hey,if you have a small turbo, T2/k14 or k03-003 keep it. 1.6's desperately need more bottom end power, and putting a larger, slow spooling turbo is going to hurt driveability.
Toss that 3 puck clutch junk too. You'll want to commit suicide within a day of driving that!
zukgod1, I've got a 7A trans in my '91 Jetta TD and the trans program says I should be doing 2693 RPM @ 65 MPH with 195/50R15 tires. Not to hijack this thread but is a 7A transaxle good for our 1.6L TD's? Fuslit, what are the ratios of your current trans?
for best fuel economy per hp/kw produced it is 1800 rpms. The info is floating around the internet some where. I posted it over on the vortex but no one seemed much interested. at 1800 rpms the 1.6 uses 264 grams/kwh (kilowatt hour) of workdiesel weighs between 820-950 grams/liter ~ 885 grams/literso if at 1800 rpms it uses 264 grams/kwh885/264=3.35 kwh/liter of fuel1 horsepower = .75 kwh3.35/.75= 4.46 hp/liter1 liter=3.79 gallons4.46*3.79= 16.92 hph/gal (horse power hours/gallon)
