As best I can make out, the faded remains of a sticker (?) on the timing chain cover say DAXA8B-03 024769.

On the block, the passenger side bellhousing area says R25847. The driver side bellhousing area says 25792 and U024769. Both halves say BBB 63 near the centerline where the halves come together.

DAXABB is the first 'batch' of EZ30D engines for the USDM market.

Here's a picture I found browsing through Google of that first EZ30D:



You can see the tiny pockets for the valves.

Huh, those are tiny - tiny to the point of, "Why bother?"

New pistons I've got definitely don't have those. Old pistons are pretty heavily carbon encrusted. I just scrubbed the hell out of one and didn't see any sign of those little pockets, but I also didn't manage to get all the carbon off, so they could just be hidden.

Information bump. Can anyone confirm whether the ez30r exhaust buckets are solid/shimless and if they are varying thickness? If so, is there an online parts number resource besides walking into the parts department and prying it out of the parts clerk? I don't want to take of lots of their time digging and the closest is around 150 miles. Searching with our own parts department at work can sometimes even get a little complicated. Thanks

Well, that only took about 4 or 5 weeks longer than expected. But, I finally dropped the stuff off at the machine shop today. It'll be late this week before he even has a chance to look at it, so I'm not sure when they'll be done with it. I'm not in any rush - haven't sourced a wiring harness yet or started figuring out harness merging yet, so the engine can wait.

Jackie emailed me the parts list, but even that has just generic names and/or sizes for the o-rings. This morning, before taking stuff to the machine shop, I went through and figured out where all the o-rings go. Here's the handy dandy list that Jackie sent me, along with my notes on the side.

Yes these are shimless (well mine are )
I will try ti find the link I used for parts ordering (its in the US )

True. I just edited my post to make it clear which variant those part numbers are for.

Thanks for the reply, that will be great. Marnix also had the p/n's for them from Subaru so I can get one twice shipped if necessary. Sucks I have to wait about 1.5 weeks to get just one. Does anyone have a 4.55mm to 4.60mm bucket I could buy or borrow so I can order the rest? I may be able to wait a few weeks for all of them, but having to order twice and set me back another month possibly is just crazy.

Anyone have one?

I wouldn't post in this thread, but I can't expect someone with the buckets to notice my WTB ads.

So my two JDM engines arrived some three weeks ago. I first stored them in my garage but received a phone call from a former Subaru dealer requesting an engine for a 2002 Outback H6 which suffered severe overheating. So I sold one engine and traded the overheated engine, which I have just finished disassembling.

I don't know the mileage of the engine but the bearings still look very good. The only real issue is that the cylinder bores are out of spec regarding roundness. So I guess I will have to order six oversize pistons, rings and a gasket set.

I will first have the heads checked for cracks and have them pressurized before I will have them rebuilt (thinking about using Supertech valves).

No huge progress to report on mine. I talked to the machine shop on Friday and I'm supposed to give him a call again tomorrow or Wednesday to get an update on assembling the short block. He's already cleaned up the heads, so I suppose I should swing by and pick them up at some point. I want to get the valve covers and the front timing cover powdercoated something bright and purty.

Still need to source a wiring harness. I think I'll head on over to www.car-part.com right now and do some searching!

Been a few years since I've posted in here, I've been going back and forth about trying to do a H6 swap, anyway, I'm working on *hopefully* being able to implement the stock ECU on a 30R swap.

In my spare time I have been going thru wiring diagrams, service manuals, the immobilizer manual, etc...

anyway..

I have the BIU, Combo Meter,Immobilizer Antenna, and ECM out of a wrecked 06 tribeca. Made sure to have the VIN for the car too so I can program the immobilizer when I am ready. At least this satisfies the Immobilizer system issue.

I have the BIU weeded down to the essentials
*power
*ground
*SSMIII communication
*ECM communication
*immobilizer interface
*CAN send/receive lines


After going thru the diagrams to find pins, connectors, what wire goes where, etc, I have labeled the wires so when I start to build the mini-harness for this I will be set.


