I have an Rb25det head and complete bottom end. The head is in very good condition and ready to bolt straight on. the bottom end is fully dissembled, the crank would need a re grind and the bores would need a hone at the least. Bore is still in standard form so will take a 1st oversize bore no problem. There are various other engine, suspension and intake parts available, pm me for prices and parts you require.
