a club mechanic has done it..
he frankensteined the gearbox with an rx7 front and mx5 rear housings.
welded a new cross member extension to the original cross memeber to hold the front of the rotary block.
massaged the trans tunnel to clear the bell housing as the rotary sits the crank height higher than a 4 cyl.
thats the main bits. other things like low pressure fuel regulator for the ida carb etc etc.

It's been covered a million times, and what you want specifically relates to your definition of 'performance'.
Have a search and a general look around the forum and you'll find the answers you need.
Help yourself first

Step 1: Name a car, that goes as fast in a straight line as is satisfying to you.
Step 2: Calculate its power to weight ratio.
Step 3: Calculate the power needed to make your mx5 have the same ratio (mx5s weight and power available on wikipedia) "X".
Step 4: Search
Step 5: If you STILL need help, open an intelligently worded thread asking how to achieve X rwhp.

David,
Go chat to the guys at MX5 Plus, they'll be able to show you different options and explain the costs involved.
