Days 20 and 21

The final preparations were made to the engine bay before the engine arrived, which included thoroughly connecting all the hoses together with zip ties and cable clips where required, and double checking that all the joints had been torqued up correctly. The wiring was moved out of the way as much as possible to ensure that the engine hoist would not run over and damage any wires, and equally to ensure that the engine would not damage any should it come into contact or trap them against the chassis rails.

The engine arrived, complete with ECU (and minus loom due to a shipping incident) on a pallet, which was offloaded to the MacG Racing workshop. The engine was man handled off the pallet, then the engine hoist was used to pick up the engine, using some spare bolts that were attached to the heads. Lifting straps were located on these bolts and were used to distribute the load evenly and ensure that the engine remained straight and level. The engine was manoeuvred into place using the engine hoist, and it slid into place pretty easily.

An engine pre-fit was conducted so that the Team could asses how much alteration was required to the components on the bulkhead to accommodate the different frontend on the engine. Fortunately only a couple of items needed slight adjustment, so the engine was lifted back out of the way whilst the parts were moved to their new locations. Whilst this was being carried out, another member of the team fitted the standard Ultima engine mounts to the engine.

The engine was then lowered into place, and a prybar was used between the engine mounts and chassis to ensure that the mounting holes were lined up correctly and that the bolts were able to slide in without and problems. These were then slid into place and left loose; these will be done up after the gearbox has been fitted to the engine. The hoists were removed, and the few components that were removed from the engine to avoid being damaged whilst the lifting straps were being used were refitted. Oil lines for the dry sump system were built up to the correct length and loosely fed into the correct position. The dry sump tank would be fitted post engine fit to avoid it being damaged should the engine come into contact with it whilst suspended from the hoist.

To get an idea of what the engine would look like when installed, the clam was temporarily put back onto the car. Now the difficult job of identifying a suitable gearbox and exhaust system was about to start…..
