Re: yellow wire from alternator

Warren Chapman
 

Mark,

The yellow wire from the round plug on the Subaru alternator is
spliced into one of (mine has two) the VW black "ignition on" wire
that come from the black junction box in the engine bay.

Thanks. Wow. Appreciate that.
Hey, a few questions sir.
Are you saying I need spacers on my syncro as well?
Or JUST for the non syncro applications? i have a reg van as well.
They seemed to fit fine on my syncro, and I looked at the suspension, but it was dark and of course I might have missed something, and I have no idea how they would fit with the suspension actually moving up and down.
The reason I ask this is that I have been told that the wheels fit the syncro with NO mod, but I learned quickly that I had to ream the hub a bit.
What is a spacer print?
I have also heard that the rear lugs have to be longer for the wheels to fit a non syncro van. Heard that porsche 911 studs work. Heard anything like that?
I would hate to have to press it new studs. Sounds likea lot of work...
Thanks again,
steve

You will need spacers too.I got the same wheels and used 5/16" thick alum.
spacers and it works clearing all suspension parts.Reaming out the center is
critical part and has to be precise for wheel balancing.I got spacer print and
if you need it can mail it to you. I got longer studs for rear hubs at Pep boys
at very reasonable price. Because they were bit larger diameter had to drill
larger holes in hub and pressed them in. The wheels proved to be very good and
with 215/75/15 tires lifted van for much better clearance.

Painted them silver with a clear coat after I reamed out
the center hub a bit to get it to clear all 4 wheels on my syncro. Then I
reamed out the inside wheel hub so they would clear the front flange on
the
syncro disk hub.
To get them to fit a non syncro van Ill have to ream out the center hubs

a full 2.5 inches.

Hi All,
My son Tom has after market mb allow wheels similar to what Nelson
described
a couple days ago. 5x112 bolt pattern, 7 inch rims with a 25 mm or 1 inch
off set. They fit his 86 2wd westy about as well as any that could be
engineered for it. He has m&s 215 75 15 LT tires and they turn 761
revolutions per mile, some 185 r 14 c tires on my double cab were 814,
his
old front tires LT 195 75 r 14 turned 834and rear 225 70 14 were 795. The
2.2L now turns 3700 rpm at a gps 70 mph . He has been touring the
northwest
the past couple of weeks and likes this set up. His words are more like
it
handles great, he also has a rear anti- sway bar.
I invested quite a lot of time with him on his wheels and tires and feel
his
set up with 25 mm offset is as good as you can get using the same wheels
all
around with no spacers. It is dead center between the outside wheel well
and
ball joint in front and has 1 inch of clearance at the trailing arms and
shocks in rear, enough so tire cables / chains will be fine if they are
tightened properly.
We looked at installing a taller 4th gear, Weddle has about 3 options to
choose from around $200. Larger wheels makes all gears taller and we
liked
that.
Tom's 2.2L has never had dying at a stop sign syndrome. Just the 33 (vss)
error code. We added a hall vss in place of the o2 counter and all is
happy
with the ecu. The check engine light stays off. However if we hook up
read
out jumper it will have 51 and 52 (neutral and parking brake) errors
logged.

Re: Final Drive Ratios

Darrell Boehler
 

Hi Larry,
We had some vss discussions last summer. I remember taking pictures but I don't think they are posted yet. On a 2wd 3 magnets
on the o2 counter shaft will be about right. We are using 4 with no problem. The o2 mileage counter spins at 800 revs per mile on a
2 wd. On a syncro you probably only want 2 magnets. Seems the legacy needs about 2k vss pulses per mile.
Ours is made similar to the Meyers brothers, except where they used a reed type contact we used the hall unit. The vss /
hall has given us no problems since install.

Darrell

Hi Leon,
We used a hall unit from webtronics.com, they only sell one. Digikey.com
sells hall units also, some of theirs are more sensitive and may be easier
to work with. We use 4 magnets just like Dick Meyer from Radio shack
catalog # 64-1895, attaching them to the vans o2 counter shaft with radio
shack quick drying epoxy 64-2313b. We get 4 pulses per revolution of the o2
counter shaft / or revolution of the left front wheel which ever way you
prefer to look at it.
It seems to us the vss along with the park, neutral switch, ac clutch
all seem to have an impact on engine idle. It idles very smooth at all
ranges and it varies the idle speed depending which switches or combination
of switches are active. I am waiting for a note from Dick Meyer on how to
wire up the park and neutral switches for best results. He has a handle on
them.

Darrell

ps. For those who want a quick run down. We will put some pictures and more
details on our web site and I will post here when we get them up. The hall
we used (ohn3133u) required passing the magnets within about .030 inch or
less of the hall unit front midsection. I tested / scoped the unit on
the bench using a drill to drive the unit. It has plenty of drive with just
the hall transistor (no driver transistor needed). On install we pick up 12
volts and ground at the fuel pump through a 5 amp inline fuse. The D+ wire
already at the o2 counter was lacking adequate power to drive the vss signal
on our van. (The 2.2L seems to have a very wimpy D+ signal). Other than
12v and ground the hall unit has an output pin that we took direct to the
ecu connector b58 pin11 or kep pin b11. We reset the ecu codes and have no
more 33 error type logged. As I mention in an earlier post we now have 51
and 52 error codes. Tom is traveling to Wisconsin to a further festival this
weekend, and the system will get a good long test under actual driving
conditions.

