Turbocharger OEM Volkswagen or BorgWarner

I have 155K+ (chipped at 100k) on the original ko3, It has outlasted the clutch (100k) and exhaust (135k) full synthetic every 5k, always cool down after a hard drive. Still solid.

Well if it matters I just hit 108k miles on my k03s. Been chipped since around 60k. Added a tbe at around 80k. I used whatever the dealer told me to use for my warranty period (50k) changed every 5k miles. I switched to full synthetic since then and still change every 5k. Change the plugs every 40k until I switched to the NGK 7Es which I change every 10k. Timing belt every 60k, fuel filter every 50 along with tranny fluid. I just hit 108k yesterday and I still have the original clutch and dv.

In my '00 Golf it lasted 189,000 miles. 174,000 miles chipped.

You guys should really check out that R2S, it's is MONEY.

Having driven my 2001 in both modes as well, I would say the top-end gains are where I felt a change, but even then, we're not talking 5-car-lengths in races here, folks. That being said, my K04 works nicely and the torque feels a bit more broad and I am enjoying it.

Mine just let go at 161400
