That’s them! Media blasted twice then buffed up with the flap disk and dremel. Coated with zinc based primer, cast iron engine paint and clear coat that’s used for wheels. 
 

 

:laugh: media blasted twice. I'm surprised those didn't needed melted down and recast. They look great. I'm watching this big brake setup take form since it's very nicely documented. Looks to be much easier than the wj and for running 32s on 5.5" lift xj and mjs, this might be a sweet easy mod for guys without going deeper with fabrication.

Agreed. The outer circumference of the unit bearings needs to be shaved to fit the rotor but it’s not too bad. Several small parts you have to track down for the swap. It’s nice to use off the shelf components though. Easier to replace if needed while on the road.

Finished up one side today. The caliper and bracket do both require some flap disk work. You’ll need to take off about 1/8” of material off of the caliper and bracket. I’m using the late 99+ style unit bearings and only needed 1 washer on each caliper bracket to center them up. The washers were .10” on the dot. Test fit the turbines. I need some NOS center caps for these wheels. They are just too nice to clap on some old center caps. 
 

Also finished restoration on a rear prop valve. It’s going into a parts collection of top shelf parts for something in the future I suppose

Front axle is finished. Body work to begin next. After a few hours of cleanup :laugh:

 

13” rotors, massive dual piston calipers. It all fits a turbine wheel so long as you use a 1.25” spacer and are willing to grind down the bracket and caliper some. A 1.5” spacer will probably let you just slightly grind the bracket down. The calipers do look much better with the casting marks removed though. Calipers have been clear coated as well. I will say, it’s quite a bit of brake when you look through the turbine spokes :L:

 

This is about as “ultimate” HP30 as I’d built for this particular MJ. There is a bit of weakness at the inner C’s that was addressed with the gusseting. Lower control arm brackets are now greatly reinforced with skid protection. Passenger side upper control arm is significantly stronger due to the gusseting. Track bar mount has been replaced with a nice 3/16” bracket welded in place. The 3.55 gearing is as deep a gearing as one can go while still keeping the large pinion. For 31’s and the LS1 this will be a great combo.

Here are some problem spots I recommend addressing for water intrusion. Just below the hvac blower, below the bulkhead connector, and into each rocker panel opening from the wheel well. 
 

Wheel wells and the underside or the front frame rails are now coated with raptor liner.

I'm curious to see the various foams you selects for the HVAC rebuild,a d any other details of the HVAC rebuild.

I’ll gather the part numbers for that. The thick gaskets are 1” minicell 2lb foam. Inside the box the lining is mostly open cell foam 1/8” thick. I assume that may be more of a sound baffle than anything as it offers little insulation. There are a few other seals such as those around the heater core and ac evaporator. I have ordered the replacement thick foam already. The gasket that goes around the ac evaporator lines is specially molded. Fortunately mine was in excellent shape. The open cell foam lining inside the box was also in very good shape and will be thoroughly cleaned with a mixture of simple green and the water.

I wish I could find someone with the talent and dedication you have in my area.  My truck needs some attention and body work/metal work is not anything I want to attempt.  You do house calls?  I'll fly you over, lol!

 

Great work!

Much appreciated. I’m considering doing custom MJ builds in the future actually.

On a side note, picked up a vibration tumbler setup with abrasive media to clean up hardware. Grabbed it at harbor freight. Works exceedingly well and lets me reuse a lot of oem hardware which, in many instances, is better quality and fit than what one finds on the shelf.

Motor mounts and track bar mount are in. The frame rail at the track bar mounting point has been heavily reinforced as I’ve noticed it to be a weak point. 
Dynamatting the interior and rebuilding the hvac box. Also mounting the hidden winch and steering brace setup. I’ll be running a RedHead 12:1 steering gear with a 35lb valve. The goal is to have rack and pinion level steering precision.

Hvac box restoration in progress. I add a lot of extra sealing around these plate and fin evaporators. There is no room for the blower to throw air around the evaporator now. All the seams have been sealed up. Made replacement gaskets for the air intake and the firewall seal. Also added a 1/8” minicel gasket to the blend door on each side. The hvac should function better than factory when I’m finished.
