240z

Hey guys i currently have a L28 with P90 head on it but it's a N/A engine. It's got very low oil pressure and it sits just above zero on idle while driving it goes halfway up the pressure guage. I also found metal fragments in the bottom of the sump when I changed the leaky sump gasket over.
Are these metal fragments remains of a Piston/Oil ring?
Obviously to me the solution is a complete rebuild which leads me to a dilemna do I want ot revert it back to a Turbo engine using the P90 head or don't I? I've been told the head might not have been shaved but the pistons changed to give the higher compression. So I wanted to see how much I'd be looking at to rebuild the engine prep it for turbo and get all the parts.
At the moment I don't have thousands of dollars so am I better off rebuilding it how it is and reconditoning the head and block with new rings bearing and gaskets?
Thanks for any advice guys.

You might just be better off finding a L28 turbo motor in a boneyard and just swaping in the whole thing. It's a pretty common swap to do. I think it would be cheaper to find a good running L28 turbo engine, than to fix up your L28 n/a. Just my .02

You got a what with a what in it?
