After 5,000 miles it leaks around where the...

    TDI mated to ZF 4HP22?

    4hp22 to VAG I wonder if Volvo ever put the 4hp22 behind a diesel. They used VAG diesels.. And they used the 4hp22.

    TDI mated to ZF 4HP22?

    4hp22 to WV Most of the 4hp22's have a large nose on the torque converter. 1-1/4" and will not fit into the end of a VW crank. The Volvo has the smallest nose of all the 4hp22's I have seen. But, the converter rebuilders will not swap front half of a torque converter. In your application the...

    DBW nozzles

    Nozzles vs tune Well I went for nozzles first, wanted p 520's, got upgraded to P1019's, way to much smoke. I think, Sale of a set of P 1019"s = additional sale of a tune. Get a tune at the same time as the nozzles. Or just get a tune... Just a newbies thoughts.

(side note: my original intent was to use the P 520’s and an AFN ECU to bring the power up.) Today a Calif. Bosch service center said that they cannot set both pressures and that...

    Biger nozzles and the Catalytic converter

    ALH TDI’s sold in the USA have a catalytic converter. When larger nozzles are installed and no other changes made, will the catalytic converter be overheated as would happen with a gasser running rich. I did an install of larger nozzles (1019’s) and it smoked like a train. I changed the IQ and...
