I just ordered some parts for my R53. It's at 104K, Just bought it a few weeks ago, it's a daily driver. It's apart in my garage (checked the super oil). I'm installing these parts:

DDMworks Intake
15% Pulley
Belt
-1 Plugs

Thermostat and Gasket
Thermostat Housing
Water Pump
Water Pump Oring
Samco Coolant Hoses Cooper (blue)
Brass Coolant Bleeder Screw

Did I forget anything?

 

New belt tensioner, Supercharger Inlet Gasket, Supercharger Outlet Gasket. Then I think you have it all covered if you have the SC off and changed the oil.

 

I am getting ready to do the same, oil is on the way, wmw pulley package 15%, except no one got back to me about pully puller tool rental. Does anyone know if hf has one that will work? And a cheap mod for mfe removal tools? Is there any must haves that r relatively cheap? I need to do this this weekend and have a low budget right now!

 

Crank position sensor o-ring.

 

Way will rent you one http://www.waymotorworks.com/pulley-puller.html
On his website when you buy the pulley "This tool can be rented for free with purchase of our WMW supercharger pulley."

 

Ok I get to spend some more $$

@Braminator
Is a New belt tensioner vital?

@JAB 67
just ordered one!

 

Its more like preventative maintenance since you will have it all apart.

 

Halfway done! Waiting on my hoses!

 

Goodluck, Its kind of a PITA DIY job. Changed out my belt tensioner a week ago.

 

As far as the supercharger oil, your local GM dealer should have, same sc as GM uses. I picked up some last week for $7.72 (have a friend in parts dept.) list was $12.42 for 4 oz. Used 5 to 6 oz.
