VW TDi Tech

Dear Editor,

I love this magazine. I don’t have one of the Big Three turbodiesel trucks, but your magazine has a lot of good information on diesels that I can drool over.

I own an ’02 TDi Beetle with bigger injector nozzle tips and a chip by Upsolute. My factory horsepower and torque readings are 90 hp and 150 lb-ft, but with my mods it’s jumped to about 110 hp and 250 lb-ft. For a four-banger that’s pretty damn good for only spending $600 bucks. And when I drive like a granny does, I still get 43mpg on the highway!

There are some companies out there that can do a lot more to a VW TDi than what I’ve got. So I’m asking if you could possibly do an article or two on hot rodding a VW TDi?

P.S. Do you know of anyone that can modify a VW torque converter for high-performance?

Thanks,
Isaac

We’d love to find someone to do an article or two on the VW TDi-know anyone?

Unfortunately, we were able to find out that the standard VW transmission was never designed to survive the kind of torque you are now generating. However, John at IPT Performance Transmission (1105 Rt. 23 South, Wayne, NJ, 07470; 806-828-7267) advises that they can beef a torque converter to live behind your torque output quite readily. They do it by putting in a better clutch pack, among other things. The valve bodies are another weak point so they re-bore them and install oversize pieces. The end result is an automatic with more definite shift points and much improved reliability.

Perhaps our readers know of other sources to address transmission reliability issues-ed.
