for the bearings just take block, crank, and rods to a machine shop and have them take care of that for you, its just extra assurance with them taking all the specs and matching the bearings up.

Why are you looking to bump the compression up to 9/1?

Just leave it 8.5/1 and run more boost

I'm doing the same thing, I just got my cp pistons, eagle rods, and arp studs

Just brought everything to the machine shop and so far I'm lookin at 750 for bore, hone, align hone, deck, hot tank/block prep

well i dont plan on running a bigger turbo for a long time if i ever do and when you see car done up with big hp numbers the compression ration is always increased so i fugured why not go to 9 and stay with the turbo i got as long as i can run on pump gas and all my machine work is going to be done for more then 50% off my buddy can do side jobs on saturdays
