six cylinder rover.

The 3 litre straight six as fitted to the P5 (I had a 1963 coupe) was a great engine. Westlake head (top inlet/side exhaust) was so smooth that people used to ask me to start it up when they were standing next to it, even though she was running :) I thought this engine was derived from the landrover engine.

Rover had variety of IOE engines, the 2.0 four went into the original Series 1, to be replaced by the 2.0/2.25 OHV four at a later date. The

The IOE engine is an old design, Landrover must have been the only manufacturer still fitting IOE engines into cars in 1980. It was only with the advent of the Stage1 V8 that they finally dropped the 2.6 IOE in the Series range. The V8 came earlier in the Rangerover and the

No, the P5 engine is a close relative of the Series 1 Landrover engine - although to say it is derived from it is hardly accurate. Both are overhead inlet/side exhaust and are excellent engines. The Series 1 engine was not designed as a four wheel drive engine but worked well. The P5 engine, when put into the Landrover, was less successful, although my view is that it is somewhat unfairly maligned. As fitted it was derated to use lower grade fuel, and had high fuel consumption. It proved less robust than the earlier engine and especially than the contemporary four, partly because the alloy head made it less tolerant of overheating, and it did not like lugging, but would do it! The 2.25 is a completely different engine, designed from the ground up with straight overhead valves. It is derived from the diesel (or more accurately both were designed in tandem) and as such is overdesigned - a very valuable property in a four wheel drive engine! As to why Rover did not adopt the Santana six cylinder version, I suspect it was because it would have been a direct competitor to the V8 that was already available in the Landrover, and was already in production, and used in other products.

Hi! - Off on a slight tangent here: -

Land Rover experimented with the 2000 cc overhead cam 4-cyl from the P6 Rover 2000 (in the Series 2A I imagine). They also experimented with a

After British Leyland was formed one wonders whether fitting the 6-cylinder Triumph 2000 or 2500 engines was ever considered. I bet some owners have fitted these engines to their Land Rovers over the years.

Maybe this can be done... we used to have (and adore) an unusually well put together SD1 with the 2300 6-cyl. I always believed that, like the bigger

So, since it's been installed in a car designed with the ubiquitous V8 in mind, the same mounting adaptations employed in the SD1 would presumably make it at least remotely possible to fit it to a Landie.

Anybody tried it?

Have a look at

British Leyland was a total nightmare in terms of management and intra company rivalry (e.g. why did Triumph continue to develop their own V8 for the Stag when Rover already were producing the V8??) and, AFAIK, the 6 cylinder engines died a death around the same time as Leyland (The SD1 went off to India where it was produced in a 2 litre format - it was already exported as a CKD but all the tooling was sold out there too) I think the Vanden Plas Princess 2.2 used a transverse version of the 6 cylinder but, otherwise, that was it.

Fitting this engine to a current LR would be OK in engineering terms as the power, fittings and torque output is close to the V8 but where can you locate spares? Indeed can you locate an original engine?? I'd reckon that (within the UK) a Ford V6 at 3.0l or 2.8l would be a much more likely refit rather than the Rover one - hell, fit a V8!

thought about it once, but the car I was looking at as a donor turned out to be a 2.3, and I didn't reckon it would be powerful enough.
