It wouldn't be possible to do on the Corsa E unless you had silly money to play with because it's not a case of just bolting the turbo on your engine architecture is completely different, you would need an entirely difference ECU, all the sensors would be missing also such as MAP sensors, the manifold would be different and generally speaking would be an electrical nightmare to fit, a new ECU alone is around 1.5k to buy that's without having Vauxhall program it to your car then you'll need the new engine wiring loom and that'll be around another 1k then you'll need the sensors the lot
