short answer..... it would be rude not to! :D

you will need a bulk head box if you are going to run the turbo

You can but its not as easy as most will tell you:)

First if you want to fit a MG Metro Turbo engine in a Mini, You have to make a gap in the bulkhead because you need some space for the Turbo that is fitted at the back of the engine. To fill the gap you need a bulkhead box, there is one fabricated bulkhead available at Avonbar Racing (ABR 028) or you make one by yourself. When the box is fitted there is some stiffening of the bulkhead recommended. If the engine is fitted, the top engine stabilizer is to short, make it longer or fit an adjustable engine stabilizer from KAD, there is some more engine noise with it but with the left and right threaded ends it is easy to adjust and it looks very nice too! On the under side of the engine to subframe, fit two engine stabilizers with polyurethane engine steady bushes.
If you plan to fit a new exhaust take the Maniflow LMD680 Mini Turbo Down pipe and the ABRLS023 Mini Turbo system (only available at Avonbar) this is a single box side exit, with 2" dia. I fitted this one and it fits very well and the sound is nice, because of the Turbo that works as a muffler a single box system gives the same noise level like a non turbo engine with a twin box system.

The Engine

If you want to improve the standard Turbo Engine, I recommend fitting a dump-valve. There is a lag e.g. when You shift to the next gear, without dump valve the Turbo is building up pressure, but the throttle valve is closed so the Turbo stops itself because the pressure gives it some resistance. Now, if there is a dump valve in the system, the excess air pressure can go out when the dump valve opens. It is a great improvement!
The membrane from the dump valve needs vacuum; take it from the intake manifold.
Remove the standard Metro Turbo ECU if you want to give it more boost. The bleed setup as used normally to get more boost will not work good with the SU carburettor. You need a modified actuator to run on higher boost levels.
With these higher boost levels your minimal need is to have a cross pin diff!!!
Typical engine setup, is rated at 158 bhp at the flywheel and 137 bhp at the wheels.
