I am about to start a transplant of a 110BHP Sharan TDi engine into my Syncro.  If you need more info, shout!

    Subject: TDI redline?
    
    
    Dear List,
    
    What is the "redline" of the VW 1.9L TDI? 5000rpm? 5200rpm?
    
    I need this information in order to estimate whether or not I will need to change the gearing when I install the TDI in my Syncro next year. Note: I'm planning on having the trans rebuilt anyway, might as well optimize it to match the new motor.
    
    Cheers,
