Thanks
Right now the hope is for a TDI. Price of the labor for conversion is the
same, about, for either a TD or a TDI and I've had a TDI and liked it.
I guess the Tire Rack would know this, and then I can calculate the percent
change in rpm. The gearing change is 25% and I kind of doubt tires can make
that much difference but maybe?
