I decided that I was going to clean up the engine bay before putting the engine back in. After all the work I went through detailing the engine, I didn't want it to go back into a dirty bay! I had a couple holes filled in and had the body shop do some minor smoothing and then had them repaint it. The goal was to have a relatively clean look without going nuts with the filler to make it smooth. I dont want to have to work about cracks later.

While this was going on, I began the tear down of the engine. We took the head off and I decided to have it rebuilt with new lifters, guides, valves, seats, springs etc. After the head was removed we inspected the bottom end and were very surprised to find that it was in awesome shape. Cross hatching was perfect and everything else other than the chain guides looked like it had 50,000ks on it! A note to all, regular oil changes and maintenace will take these engines a LONG way!
Even though it wasn't necessary, we replaced almost every part with brand new parts. Water pump, billet crack pipe, thermostat and housing, all new seals, gaskets, plugs etc. Other than the bottom end, we replaced every thing.
I also prepped the block and painted it with high temp paint. I sandblasted every piece and every bracket and had it powder coated. Any components that were hot (ie. Hot side of the turbo, exhaust manifolds, downpipe, etc.) were all blasted and coated and baked with a Thermal Barrier coating to keep the heat from radiating off. All cool components (intake manifold, compressor housing, intercooler etc.) were blasted and coated and baked with a 'Thermal Disperssant' coating that helps cool the component. It took a while to do all this and was a pretty messy job, but in the end I think it turned out very good. The sad thing about this is, once it is all back together, you cant see all the work that went into it, however, just me knowing that all that work went into it allows me to sleep at night
I don't have any pictures of the tear down, but here is what it looks like all together minus the intake manifold...
