Well one last glitch I've been trying to work out is cranking. Sometimes it starts a little rough. While troubleshooting last night, the car just shut off and wouldn't restart. Narrowed it down to loss of spark.
Shane was nice enough to lend me the coil and ignitor off his SC300. Turns out my ignitor died. New one from a parts store is 300-400 bucks
So looks like I'll be checking the local junk yards
Big thanks to Shane for lending me the stuff!
Also, it looks like DB's dyno schedule is a bit busy, so I may opt to not get it tuned before doing the turbo, since it does seem to be running fairly well overall as-is. Bolted the turbo up to the mani today just to see if there is any clearance issues with the compressor housing hitting the manifold. It clears like this, so this is prolly how it will end up being aimed. I also put one picture showing it clocked to the point that it hits the #1 runner.
