Sometimes Ali Burrows has 2nd hand engines for sale aswell, and Ali wouldnt sell you a crap one, i presume that 1500 is only a hand in your block andthey hand it back rebuild price and doesnt include taking out engine, stripping, putting everything back onto block like heads, gaskets, timing belts, oil pump, oil modene etc etc.. finally fitiing the engine back in, fluids and getting her running. for rough idea, as far as i camn remember. it worksout around 3 to 400 euro for new oil pump and modene alone, head gaskets around 100 euro, timing belt around 100, oil and coolant around 100 euro etc etc these just ropugh prices and will probably cost more. i dont want to be frightening you but there is only one cheap way, and thats 2nd hand engine.. and thats at best a 50/50 chance..
i am facing the same delema, mine is a higher tuned one but now i am faced with being able to buy a real nice car for the price or less of an engine... see a 99 v5/v6 white sti for sale in Kilkenny on Donedeal.. under 4k!!!!!!!!! no nct and needs tyres
If you not able to work on it yorself ask the likes of Ali or Dave the price of a trailor in drive out rebuild and compare to trailor in drive out 2nd hand engine fit.. weigh up what year your car is and what its worth mate
