Thread: Spreadbore Performance Improvements

In the future I am going to have to rebuild a 2 litre Spreadbore engine to go into my Station Wagon which will be restored.

As such when the engine goes in it is to look standard - so standard carby, standard dissy and exhaust.

However if possible I would be like to be able to incorporate safe performance improvements to the internals of the engine.

Now I am generally familiar how to improve performance in general terms eg, increase capacity, increase compression, bigger valves, headwork and rejet the carby to match changes but what I am after is information specific to the 2 litre engine.

So if you have improved the performance of a 2 litre what works and what does not - things to be wary off.

Thanks

While we are here, have been advised that 2.0 ltr Rover engines valve bounce in a S1 at around 50mph. (Self limiting Is this correct, and if so can one use double valve springs, and will this improve the rev range?

As for doing the other stuff, given the 3 bearing c/s, how robust is the engine, and how much extra torque or power can it handle and maintain at least LR reliabilty.

Cheers
