comparing the ez30 ecu to the 2.5i ecu. looks to be a much more complete swap then the eg33

the ez30 will allow me use all my factory fuel tank sensors, and the factory fuel pump controller, speed sensor, coolant temp gauge, fan relay controls, and the factory tach with a converter.

essentially rip out the eg33, install the ez30 merge the same wires i had merged with the eg33, then about 8 - 10 more wires. seems simple enough. now i have to find a good ez30 and harness/ecu

^^^ That's what 42 Autosports has been using for their EZ30D swaps. There are a couple either here or on RS25.com.

No affiliation with these folks, just saw the ad on ebay. 22hr left with no bids, JDM EZ30R for $799 (or $1500 buy it now with freight shipping included). That's a helluva deal!

Just in case the link doesn't work, it's item #390534195731.

Hi all,

So, I'm thinking about joining the "dark side", and dropping a ez30d into my bugeye. It will hopefully be powered by a ViPec V88 with a custom harness, and a few other "custom" touches. It will stay NA for a while, and eventually, maybe, get boosted. Im choosing the ez30d for its simplicity, and bombproofness. Im curious if the below post is true (I will pm 42 autosports as well for their input). I do plan on resealing/ replacing everything that I can before the motor is installed as well. I have read through this thread a few times trying to learn all that I can, but its a lot to take in. I have a fab guy that's pretty damn good as well. Any input is greatly appreciated!

Car already has a full ver. 8 drivetrain swap including six speed (spun bearing and siezed motor), 5x114, brembos, as well as almost every commercially available bolt on available.

I also realize that it might be cheaper to replace the motor thats in the car, but ive always said "when this motor goes, it'll probobly get a flat six." And I'm willing to wait (read: save up funds) and do it right. I also do have the resources at my disposal to do the swap. Ive done all the work on the car up to this point except re-tolerance the center diff in the six speed. And if most everything comes close to dropping right in, I dont think it will be too much trouble. Im just looking to find out exactly what im in for.

Thanks in advance!
Ben

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've been slowly but surely learning how to pull the engine apart. Got the block halves apart this evening - that was actually quite a bit easier than I expected. I haven't pulled the rods off the crank to look at their bearings yet, but I already found a rather obvious gouge in the front side of the thrust bearing.







I would say the rest of the main bearings look just fine, although I'm far from an expert on such things. They all feel smooth, no visible or tactile grooves, they've got uniform color (no spots worn through).

Hey, do any of you guys know how easy/possible it is to swap a 5MT or 6MT into a 2004 Outback with an EZ30D?

After getting my EZ30D all torn down a couple weeks ago, I met up with Homemade WRX / 3MI Racing to have him take a look at everything. While I've done a couple of complete engine swaps, and I've swapped heads before, I've never torn a block down completely like this, so I wanted to get some expert eyes on the parts to make sure everything was in good shape. He concurred that the crank looks fine, all the bearings (other than the thrust bearing I posted the pic of earlier) look fine. Pistons have some pretty significant wear on the skirts (again, see previous pics), and the cylinder walls have some glazing and some light vertical scratching. Basically, normal wear and tear, and nothing that would prevent doing a "normal" rebuild.

So, with that in mind, I just ordered a bunch of parts from Annapolis Subaru - 0.50mm over pistons, rings, rod and main bearings, and gasket & seal kit. Should have everything next week. Once I have the parts on hand I'll be delivering the block and rotating assembly to a machine shop to have them do the balancing and bore the cylinders. I'll also give them the heads just to clean them up ("clean them up" as in literally clean them, not "clean them up" as in porting).

My two EZ30D engines are at sea somewhere between Japan and China at the moment. I hope to have them here mid April so I can put one in my car and tear the other one down.

If you're looking for an EZ30R, check out this auction - http://www.ebay.com/itm/Subaru-Tribe...sories&vxp=mtr. Ends @ 1900 Pacific time on Sunday, 2/24. Right now the auction is at $15.50, and it doesn't say "Reserve Not Met". I don't know if that's a mistake on their part or what, but there's a chance for someone to get this engine for a steal!

(Hopefully I'm not ruining someone's secret by posting this here. )

Edit: 18 minutes left, it's at just over $300. Like I said, someone is getting that engine for a steal!

Another question: for mating an EZ30D and a 5MT or 6MT, what would need to happen tuning-wise? Would the H6 ECU (which is currently tuned for a 4EAT) need to be retuned, or replaced? Or does it even need to be modified at all?

Thanks

You don't have to alter the H6 ecu, but you need to fool the 4eAT ecu to think it is in neutral.
RS25.com had info on this, but it requires some digging.

Got the first batch of parts from Annapolis Subaru yesterday - pistons, bearings, gasket & seal kit. Piston rings were on a short backorder, so I should have those early next week.

I'll probably drop stuff off with the machine shop this Saturday.

Around $1100.

0.50mm over pistons (with pins, of course) - 6 x 12006AB860 (per Jackie @ Annapolis Subaru, there are different part numbers for '01-02 and '03-04 engines; I don't know why)
Ring set - 12033AB150
Main bearings - 12209AA400
Rod bearings - 12108AA850
Engine gasket & seal kit - 10105AA530
Valve cover seals - 13270AA104 and 13272AA104
Spark plug seals (for the valve covers) - 13293AA051

For some reason those last two aren't included in the gasket & seal kit. Maybe because they don't have to be replaced?

The gasket & seal kit doesn't include a parts list, so I just shot a PM to Jackie to see if she's got one she can send me. It has the head gaskets, intake manifold gaskets, exhaust manifold gaskets, oil pump and regulator gaskets, the magnet that sits on the bottom of the oil pan ( - they include that but not the valve cover seals?), front and rear main seals, throttle body gasket, coolant cross-over pipe gaskets, valve guides, and a whole bunch of o-rings.

I know why

The 01-02 engines have cams with mm more lift (10.1 mm intake, 9.6 mm exhaust) requiring the pistons to have very small valve pockets in the crown. The 03-04 engines have cams with less lift (9.8 mm intake, 9.3 mm exhaust) which allowed for completely flat pistons without valve pockets. Timing of both types of cams is the same.

I dunno... both the old pistons and the new pistons I have don't have any valve reliefs at all. They have a very slight dish in the center of the piston crown - may 25mm in diameter - but I wouldn't think that was for valve clearance.

Do you have an engine code from which those pistons came?
