Dear List,

If I install a 1.9L TDI in my Syncro it seems as if I will have to reduce the final drive somehow by approximately 88% to keep the effective speed per rpm ratio.

Current wasserboxer redline = 5200rpm

Current wasserboxer @70mph = 4000rpm w/ 27"x8.5 tires

Future TDI redline = 4600rpm

Future TDI @70mph = 3550 w/ 27"x8.5 tires

So to the question: if I change the final drive from 4.83 to approx 4.25 it seems as if I must also change the FRONT differential drive too -- correct? or am I mistaken?

Is there anyway else to do this (other than adding "monster" tires)?

How about changing all the gear ratios? (I'm gonna rebuild it anyway)

Cheers,
