Hi to all,

I bought these original cooper engine 997 to my car, i read some comments on the web that these engine is not a very good engine.

 

 

so the best is to keep it original and look for a new engine for tune it or can i make some tuning to put it more "fun"?

 

Thanks to all

Jorge

best to leave it complete. they are very rare these days. if you dont want to use the engine then buy another to use. this engine is the sort of thing you can lock away and let it grow in value.

like what he said but it would be a good side project if you wanted to rebuild and engine for experience even if you just rebuild it stock. you could then just sell it on after

a blueprint rebuild only though.

In all honesty there is far too much to go into here, but there are a few basic steps to ensure reliability first.

 

The engines main downfall apart from the bore/stroke combination were the clutch and the pinch bolts in the gudgeon pins.

 

These engines can however be made to go quite well.  If you intend using it, the first thing to find out is which clutch and primary gear is fitted.  If it has the wet primary gear with the oil seal in the flywheel then it is best to change the primary gear to a later one and plug up the oil hole in the crank tail.  From there you can start to make the engine reliable without changing how it looks when reassembled. 

 

More details can be found on the MK1 Performance home page about how to do this.  Then you will need to do some research before rebuilding the engine.  They are mainly the same as any other A series with just a few quirks.  I have a 997 and have used the original engine before retiring it for a similar replacement.
