Another 5.3 swap.

I would wager that is made of a glass filled nylon, with works very well with many adhesives. Cyanoacrylate (super glue) is actually one of the better glues for nylon. It can achieve bond strengths higher than the material strength. Loctite make a huge variety of industrial glues. One will probably do what you need.

Nice work with the swap, hoping I can do something similar one of these days.

I couldn't help but notice your seats in the bottom of this picture. What are they? They are not original seats that you had redone are they?

Thanks and the seats are just those cheap racing style seats you can get at O'Reily or Autozone. I had to do some mods. to make them work on the original bases, but it wasn't too bad. They are pretty comfortable once you are in them, but they really suck for getting in and out. I am probably going to try to find something different one of these days.

Nice job Jeff.

I had to do the same thing with my DBW pedal. I cut it off and welded a much shorter piece on to it. These pics don't show the foot pad yet. Just the arm. And the springs are loose in the second pic.
These DBW pedals are sweet. I am mounting the ECM, DBW module, relays and fuse panel inside the cab under the dash to help keep the engine bay clean.

I enjoy your build.

VERY nice. Yours is sure prettier than mine.

It might have already been asked but what is that 4wd shifter out of? Also, what are you getting for mileage on the interstate? Did you go hydroboost? The Jeep looks great, I think I'm going to go the same route on my next GW

Thanks, the shifter is out of an 89 Blazer and I don't have hydroboost. I haven't actually had a chance to get an interstate milage reading yet, but I am planning to take it on the interstate over Xmas. I will try to get a reading and I'll post it.

Yup. That is where it is located in the original Yukon the engine came from. In fact, in the Yukon, it is mounted in a plastic cover(far from water proof) just behind the radiator, almost sitting on the frame. It is actually in a much higher and safer spot now. From what I'm told, these are very tough and waterproof. I do plan to fabricate some sort of splash guard for it anyway, before I do any real serious mud play.

91 and up xjs have the ecm on the side of the drivers inner fender and I've never heard of them having any problems and haven't heard of anyone moving it. I have a 87 so it's inside where I like it.
What is the smaller computer on the firewall? I thought it was the ecm and was diggin it. Also what does the the throttle body warmer do?

The smaller box is the control box for the electronic gas pedal. The throttle body warmer is to keep the throttle body from freezing up in very cold weather. It is fed by a small coolant line from the radiator.

It can run to the radiator or you can drill and tap the water pump housing. Like this:







These Gen III GM engines are a thing of beauty and efficiency. They run so smoothly and are true works of art. My favorite part is the individual coil packs on the valve covers and how clean the spark plug wires are. No more snakes running everywhere. And no giant distributor to deal with.



The only strange thing to me is the extremely small oil filter. Looks like something off a Honda Civic.

That is another great way to run that hose and I completely agree with you on the filter. lol. I do love the engines though and with some of the mileage #'s on them, I have a hard time worrying too much about the small filters. I have considered trying a filter from a 2000 5.3. That's what's in our Yukon and the filter is taller. The block is the same, so it seems like it should work. I just don't know if they had some reason for the smaller filter and haven't really looked into it.

This is the second 5.3 swap on here, is there a website where you are posting more pictures or maybe doing a more detailed write up? I was going to go 6.6L Duramax but the money involved is more than I want to spend. The 5.3L Vortec seems a more reasonable replacement and a little more straight forward.

I'm sure they wouldn't have made it for nothing but wouldn't the heat from the engine be plenty to keep the TB warm?

Heres a picture from the torchmate buggy on pirate which looks like it has a shorter oem aluminum pan thats even with the dinky oil filter. Maybe the factory pan setup was why? I believe they got that out of a newer gto.

[BigJ200]

The small filter must be fine. It looks dinky, but I am sure they wouldn't put so much effort into the Gen III motors then slap on a useless filter. It definitely shows how efficient and clean running these engines are though.

Yea they got such tighter tolerences than your v8s running 40w.
