    1988 G30 Cube Van, A blank canvas.

    The info I got on the 4l80e conversion is in this thread, posted above. As for hooking a TPS to a 6.2, that remains to be solved. I think the solution you propsed is logical. I was thinking that maybe an entire throttle body could be pulled off something newer and bolt on to the 6.2 if I could...

    Currentyear best bang for buck solar panels?

    Haven't had to shop around for solar panels in a while. Looking to purchase a 6-900w system. Last time I looked, there were some big time deals from China, of course, but they were largely untested.

    1988 G30 Cube Van, A blank canvas.

    Got some info on the cattails for everybody who is curious... I did some basic testing with the down today. I took some leftover fiberglass insulation and sandwiched it between two pieces of cardboard with adhesive. I did the same to an equal amount of down. I then took an electric radiator and...

    1988 G30 Cube Van, A blank canvas.

    I generally share the sentiment that putting products that were never intended for prolonged exposure to humans in your tiny living area could be a bad idea. Bed liner is probably fine after whatever solvent it contains has dried off, but I learned earlier this year that I am extremely allergic...

    1988 G30 Cube Van, A blank canvas.

    I've got a couple theories on insulation. I'll probably end up using XPS because it's cheap and simple and it works, but I'm open to other ideas. I happen to live near a very swampy area full of cattails. I had half an idea to try and use cattail down to insulate the van. Yes, I understand that...

    1988 G30 Cube Van, A blank canvas.

    Forgive me for the brief words in this post I'm posting from my phone. A couple things: - I've decided rather than trying to chance the diff gears I'm going to swap in a 4l80e. I need to remove the transmission anyway to do the rear main so that's sort of nice I guess. The 4l80e only needs...

    Changing diff gears...

    I definitely agree with the greasy geek sentiment. In the age of the internet, really it's not about what you know, it's if you can find what you don't know. That turbo Winnie is fantastic. I think my favorite part was when they decided to just keep adding fuel filters rather than clean the...

    Not sure if I think dropping 600 bucks for a tamagachi that makes the 4l80e work on my truck is something I can live with.

    Came up with a list of things I'm looking for at the junkyard when I got to check out the axles...

    Changing diff gears...

    Well I just called my local (well fairly far unfortunately) junkyard and they have two 1 ton GM 14 bolt axles. I think before I buy the ring and pinion gears and, as I've now learned, 200 dollars worth of bushings and bearings plus some tools I don't have, I'm going to see if I can just swap on...

    Changing diff gears...

    No turbo. I think doing a turbocharger conversion would be more complicated than just putting in a different engine no? I'm not really into putting a turbo on an engine that was never designed to have one. I know since it's diesel it's more reasonable to do such a thing, but I'd rather not have...

    1988 G30 Cube Van, A blank canvas.

    Thanks for your replies to all my threads. They are helpful. - Yes, the paint you pinned down is what I'm looking for. I think the vehicle will look good with a military look... plus the light color will help with heat absorption. As well as camouflaging it when the nuclear holocaust finally...

    Changing diff gears...

    I'm going to say it's 7 combined. It's definitely under 10. I will test later this week on flat ground with a combination of highway and stop/start miles. I agree that the best fuel mileage is going to be at lower speed because of the cumulative effects of poor aerodynamics. That unfortunately...

    Changing diff gears...

    I don't think so. To be honest I'm not exactly what sort of fuel mileage it's getting. It just feels like I can watch the mileage go down. Later this week I will go out and test to see for certain what I'm getting.

    Here's a fun one for you all...

    Just went out and took a look: Yes, I think your correct. The lines that run into the floor from the blower housing run up into the disconnected compressor under the hood. All the lines are custom cut rubber with fittings so therefore I don't see a sight glass anywhere.

    Here's a fun one for you all...

    Do you mean the compressor under the hood attached to the engine? If so, it's been disconnected since God knows when and is indeed quite rusty.

    1988 G30 Cube Van, A blank canvas.

    This is going to be the main build thread for this big blue (maybe not for long) van.  Van is a military spec G30 with a 6.2 detroit non-turbo diesel motor paired to a 3 speed Hydromatic. It sounds like an old school bus. I have a small list of various things so far that I'd like to do that...

    Changing diff gears...

    According to my calculations based on 10 teeth on the pinion and 41 teeth on the ring, this differential is at a 4.10 ratio. That explains the 7ish mpg! What an absurd gear ratio for a vehicle like this. I suppose this is our tax dollars at work. Although I can't fault the absolutely heroic...

    Here's a fun one for you all...

    So awhile back I bought this mil spec G30 that came installed with this non-functional 12v air conditioner pre-installed. It's a product produced by a company called Frigette, which of course is no longer in existence.  However, parts for this cooler seem to be readily availiable via...

    Changing diff gears...

    Resurrecting this again... As you can tell I move slowly on this stuff. Mostly due to winter being a terrible time to do anything constructive up where I'm at. I suppose today I'm going to start thinking about cracking open the rear diff to get a look at what gears are in it. Will report back...
