Not sure. The system I am designing will be similar to this:
Major differences:
My version will be built around a cheap, commonly available Eaton M62. The packaging of this charger is not as neat as the one above, so the manifold will be a very different design
The above system uses an Eaton M45 charger. It's under-sized for a 1.6L engine. The M62 is a better match
The kit is designed for throttle response, and to make good power. It is not designed for extreme power. It should be able to make similar power to a mildly to moderately modded XR2. (130-180whp)
Due to the packaging, there is no intercooler. Should be fine for very low boost, but water or water/meth injection just behind the throttlebody will be recommended.
The charger
should be able to run on stock XR2 electronics & tune. So no super expensive or custom engine management. But I'm not positive on this yet. So if you have an N/A you will need to grab some XR2 engine management.
