Impreza GC8 piston and rods set...

Hello!
I have an na-turboed ej22 phase 1 from a 92 legacy swapped into a impreza, now I need to rebuild it and I was checking out options on parts. I really, reeeaaally need your help on this!

all the internals were stock, and now there is a rod knocking... Id like to do things right this time.

Would this setup be ok?
JE PISTONS: SUBARU EJ22 97mm 8.5:1 (314350) link
EAGLE H-BEAM ROD: SUBARU WRX 1.8L 2.0L 2.2L 2.5L (CRS5137S3D) link
Which road bearings should I get?
Is anything else important that Im missing here? I was thinking on a 11mm oil pump, then I read it would be a bad mod.

Other mods it already has:
GT exhaust w/custom uppipe, Tial external wastegate, td04 @10psi, watercooled
front mounted intercooler, aluminum piping, hks ssqv
apexi safc neo, innovate wideband, msd coils
lightened flywheel, and bigger clutch

Its kind of a daily (weekly..) car so I expect more reliability than power

I would look into a master gasket kit, and some arp head studs.

if you are not chasing big power, go with oem bearings. also, you dont need head studs if you are staying stock power levels.

if you plan on adding a big turbo and big power, then you need a whole lot more stuff.

all of your engine maintenance items should be done while the motor is out. timing belt, thermostat, spark plugs, etc.

dont go 11mm oil pump. they are for AVCS motors due to the extra oiling needed.

I've read about the 11mm oil pump, so I dismissed that. Is there any downside like that with the rod bearings? Like a faster wear on the crankshaft? Would oem rod bearings behave ok with the eagle rods?

I'm not chasing for more power, but I'm already on 10 psi with NA compression ratio. I'm afraid to lose the fun with a lower compression setup, right now it's faster than a STD WRX
