Audi 1.6 TD B3 snapped cambelt

[JMLAudi]

Hi all

I got a request for your experance,and opinions..............

One of our B3 Audi 80 1.6 TD has snapped cambelt ,totalling the engine.
My question is .i have a spare 1,9 TDI ,1Z engine,..................if i fit the 1.6 td injector pump,to the 1.9 engine, would the pump handle the bigger engine?

Would there be any serious problems for the engine?


Your thoughts,please

cheers

The TDI is direct injection....nozle opening pressure is diferent.
Teoretical.....iff you increase a little the 1.6 injection pump fuel debit...then will work.
Not as good as the ecu controled TDI...but will work.
Wy you dont fit the ecu and loom from 1.9 ?
Is not soo complicated.

Hi
thanxs 4 quick reply

i dont have the loom/ecu or pedal assembly from donor car

The seller had scrapped the car,before i got there,he just removed the engine ,he had removed the dash already to sell ,it wouldve been so easy,for me to hve taken everything..................( this engine was going to be a spare for my TDI Avant )

Was hooping to have saved some money

Hi
any question


IF i swop over the injectors too from a 1.6 TD engine,as well as the pump...would that be a better answer?

They dont fit!
Direct injection on TDI versus Indirect at 1.6.
The injectors are diferent.
The 1.6 pump can open the nozzles from 1.9....just give some extra advance at the pump and more fuel to compensate the 300cc and opening pressure.

At 1.6 td the nozzle opens at 155bar versus 190-200 at 1.9 tdi 1z engine.
Fit the pump with 1mm advance and turn the power screw behind the pump 15 minutes clockwise and see what hapends! probably you will need to reduce the idle speed also a little.
All the best!
