The turbochargers that I intend to try out with the Mamba wastegate actuators are the Frankenturbo F21 retrofits. This evening I installed the Mamba wastegates to see how well they would fit on the turbochargers.

The new wastegate actuators fit onto the turbochargers without any problems.

So far I am impressed with the Mamba product, it looks well constructed and the initial fitting went well.

Next up I am going to play around with the preload spring options.
