Builds FJ 45 Extended Cab Custom Vehicle Build Finally Begins (2 Viewers)

[D'Animal]

Fuel fill neck stand pipe is next. I started on the front tank since it is the primary tank.

Mockup was done with PVC pipe. I cut holes in the bed floor for the fill pipes. I used 2" pipe for the down pipes.

If you ever want to use the Big Truck diesel pumps, you have to have a Burp pipe.

You do not NEED one if you use the regular pumps, but it sure makes it nice.

The Burp pipe installed.

In the bottom picture you can see it installed deep enough that you can still fit the diesel filler hose at the fuel station in the fuel fill pipe.

It is really hard to see but it is angle cut and bent in such a way that fuel will not flow into it while fueling.

 

[D'Animal]

Installed and plumbed.


Time for the rear tank.

 

[D'Animal]

Slow but steady progress.


Most of the bodywork on the driverside is completed. The black areas are SEM High Build Primer Surfacer. Next step is wait for warm weather to give it a skim coat of EverCoat Z-Grip and finish all the little things.

WOW that is a thing of beauty.... how many truck are in that thing though ... I thought I had alot

 

[ToyotaDon]

Glad to see you back at it!

I was almost considering something drastic, like going out there and helping you.

 

[GLTHFJ60]

Love that rig.

What's the plan on the regear?

 

[D'Animal]

I'm against the rev limiter/governor on the engine when driving 60mph with 4:88's. Fuel economy is bad.

I have a NV 4500 and a 4:1Orion so Im looking at 3:73's or maybe 4:11's.

What's the plan on the regear?

I have not really found a gear selection chart/worksheet that has my powertrain combination so I'm a bit limited on being able to research it for optimum performance.

Hey Dan,

Great build. Really great build. Here is the gear claculator you are looking for. Use the drop down "enter your own number" selection on the page and it has every combo you can imagine.

What kind of RPM is it spinning @ 60? I'm thinking it'd be down around 1700 which I would think would be just low of the "happy spot" of that motor.

If you need them, I have a good set of 4.10s out of an 80. Only 1 set but there yours if you want them.

That spreadsheet is cool, but since you already know what you're spinning at 60 mph and you're not changing anything in the tranny/trans/tire combo, you can calculate pretty easy what a gear change will do for you.

For 3.73:
Take your RPM's at 60 mph, multiply by 3.73 and divide by your current ratio (4.88). The answer is what your RPM's would be at 60 mph with 3.73 gears.

Is that in 4th? Overdrive looks alright with 4.88s from the number crunching. I can't remember if you put in the 366 spring that allows up to 3200rpm? Those using the 4500 have commented that helps drivability due to the gear spacing on those trannies. I've put one in even though I'm running an auto and noticed it gives me a nicer rpm range so I could imagine it being more helpful in a manual where rpm range is a little more important. Plus the springs are cheap!

Since you've got quite a bit of tire on there and you take this offroad I wouldn't suggest going to 3.73s. I don't doubt the engine will pull it but I'd think 4.11s would be a better compromise. It might be a little bit of extra work but 4.11s and 3.73s are everywhere so you could try out both and see what you like better.

Would they fit in 60 series housings?

The rear will, but the front won't, If you can get a pair of rears your all good I believe.

80 series front has a high pinion, pretty good going forward but known to let go trying to reverse out of trouble, smaller pumpkin though has advantages too.

It would be nice to find 2 80 sereis rears with the lockers in them.....

For a DD type weekend wheeler, for sure. For a purpose built hardcore rig- not so much.

Better off with a pair of ARBs for selectable lockers. The 80 series elocker rear end is stout- apparently is has some truly enormous carrier bearings, however the elocker has it's problems.

They are slow to engage/disengage compared to an ARB. The parts to repair the actuator if broken are extremely expensive.

The worst part is if you break an axle shaft with the locker engaged, and the splines on the part of the axle shaft inside the dog clutch twist, your third member can be junk as there is not a way to get the stub of the axle shaft out of the carrier. (it twists when it breaks.

Ya'll might already be aware of these shortcomings, but in case you weren't, I'd thought I'd point them out. Don't want anyone spending the coin and time to get a pair and then find out for themselves that the elockers aren't great for some applications.

Thanks for the input. I did not know 80 series thirds would even fit in a 60 housing. I thought they were interchangable with the mini trucks.

I think the front is interchangeable with mini trucks. But never quite sure what you mean by min truck (Hi Lux)?
