Your only claiming around 150bhp though, I wouldn't be far off this with my revo, then with the k&n panel filter and tb powerflow system on top, I wouldn't be surprised if I was in the if not close to mid 150s. On top of the the weight loss I've gained from removing the AC and standard battery, would contribute as well. We're both restricted by the gearing power wise anway, so even with your hybrid turbo(but standard injectors etc.) We wouldn't be far off each other. It's my kw v2s, kw front and rear arbs and complete powerflex bushings kit that will make the difference whenever any kind of corner appears.
Not that any of this matters, I'm not afraid to admit that most of the Leons of the guys and girls posting on this could still beat either of us in standard form. Anyway you buy a 1.9 for looks mainly, and I know its all personal preference but imo a full btcc kit, lowered on 19" S5 alloys and awaiting an fr interior, looks better than a standard stylance with an aero bumper.
I'm not being mean either, I wouldn't risk getting crushed, I'm just showing you how unrealistic your being
