78 K30 4BD2T Frame Off Build
Back at long last with an update, progress has been at a standstill the last couple weeks since my welder has been living at work for a project there. Finally picked it back up today and got the engine mounts done Made the main mount tabs by just tacking a piece of 1/4" flatbar to the table...- Overthedge21

Currently deciding between which way to do it now. I can either toss the plates I have and make new ones out of angle iron to allow me to run the plate at a shallower angle, or keep these and stand it up steeper and then just bend it midway down to match the isolator angle and make supports...- Overthedge21

Decided I didn't like the mounts I was building, was gonna hang everything too low and was way overcomplicated Cut the nut sections off the brackets I was building Reinstalled the factory engine mount brackets Isolators fitted up to the brackets. With this I should be able to just run a 1/4"...- Overthedge21

Not a ton, they only make around 240 lbft stock, although I'll probably end up turning the fuel up and maybe upgrading the turbo down the road. So probably top pot around mid 300s- Overthedge21

No sir different engine, the 4bd is basically just an Isuzu 4bt Cummins. It's a 3.9 with almost the same dimensions and 135 gross rated HP. They just run smoother and a little quieter than the Cummins. Oil pan is stock as far as I know, I'm gonna have to modify it myself for sump clearance on...- Overthedge21

Pattern ended up being right on, they line up and bolt to the block like factory. Puts the mounts a touch lower than I'd like but not excessively, and redesigning them to bring the mount surface up higher would make the bolts hard to acess. It got dark while these were cooling, spent that time...- Overthedge21

Now that brings us to today, where I finally got going on building engine mounts. I decided to use the through bolted rubber isolators from speedway motors. I was planning to use the original engine side mount brackets but matching the 45 on the frame side was gonna be a pain and very tight, so...- Overthedge21

Can't find the pictures of me setting the cab so we're just gonna jump-cut to the relative present, the only part that really matters here got the engine and trans bolted together, it's an Isuzu 4BD2T with an NV4500. Custom adapter bellhousing from a man who's no longer in business, but there's...- Overthedge21

Cleaned up and painted the new frame after removing all the old junk I wouldn't need off it Set the new suspension under it, new fuel tank, and got a hell of a deal on some 8x6.5 19.5s Had to cut the back couple inches off the frame because of how the wrecker body sits. Made a little...- Overthedge21

So this was the truck when I got it. Run of the mill best down wrecker. Drove a couple hours one way under the promise that it was solid. Got there to find out the frame was smoked. Whatever, ended up getting it for a fraction of the asking price because of that. Found a frame locally in...- Overthedge21

Been a long time since I've been on here, and I've built several trucks but never bothered to post any of them. This one though I figure I'll actually run a thread on, mainly because there's not a lot of in depth info on this swap. I did a lot of searching before starting it and found that...- Overthedge21

6.5 mechanical hackjob won't run smoothly
No sir that is my fuel tank for right now. All the intake does on these is route air from the filter to the heads. Nothing more. All I had to do was plug up a few ports for oil pressure sensors and whatnot. My oiling system is completely contained, I have the radiator standing behind the engine...- Overthedge21

I had a reason, I believe the db wouldn't fit where the ds was but It was a while ago so I can't remember for certain. Or it may have been something else- Overthedge21

Haha ok a diesel you don't need any of that, the fuel gets sprayed right into the cylinder as opposed to going through the intake so you don't need it for a diesel, and the exhausts don't do a ton for test runs either. Theres oil in it don't worry, again there's no open areas like a gas engine...- Overthedge21

I take that as a partial compliment, I go by the saying "you can't do it wrong if nobody knows what youre doing"- Overthedge21
