End of the day whenever you decide to mod the car and start pushing high 200,s plus on stock engine we all do it knowing all well that theres a chance that the engine might die sooner than expected but theres to many variables how you drive , how much you drive it, and of course the tune.
Of course a car tuned at 350kw which is a daily and never sees all that power being put down will last longer then someone at 280kw thats smashing track work constantly. But atm it seems like the median of what people go on stock is 300kw and also consider running on e85 for abit more security.
