I've been reading about wastegate springs. One poster has said that installing the stiffer springs in a K16 is not a prudent thing to do. The spring is keeping the door shut too long and making the K16 turbo work too hard. In the end you have a ruined turbo.

And now I was poking around inter web and found a vendor selling upgraded K16's with wastegates with the stiffer spring. I'm trying to understand all this as I want to possibly do a tune when I get my turbo.

Here's the web page from the modded K16 vendor.

The AMS Porsche 996 K16 Billet Turbo Upgrade are the most advanced improvement you can make to your K16 based turbos. Using new aero design with extended tip technology, we replace the OEM compressor wheel with a larger CNC billet unit for higher flow and increased efficiency. The result is an incredibly quick spooling turbo that pulls hard all the way to redline. The AMS upgrade is completely bolt-on and fully compatible with all stock components and comes complete with upgraded 1 bar wastegate actuators to maintain optimum boost throughout the rev range.

What does this all mean? By integrating this unique billet design we are able to keep the quick spool characteristics of the factory K16 turbo and vastly improve on power output. At comparable boost levels the AMS Billet K16 produces power on par or exceeding larger, later spooling turbochargers like the popular K24/18G.

Estimated horsepower output
550-580 hp / 570-600 lb/ft of torque on pump gas
600-630 hp / 660-690 lb/ft of torque with optional AMS Fuel Upgrade Kit

Do you have the car yet?

You will have to put monies into the newly acquired car, tires, clutch, oil change, detail or XYZ..

To answer your question, I do NOT recommend installing a actuator kit or different actuators on STOCK K16 turbochargers. The cut and paste info that you posted, is for K16 hybrid turbochargers. Anytime you upgrade the compressor stage to a larger compressor wheel, one can then upgrade the actuators.

The ECU tune and exhaust is usually the first upgrade, if you buy a X50 car, you can add the actuator kit on the STOCK K24's..

So the turbos they are selling are not the stock K16s. They are modified and they include modified waste gates to go with it. Just what I am reading, I know nothing about the product.
