All depends how much you can do yourself tbh.

Your gonna need to add pick ups for sensors, be it at the flywheel or crank/cam pulleys, inlet manifold will want modding or swapping for a efi inlet, possibly changing the head or using a adapter plate. Then its wiring and mapping unless you can get something pre mapped.

I would deffo go for something more modern, I've had mfi, cossie and now megasquirt.

Have a look at the boostmonkey website.
