Well I suppose I'm all out into simplicity. I like the crude design of the Astra GTE 8v - there's nothing to it really. It's simple cheap speed and that's what I want.
However, I'm not in a position to say much about turbos really. I'm sure that they provide more kicks (I saw Phil Ds Astra GTE turbo move ) and are probably fine if looked after. They are a more highly stressed engine, so more care needed.
