Corsa VXR Engine Build

This low mileage Corsa VXR was booked in with us recently for an engine rebuild. It was a very late car with a B16LER engine.

The whole process starts with removing the engine and gearbox from the car, separating the gearbox from the engine and then stripping the engine down to a bare block and head. The block is then rebored and honed to suit an oversize 79.5mm forged piston and to achieve the correct piston to bore clearance. Once it is fully cleaned the block is then rebuilt with new forged pistons and rings, steel rods, uprated ARP rod bolts, new big end bearings, new gaskets and head bolts. On such a low mileage engine (4k) the main bearings, timing belt, tensioner, pulleys, oil pump and water pump were all as new and could be refitted. On higher mileage engines we recommend that these are replaced as necessary. As necessary the valve stem seals are replaced and the valves reseated. If either of the block or head faces need refacing this is carried out at ther same time as is additional balancing work if required.

Once the engine is built back up with its ancillaries and timed up, it is refitted to the gearbox and then fitted back into the engine bay. Engine oil, suitable for running in and coolant are added and the engine is then run up and road tested. We recommend the addition of Evans PowerCool 180 Waterless Coolant as part of an engine rebuild.

It takes approximately a week for this type of work to be completed.

Here are some pictures of the process:
