What a Stage 2 usually needs
It depends on the engine, which is why the workshop part is quoted: the centre looks at your car before writing down a figure. Typically:
- turbo petrol: almost always a sports downpipe, often a larger intercooler;
- diesel: usually a more efficient intercooler and, where needed, a downpipe;
- clutch: assessed when torque rises a lot or it is already worn;
- if the car already has some of these parts, the quote is lower.
