Please can you tell me a good coil for
1380 with a59d distributor?
Thanks

Nothing?
I have a 1380,the old coil was the standard rover spi coil.
Is this ok for a 1380 with 59d distributor?
Thanks

Any good 12 V coil will be fine. There was some unreliability with the Lucas Sports coil a while back. The standard delco 12 V is excellent and I have that on my 1310 'S' with c.115 bhp.

Is the car ballasted or not? The engine being larger makes no difference to the coil, it still has to provde the same number of sparks in the same time (same number of cylinders) and that's the only thing that might really change the performance expected from the coil. You can largely ignore anyone who tells you that you need an amazing coil that produces incredible sparks, sparks just need to be hot and happen at the right time. If you're using electronic ignition there is nothing you can really do to make the sparks any hotter, or need to do. If you are using points ignition you could make them a bit hotter but it's not that necessary.

It's been pointed out to me by DK that I've made quite an assumption here. When I say you can't make the spark hotter in a car with electronic ignition, I am assuming that the system has already been fully optimised by opening the plug gaps up as far as the system will allow. This is how higher voltages and so hotter sparks are generated, and with electronic ignition the system can support a wider plug gap than with points.

With a standard 12v coil like this

After some good rpm the coil became really hot.

What can i do?

Do about what? Coils are meant to get hot in use, that's why they are full of cooling oil. The coil is a 12v to several thousand volt electrical transformer, and at high RPM it's running at 70 - 100 Hz or so. Do the electrical transformers in your home get hot? Does that worry you so much? Because they are working a lot less hard than the coil does. If nothing has actually gone wrong or stopped working or become faulty and the only thing you have noticed is a hot coil, then there's probably nothing wrong.
