Quantum Syncro + 2.0 L Audi TD, project for sale...

[jackbombay]

Here is a pic of my engine bay which was vacated today by the gasser that used to live there, Anyone want to buy a 5 cylinder Gasser?


  Here is a pic of the 2.0 L 5 banger Audi TD that will take its place  


  Maybe 2 weeks to have it in the car, I need a new clutch and the flywheel needs resurfacing, plus there are a few other fissues to work out, battey needs to go somewhere else, fuel tank filler neck needs to be replaced with Diesel sized one, fuel line/fuel pump removal...

sweet... AWD TD... i love it.

To give it its full name: :shock:  QAWD TD :shock:

 :mrgreen: Sounds like a  dyslexic HiFi Television; but a Bang & Olufsen to those that know :mrgreen:

Jack,
I've pulled the prime mover from my Quantum TD and stripped it to a husk. If you are short any little bits and pieces, let me know.
By the way, -- v. cool project

That is SO right!

   I've got most of the Quantum bits I need, but there are a couple bits I need for the Audi motor that are difficult to locate.

  There is a female threaded fitting on the vaccum pump that is about 3/4 of an inch, the other end needs to be barbed for the large vac line that runs to the brake booster :?  

   I also need a similar fitting, but smaller for where boost is supplied to the top of the IP, 8 by 1 metric fitting that needs hose barbs on the other end, I have a brake bleeder fitting that fits, but is not ideal because there is no t a lot of space for a clamp on the other side of the barb.

Interesting project.  How do the Audi fives compare to the sixes found in '80's era Volvos?  Those don't appear to hold up as well as the VAG fours.  I'd like to stuff a nice five cyl. TD in my Vanagon someday.

[jackbombay]

I don't really know on the first question, and I don't think that the 2.0 will fit in a vanagon, but it might just not fit in a syncro vanagon. Caddywompus tried and it did not work, I think it was a syncro he tried to bolt it up to.

Here is some rpm to mph math that I have worked out from first principles:
All resultsare @3000rpm.
All results are based on effective wheel height of 23" except where stated.(Syncro has 14" wheels?)
 :mrgreen: 5 speed Rabbits are  about 74mph IIRC :mrgreen:


Fd =final drive.        5th is 5th gear

Quantum 1.6TD
'Fd x5th' is 4.11 x 0.73      =68mph

Quantum 5cyl Gasser
................4.9 x 0.53        =79mph

Quantum Syncro
................4.11 x 0.83      =60mph :cry:
 but with 25"   wheels        =65mph

using 5 cyl 5th 4.11 x 0.53 = 93mph
and with 25" wheels:         =102mph :shock: [ or 2060rpm @70mph :lol: ]

Quantum 5cyl Gasser
................4.9 x 0.53        =79mph

Quantum Syncro
................4.11 x 0.83      =60mph :cry:
 

   Does anyone know if the internals can be swapped between the two trannies? Swaping all the gears seems to make the most sense so there would not be a huge canyon between 4th and 5th.

Well, if they're anything like the gas 5-cyl's, they're probably bulletproof.  The 5-cyl NA and turbo engines in the gas cars were WAY overbuilt and took a lot of abuse.  

I took apart an MC turbo engine with more than 150k on it and the bearings / cylinders looked barely used...

Sounds like a great project.  

BTW, I'm not sure if the trans / diff in the QS is the same as the US Audi 4kq / 5kq units, but I do know that people have switched out the 4.11 in the 4kq  for slightly longer gears in the 5kq's while doing turbo (gas) swaps.  I believe those are 3.89.  They seem to like it.

I can find more info if you like...

[therabbittree]

I am collecting parts  for the same swap.... I am interested in finding out more about  this 5th gear swap or fianl drive swap ..or both 389 finals and  .53 5th gear would be nice....a 2.5 tdi would be best but out of my budget..i hope i can get some decent power from th e2.0 5TD..and i hope i can get it to start unpluged when its real cold  with out issues..my old idid aways started suckin g in th ecold unaided..the tdi starts much better in cold even ral cold 10-20below..unplugged.. think i could egt a idi to start in those conditions with out being plaugged in?
... we need more pics and test results..my syncro needs brake work and waspping ..too many projects yet ha

keep ip the good work
later

Maybe this will help for the transmission questions...  It's from an Audi board, but the transmission in the quantum should be the same unit as those from the 5kq / 4kq...

I thought the type 016 box was for the quantum sync But would the gears from the type 093  drop into the type 013 boxes which are the 1.6TD/4 cylinder gasser boxes or is it confined to the type 093 boxes...
Huh? :roll:

[jackbombay]

YESSSSS!!!!!

  Engine in car. Drivers side motor mount was different between the Audi and the quantum, it swapped right over from the old gasser motor to the Diesel though and is looking good now. Nothing unusuall or hard to deal with so far.


   Still need to figure out, fuel filter mounting, battery relocation, removing an air box mount for turbo clearance, fuel pump removall, empty gas tank, etc... Maybe have it running next weekend???
