My ‘98 Jetta TDI
2
Why Is My TDI Special?
3
It Doesn’t LOOK Special…
  • Externally, the car appears nearly stock.
4
Less Is More…
  • Externally, the car appears nearly stock.


  • All modifications and “goodies” are beneath the skin.
5
It Blends In…
  • This allows me to blend in while in traffic…


  • It is also less likely to attract thieves and vandals.
6
But What About INSIDE?
7
Melt the Hours Away…
  • I made it a point to make the car enjoyable to drive.
8
For My Listening Pleasure…
  • I installed a Pioneer CD/MP3 player (w/8-GB flash drive) and mounted a satellite radio receiver in the visor.  I have a seemingly endless music available during long road trips.
9
Is That All?
  • But there’s more to this interior than meets the eye:
10
Communications Suite…
  • I also installed my two-way radio suite, which includes a CB, a VHF/UHF ham radio, an “all-mode” HF/VHF/UHF ham radio, and a 1000-channel PC- programmable scanner.
11
Communications Suite…
  • The VHF/UHF ham radio is a tiny discontinued Yaesu FT-90R mobile radio.


  • I operate at 10-watts to avoid heat-related issues.  I use a 5-to-100 watt variable output amplifier when I need more power.
12
Communications Suite…
  • The remote mounted display fits perfectly in the “ashtray.”
13
Communications Suite…
  • The crown jewel of my setup is the Yaesu FT-857D.  It operates on HF, VHF, and UHF Amateur Radio Service bands at up to 100-watts.  It also operates in all modes, including AM, FM, CW, SSB, and digital modes.
14
Communications Suite…
  • Like the FT-90R, the FT-857D has a remote-mountable control panel.  I made a mounting tab that allowed me to put the quick release bracket on the front of the ashtray.  The position of both radios is nearly perfect.
15
Communications Suite…
  • The rest of the FT-857D is mounted in the trunk.  A grounding strap along with the antenna wire conduit runs between the trunk lid and trunk.  OH, look closely and you’ll see the 10” DEI Competition subwoofer.
16
Communications Suite…
  • My “antenna farm” features two VHF/UHF antennas, a CB antenna, and a Yaesu ATAS-120A “Active Tuning Antenna System” that changes its height based on my choice of operating frequency.
17
Communications Suite…
  • Since I park in a parking garage during the week, I also have a “lite” version with smaller antennas.  These antennas work well, but I do sacrifice a bit of performance for the sake of style and ceiling clearance.
18
Quickly Removed…
  • All equipment is quickly and easily stowed when the car is parked.  The full conversion takes about 10-15 seconds.
19
Almost…
  • One thing I cannot “stow” is my new gauge panel.  Wanting a “better” gauge panel, I fabricated this plate to hold my EGT and Boost gauges along with my Scan Gauge II.
20
Scan Gauge II…
  • The Scan Gauge II plugs into the OBD port and displays: MPGs, Fuel Rate, Battery Voltage, Coolant Temp, Intake Air Temp, Engine RPM, Speed, Manifold Pressure, Engine Load, and Throttle Position.  It also performs the following trip functions: Max Speed, Avg Speed, Max Coolant Temp, Max RPM, Driving Time, Driving Distance, Fuel Used, Trip MPG, Tank MPG, Distance to Empty, Time to Empty, and Fuel to Empty.
21
Navigation…
  • I was never a fan of navis until I started driving in Washington DC.  Now I’m convinced they’re a great part of driving.  This is a Garmin nuvi 650.
22
Where Did You Have the Electronics Work Done?
  • I installed all aftermarket electronics equipment myself at home.
  • I am an electronics technician in the Coast Guard; so it was easy.
  • Besides, the best way to get exactly what you want is to do it yourself…
  • And save the money that could’ve been spent on a hack job for something else.


23
Any Mechanical Mods?
24
Any Mechanical Mods?
  • Yes… But you wouldn’t know by looking…  ;-)
25
Look, Ma… No Exhaust!
  • I performed a “mufflerectomy” by replacing the cat-back with a  2.5-inch straight pipe…
26
Look, Ma… No Exhaust!
  • Result:  Better turbo response, a negligible increase in noise, and a savings of over $500 when compared to many aftermarket exhaust systems!
27
New Injectors…
  • I also added a set of KermaTDI.com Power Plus 502 Performance Injection Nozzles by Fratelli Bosio of Italy.
28
New Engine Programming…
  • Custom reprogramming
    by Rocketchip transformed the TDI’s driving experience.
29
New Engine Programming…
  • My older TDI features a socketed ECU that makes switching programs a snap.


  • Testing various programs is easy, too.


30
New Engine Programming…
  • Chip tuning offers the most dramatic performance upgrade.  With all mods combined, I measured 136-hp and 263-lb/ft to the wheels.  That’s 50-whp and 105-lb/ft over stock.
31
Suspension Upgrade…
32
Suspension Upgrade…
  • I upgraded the suspension system with the “Real Street Suspension” system by Shine Racing Service (SRS):
33
Suspension Upgrade…
  • I upgraded the suspension system with the “Real Street Suspension” system by Shine Racing Service (SRS):
    • Bilstein HD Struts


34
Suspension Upgrade…
  • I upgraded the suspension system with the “Real Street Suspension” system by Shine Racing Service (SRS):
    • Bilstein HD Struts
    • SRS springs (1” drop)


35
Suspension Upgrade…
  • I upgraded the suspension system with the “Real Street Suspension” system by Shine Racing Service (SRS):
    • Bilstein HD Struts
    • SRS Springs (1” drop)
    • SRS Swaybar (hides in torsion beam)


36
Suspension Upgrade…
  • Handling is tight and precise; but not rough.  The car is fairly neutral with a hint of understeer at the limit.
37
Smoking Tires = Lost Speed…
  • However, I put down more than enough torque to spin the inside wheel during aggressive cornering.


38
Extra Traction!
  • So I installed a Peloquin torque-biasing differential during a Sachs VR6 clutch upgrade.
39
Extra Traction!
  • Now ALL torque goes to the ground!


40
Miscellaneous Mods…
  • Since I travel a lot, I added a 1-1/4” hitch receiver.
41
Miscellaneous Mods…
  • It’s very handy for carrying bulky items, excess cargo, bicycles…
42
Miscellaneous Mods…
  • …and even towing an occasional load…
43
Miscellaneous Mods…
  • Finally, I added a set of polished VW LeCastellet factory alloys, optional on the B4 Passat.
44
Miscellaneous Mods…
  • I have over a dozen of these wheels.  Therefore, my look stays the same whether I’m on summer, winter, or race rubber.
45
Anything Cosmetic?
  • My current plan is to leave the car’s external appearance basically stock.


  • This will make it an unlikely “sleeper”


  • and perhaps allow me to continue showing the car in mild show classes.


  • Besides, it’s what’s inside that counts.


46
Isn’t That What We’re Taught As Children?
