Ok
I was thinking Honda swap but due to cost ... Vtec doesn't work
So how about super charged ?

What parts will I need to make my 1.3i mpi motor ready for super charge ?
Where can I get these parts ?
Also how much power will I get with super charge and stock motor ?
Any info can help !

You will need to take your standard injection off the car and use a carb for example.

It wont work with the mpi fuel injection part

Not true on the carb. You will need to change your ECU and lose the manifold, however. MPI system still used, throttle body up front.

See Palmer Bro's Pickup for example:

you cannot reliably just bolt on a supercharger, the compression ratio of the engine needs to be calculated and then adjusted to suit the forced induction, (it will need lowering with either pistons with a dish or the head modifying to lower the compression, you can use a decompression plate which is like a thick head gasket, it does lower the compression however to many it is seen as a bodge.

Then you need a supercharger kit or all the components, you need to decide if you want a suck through or blow through system, both have their own positives and negatives, the picture above is a suck through system which runs the carb before the charger and sends atomised fuel and air through the charger compressing the mixture and into the engine, this limits overall power because of the extra heat created from the supercharger, and its very difficult to cool the air before entering the engine. This system is easier to install in a mini.

 

blow through just has air running through the charger which then enters a carb or throttle body which mixes with the fuel and into the engine, this system allows the use of an intercooler which cools the air which was heated from the compression of the charger, cooler air is more dense and thus gives more power, however it is much harder to install a blow through system on a mini due to the space requirements.

this isnt a quick bolt on mod and research is vital unless you want an expensive repair bill if it all goes wrong, turbo minis is a good website for forced induction on the mini also David Vizards tuning the a-series has a vast amount of information  about tuning the mini engine including a chapter on forced induction.
