Hey fellas. After some opinions if you wouldn't mind.

Currently have a k20a2 ep3 type R with pt5558 and sidewinder on an oem unopened block. Totally stock.

Currently most I run is 1bar of boost on very rare occasions. Usually run 420fwbhp max.

For piece of mind I'm thinking about forging a spare block.

What is needed, what is worth just doing whilst your in there working on the block, and what isn't needed?

Currently on parts I have ready to go are 86mm 9:1 wiseco Pistons and eagle rods. Is upping to 10:1 compression worth it?

Plan was to use oem bearings, super tech valve springs and retainers, oem valves, replace valve guides and seals, oem sleeves.

Hoping for an extremely reliable setup, around 500-550fly hp and let the engine make whatever torque it wants to.

I know you guys in the U.S. Run that sort of setup on stock blocks.

Any thoughts on the plans? Criticism welcome.

Thanks
