It holds a brace supported by a socket spacer. OKIE for sure.

I had picked up a Banks turbo manifold for the 6.2/6.2 when I started this project. It will take a diff turbo and up pipe to work. So it going to get sold.

I just want this to run good is all, but need to clean up the setup. I have the GM4 turbo, not a powerhouse but it works. I understand the GM flows better is all but otherwise the same.

I pulled the fender, and you can see the way this setup is done. Now honestly its not a bad setup, just not done well. I have parts coming to clean this up. You can also see the oil line comes in the side, drain is opposite. Turbo now is dumping oil out the exhaust but I got another GM4 for under $100. Thought about the GM8, but rebuilt is $300. Not a terrible price really but I only need 8psi or I need to stud the motor.

Interesting, JR
BTW, I ran dual shocks on my old square body, rough country gassers, I think and liked the ride it gave me. Gonna add a second set of shocks or just go straight to the 3" King's? ;-)

Think I will stay with singles, but with Bilstien reservoirs. Going to let it settle first and get the bumper on.

Got an LED light bar for the grill. I have new LED headlights coming too, housings with seperate LED bulbs, not the all in one that seem to be hit and miss.

First I trimmed the grill for the bar.

JR · « **Reply #255 on:** September 01, 2021, 12:06:38 AM »

Capped the cut off ends. Found the grill had vertical pieces that required just a hole and a spacer for the bar to fit.

So longer bolts and spacers on the lathe.

JR · « **Reply #256 on:** September 01, 2021, 12:08:06 AM »

Test fit before smoothing it out, then a nice coat of semi-gloss black. The curve matched the grill nice!

JR · « **Reply #257 on:** September 01, 2021, 12:09:37 AM »

Works pretty well and even came with a wiring fused/relayed wire harness!

Agreed, nice upgrade

Thx, parts are dribbling in for the turbo remount.

Flyin6 · « **Reply #261 on:** September 01, 2021, 05:11:15 PM »

Cyclops looking thing
Not sure if that is going to grow on me or not
I'll give it some time

JR · « **Reply #262 on:** September 12, 2021, 03:59:34 PM »

Just got a box of headlights for the beast. Glass 4x6 headlights that take a drop in bulb which I have LEDs for. Think between these and the bar, forward illumination should be great!

Now for more time, short until the bobcat is at the ranch and the scraper mod.

Got little things coming along. Was going to rebuild the stock turbo as it was dumping oil out the exhaust.

Ended up getting a GM8 turbo to rebuild. The 8 flows better inside and does not have the flattened exhaust turn down. Forums say if you can, swap and its a direct bolt on. You can see the housing is a little diff as well as the non flattened turn down. Intake bell is also a smooth run into the impeller. Got an aftermarket billet wheel for it to. Will keep boost to under 10psi, maybe closer to 8, stock was just 4.

Yep, it will never be a duramax, but it still ran good. Who knows, studs and more PSI?

Flyin6 · « **Reply #264 on:** October 06, 2021, 01:15:32 PM »

Fred, Imagine if you could push that up to 30psi!

I wonder if building one of those with lower compression would permit some much higher boost numbers?

That motor was a champion of gas mileage. Boosting it higher would improve even more

JR · « **Reply #265 on:** October 06, 2021, 06:47:50 PM »

Not unless I stud the heads. 6.2 did not have a turbo stock so higher comp than the 6.5 and anything above 10psi tends to lift the heads up.

Forgot, its a 6.2

Goes without saying, score yourself a 6.5 and build it over the years and someday toss that in as a duramax killer! (Ya, I know, it's a stretch...)

JR · « **Reply #267 on:** October 07, 2021, 11:14:50 AM »

Oh, I have eyed a 6.5 or two. Just not in the cards for a swap right now.

I have always been interested in one. Would make a killer cruiser

JR · « **Reply #269 on:** October 07, 2021, 01:52:57 PM »

Honest, it runs very well with the hacked turbo.

JR · « **Reply #270 on:** February 17, 2023, 12:03:53 PM »

Well, back to toying this thing after gettng side tracked working on the property, buying a Tahoe and life.

Decided to stick with the GM 4L80 vs the dodge tranny I have for the 6BT. So that is whats in the burb now, but will build to 4L85 specs (good to 1000lb tq). Yes it uses a stand alone TCM, but they are simple and a dime a dozen. Plus parts are easier to get for it. Adapters are not the cheapest, going for around $500 used to just under $1000 new. But simplicity will rule here in the long run.

Also dumped the H2 wheels and dually setup. Got a killer deal on SRW hubs from non other than Randys, and Tate set me up with bearings too. Selling the dually hubs will almost offset the purchace!

I picked up a GM NP205 and 203 last week up near Susanville Ca for $350 for a doubler setup. After reasearch and ideas from Shawn, I may go with a ORD magnum underdrive or similar unit. Even enough a bit pricy it washes out buy the time I sell the dodge tranny and 205 t case, np203 (was $50) I can always run the 205 in the interm which will still work fine.

Flyin6 · « **Reply #271 on:** February 17, 2023, 12:17:56 PM »

That's interesting JR. So the doubler...Allow you to go super low, or add another OD, or both???

JR · « **Reply #272 on:** February 18, 2023, 04:24:00 PM »

That ORD doubler gives you the same od as stock, but you get a 5.1 low, which is crazy low. I am not a real rack crawler per say, but the options are great. Still get a .75 OD with the 4L80/85, so 4.10 gearing it has with 35 tires is perfect.

Need to take to storage as the boys 4Runner needs the room right now. No winch on trailer or Sub, so making one that will work as a base for the bumper build.

I need more projects!

Used CAD and made the frame plates from 3/8. I had a winch plate, so pretty easy. Using the trusty 12k HF winch I got a few years back.

JR · « **Reply #275 on:** June 21, 2023, 02:49:34 PM »

It hangs 7 inches below the upper frame rail. I bent the engage handle flate thinking there would be an issue, no.

Mount is solid and made so adding a support along the top will be simple to strengthen the area up as it will also serve for a front bumper build.

Very little aproach lost, wiring first thing tomorrow. Notice the control box is hanging off the back of the winch. Was really simple, just hang off the rear still using factory hanger, flaten and redrill the tabs and your done.

JR · « **Reply #276 on:** June 21, 2023, 02:53:34 PM »

Worked great, solid. Got it to the local yard and tarped as it is summer!

JR · « **Reply #277 on:** June 23, 2023, 03:44:44 PM »

Picked up a later 4L80e 4x4 core for a rebuild today. Finding the 91-97 are the better and has better cooling and internals that my current 80 does not. Upgrading is easy to an 4L85. Got it for a killer price with a TC, but know it will need upgrading to a low stall. Was told it was from a 2004 that lost 2nd.

Dropped at the yard until runner is going.

Think I got the last major part for this, not that I'm in a hurry right now.

Got a Ron Bonny front engine mount/crossover. Solid weld in unit that allows the pan to be dropped without pulling the engine if need be. Popped up on FB in Reno, got for about 1/2 retail.

Flyin6 · « **Reply #279 on:** January 16, 2024, 11:46:41 AM »

...And JR where is this thing presently? I'm going after all these old cool builds that people have gone soft about posting up. Let's tighten up the shot group here!

;-)

JR · « **Reply #280 on:** January 16, 2024, 12:12:49 PM »

I have been picking up parts, engine crossmember with mount, 4L80 for a rebuild and adapter to for it all in hand.

Looking at big brakes for the Dana 60, undecided.

He is sitting on my trailer right now at the storage yard. With the exc and sons Sonoma room was not there for now.
