Replacing big end bearings

I am hoping to put new engine into my car but before I fit I want to fit new bearings as a precaution.what I want to know is can I fit bearings without removing pistons as I don't want to disturb them

No as such. As be wise to inspect the pistons. But yes could spilt the block and knock gudgeon pin out. Leaving pistons in. But surely be wise to inspect and put fresh rings on.

Would have all there from crankshafts. Bearings. All genuine Subaru Seals and Gaskets etc