Hi Darrell,
I am interested in your vss and would like to know:
Is it one pulse/revolution? Which hall sensor you used?
Legacy used 2 vss, maybe you know how vehicle speed sensor helps ECU
control the engine

Re: WRX coming to US

[email protected]
 

I went to the LA Auto Show today and found a couple of interesting
tidbits I thought I'd share with the group.

A Subaru rep informed me that the Impreza WRX will be on display next
week at the show and should be on sale in the Spring. Engine specs
are rather impressive - 2.0 liter DOHC, turbo producing a whopping
227 hp at 6,000 rpm and 217 lb/ft of torque at 4,000 rpm. When our
2.2's wear out in a few years, this would be a nice alternative, eh??

Still, the Japanese market gets 290hp versions, which are sold nowhere
else. Though you won't hear about them, I was sent a factory power/torque
graph of theold-model Type RA engine, which I came within cooee of
ordering (turned it down when an SVX turned up).

I checked the new VW Eurovan out and was surprised at what I found.
Last year, the power output of the 2.8 liter VR6 was around 140 hp.
This year, they FINALLY got it right as power has jumped to 201 hp,
thats right 201. I had to read it about four or five times to be
sure.

Anyway I thought I'd relay this info to you all. I just had to take
a break from wiring hell to see the new cars for this year.

Hi Leon,

Did the 2.5L 1996 Impressa engine have a different head than the current

How do we actually find out the technical details of these later engines,
including curves?
If I had access to complete wiring diagrams, I could probably figure it out
between my knowledge and the engineers I use in my business and then draw a
composite diagram for the '90,'91 Vanagon to '99 2.5L Subaru for the group.
Griffin Motorwerke, the Berkeley, CA shop that has built Type 4 engines for
me in the past has excellent resouces for exhaust systems and custom
machining/construction. They should be able to coordinate the development
of a solid exhaust that is mounted correctly, runs clean and allows the
engine to breath freely. They are also an excellent source of info for
turbos, etc. These have been mostly applied to Jetta and Audi engines.

As far as i know the current 2.5l engine is the same as one from 97
Impreza GT with only diffrence that it is now again non-interference.The
power and torque figures are the same.Those from 96 should be avoided
due to cams and less power.
As of now KEP is not ready to offer late model engine conversion and it
would be
totaly to us to work it out and it can be pretty hard depending how we
can solve the trouble codes issue, new exhaust system, wiring etc etc
etc.The main issue being electrical. And, after all, it has to be
approved by CARB in our state.Lots of work!
I totaly agree with you that it would be a great engine to use even
though my 2.2 feels
stronger than 130hp it is rated at.

engine has noticeable more grunt than the earlier 2.5 engines. Was
this same engine in the 1997 Impreza? What is the factory designation
for the engine? The same in Japan as US? Does anyone know a factory
Subaru mechanic with access to the factory manuals and power graphs

a lot of these late 2.5L engines coming into the dismantler market in
the next few years. It would be good to work on this conversion.
Wiring, exhaust, cooling. This power would be a significant
improvement and parts and service would be available for a long time.
A mild turbo would extend the power down very low, which would be very
good for a Vanagon that has to work carrying people or gear.NelsonSF

Hello Nelson,
96 engines had diffrent(wrong) cams, less power and required premium fuel, not a good
choice.Current 2.5l engines are all sohc, dohc were not in USA.
I don't have access to any more info like curves etc. I don't have any Subi manuals

Hi Leon,

Did the 2.5L 1996 Impressa engine have a different head than the current
2.5L. DOHC? Does anyone know the factory designations for these engines?
How do we actually find out the technical details of these later engines,
including curves?
If I had access to complete wiring diagrams, I could probably figure it out
between my knowledge and the engineers I use in my business and then draw a
composite diagram for the '90,'91 Vanagon to '99 2.5L Subaru for the group.
Griffin Motorwerke, the Berkeley, CA shop that has built Type 4 engines for
me in the past has excellent resouces for exhaust systems and custom
machining/construction. They should be able to coordinate the development
of a solid exhaust that is mounted correctly, runs clean and allows the
engine to breath freely. They are also an excellent source of info for
turbos, etc. These have been mostly applied to Jetta and Audi engines.

