From what i have seen tuners say that anything over 600hp you should have liners

for somthing like rods 700+ engine it must have custom liners
to have a Block long studded, with custom liners would be about £2000 and to Quote mark
all the best bits ie Pistons/Rods/Crank allow nearly £3300+vat
so for all the bits mentioned is about £3900
Doesnt sound a lot when you look at it like that
