    the engine fit without any issues, didn't have to relocate anything, coils fit fine, removed the heatshield since turbo went, but it would have fit fine too

    1985 Buick GN 6.0/4L80

    everything is from www.brphotrods.com, including the headers. a friend of mine did the installation, but i believe it was as "drop in" as any kit can be. they had some concerns about the 4l80 tranny and crossmember, but we didn't run into any problems, headers worked great too. Solid kit...

    These vents don't seem like a whole lot, but when the electric fans come on... Whoa! Couldn't figure out a way to get heat out from under the hood, this was a great idea by a buddy of mine who does really great body work.

    Blackbuick1987, there is a linkage that goes to the tranny, but it is an electronically controlled transmission, puts the "e" in 4L80E

    My Turbo 6.0 LY6 4l80e build

    Where/how do you have your pcv valve setup? I've heard and read so many different things from people running turbos and superchargers and spent the evening working on mine. That's crazy you burnt your wires, more so that you don't have a hood on! I had problems with underhood temps, and I'm...

    1985 Buick GN 6.0/4L80

    It's been a while since I've given an update, work has been busy, but the GN project is going well. A Procharger unit was installed on the 6.0 and I'm still working on getting all the bugs out of the system. Along with the install came another fuel pump, injectors, radiator, fans, hi-amp...

    A newer compressor off of a 90's pickup along with the Holley a/c bracket (https://www.holley.com/20-131.asp) was used. Heater core went bad a bit after startup, that was swapped out as well.

    I have about 400miles on the new engine in my GN. I am getting this trouble code, I've been told by other mechanics it's because my o2 sensors are located at the header collector and not on the manifold, and that a custom tune will take care of it. Problem is that getting a custom tune is a 3-4...

    I will get better pics of the rear as soon as the south Texas weather clears up. Only very slight rubbing on front pass. side when I hit big potholes at higher speeds, but I've had had the same problem with two other gbody's in the past.

    I've been a visitor on this forum for a very long time, reading and learning much. I thought I would contribute a bit. I've owned my '85 GN for 7years. I'm 32 now, but a GN had been my "dreamcar" since I was 12 and would see them run at the local track. My plan was to keep the car as original...