As far as i know the current 2.5l engine is the same as one from 97
Impreza GT with only diffrence that it is now again non-interference.The
power and torque figures are the same.Those from 96 should be avoided
due to cams and less power.
As of now KEP is not ready to offer late model engine conversion and it
would be
totaly to us to work it out and it can be pretty hard depending how we
can solve the trouble codes issue, new exhaust system, wiring etc etc
etc.The main issue being electrical. And, after all, it has to be
approved by CARB in our state.Lots of work!
I totaly agree with you that it would be a great engine to use even
though my 2.2 feels
stronger than 130hp it is rated at.

engine has noticeable more grunt than the earlier 2.5 engines. Was
this same engine in the 1997 Impreza? What is the factory designation
for the engine? The same in Japan as US? Does anyone know a factory
Subaru mechanic with access to the factory manuals and power graphs
that we can scan and add to the library of info we have?There will be
a lot of these late 2.5L engines coming into the dismantler market in
the next few years. It would be good to work on this conversion.
Wiring, exhaust, cooling. This power would be a significant
improvement and parts and service would be available for a long time.
A mild turbo would extend the power down very low, which would be very
good for a Vanagon that has to work carrying people or gear.NelsonSF

It is widely available at most muffler shops and their website is very good.They
have
distributor shop search in all areas based on zip code.As far as i remember in
one shop they were selling 17724 for ab. $75 but you can call around for best
deal
Good luck

Thanks,

I will check those components as well as the O2 sensor based on your and
other emails. Thanks everyone for the suggestions.

I'll report my results back.

The "normal" error codes should be 33,51 and 52. Error codes 21 and 24
indicate
that those parts may be defective.The IAC aka air by-pass is important for
cold starts and ECT(code 21) is affecting the timing function of ECU by
sending confusing signals, so both may be adding to your problem.
Resetting codes will not solve the problems.Check both as shown in repair
manual and replace if defective.
My IAC is not working perfectly mechanicaly but electricaly is ok so i
don't get error codes.
KEP cat and muffler are fine and work better than stock VW.But more
restrictive exhaust shouldn't cause backfiring only less power at high
rpm.

Someone else mentioned more flow as a possible solution. Does anyone

Popping from the exhaust can be caused by several problems. I would look
for a restricted exhaust, a leaky exhaust, and improper timing. You
mentioned you are using the original cat and muffler. Make sure that
neither is plugged, nor leaky.

If you dare, you could try to remove the cat and muffler and drive it
around
the block just to see if the problem remains. If it does, then exhaust
isn't
the problem.

Re: '95 2.2 wiring

You may want to wait on the gear reductionstarter.? 18,000 miles after the installation and I'm still using the original 85 starter with no problem.? I thought I'd just use that one till it died & it hasn't!

Hi all,
I've been lurking for the past few months while working out of state but now I'm home and I have a huge pile of wires on my table in my garage as I start my conversion.? My problem is that I'm using a '95 engine and all wiring is different.? Hobert warned me about this but I decided I was smart enough to conquer it.
?
  • Has anyone found the ideal Subaru shop manual that shows wiring clearly?
  • Would the manual be?available on disk?
  • I would like to buy a used gear reduction starter so I don't have to buy an expensive new one.? If anyone has one they want to part with, let me know.
Thanks for your help,
Patrick

Backfring can be caused by valves not closing properly (tuliped heads,
worn
shims/cam lobes), burned valves/seats or exhaust leaks.

Had a Honda VT250 fitted with an XR500 engine (don't get me started on my
various repowers). It was popping on overrun, and proved to be a burned
valve. It was also a female dog to start, and prone to stalling, even
doing
so twice when throttling-off in FIFTH gear (thereby locking the back
wheel,
not fun).

A compression test can be used to show valve problems. Simple, cheap and
easy.

Expansion tank elimination

david wilhite
 

¿ªÔÆÌåÓý

Right now with my conversion, I've got the expansion tank set close to original location, just set a little to the driver's side.? It ended up being a tight fit putting the KEP air intake in place.? It seems it will work just fine although it will be a little annoying getting the air filter out.? I left it close to original so it would be close to the highest point on the engine hoping it would catch more air bubbles.? I am sure I will go with this for awhile.? Ultimately, I would like to eliminate the expansion tank.? I have a few thoughts on this, and would welcome additional input.
?
Since the radiator has plastic caps, brazing a new fitting for a standard radiator cap is out of the question.? This would have been ideal allowing the radiator to be filled at the front.? I have two ideas? I am exploring at this time.? One, is the idea of placing a threaded hose fitting in the place of the bleeder screw on the radiator.? From this I would run a short length of hose to a brass or aluminum (easy to machine) cylinder with another threaded hose fitting in the side of it.?? One end (the top), would have threads turned on it matching the VW expansion tank cap.? From the top end I would bore a void (kind of like a cup).? From the VW cap, I would run a length of hose into some sort of overflow tank sitting on the passenger side of the radiator.? The brass piece would act like a miniature expansion tank and could be located above the radiator at the highest point of the cooling system and should help on getting ai! r out of the coolant system.??Putting?water in would be a?slow process, because the fitting is so small.? The second idea is to again use a threaded hose fitting in place of the bleeder screw and run a hose to an inline pressure relief valve and then to a reservoir.? This would be a little simpler and smaller, but would not allow you to fill the radiator.? I have not researched the availability of a pressure relief valve that would work in the proper pressure range, yet I am sure that with all of the valves used in Industry there is bound to be one out there.
?
I still have a few questions I need to answer for myself, like where would I put a coolant level sensor and would I really need it?? I am sure there are other obstacles that I have not come across yet and I would welcome any input on this?
