will be the last TiiCo update. My van has been sitting in my driveway
for over a year because of issues with getting the TiiCo registered
for street use in California. I do not want to go into a rant
session here, so if you have questions about the issues I've had,
feel free to use the feedback button above to shoot me an e-mail.
TiiCo registry will remain up, but I will be referring folks who
want to join the TiiCo list to join the one on YahooGroups...
those of you who might be wondering, I'm not getting rid of my
bus. Instead, I'm doing another motor swap. Check my Tech Info
area to see what I'm doing now...
you can see, it's been quite a while since my last update. I apologize
for that, but things have been very hectic for me the last few
months. I do have a few things to add today though. I have just
over 9,000 miles on the motor by now and have gotten a major issue
TiiCo motor has been running consistently warm/hot since I installed
it (212° F as read from the coolant temp sensor by VAG-COM).
I had one of the long plastic pipes split and cause a leak. While
the van was in the shop (my mechanic was able to get VW to warranty
the pipe because he had replaced it just over a year earlier)
I had him check the thermostat. He said that it was slightly corroded,
so I had him replace it. He installed a new thermostat and my
van is now running much cooler on average.
fan never came on on its own before. I had to turn it on via a
manual override switch. Even then, it didn't bring the temps down
any. Now, temp still climbs a bit when I get in stop & go
traffic, but the fan comes on and I can see the temp needle going
down! The temp still climbs to about 210° F before the fan kicks
on, so I'm going to install a lower temp fan switch. Thankfully,
the Golf/Jetta fan switches are interchangeable with our V'gon
switches, so I can get some rather low temp switches (Thanks to
the VW speed demons).
also installed a set of H&R springs to replace the aging stock
units. I don't suggest these springs if you do any off-road driving
because they are a bit on the stiff side and they drop the van
by about an inch and a half (The starting height of my van was
slightly lower as well because it is a '90 and therefore had the
lower Wolfsburg springs from the factory).
I installed the South African heavy duty trailer hitch. The install
only took 3 hours or so and a write up with pictures will be on
this site soon.
miles on the clock now and I'm generally satisfied with the new
motor. I still have that vibration buzz between 3600 and 4300
RPM, but I'm hoping that some more exhaust work will take care
of that. My mileage is a bit low compared to other convertees
and I'm getting a couple mixture fault codes in the ECU, but with
the help of my VAG-COM software, that should be taken care of
a trip to San Diego a few weeks ago, I had the van up to 90mph,
but didn't want to go past that. Not because of the motor (it
was only at about 4700 RPM), but because of the suspension. The
bus was getting a little squirrelly due to the springs that are
just about dead. Call me crazy, but once I get the suspension
sorted out, I'm going for triple digits.
a slightly saner note, I installed senders and gauges for oil
temp and oil pressure last week. I used VDO and was able to use
their "standard" aftermarket senders. Here's the big
bonus... if you look at the oil filter mount on the TiiCo motor,
there is the place where the oil dummy light switch is screwed
in. There are also two other allen head screws on that mount plate.
Unscrew them and you can screw the VDO senders right into them.
The temp sender is longer and goes in the hole closer to the firewall,
and the pressure sender goes in the other hole. My senders had
tapered threads, so they wouldn't screw in all the way, but the
pitch is correct for the holes. Very nice!
now got about 400 miles on the TiiCo engine, but due to the break-in
routine I'm following, I will not go over 3k RPM. The motor easily
has the same perceived performance as the original 2.1 liter motor.
After I get past the break-in period (at 500 miles I will do an
oil change and then be able to rev the motor to 4k RPM, which
is as high as I dared take the WBX. At 1000 miles I will do another
oil change, then be able to take advantage of the extra 1k+ RPM
the new motor has to offer), I'll really be able to see the advantages
of the new motor. With my automatic transmission, I was limited
to about 70 mph on the highway with the WBX because I didn't want
to rev the motor past 4k RPM for extended periods of time. With
the new motor I should have no worries about keeping it at 4500
or 5000 RPM for long trips (remember, the ECU limits the TiiCo
motor to 6300 RPM ).
