1971 Gold Metallic Project, The Turbo 1.7 Options

Running great!

I picked up this car late 2012 with the intention of flipping it. But never got anything done on it until I tore apart my Marathon Blue Metallic 73 to prepare it for WCR 2013, which of course didn't happen. So now this Gold Metallic 71 is my new driver.

Starting off at the beginning. Trekkor found the car and had it for sale. I picked it up from him without the engine, front bumper, rocker panels or wheels pictured below. Otherwise this is how the car came to me.

Put in the new spark plugs. Didn't notice a difference.
Installed a new CHT sensor so I can turn cold start enrichment back on.

Still fighting some pinging. Sunday I'm going to pull out 10 degrees of timing and just see if it's possible to make it stop. If that doesn't work I need to sit down and think about what's causing this problem. Could be that the spark plugs are still too hot. Could be that the MS is doing something odd or the coils I'm using aren't up to it.

I also found out (by actually looking) that my engine is 8.2:1 compression, it's a W code engine. This is higher than I thought, but comparing it to other turbo engines out there it isn't out of line. ottox914 is running ~9:1 and 12+ psi of boost. I have a feeling something more than just tuning is the issue. I honestly don't expect pulling timing to make any difference, and the AFR while pinging is 10 to 1.
