Oil pump I wouldn't necessarily replace it. Open it up check for wear if it's o.k grease with redline and refit.

For that power you will need arp head studs as well

Get the crank assembly balanced also whilst it's all out

[euro_urs4]

already have arp head studs, should i also get arp bottom end studs,

I did on my build but the OEM bolts are very good also so it's not a must do. They must be replaced either way as they are stretch bolts.

How much power can stock pistons take?

It depends, but i think that 500hp is safe , there are user runing 700hp with stock piston, on e85 , and with good software.

i run stock pistons, skimmed down. scat rods, new rod bearings. original crank ones. original rings no honing of block for changes.

i didn't remove the crank. i left it in.

even with just the rods and pistons weight matched the engine feels better for it. also the pistons a little lighter for it too.

have had no issues for 2 years running. 20k miles. currently runnnig 1.9bar on sc6152E. you can guess the hp. i wouldn't know but its pretty fast.
