It takes a good bit longer to install a turbocharger than you’d at first think.

I set up to check out the preload on the wasetgate actuators to ensure they are balanced and set to an appropriate level for the K04’s.

I use the air compressor in conjunction with the regulator for a leak down tester to gradually apply air pressure to the wastegate canisters.  It also allows me to get a fairly accurate reading of the air pressure necessary to start opening the wastegates.  The BorgWarner K04 canisters are loaded to open at approximately 7 psi.

Here they are in motion:

Completed the removal of the motor, 7 hours total doing it solo, and took the driver side turbocharger off.  The K04 is just about ready to be installed.

While the motor is out I’m also swapping exhaust manifolds, going to a set of Swaintech white lightning ceramic coated stock manifolds.

After wrapping up the K03 dyno session yesterday I’ve got all the data I care to collect for now on those turbochargers.

Today I began the process of moving up to a pair of BorgWarner K04’s.  One addition to the toolbox this time around is a Milwaukee 3/8″ drive electric ratchet.

I’m hoping that the electric ratchet will help to speed up the engine removal process.

I put in three and a half hours today and made some good progress.  I’m hoping with about two more hours time I’ll be ready to remove the motor and start to swap over to the K04’s
