Time to give him a call.

well... If I want to keep it boosted (which I do) then another hi compression motor might not be a good choice. I can pick up a cheap 4.7l here for next to nothing and use the high-flow euro heads and SCer and should make some good HP. But yes, I want knock detection. Will look into the Vampire system when I get that far.

Andrew, Vampire is the ticket! I run one in my twinscrew track car and I can say it works! I can adjust how much timing it takes out with each lbs of boost and it can retard up to 20 degrees based on the knock sensor that you mount in the valley. You can also have it retard all the cylinders or individual cylinder that is knocking.I also have the knock monitor so I can see when the car is knocking and how much timing is being taken out when it does,and in individual mode, which cylinder is knocking.

Man I gotta get that 87 head/S3 bottom end motor together to show people. 12 or whatever CR, and boost. That would be wicked.

Andrew...the car looks great. Glad to see you in to it now. Spending time with the kids is time well spent. They grow up so fast. It will feel like overnight at some point. It did me for sure.

J&S Electronics makes 3 systems. The Universal, The Intercepter, and The Vampire. I have The Vampire for my 85 stock ignition 32 valve engine. John at J&S is very familiar with the 928 and will put the whole system together for you. Louie Ott has the same system on his monster motor and recommends them very highly which helped to make my decision. After doing so I am more than pleased. It is simple to install and very easy to set up and use. You can adjust how much retard per lbs of boost and if you have a sharktuner,you can also datalog the amount of retard the unit is taking out so you can see if your engine is knocking and when and how much. I wouldn't run anything boosted without it. Insurance is good!

Good News and Bad News...
Thanks to Rhudy (Camboinc) for letting me drive his Panamers GTS. I also got to pop the cherry on the launch control on the car. Ohhh BABY! That car is so much fun to drive. If you have the means... I highly suggest you pick one up! It is so choice!
So Rhudy pushed me to do the leakdown test. Thanks again homo! Interestingly all the cylinders were pretty close. Between 25% and 35%. Not great, but not horrible either.
First the good news. I've finally gotten a bit of tune on it so that I can drive it around the block without it dying. I took too much out of the cranking and warmup map so it's hard to start cold, but once it starts it idles great!
The oil smoke out the tail pipe is clearly from the oil breather setup (What a cluster f***). It's plumbed to feed the output to the exhaust. I think this was done for the Texas Mile run that Ed did, but something has gone wrong with this setup and it's now just spewing oil into the exhaust. I think one of the issues is that whoever did the install used heater hose which is not rated for oil... so now they are all super soft.
My plan of attack is to remove all that stuff, cap the exhaust ports, and install a provent to control any excess crank case pressure and return any oil back to the sump (like I do on my GT). I just need to get some plugs for the heads to un-install all the mickey-mouse BS oil breather crap that's on there.
OK now the BAD NEWS!
Cylinder number 7 is badly scored! The leakdown confirmed that the loss was through the rings (or maybe the cyl wall). And many of the pistons are in really bad condition. It is clear this car was knocking really really badly. Evidence below...
Cylinder #7
Another view...
One more...
Cyl #3(?)
Cyl #6
Cyl #4
So now the decision is what to do. In my opinion, this motor is toast - but drivable for a while. It might last a week or maybe a year.
I'm thinking I will get it tuned up a bit more and fix the oil-breather crap and then drive it. Meanwhile I will source a new motor. The only thing that might be useful on this motor are the heads.
Thoughts?

Hey Andrew,
What boroscope do you have? I want to check how much carbon buildup I have on my pistons, etc?
Thanks,

So the decision has been made. I just purchased a US 4.7l motor and will use whatever I can off the Euro motor to build the US one (heads are hopefully in good shape, cams too). With the lowered compression, we should be able to crank up the boost a bit more - or at least not worry as much about detonation.
Still haven't decided on e85. Part of me wants to, but I would like to be able to drive it to SITM or other destinations and am a bit concerned about availability and range. I've got time to think about that.
I've got some concrete work in the garage that needs to be completed before I can yank the current motor, but I suspect the motor will be out by Christmas and then we will start the rebuild process.

And here is a link to the camera I used to look inside the engine.
