Only info I've seen is to go a couple heat ranges colder to keep them from pre-igniting (from the electrodes getting too hot iirc). They can give you the part number at whatever parts store you go to. I prefer NGK.
My experience has been heavy with the 2.2 and 2.5 engines leans towards not far from the factory plugs.
The 2.2 engines used the same plug as a 318, RN12YC. With the fuel injection you could get away with a 340 plug an RN9YC with no ill effects but I never saw any benefit even at 30 psi of boost.
Here is some NGK Tech Data for reading/understanding their part # designation....

I recommended you a B R 8 E S......as a general recommendation for turning up a SBM with some boost....
Its a Very Conservative Recommmendation, as well.
You may find a NGK B P R 7 E S to be the best.....but heed my advice to stay with a Standard - Copper type spark plug....and dont go any hotter in your experiments than a 6.

Use a 'non projected tip' plug with boost or Nitrous.
