First off I'll just list off my plans and then get onto the questions I have.
I have a 2000 Yukon 5.3, 4L60e, Auto 4wd (auto-2hi-4hi-4lo). Plan is to build my own 2-2.5" hotside with a 76 or 80mm turbo to a 3 or 3.5" downpipe connected to the stock catback (with a cutout), air to air intercooler, 50mm wastegate, no BOV. 80# injectors, upgraded fuel pump in the stock location, stock heads/stock bottom end/stock cam/stock intake. I have head studs in a package sitting in my garage and am planning on getting some good head gaskets installed in a couple weeks. Plan is to run 10-18# of boost on 91 octane with methanol (probably a progressive kit). I don't have really any questions on that side of things, but figured I'd mention where this build is going.
Now with all of this happening I plan on swapping in a 4l80 with a Circle D billet converter, HD shift kit, and otherwise stock transmission (this is going to happen before the above gets done). From what I have been reading the swap is pretty painless, but I seem to like making things more difficult than the really need to be. I really want to convert my Yukon to AWD with a 50/50 F/R split. Maybe even 30/70 F/R if that is possible. I would like to keep electronics out of the equation and just have a mechanical awd system.
I was orginally thinking it would be a pretty straight forward swap, find a silverado SS tcase (or similar) and swap it in. But I have read that I may have to swap the front diff and wire in some electronics and blah blah blah. Is there a good way to convert these SUVs to AWD without a bunch of wiring headaches? Can I just install an AWD tcase or will that tear up the front end? I know that GM makes an adapting housing & input shaft to bolt a Silverado SS tcase to the 80e so that part can be done.
My other option would be to bolt my stock tcase to the 4l80 but how long will that hold up? I tend to be pretty gently with my vehicles, but I still drive them the way they are meant to be driven.....if I have 18# of boost it will see it on a daily basis, but I won't do brake boost launches with it everyday but it will still get pushed. This option seems to be the easiest, but that doesn't make it the best option. I want something that will be fun to drive and I won't have to fix it every time I lean on it. I know that there will be some weak points that I will find at that power level, but I don't plan on thrashing it every time I take it out.
If you want to give your .02 or know of any good articles that I could study I'm all ears