I am merging this harness with an STi bulkhead harness for integration into the car, this ECM will only control the engine itself, the 04 STi ECM will still be installed for all of the other functions and Emissions Testing

Time for tons of wiring fun!



I am well aware of the obstacles with using this stock ECM, but figure I'll give it a shot on my project car as it's going to be apart anyway.

Not worried about programming the Immobilizer or anything since I am a tech at a Subaru dealer and have access to everything I need to program whatever setup I attempt.

I'm only $75 into this project, so if it doesn't work it's not a significant loss on my end.


If you guys have any input post up, I'm up for any extra info or tips, etc

EDIT: I have an ECM harness plug-in extension so I'm not going to hack up the original 04 sti bulkhead harness in this project

Mike

Got an extra 2007 Tribeca ECU if you or anybody here wants it. Pick up for free in Atlanta or $20 plus shipping if I gotta ship it. I mated the EZ30R engine to a 2008 WRX 5 speed. thread: Subaru EZ 30R mid engined track day car

Looks like you know what you are doing. One thing to note is the DBW throttles don't all have the same range...

EG33 is the most reliable/strongest engine, closely followed by the EZ30D. The EZ30R with active valve control system and active valve lift (Porsche VarioCam Plus system) is the least reliable due to the high oil flow demand of the valve lift system causing premature bearing failure.

the EG33 however uses the same type of belt that the EJ's do, making it longer/much harder to fit. it's not just a straight drop in like the EZ's - you need to move the rad etc.

I bought an OBX EZ30D header off ebay the other day, so that should show up early next week. I also ordered a couple cats from Summit to modify the header with cats, and a bigger/better 2-to-1 merge so it'll have a 3" outlet. My intention is to do a 3" exhaust all the way back.

Monday after work the block should start to get assembled at the machine shop. The shop is primarily a domestic shop, so the guy has never done one of these engines before. A bit unorthodox, perhaps, but he offered/asked if I wanted to help him assemble it. I wanted to do the assembly myself, but don't have all the tools, so I think this could work out quite nicely. His tools and general engine building expertise + my vast experience with this engine and my vested interest in ensuring it's done right hopefully = a successful rebuild. We'll see.

I still need to get off my ass and find a wiring harness from an EZ30 Outback. I've found a number of prospects via car-part.com, I just need to make the phone calls. The ECU I have is a 2001, and based on the wiring diagrams that Marnix sent me there are some differences from year to year, so hopefully I can get a 2001 harness.

It's relatively easy to adapt a later harness for an earlier ECU. I'm using a 03 Outback harness with VDC for my 99 JDM ECU Just a matter of removing everything that is not required and swapping one or two wires to the correct pin, 95% is correct.

I'm sure it can be done, but if I get a harness from the same year it's one less thing to worry about.

On a separate note, I found this pretty cool document on the Factory Five Racing forum (in a thread about using an H6 in their new 818 car). It's the Technician Reference Manual for the H6 engines - 9.3MB and over 100 pages. I've hardly scratched the surface of it yet, but it's got tons of great pictures, tips on working on the engine, etc.

so my ej251 took a gigantic crap on me aka rod knock so rather than throw in another ej that eventually will fail id rather have more power and reliability. so whats the big problems with swapping an ez30d? it will be going into a five speed 01 forester so with the exception of the suspension is basicly almost identical to a 01 rs engine ecu and wiring wise. i can conquer the radiator problems and but my biggest fear is the wiring? is it easier to merge the ej and ez harnesses or run a stand alone? does anyone do the wiring harness merge service for the ez30ds? also a parts list would be awesome thanks guys

Couldn't this be corrected by a better oil pump and/or modifying the intake to solid bucket and eliminating he variable lift? Or would that degrade the performance enough to make it not worthwhile?
