Thanks! My actuators are working fine, just a bit rusty. I may just epoxy coat them and roll with it if I can't find any NOS.

You’re welcome and best wishes. I have a bunch of NOS parts to get rid of and will try to post them soon. I think I have about 6 actuators, but I know you’re trying to get your project wrapped up now.

Thanks! Will be interested in your "inventory"!

Got the numbers back yesterday on flow test of assembled and ported Plenum and Injector Housings. This was with a Superflo 1020.. we checked cylinders 4 & 5..

Cylinder 4 Primary 174 cfm
Cylinder 4 Secondary 178 cfm

Cylinder 5 Primary 173 cfm
Cylinder 5 Secondary 176 cfm

Total flow both ports open

Cylinder 4 - 352 cfm
Cylinder 5 - 349 cfm

Trouble with removal of one torx screw on one TB blade. Got it out, but will need to retap and possibly use slightly larger screw. For those who decide to tear down their TB for porting or as in my case, powder coating, be aware of the spot welds on the ends of the screws after they are installed! Locktite would have been a much better method than this!

Pulling brake booster to remove last two driver side cam cover bolts so I can get everything out to powder coat next week..

Well pulling the brake booster was a major PITA! The lower two lock nuts are "relatively" easy to remove, but the upper two require dropping the steering column and removal of the cruise control vacuum can, ECM, etc.. not a job for the faint of heart for sure.. passenger side is simple, just remove the evaporator coil cover near the firewall.

I used an impact to remove the Torx 40 cam cover bolts. This was easy, none of the bolts gave me any crap. Had to remove a few with a long handle 3/8" flex head rachet. I bought a set of "stubby" Torx 3/8" & 1/4" drives as well.

Cams look very good. Very light polish on the lobes. Prepping everything for powder coat..[ATTACH][ATTACH][ATTACH][ATTACH][ATTACH][ATTACH]

Helpful hint:
Take the driver's seat out, 4 nuts and a
couple electrical connectors. Makes working under
the dash MUCH easier!
Besides, no telling what you'll
find there...

Thanks! I've done that before.. I had the car on my lift so that I could stand at waist height and reach under pretty easily. The issue for me was gaining access to the top two nuts. I literally could not get a rachet anywhere near them. Dropping the steering column let me get a straight shot with a LONG extension and a deep 1/2" socket..

Everything headed to powder coat this week!

Looking good Steve. I remember doing my first Z that way. It was a pain. I actually think it was easier to just pull the whole engine.
