[Vwdiesel] 1.6TDI

[Shawn Wright]

It seems we share similar feelings about power requirements... but I think we are a 
very small minority! (my NA Jetta feels positively snappy most of the time :-)

I think the biggest problem would be pistons - you may need to source Euro 1.6 
pistons, and possible rods and crank. The TDI pistons have the combustion chamber 
built in. I think the main reason for the 1.9TDIs (aside from the general desire for 
more power in the US/Canada) is the added weight of the newer cars. A new G/J is 
about 600 lbs heavier than an A2. That said, the current TDIs still have way more 
power than they need. My Dad says their '03 Automatic TDI Jetta can storm up the 
grapevine passing just about anything, even loaded to the gills. And it still gets 
45mpg with the cruise set at 140km/h.

A 1.6TDI with mechanical injection would be a great solution for sure - the TDIs are 
nice, but I don't like the drive by wire, or all the things that can go wrong in the 
electronics.
