Ok I dont know the full story...But how bad is your engine????
Cheapest option would be to just throw some new pistons,rings and bearings in her.. Depending on how bad the crank is would need a linish and crack test atleast and maybe hone the bores
Just becasue you throw "standard items" back in doesn't mean it's not strong..It cant handle stupid power but a fresh rebuild sells GTRs quicker than a engine being put in that you dont know what's in inside it! Also while its open I would throw a sump baffle in it and the oil restictor in the head
This way you can sell off your aftermarlet parts as well..
