Im trying to think of everything I can do to rebuild my z6 and other upgrades for my car. Heres what I've come up with:
please add any other ideas.

New/preformance...
cam
cam gears
intake/exhaust manifolds
cai
new cat/exhaust system
clutch
flywheel
pully kit
pistons
rods
fuel pump
fuel rails
fuel injectors


bore out:
manifolds
throttle body

thats all I can come up with right now

And I now that doing ALL of these upgrades is unrealistic, but im just trying to know everything I can do with my new engine before I drop it in.

 

port n polish the head. new valve train and a 3 angle valve job. by bore out do you mean port matched also?
