    1990 760 idle issues persist

    I made a thread a while ago about having an idle issue with my 1990 764t. The issue is mainly present when the engine is warmed up. In gear, idle is around 950, in park it's around 1600 steady, or 2000rpm for several seconds, and then it cuts out like it lost power until around 1000rpm, than...

    No spark after breaking in IPD cam

    Got a good one for you guys today. I?ve been sitting on an IPD turbo cam for a while now and finally decided to install it. Since it?s close to 100 degrees today, I decided to do the break in procedure while driving on the highway, I was able to get the 20 minutes of 2-3k rpm. Everything was...

    Conrod question

    So Monday my motor started knocking, Tuesday it officially crapped the bed. The conrod bearing on the crank end let go, letting the piston slap around in the cylinder. It ended up popping the freeze plug, breaking the cylinder wall between cylinders 1, 2, and 3, and the piston separated from...

    Valentine?s Day head gasket

    1990 760 with a b230ft. Got to work and noticed smoke from under the hood. The car hadn?t overheated or anything like that prior to me parking. I popped the hood and saw coolant spraying out of the seam between the head and block on the exhaust side, close to the front of the car. I?ve never...

    Brake light help

    So I just discovered while backing into my parking spot at home that none of the three brake lights are working in my 1990 765. I?ve checked just one bulb and it was good, and I?m assuming (yeah I know) that the others are good as well. Weird part is, my bulb failure light isn?t illuminating...

    Ezk mod question

    So I?ve been digging around and have come across some info on ground pins 18 and 19 in the ezk to advance the timing. I?m no master with electricity, so I?ve got a fairly simple question. To ?ground? these two pins together, do I just have to run a wire between both terminals, or do I run a...

    So I?ve been doing research for a while now about water meth injection with the plans on getting it installed. I?ve had half a system installed on another project, and decided to swap it over to my 1990 760 turbo wagon. The half installation was my most experience with this kind of thing...

    Kinugawa woes

    So I?ve slowly but surely been quietly building up my 1990 765 turbo. In the process I managed to find a 95 850 turbo in a junkyard and snatched it up. My goal is/was to push the 15g for all it?s worth. I purchased a 9 blade turbine wheel from someone up in VA, and purchased a billet 6+6...

    Couple g80 swap questions

    So I?ve been doing a fair amount of research on swapping a g80 into my 90 760 turbo wagon. The I?d sticker is ineligible on my car, but research and a one wheeled burnout tells me that I?ve got a 1031 axle. On my latest junkyard trip, I grabbed a g80 diff out of a 93 940 na. Now most of my...
