Hey guys, going to replace the turbo on my 04 Jetta bew. Looking for recommendations on best online shop to order a stock turbo from. Who's got the best price?

The turbo in your car should be a Borg Warner KP-39.

If you are at all interested in allowing for future power upgrades, you could install this, which is cheaper: https://www.idparts.com/garrett-vnt-17-turbocharger-a4-bew-p-761.html

If you want to keep your EGR system functional, make sure to select the check-box to add the EGR cooler pipe for $60. It's a bit longer than the stock one and is required when switching to the VNT-17 turbo.

So combined, those cost $859.

To get the original stock turbo is $929

The VNT-17 is a "stock" turbo for the 150HP European version of your car, so it just bolts right in, other than the need for switching that EGR pipe.

Once you have the VNT-17, you can run it with a stock car, or, you can add a 3 Bar MAP sensor for about $40 or so, and then get a performance tune to increase your power to about 170 HP. You'd need a new clutch to support that though...so that gets expensive.

If you just want to use it in the stock configuration, the VNT-17 will probably outlast the original KP-39 because it's a lot bigger and won't be working as hard.

There would be a small amount of extra lag with the VNT-17, unless you get the car tuned, but it's not too bad. I do have a tune, but I've also driven with that turbo on the stock programming and it's fine.

OK, I bit the bullet and bought the vnt17 from idparts. Now what tools do I need? I'm a Cummins tech so I probably have what I need but I'm in Wisconsin and the car is in Arkansas. So, I want to pack what's necessary not the whole tool box.
