JDM v7 STI spec-C

Default V7 motor pricing into an 04 USDM wrx

My hybrid motor failed me (well the shortblock i had in there was bad to begin with) so now im in search of a new motor

I ran the idea of just putting in a running v7 longblock

my question is this:
I can get a v7 Engine package from JDMRacingMotors for 4100 shipped to my door.

so i realise i need to do some wiring for the AVCS. I assume everything will just bolt up, as long as i run a JDM downpipe and the JDM ECU...

what are the other things i must do to make it "plug and play" into my usdm 04 wrx... any other costs? im just trying to guage how much this will ACTUALLY cost me to have the motor in my car and running.
thanks!

I am installing a v8 (well worth the extra $300 over a v7) and aside from the AVCS wiring the only other thing I am having on hand is new oil, oil filter, coolant, spark plugs (might as well when the engine is out, easiest subie spark plug change ever) and exhaust gaskets. The reason I need the gaskets is that I need to take it apart to weld a bung to tap an EGT gauge onto, and a WBO2 on the Downpipe. Other than that, you definitely need a tune. Clark Turner offers tunes for a very very reasonable price (around $150-175 I think was his price last I checked). To get the tune you will need a Tactrix Cable, if you can't find someone local with one than that can be another cost to be factored in.

actually i already have a tuner in mind (already paid him for my hybrid motor but that went before he could even touch it ) anywho, im guessing usdm wrx 2.0L sparkplugs would work just fine correct? and when u mention the oil filter, is it different than the usdm makes? i was asking what i HAD to do, aka AVCS... any other things i need to watch out for? a version 7 would be going into my 04wrx, and i know the 7s are for 02-03s so is it justthe headlights that have to be addressed for wiring?

You can reference the plugs from the old ones you remove. Version 8 are 1 step colder NGK #2667 or Denso ik22.

For you... well first start by getting a version 8, trust me... its worth it.

Drop the motor in
IA Performance AVCS Harness
Downpipe either version 9 for direct bolt on, extended version 7/8, or custom with IA Flange or a $1000 zero/sports or tomei twin scroll downpipe

Thats about it for you. Then I would rec. a gates timing belt, timing belt guide cosworth or tomei, plugs and then get a flash or base tune asap

Ive been through this all so just PM me with any questions

im not looking to push insane power, just 300, prolly just keep its stock other than turbo back...
and the v8 i know is nice- but its more expensive, and i need to find a modded downpipe.

V7 has forged internals and V8 does not. V7 will handle more power.....The V8 is twinscroll so you need to run a jdm dp with that and an jdm midpipe. If you go singlescroll then you can run any usdm exhaust you want. after driving my friends twinscroll evo i wish i went V8 too but then you will never sound like a subaru if that's what you want.......I got my v7 for $3600 motor only and got it put in and wired for $975.....

Wali is indeed a classy guy. However, make sure when you get the engine, double check all the part numbers to make absolutely sure it is a Spec-C RA. There is an excel spreadsheet laying around here somewhere... can't remember the link off the top of my head, but it has all the part numbers, and organized wonderfully.

funny u mention that, i JUST found that spread sheet...
engine code is: EJ207DW4ER (JDM STI LIMITED)
it has the vf30 turbo with A/C so its actually not the Type RA or S202, but the limited... same motor and internals, except the difference being its not a vf34.

I have just a few questions about the swap, do you use the JDM EJ207 engine harness or did you use the USDM EJ205 engine harness? I have a local tuner shop that is telling me that I need to use my EJ205 engine harness and not the JDM engine harness that came with my V8 EJ207. I was under the impression that the motor is a direct swap. That I use the JDM 207 harness and plug it into my USDM chassis harness and run the IA Performance AVCS harness to use the AVCS system and plug it all into the JDM ECU. Is this correct or am I missing something? I have tried to find a thread that goes over the swap but I have not had any luck. If any one can point me in the right direction that would be awesome.

Thanks

Tom

That's what I am planning- usdm harness with the jdm engine harness and plug it all in. Then use the ia performance kit for the avcs. That shld be it

What I have learned with the swap. Twinscroll HKS downpipes DO NOT work with 5-speed transmissions, haha. Other than that, things have been pretty simple...
