a complete vehicle harness from an ez30d would go best into any impreza/forester/baja of same MY or older MY chassis(usually closest is easiest). and an outback H6 wagon swap is easier(cleaner with less work) to put into an impreza wagon/forester/baja than impreza sedan. since the harness's both have rear wipers, and a more plug and play fit. but... u may have extra plugs/wiring from sunroofs/heated seats or random interior option differences not found on imprezas that were on leggys. this is kinda common sense i guess once you dig into similar MY vehicles of different platforms. true lego power!

edit: theres a little length difference between them but, the legacy was a little longer, so you have some slack for re-routing purposes!

as stated above, newer MY=more headaches due to techno-sabotage installed @ the factory.

hey guys, I was wondering what you guys are running for the radiator/fan setup. I am most likey getting a custom pwr radiator, but the space is a little limited. I might have to go with slim fans. I just want to see what else everyone has or plan on doing about the issue.

Also here's a little update on my project. The engine is finally in the car, after almost a year.

I normally modify a GD wrx alloy radiator with two top tank outlets or use a Gen 3 EZ30D rad which is twice as thick as an EJ rad.

If you want to make life easy you should use a Link or Vipec on that.

The Hydra has already proven it's self finiky. I'm going with an AEM unit cause if the quality and support.

Most important thing is to find a unit that whoever will be tuning the car is cofortable with! Doesn't matter if it's the best or the worst if the tuner can't get the power out of it!

Not being a fanboy or anything , but I feel like im getting pretty good support from phil gabrow (element tuning). He's even tuning my car when he's in seattle (4-5 times a year). So hopefully all will go well on that front.

^^^Dom in Washington (frequents Idaho) know's them inside and out. He's been using them since before they were public. He was one of the original beta-testers and you'll find him/Maxwell Power on the Hydra tuner list.

Default ez30 into an 04 wrx

Sorry if someone already asked this. I scanned the thread and didn't see anything, but i mighta missed it. Anyways:

Any idea how hard it'd be to throw one of these ez30's into an 04 wrx? And what I would need, besides the ez30 itself? Thanks

Default Running EZ30D

A gallery chronicling most of my EZ30D-->98RS efforts here:
https://picasaweb.google.com/lbartik...eat=directlink

Did a wrx 5spd at the same time. Car was 4EAT.

I have pretty good schematic worked up for swapping into the earlier cars. Some of the missing info came from the 02WRX-into-98RS swap guide at RS25.com.

It's in, it runs, it leaks oil. (That's what they do I'm told.)
It has an exedy 3 puck and fidanza Al flywheel. Yes, it dies at every stoplight and there's no such thing as slipping the clutch.

Biggest problems:
ABS dead since it was A/T before (unsuccessfully tried grounding the A/T-ABS link wire).

CELs (anybody have ideas here?)
P1596 Automatic Transmission Diagnosis Input Signal Circuit High
P1698 Engine Torque Control Cut Signal Circuit Low Input

I think the car needs a good intake and a tune. Looks like the openECU project made some headway in the last few years. Anybody have experience?

It's running a '05 WRX catback, no cats, OBX headers. As it sits, it runs head-to-head with a stock 02 WRX wagon. Not enough to justify the complexity of the swap to me.

The simple answer is: not hard.

Are you talking ez30d or ez30r and oem engine management or standalone?

04WRX harness will merge pretty easy w/ EZ30d. Biggest difference I can see, the H6 doesn't use a fuel pump controller.

Beside the ECU and the main harness:

Sparkplugs, Any leaking cam seals, crank seals, valvecover gaskets (and sparkplug hole gaskets), timing cover silicone. Believe me, you don't want to work on that stuff after the engine is in. You can't. There is a leak behind the oil pump and timing chain on mine even after I did all those parts. I would never want to tear it down that far just for a leak anyway. Throw the motor away when it leaks too bad to deal with.

A clutch disc, pressure plate, TOB, flywheel, flywheel bolts, and starter that all match up to your current tranny.

