It could pay to read the rules before cutting the metal.

Don't believe what you get told on forums, do your own research and get the facts.
The authorities have set rules as to what is allowed and why. Just because a Corolla can fit a particular motor does not mean a Mini can do the same thing. In case you have not noticed a Corolla is a slightly different car to a Mini.
Probably because a Corolla weighs more than 800kg so the engine capacity multiplier changes to a higher number
I.e: The max capacity in cc's for all cars weighing...
...under 800kgs
Nat Asp - original weight of car x 3.0
Turbo/Super - original weight of car x 2.5
...800-1100kgs
Nat Asp - original weight of car x 4.0
Turbo/Super - original weight of car x 2.75
...1100+
Nat Asp - original weight of car x 5.0
Turbo/Super - original weight of car x 3.0
