‘05 in the hand vs the ‘04 in the bush


 

?
I have a running ‘05 Impreza (manual transmission) that is mechanically complete but has high miles and questionable history. ?It belonged to a paddler.
I would really appreciate some input on the trouble and expense of working around the Throttle-by-Wire and immobilizer vs just getting another cheap old ‘04 or earlier Subaru 2.5L.
Also while we’re at it, is there value in doing the full installation and then removing the engine to rebuild it? ?Or should I go ahead and rebuild it and just watch my engine temperature? ?I’m gonna go through the cooling system regardless. ?But it seems like it would be less stressful if I was doing the shakedown with an engine that I’m not worried about cooking.
I kinda figure after doing the conversion, pulling the engine back out to rebuild/replace it won’t be that big of a deal. ?Except for the fact that I may not want to spend much more time up under a Vanagon.
Thanks in advance?

Scotty,
I did much of what you propose. My Subaru engine is a 2.5L pulled from a 2005 Outback with drive by wire. The 2005 ECU from the Subaru could not be used in the Vanagon. I had the harness built for me by Busaru and when that was done an Impreza ECU was modified to go with the harness. Worked perfectly.?

DRIVE BY WIRE: I solved?this problem when I decided to go with the SMALLCAR conversion kit. They offer components which make the?drive by wire conversion easy. Check their?web site. .?

I had my engine rebuilt before installation. It will save you a whole lot of hassle later. I opted NOT to use SmallCars clutch disc setup. There are bigger ones out there. I have an automatic?tranny but still wanted the bigger setup. Sorry, but at the moment I can't remember the vendor, but they were one of the regulars. BTW, if you observe standard breakin procedures? on the engine you should have no problems. Make sure you change the oil and filter frequently during early stages of run-in? on regular oil then later switch to oil recommended?by the book for the engine.?

Finally, I recommend SmallCars cast aluminum oil pan and their unique device for checking the oil level from the access hatch under the license plate. It is a clear flexible plastic tube that sometimes is a little fiddly but it sure beats the heck out of having to unload the rear of the van to gain access to the engine. You WILL have to do this to add oil., but not to just check your oil.?

I Hope this helps.

John

On both, it 6 - half a dozen decision

Maybe start with what you have in hand and if? 04 drops in your lap consider the decision then

Re rebuild, unless what you are putting in there has known issues, I'd say put it in as is and run it till it needs attention.

Thanks for the replies.

John-
The Small Car DBW kit just seems to ad components, when I’m really focused on simplifying.
Maybe I’m answering my own questions. ?A cable to the DBW pedal mounted in the back seems like a lot going on between my foot and the fuel injection.
What about the Immobilizer? ?Is the Subaru ignition switch mounted in the back somewhere too.
?
Andrew-
It seems like once I start in one of these directions, I’m sorta’ locked in unless I want to go back and start over. ?Am I wrong here?
Wiring harnesses are expensive and removing/replacing them sux.
?
Again, thanks (I’m really not trying to be argumentative. Just want to get a better understanding of what I’m about to dive into.) ?I do appreciate the feedback.?

Scotty, because?of the condition I was in at the time, I HIRED my engine installation so some of your questions I can't answer. The fellow that did mine though did a very good job. He own three himself and maintains them all. He guided me to SmallCar. that's what is in his three. So far as the pedal in the back over the engine for me it works great. Sorry, I can't answer your other two questions.

I mean, it’s really your call. Having done a few of these, I’m a fan of just doing it once and doing it right.?

That being said, I started with a 1992 OBD1 EJ22 swap and later went to a 2006 Impreza EJ253 with the drive by wire. The immobilizer wasn’t something that caused any issues. I had the harnesses done by AutoVentures for the EJ22 and Busaru for the EJ253. The OBD2 allows for a reflash or physical code killer, and I could be wrong but i don’t believe the immobilizer even comes into play at all.?

The Smallcar throttle cable to the DBW Subaru pedal in the engine compartment is what I did, and it works great. I believe the option of adding cruise control is easier in the DBW setup than an old school manual throttle body/accelerator pedal setup.?

What I did, for like $2500 was get an AVLS JDM EJ253 and used that as my engine, and used the USDM intake and wiring harness to run it. After a had a bad experience with an engine builder here in the US, I was hesitant to go with another rebuilt engine and I wanted a long block that hadn’t been opened up yet and messed with and had low miles. To me, a 50k mile factory Japanese built long block will allow for better long term reliability than an engine put together by some redneck “engine builder.”

My thought was, it would allow for easy engine replacement when this one gets tired. Just order up another JDM and swap it out in a day.?

Just my $0.02

Not sure how much more you want Scotty.
If I understand correctly your questions were these:
Install used engine:
is there value in doing the full installation and then removing the engine to rebuild it?
AND
What about the Immobilizer? ?Is the Subaru ignition switch mounted in the back somewhere too.

As to the first, you’ve gotten great feedback. ?It comes down to you picking a route and going with it. ?I’m weird but I have fun doing things like swapping out engines. ?You might not like the idea of dicking around with your installed engine. ?But it would seem to me that if you have a sound engine you should install it.

As to immobilizers and such, a quick call to pretty much any of the vendors will tell you whether you have to worry about this issue depending on the year of the engine you choose to drop in.

Please keep your questions clear and concise. ?If you do so it’s much easier for the collective brain trust here to help you out.
Good luck with your conversion.

Best,
Brent

Connor-
That helps. ?I appreciate all the above input but was hoping for some hands on, like you provided. ?Was worth far more than $0.02 to me.
Thank you!

Brent-
None more, really.?
And I sincerely apologize if I wasn’t clear and/or concise. ?
I’ll talk to a vendor or two next.
Thanks

Update:
I spoke with Jeff at AutoVentures.? He was quite helpful and is who I plan to send my wiring harness to.?
He likes the '05-'07 model years for conversions and recommended a RMW Drive-By-Wire throttle kit to reposition the pedal and keep the assembly under the dash.
So I'm going forward with the '05.
Thanks to all
