The little things

Have been working on the car some this summer. My son and I made a new gas flap. That was a fun project we could do together.

Alternator rebuild.

The alternator had excessive wear to the slip rings, bad regulator, and bad front bearing. I tore it down, bead blasted the case, tested the diodes, cleaned and re-coated with red electric motor varnish. Painted the housing with satin black VHT brake caliper paint, baked at 400 deg. Replaced bearings, replaced slip rings and regulator and assembled.

Rust engine tin needed some attention.
Rear most tin over the turbo had some rust holes. This resulted in another father son project to make a few patterns that I will cut out and butt weld in.

Acid

The rest of the engine tin I stripped, and prepped with phosphoric acid. Painted it all with satin black VHT brake caliper paint and baked at 400 deg.

Boost

I took apart the turbo. Lots of burned up oil, but all the internals look good. It's boxed up ready to be re-balanced once I decide who to send it to.
Found a NOS rebuild kit that will be going in after balancing.

More VHT

I carefully masked off the compressor housing and bead blasted it clean. Painted it with silver VHT brake caliper paint, and baked at 400 deg.

I'm wondering if son is going to inherit this car when Dad gets alzheimers down the track and another project thread starts. Like 'I remember the day dad bought this car home and helped him restore it"

Great car and thread.

Just curious do you plan to leave the car paint alone or a repaint? I get mixed ideas...some say never paint it, leave as is original. Others say it has too bad of a paint job, and others try to blend the paint, leaving as much original.

I think doing mechanicals is first.

Paint

I plan on getting the car running and driving before repaint. In my opinion this paint is too far gone to consider saving. I will cross that bridge when I come to it. It may be years before I have to worry about that.

Splice in extra wire to the Alternator.....

Before I re-installed my alternator I spliced in extra wire to the harness so I would have an easier time getting at those small shroud nuts... BTW Nice work.

Turbo Rebuild

I am trying to decide how to proceed with the turbo rebuild. I sourced a NOS KKK rebuild kit and had planned on building the turbo back myself. I am now leaning on sending the parts up to Tim at Tim's Turbos - Turbocharger Rebuilding and Sales
Anyone have a comment?
See closeup of the tag on the rebuild kit. A couple of people have asked where I got the rebuild kit. It was on ebay, not listed very well and I snatched it.

Your 3k rebuild kit has a 270 degree thrust bearing which is standard. Thats what comes in them from Borg Warner.
A 360 degree thrust bearing has more surface area and is more durable. It also has better oil control. Durabilt Turbo upgrades these turbos with a 360 degree thrust bearing when rebuilding them and then the assembled cartridge assembly is high speed VSR balanced.
I'm sure the place you mentioned does a good job too and maybe you can just mark the turbine wheels with a sharpie pen and reassemble it yourself in the same position it was before you took the compressor wheel off.
If you want reliability with a warranty I'd send it out. If you want to try rebuilding it yourself maybe it will work.

How does the shaft look under the blue masking tape? If it's blued from extreme heat towards the turbine wheel end it might not be perfectly straight anymore. If it's scored from coked oil and the piston ring grooves are eroded it's probably no good anymore.

Good luck with it.

I am getting ready to paint the fan and housing. I have been reading up on magnesium and how to prep for paint. Here is the recommended prep procedure I am following. Caustic wash parts in hot water. (ph greater than 11) I used half and half mixture of TSP and TSP PF.

The parts were already as clean as I could get with solvent parts washer, and washed with soap and water.
