While many are scrambling to find an RS 4.0 allocation, we are taking a different approach. Allow me to introduce the IPB-Autosport 4 liter project.

First things first, the engine has to come out. After removing the airbox, draining and disconnecting the coolant system, evacuating the A/C, disconnecting power steering lines, fuel lines, engine harness, misc vacuum lines, etc, the car goes up in the air.

Once the plastic underbody panels are removed, we gain access to everything else that has to be disconnected: axles, cross members, sway bar, starter, ground, transmission cables, clutch slave, additional coolant lines including the tranny cooler, and of course engine/transmission mounts. The whole unit drops out.

All the parts are stashed on a cart, and the transmission sits nearby. Once the case is split and sent off to machining, the differential will be pulled and rebuilt with Guard internals.

In the engine room is a freshly rebuild air cooled engine waiting to go into a genuine 914-6. Numerous flat-6 engine parts everywhere – accumulated through years of engine building experience.
