Is there any reason not to supercharge a 2.1 conversion, or is it even possible? Discuss
Am considering having that done tbh. After I refresh every last bit if suspension

It depends on how high your compression ratio is.

no reason why it can't be done, though with the power gains you get from just the standard 2.0 there's no point really.

Surely you would have epic torque though? Any educated guesses as to what you would end up power wise

5% more than a 2.0?

Not a lot...

So its a no then? Would it be more reliable? I.e under less stress when making the same power?

No, re-boring that far will increase the risk of engine failure.

You'll gain a little power and torque yes, but assuming you're taking about low boost it'll add about £1k to the cost (machining, pistons, mapping, etc.)

If you were going to go to the extent of changing the crank then for supercharging purposes you would be better off going for the 2.1 td crank and getting almost 2.2 with 87mm pistons?
