Prepping an sr20

[import_racer87]

95% of sr20s look like hell right after they have been purchased. who even knows where they have been. what exactly needs to be changed from when you purchase the motor, to when its ready to go into the car? im guessing the usual spark plugs, distributor, plugs, injectors, check the the rubber hoses, etc but heres where i see the dilemma. those engine have been sitting, non running for so long, i would think the intake mani. would be filled with dirt, the cylinders would be all gunked up and you couldnt just replace the stuff and fire it up because u'd end up with a fucked up new again. i could be wrong on this but give me your opinion.
