Daz xr6t

Hi sorry Ive driven Expensive Daewoo V8s since I got my licance years ago but decided to buy a ba XR6 turbo a few months ago I got the car of some bloke who told me he had done forged internals and I only had to worry about bolt on mods the car was running over 15 pounds and within 2 months of driving it I was hooked most intence thing I've ever driven untill I Hird a loud bang with bent the rods smashed the head snapped the crank and left little peace's of piston threw out the whole engine. My question is do I get a spool forged kit or bolt a egas engine bottom end on a turbo head which everyone keeps telling me to do? I know I'm a dickhead for not asking for evadence of the bloke buying the parts he said he put in the engine but after the test drive not getting tracshion in every gear I had to buy the car
