need good crank kit for 2.5Turbo 92 spirit, any ideas? anyone done one?

[92spiritT3]

well come to find out, the engine has a knock to it. not sure the extent but going to take it for a ride down the road to see how bad.most likely going to need a crank kit. any ideas on a good kit? its no major damage because it isnt very loud, but going to really find out when test drive comes around. how hard is it to do? what all is involed.

any advice would be great

thanks
