Megasquirt or similar.
Getting oil in 'n out of the turbo would need a custom solution too. Might be better to start with an older block and avoid emissions issues as well.

I was thinking about that but wouldn't the emisions be due to the 98 not the engine? i would need a cat wouldn't i? is there a way i could drop the ecu and injection system and add carbs go down that route and turbo it?

Yes, if you swapped to an older engine: emissions are tested by the lower standard, provided you can prove the age of engine or car. Lots of keen turboists are moving to injection and the costs may not be so bad if the alternative is to splash out on a Carb and related bits. The other issue would be packaging it all under the MPI's already chocka bonnet space.

It would probably be easier to start with an older block as the turbo oil return feeds back in where the mechanical fuel pump goes. MPI blocks dont have this. And the turbo blocks had a little bit more meat on them. You could still use your orignal transfer casing, flywheel and TDC sensor. So theres no need for a trigger wheel set up on the bottom pulley
As far as the fuel and spark goes it depends on the type of inlet you intend to use. If you intend to use the standard inlet manifold and throttle body. Then you will need an ECU that can deal with the inlet phasing of the mini. Camems can do this not sure how it will deal with the turbo. By using the standard inlet you can still use the injector positioning aiming at the back of the valve. But the injectors would have to be large to cope with the fuel that will be needed. Which will makle it hard to control correct fueling at idle and crusing throttle positions.
The other option is using an old MG 1" 3/4 carb manifold and replacing the carb with a Jenvey throttle body that will take 2 injectors in the body itself. This means accurate injector phasing wont be needed because the mixture will be pre mixed before it gets to the back of the valve. As it would be on a carb'd car. For this set up i would use an Omex 600 ECU. Little bit more expensive but well worth it. This option would probably create more space as well.
