Re: Which engine for which Vanagon?
I'm finishing up a similar situation. I had installed an '03 2.5 into an
83.5 Westy, bought a real nice '90 Westy, got a 2.2, pulled the 2.5 out of
the older and installed it into the newer, installed the 2.2 into the
older. They both use Small Car conversion parts. The '90 will be my primary
camper, so the 165 HP 2.5 motor will get the most use.
If you, I'd put the 2.5 into the Synchro.

Which engine for which Vanagon?
Here's the dilemma: I bought an 86 weekender poptop several months ago with a 99 2.5 dohc engine with 44k miles mostly installed, and am still tinkering with finishing up the installation. Then last week I made a deal on a 2.2 engine (year unknown), wiring harness, control module, and KEP plate that a friend purchased from an estate. It was part of a large quantity of VW related items. No info was available on the 2.2 engine. I have a second Vanagon which is an 86 Westy Syncro with the original 2.1 VW engine. My question is this: Which engine would be best for which vehicle? Should I pull the 2.5 engine out of the Weekender, replace the head gaskets, even though it has only 44k miles, install it in the heavier Westy Syncro, and then install the 2.2 in the lighter Weekender? Or would this be alot of extra work for a minimal amount of difference? All thoughts would be greatly appreciated !!

Hi Dudley, We will need more info before we can comment. a) Are you using the ECU tach signal or a dual diode Signal to drive the tach? b) If you are using the ECU tach signal - was the 86 Vanagon tach modified or do you have a different tach?? c) If you are using the dual diode type signal - was the connection to the DOPS system disconnected. With this info someone may be able to give you some advice. Tom Burlington ON --- In subaruvanagon@..., Dudley Smith <dksmaui@...> wrote:
Hi Everybody
I'm a newbie with a 92' legacy 2.2 in a '86 Syncro. The conversion was done just over a year ago. So to paraphrase Dr McCoy- I'm a carpenter Jim not a mechanic- so here is the issue. The tachometer started acting funny. Will not go above 2000-2500 even at 70 mi/hr. used to be 4000+ rpm. The good thing is that it runs great. idle used to be 800-900rpm now 400rpm. Any ideas? Thanks and aloha

Re: last connections, questions about fuel system
If i understand your question correctly i'd advise using the larger
intake manifold fitting for your vanagon brake booster and the smaller
one for your vacuum feed(s) to the charcoal cannister. You can tee
off the line once connected to the smaller intake fitting in order to
feed both vanagon charcoal cannister lines. Or, as per the Kennedy
instructions you can splice into the vacuum line running from the
throttle body down into the subaru charcoal cannister plumbing (at
least that's pertinent for earlier subaru engines).
Here's a bit from my website to give you some pictures to reference -
for both the subaru cannister installation and for keeping your
vanagon cannister.

Re: Error code: throttle position sensor error on re-installed engine
David: I won't comment on the compatibility question cuz i'm just not
smart enough in that area.
I will say that i often remove the tps (after carefully marking its
adjustment location) in order to avoid damage by the engine lift
chain. You're right, it's right in a bad position to conflict with
the strap/chain that you use to heft it.

Error code: throttle position sensor error on re-installed engine
84 wesite manual transmission, ej22 -- 1990 wiring harness (automatic
transmission), 1994 engine (manual transmission). So the TPS is from
the 1990. This is a Subaru-Subaru engine swap, not a VW-Subaru swap,
so the harness was fine with the last engine. So I simply moved the
intake manifold (and all the associated wiring from the engine I was
removing) to this 94 engine, then put the engine in the van. I notice
that the TPS takes a beating on the cherry picker when I pull and
install the engine as that's where the chain rubs. I have the Haynes
troubleshooting instructions for this error, I was just wondering if
there is a conflict between the harness and the engine (I wouldn't
figure, but it doesn't hurt to ask). If it turns out I damaged the TPS
with the cherry picker, can I use the TSP from the 94 wiring harness
(are the 90-94 TPSs all the same??
Thanks,
David

Re: Code 49 - 1990 AFM and IAC wiring help?
Thanks Tom for the context - and thanks Kim, that is a brilliant suggestion- I made sure they are snapped on tight...
I just took a test-run to the bike shop and it stalled 3 times in under 2 miles! Necessity is also the mother of focused diagnosis, so I turned once again to the AFM connector plug. This time, I couldn't find a ground at the black/red center wire - No ground at all! So I rigged up a quick fix and Vroom - I made it home!
I'm hoping this was the problem all along - though I will feel dumb for not ruling this out first. I had a mysterious problem a few years back that Scott Daniels helped me diagnose as the fuel injector ground. I should have remembered the lesson to ALWAYS CHECK YOUR GROUNDS!!!
In the next few days I'll take another test drive to confirm, and will post the results for posterity.
Thanks again!

last connections, questions about fuel system
I have read through the files about the charcoal canister and fuel supply, but I think my engine is a little bit different. I am not totally sure so I figured yall nice folks will help me out. So, 02 2.5L sohc rs out of a impreza. oh I dont have the suby charcoal canister so vw she be for better or worse...
Fuel. top of the rail- supply
middle- return
bottom- white line from canister
on the intake manifold.
On the right hand side looking towards the van
bigger barbed line-
on the left a tiny barbed fitting-
Can I use the big right hand side for the brake booster and the left hand side little barbed fitting to the purple line? My mechanical manual for the engine says the big one is for the brake booster on a subaru, but its advised to use it for the purple line.
I'm getting close!! so far about half of my money has been spent on bandaids(duck tap), soap and shop towels. Hopefully soon I'll be spending all the money on gas.

Re: Best Engine 85 Vanagon
re But others on this list say the 2.5 is another
inevitable wasserleaker how so ? granted I have seen some subaru engines with head gasket issues .. though it's nothing like waterboxers. the power curve / torque curve is what leans me toward subaur engines .. plus I'd rather not to go to a ford dealer for a part . where I am , all the conscious, non-violent peaceful people drive subaru's. at the other end of the valley all the pro-military types drive big american pick up trucks. For me there is a demographic factor too. plus a nice wide powerband is very nice ..just like the stock engine has ..wide power band, just lots more of it.

Re: Best Engine 85 Vanagon
I've seen both set ups. One of the things I love about the Bostig Zetecs, is how much room there is in the engine compartment. That inline ford sits up right (not slanted over like VW inline 4 conversions), and that leaves a LOT of room.
One of the things I like about Subaru conversions is they just seem so right for the Vanagon. Flat fours are nice and torquey beasts, and these are real jewels of engines.

This list is mostly about problems, go thru the archives and see how many folks are complaining about leaking heads in the last few years. I suspect that what you will find is that there WAS a problem with 2.5 head gaskets years ago. Years ago. The new improved head gaskets fixed it, years ago. I wonder where this old information keeps coming from? Who is saying "inevitable"? Rob becida@...

Re: Code 49 - 1990 AFM and IAC wiring help?
Something simple to check is the connectors to the engine harness. I had similar symptoms on my SVX powered Westy. I couldn't figure it out and paid (a lot) to have a shop diagnose it. After replacing a lot of parts, they finally found the engine harness connectors were not properly snapped together.

Careful here. even the though the alternator make look the same, compare it to the old one VERY carefully. The mounting holes may have a slightly different offset that will mean the belt won't fit right.
