Twin Su 1.5" Type Hif

I have a 998cc rover mini mayfair and just wondered if it was worth putting on these twin carbs or ifits just over kill. they are off a mg bgt and just lying around. Or if anyone has any tips on the best twin carbs to get.

Thanks chris

The twin 1.5" carbs are a little too big for the 998. Twin 1 1/4" would be better

Would it cause more problems than good like overfueling
