Spreadbore Performance Improvements

[101RRS]

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

Hi Garry

All those things on your list and along with changing the innards of the distributor to electronics.

Or wait for a frosty night. :angel:

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.
