The turbo used on a Glanza is a CT9 by KKK i believe you should be able to pick a half decent one up for around £100-£200 and it would be ample for the endura engine, they are good for around 1.3 bar but 1 bar is a good reliable area to run them at even better if its been ported.

I sold the car over a year ago now so dont have any pics unfortunately but it was running an RX7 Top mount which to be honest is no bigger than a standard S2 RST item, run a double capacity S2 and you should be fine i never had any problems with charge temps.

The car ran electronic fuel injection and the ignition was taken care of by a rotor arm and coil like most japanese cars. You should be able to sort the injection and ignition out for fairly cheap but you will need aftermarket management for it which you can pick up 2nd hand if you shop hard enough.
