Default turbo engine build

I have a forged LS2 that was built for a supercharger and 600rwhp.
I'm going to run a turbo and want it to take 20 psi and possibly more.
The engine has about 9000 miles on it and has had lower oil pressure since
the first day it was started. Runs around 18-22 psi at idle and 40 higher rpms.
Oil pump o-ring has been checked and replaced and wasn't the issue. Anyway I'm guessing it has a little extra clearance and I've been running it with no issues other then oil pressure. I'm thinking of pulling the engine out and having it checked out before I put the turbo on. What should I have done to it? Here is the build specs

LS2 block
Stock crank
Eagle H beam rods 6.125
Wiseco K398X05 LS1 3.2cc Pistons 4.005 Bore
Wiseco GFX Piston Rings gapped for 600 rwhp
ARP Main studs
WCCH L92's Heads ARP head bolts
Harland Sharp rocker upgrade
Leading Edge Performance stage 1 blower cam
CR 10.4

I'm thinking of changing out the cam, head studs, LS9 head gaskets, rings,
bearings, etc. I'm running E85 and wondering if I should lower compression too.
I don't know if I should replace the crank and rods for something stronger.
If I go that route should I just stroke it for more cubes?
The crank has also been ground for a full length keyway. I'll either need the crank replaced or a keyway cut in a stock balancer as the Innovators eight rib isn't going back on. Any help or suggestions welcomed....Thanks

I've been in contact with a sponsor on here. I'm thinking of just refreshing
what I have, running a different cam, and head studs. The sponsor thinks the parts I have now will be fine but with just different ring gaps.

I was looking at those pistons also and that compression ratio with e85. are you up and running now?

Wish I could get my hands on a LS2 or L92. Have 3 6.0L long block cores but need to keep it on a diet.
