2512cc Opel 8V CIH Competition Engine

Check out the latest news on the Engine Building Page.

Introduction

Changes from my previous engine will be limited to the block and head.  Things that won't change are the cooling system, engine management and fuel system, and the flywheel and clutch.  Those parts which have not changed have simply been copied from the page about the previous engine.

For some time I have been toying with the idea of installing a more powerful engine.  The obvious, is to install one of the newer Vauxhall 16V engines, or a little less obviously the Rover V8 unit.  Each has it's good and bad points, but I think that I would have gone for the Rover V8 unit, simply because big cc's means big torque, which is very important in Hill climb events.  However, in the Motorsport Association (MSA) Hill climb events that I compete in, a modified production car must use an engine block as supplied in the original vehicle.  So, if I fit one of these engines, then I will be transferred into the 'Sports Libre' class which is usually home to the Class B Rally Cars, like the Metro 6R4s, Audi Quattro S1/S2s, etc.  I don't think so!!!!

The new 2.5L engine is to be installed in a modified 1979 Opel Manta B, and used for Hill Climb and Sprint events, as well as being driven on the road.  The UK Motor Sports Association class rules, for Modified Production Saloon Cars, require that the car must use an engine block as originally specified by the manufacturer.  In the case of this car, this is the Opel 2.0l CIH block.
