Need to install a 105mm rear main seal into a 991 Porsche 911? Make sure you set the seal to the proper 7mm depth from the surface of the crank flange! If you install the seal without a tool that controls the depth, you'll likely install it too deep, and you'll have a high risk of a leaking seal. It's simply too time consuming to do the job twice, so do it right the first time!
This is an affordable alternative to the costly (~$400) factory tool from Porsche. Simply bolt this tool to the crank using the flywheel bolts until the tool bottoms out on the crank. Remove the bolts, verify that your depth is even, and you're done!
This CAD designed tool is 3D printed plastic, and is safe to use on your seal without risk of damaging it or the bore that the seal sits in.
The APR GTS K04.3 Turbocharger System converts your 991.2 911 3.0T to the larger factory GTS turbochargers and includes our Stage 3 ECU Upgrade making the conversion plug-and-play! Up-to 615 HP and 549 FT-LBS of torque is available with no other modifications. Adding upgraded intercoolers bumps power up to 648 HP. This is a substantial increase in power and torque. Expect up to an additional +263 HP and +266 FT-LBS over stock on the base engine, and +244 HP and +223 FT-LBS on the S engine! This conversion system, sometimes dubbed an x51 package by Porsche, includes all genuine parts. It includes two new and genuine Borg Warner K04.3 Turbochargers, new gaskets, and o-rings. Simply remove and replace the factory components with our new components. No other hardware upgrades are required as the 3.0T mostly shares the same components, except for the turbochargers, from the base model to the GTS model. This system works with your factory engine hardware, factory fueling, and factory emissions components. It even works with upgraded engine and exhaust components and picks up even more power with upgraded intercoolers! This is all made possible by the included world-class APR Stage 3 ECU Upgrade which is programmed to your factory ECU at no additional charge!
