The price will entirely depend on how much of your existing set up is salvagable.
If the cylinder heads are good and can simply be faced and reused, if the clutch is worth re-installing, the timing belt idlers etc are all good to re-use the price will be lower. If you start with new everything and upgrade some parts you could easily add up to lots more. Obviously your radiator is new so that's one less cost in the whole scheme.


There are lots of ways to cut the budget, but be carefull of a low 'quote' that does not include averything it should have, or one that blows out to double once you commit.