H6 front engine mounts (nothing else out there yet and H4 is different).

All the belt-driven accessories from the H6. (has a 6rib belt) Or try to find a 5 rib belt the right length to run all your WRX accessories (untested theory). A/C is tricky, look close at your WRX compressor and the H6 one, I think the hoses are a lot different. I haven't been able to swap the clutch/pulley off my 98 compressor to try converting it to 6 rib yet. I know that all the '02 H6 lines won't bolt up to my '98 condensor, accumulator, or evaporator without adaptation.

Radiator - there's no easy solution but buying a plastic OEM h6 radiator and H6 upper hoses is probably the best place to start.

Pusher fans - nothing will fit between the radiator and engine anymore.

Radiator overflow tank - going to be a lot diff. than your wrx one.

H6 power steering pressure line, reservoir - (if you used the h6 pump). The wrx pump with the remote reservoir might work fine too with a pulley swap or belt swap. Uncharted territory.

A little bit of willingness to piece together the exhaust system. Impreza parts will generally mate up to the h6 header location or come real close. Notched trans x-member is necessary. Hopefully you have the two front O2 sensors from the H6 too. Rear O2 should be same as WRX. But the OBX headers are not made to work with a cat. So, a rear O2 simulator might be a good idea. Mine hasn't thrown a code yet. Car stinks though.

Intake - stock system is a little weird, need something to do the job though.

Tuning - H6 is speed-density (MAP) based so it needs help after throwing intake and exhaust mods at it. Haven't put the wideband on mine yet.

I'm going to use a standalone, most probably a sivecs.
The main challenge will be the avls and dual avcs......
Any experience with that ?

The variable lift is nothing more than a solenoid switched according to rpm. I switch them at 3200rpm as that gives the most seamless operation.

AVCS works the same as an EJ255. 36-2-2 crank plus 3 on each cam. If the ecu can't run it in closed loop then don't buy it, there are plenty around that can. I use Link/Vipec as it runs them like factory but you could also use an Adaptronic E420C or select 440 if you are on a budget. E420C is under $1k and can run dual avcs no problem. You would need to run it in waste spark and paired injection but that is not a deal breaker.

Link/Vipec is set up for quad avcs also. They seem to be ahead of the game when it comes to late model jap stuff.

oh and talking with my buddy Jake (konklr) last night, he said that the avls system defaults to the high lift profile. Basically when the solenoid is activated, it is pulling the pin so that it's on the low lift cam and when it's not charged, the pin is engaging the high lift lobe...

he wasn't saying this with 100% certainty but as he and I've been looking into it and him more so when he's bored at the dealership, I'll take his judgement on it. It also explains how so many swapped head SOHC RS guys are driving just fine without the solenoid being wired in.

Now to send a set to delta and make a bas ass street/race cam

The OEM radiator and trimmed hoses work all right. I bought a pair of cheapo ebay slim fans and they fit all right between the engine and radiator (it's tight though). For the overflow tank I'm just using a cheapo $8 universal one for now.

I'm very interested in what you're going to do about tuning, especially if you're using the stock ECU.

edit: regarding wiring: I had no prior experience and was able to merge the wiring harnesses okay as far as I can tell. There's a little bit of work in mimicking the AT signals to the TCM, but it's not a big deal.

I donít know if it is widely known, however there was an article published by MRT a few months ago about H6 cooling, they were looking at eg33, the same issue could well apply to the EZ30
In summary the bottom hose connection to the water pump was found to be too small at anything over low/medium revs, it was causing a severe restriction allowing an air pocket to develop at the pump, causing loss of coolant flow and consequent overheating.
The cure was found to be enlarging the pump inlet and bottom hose connection to 2"

The EG33 has always had a known hearing issue. Not sure if any of us knew that specific one, but in the SVX it's self it had bad air flow and thestock radiator sucked donkey nuts. That is good to know though since I need to redo all the front end of my motor.
As for the EZ30D's the phase 1's might have an issue but I would suspect of there were an issue the "R" Phase 2 had those issues resolved.
