I've gone down the rabbit hole of top end work, satisfying preventative and issue-addressing maintenance.
Had an intake leak at the supercharger (tip-don't pull it with your tiny wife as your only helper, it is NOT easy to re-seat correctly), so I finally got a decent engine hoist to pull that sucker.
What better time than to upgrade to a 580 blower?
So in goes the 'new' 580 blower, new supercharger oil, intake gaskets, valve cover gaskets (leaking slightly, original at 150k), spark plugs, wires, one new coil (corroded), and 550cc injectors (already have the map from Tony). I've pressed out the bearings and middle spacer of my 77mm pulley, bringing the spacer to a machine shop to shave down. Even without any shims the clutch gap is over 1mm, hoping to get it within factory range.
Last year I did the bypass valve, MAP sensor, IAT sensor, and breather hoses.
Question - Am I missing anything? I'd hate to put this back together and smack myself on the head for forgetting something that would be way easier to address now. The only other thing I can think of are the knock sensors but searching it doesn't seem like they ever go bad so I'm planning to leave them be.
Also - should I not use anti-seize on the spark plugs? I've always done this on other cars in the past, but swear I read somewhere recently it wasn't recommended (and the plugs I pulled out didn't have any, just oil on the threads...).
Now is a good time to install the Nitrous system.....you know for preventitive maintenance. LOL
But really the best advise I can give you is really take your time. Look at everything over and over. Make sure NOTHING fell into the intake ports . LOOK in them to make sure. Recheck everything as you assemble. Use a torque wrench !
