Since I'm not what you'd call a "prolific poster" here (also, the blowup happened on 3/28), many of you might not remember this: 
Well, it turned out that pretty much the whole driver side intake tract was filled with oil: 
... and my DS turbo looked like this (note the bent blades): 
Turns out shaft play was around 30 degrees (total). Later on, I found the remnants of the old bronze bearing in my oil pan. Go figure. Unfortunately, I found that I also had no compression in #5 cylinder. Of course, that meant that, in addition to new turbos, I needed an engine rebuild too. This turned out to not *really* be the case, as it was just that the exhaust valves/seats in that cylinder had burned a bit, but I went ahead with new pistons, rings, and valvetrain anyhow. The rebuild was fairly mild by most standards - stock rods, stock bearings, stock oil pump, ARP hardware (main studs, rod studs, head studs), .5mm larger Wiseco pistons (ceramic coated and dry film lubed by a local shop), stock valves, and cometic MLS headgaskets. 
If I had to do it again, I would have used Kyle at IPP. It was foolish of me to think I could forge my own road and end up with a less expensive, as reliable package as what he puts together. I'm happy to have supported some of my local businesses, though. So, to support the new engine, I needed almost all new support systems: turbos, intercoolers, hardpipes, fuel injectors, etc. I ended up going with Z1 GT600R turbos, Nismo 740cc injectors (w/adapter set), Z1 SMICs, their "street" clutch kit, all new timing components (idlers, studs, tensioner, backing plate, belt, water pump), new AC O-rings all around, and just about every air and coolant hose I could get in silicone. After lots of money, and lots of time (fast forward to about a month ago), I was here: 
Then, in a fit of productivity, I brought it forward to here: 
Shortly after that, we started it for the first time (after cranking it for a few minutes to get oil pressure). It ran almost perfectly, save for me swapping the VTC and det sensor plugs (which blew my 10A engine control fuse). I owe all of that to creative searching here at TT.net. I literally *could not* have done it without the collective knowledge here. After one more minor setback (the positive lead down to the starter was so corroded that 12V at the battery became 7V at the starter), and some shakedown vacuum leak correction, I'm slightly afraid that I might not have enough tire under it anymore. Sucker pulls like a freight train, I haven't even seen full boost yet - only about 5PSI, as I'm only 32 miles into break in, and those turbos sound awesome compared to the stockers.
Your powers are useless! I'm wearing my tinfoil underwear! |

Big thanks to TT.net -
