cast and forged)

base ej207 runs on a higher octane to achieve those power levels in Japan. that's why when you swap one here it's not recommended that you use the factory tune.

hypercast is probably the same way that weisco makes powersports pistons.

but according to lukeskywrx the rods on the v7 are just plain cast.

not sure on this, but I would assume hypercast is referring to hyper-eutectic cast pistons, as opposed to hypo-eutectic

I'm pretty sure the difference is the % silicone used

I have a JDM 207 v7 with a red intake manifold.

On the top of my intake above and behind the alternator there are 2 filled holes. One in front just above the red alternator lead and one on the topside of the manifold. What is behind them and can I drill and tap one or both to install sensors?

Thanks and sorry for hijacking this thread.

Depends on what version of the 207 and which feature you want to use from the 207

If you select the correct ej205 or ej207 for your application it becomes a relatively easy thing to swap.
There is lots of documentation on the subject here.
What year car are you wanting to swap a motor into ?
Do you want to use an accessport for tuning ?
