Re: Ken's '91 Fastback Resto/KA-T Build
No, I had no luck with Andy's. They told me I bought them from one of their sister companies Sport Compact Only (which i knew was a lie) so I called them and they redirected me back to Andy's. After a couple long very frustrating phone calls I sold them to a local guy and just ate the price of shipping.
I ordered a new pair of Origin Lab pull type overs from a different place and they are great. Nice gel coat finish and they fit exactly how they should.

Re: Ken's '91 Fastback Resto/KA-T Build
Removing that dampener helped to get the slave cylinder bled with the quickness. About 5 minutes and I have a nice pedal.
I took it down off stands and put it out in the large bay which is more ventillated and adjusted the fuel pressure and timing. Got the pressure down to where it needs to be, and the timing is set at about 20* BTDC. It will sit and hold idle at about 1000rpms and revs nicely up until about 3500-4000. At this point I do not see the boost gauge moving at all, no air from the BOV, but I can hear the turbo whistling a little bit. I took the rpms up to about 4k once and it belched out a lot of black smoke then died. Tryed to start it back up, but got nothing. I pulled the plugs and they are black with fuel, so I'm going to let it sit and air out then get back to it.

Re: Ken's '91 Fastback Resto/KA-T Build
Its been a while, so heres a quick update on whats been going on lately for anyone that may have been following along...
It would sit and idle nice and smooth, but I was getting a 10.0 AFR at idle which would lean out to about 12.0 at 3k RPM. After running until it was almost up to normal operating temp it would start to spudder and eventually die. Plugs would be soaked, and some fuel would make it to the oil pan. I really wanted to get in to troubleshooting this problem, but came across another.
Right before it would die out, after the temp had risen some, my oil pressure would steadily drop down. At cold start it sat around 30psi, then would slowly drop and the lowest I let it get was 8psi, so it was impossible to let it run long enough to figure out why I was running rich without possibly destroying the bearings. The culprit was the top hat shaped O ring seal between the lower timing cover and block. None of my gasket kits included one so I reused the old, and apparently oil was running straight down the front of the block back in to the pan. After buying a new seal and comparing it to the old, the used one definately wasnt sealing good enough.
Tried replacing the seal with the engine in the car, but after fighting to squeeze the oil pan out for a good while I decided to just yank the engine back out and make it a hell of a lot easier to work with. That is the status as of now...I am hoping to get everything cleaned back up and put together tomorrow so I can get the engine back in by next week. Gotta love it...

Re: Ken's '91 Fastback Resto/KA-T Build
The engine is back in and running nice. The oil pressure does not dip low like it did, and it is not running anywhere near as rich. While I had the engine out I went over it thoroughly and found two things that may have contributed to the problem. One, I made a gasket for the AAC valve out of cork paper and it looked to be very cracked up and brittle already. When I unbolted it the paper crumbled away, so I think it may have been leaking there. Made a new gasket with thick black paper and RTVed it good.
Two, somehow I missed the angled vacuum port on the bottom side of the throttle body so I capped it off. Now it idles good, I had to mess with the idle screw on the intake manifold and on the throttle body to raise it up some but now it sits at about 750rpm.
The strange wideband readings were because I had the wideband wired up to the narrowband wire from the control unit. I rewired it this evening, and in the morning I am planning on recalibrating it, putting the dash back together and seeing what I have. It will idle strong without choking up and dying now, and after pulling the plugs they are not wet like before. Hopefully I can drive it tommorrow!

I just caught up with your build. Looks awesome.
Definitely explains the importance of having gauges and monitoring devices. Imagine if you didn't have the oil pressure gauge....

Nice build just curious on any updates?
