Builds Here we go (FJ-40 getting a 3B/Turbo/H55f)...

[DanS HJ-45]

With the help of Alia176 (thanks bro!) we sorted most of the electric problems down (the short, the EDIC issue, the starter issue...) and I also figured out the fuel problems. Turns out the rubber fuel line had a kink it in which caused it to starve itself of fuel after 15-20 minutes.

With that sorted, it has been out on the public road system! No more than 30mph yes, just around the neighborhood (down to the house and back) but....

Getting tired of the videos yet? This time Mom got to drive, so I could film it and get the sound recorded. I have to agree with Ali, this one just might need a muffler, because the turbo whine is AWESOMELY LOUD. Which is, of course, awesome. We'll see how it does with a straight flow muffler and more than 2 feet of exhaust pipe.



Tomorrow to finish up some rough ends, and Dad will actually get a ride in his truck finally. Monday the plan is to get exhaust made, get it aligned, and get it inspected and titled as a diesel. Been a long time coming, but man is it awesome.

Ah sweet! That sounds terrific! Good job man.

super cool video. That turbo whine is great

Lame iphone picture, but here it is in the driveway next to Mom's Power Wagon...


It stopped raining long enough for me to take it out to the Gas station (3-4 miles down the highway). It was kind of cold driving with no doors and no top just after the rain, that's for sure.


The good: it drives BEAUTIFULLY. Not even a shimmy in the wheel, tracks perfectly straight (it was good with the stock PS, but the 60 series PS is WAY better). Drives straighter than my '91 IFS truck.

The bad: it seems underpowered to me. I don't know if I don't have the timing just right (I don't have the IP inspection pipe, so I just realigned the marks), or if the junkyard turbo doesn't boost well, or if there's something else. Doesn't feel like any brakes are dragging, and it feels "normal" at low speeds (25-30mph) but seems to bog down much above that. One of the last electrical issues is the gauge pod has intermittent power, so I'm not sure just what boost it's making or the EGTs exactly.

Either way....

Dan, Are you seeing nay black smoke? It could just be the amount of fuel. I'd turn it up a bit, (but not too much until you are getting good EGT info) and see if that helps a little...

When are you back in town? I have some news on my rig and would love to pick your brain on your resto over a beer...

Not a single bit of black smoke, so I'll give that a shot tomorrow too (and I'll get the pyro/boost gauge working, by hook or by crook). That said, the turbo was installed a long time ago in Australia, so I was assuming that they turned up the fuel, so I'm somewhat hesitant to turn that up too quickly.

When are you back in town? I have some news on my rig and would love to pick your brain on your resto over a beer...

Well, if all goes according to plan I'll be driving the 40 up on Tuesday. If not, I'll fly home on Tuesday. I have to work on Thursday around noon, so we could possibly do an early lunch. If not, I'll be back Sunday the 31st at 7PM or so. And I *should* be at the RS meeting...

Dan

 

[BreckenridgeCruiser]

RS Meeting? What is that? Just kidding. Lacrosse season just let my Wednesdays go so I may be able to actually show up!

Give me a call either way I can't wait to see the truck!

You shouldn't see any black smoke with a Turboed 3B, but you should see a little bit if you give it fuel when it is still not fully warmed up... If you don't see any at start-up or early acceleration, then you are probably pretty safe on upping the fuel a little.

me, i would get the pyro working before playing with the fuel ...
that being said, beauty truck
and
a cool mom if she drives the beast. LOVE the Power Wagon

 

[DanS HJ-45]

OK, so I got the extra gauges (Pyro, Boost, Water Temp) working.... sort of.

The pyro works, as long as the other two are not on at all. Even if powered by completely separate circuits, the instant the Boost or Water Temp gauges are powered up the pyro stops working. Very, very perplexing at the moment. I'm tempted to hook up the pyro itself to a battery and drive the truck around just to see what it says, but really I need to figure out what the blast is up with that.

But, the Boost and Water Temp gauges are working well now (found a loose connection). Wierd thing is, I'm not sure if I can trust the boost gauge. With the Saab 900T turbo on there, it will not boost more than 3psi, no matter what. If I unhook the wastegate, it says it might be up to 3.5psi, but still not much. Not sure how I can test the boost gauge for accuracy, because even if I take the hose and blow into it as hard as I can it barely reads 3/4psi. I'm thinking of turning the air on the shop compressor down to 10psi or so and putting that to the boost gauge, to see what it says...

With the Safari turbo on there before the truck definitely boosted more than that, so at least at one time it indicated higher boost levels, and I didn't do any more than unplug the wiring harness to remove it, and then put it back in after paint.

More time to think.... I'm going to run out and get exhaust studs so that I can put the rebuilt Safari turbo back on there, just to see what it does.

Just an aside, the truck is generally great around the neighborhood, at slow-ish speeds, but the engine does seem to be able to bog down easier than other diesels I've driven. Could that point to an issue?

Dan

 

[DanS HJ-45]

So, swapped turbos. Big difference, but still not where it should be.

Different sound too. This time it will boost to 8psi though. Because it's still sluggish starting from a dead stop, I'm leaning towards the timing being off, since I didn't change the fuel setting, the injectors were just rebuilt, and I didn't monkey with the valves or anything.



But, I'm off to town to borrow a tool to finish up the soft top bows.

Dan

 

[crushers]

i doubt you will have rocket acceleration from a dead stop. second should pull better than first and third will be an eye opener

 

[DanS HJ-45]

It's not that it's rocket acceleration, it's that it needs quite a bit of gas to keep from stalling if there is the slightest incline. More so than the gas vehicles we've got.

Here's the timing marks before I pulled the IP...


They are perfectly lined up now (not sure how, pretty sure I set them up just like this when I put it back). The bigger question is, how on earth do you rotate the IP with everything hooked up to it in the truck? It doesn't want to budge, and yes I've got all 4 bolts loose (the three at the flange, and the rear hinge-ey bolt)

Dan

 

[crushers]

loosen the injector lines ...
i would rotate the pump (top) towards the motor 1/4" (at the marks) and give that a try.

there is no way a 3B shoudl stall on a slight incline, they are tractor engines and are actually hard to stall in first. interesting and confusing.

Exactly. To add to confusion, on a mostly level highway, where my faux-lux can drive in 5th gear and never get the EGT to even tough 900 dgrees at 50mph, this truck is BARELY able to go up the hills at 35, in third gear (and even then it's not happy).

I haven't gotten it into 5th gear at all, even 4th is almost useless with the power level of the engine right now.

I'll take the lines off and give it a twist, see how that goes...

Dan-

Is the pyro working yet? If so, that might tell us something?
Maybe a silly question but, we're sure there are no blockages from incoming air and/or exhaust?
I really want to know where that fuels set at. The pyro wil help us there.
Wicked spool from the first turbo, perplexing it will only boost to 3psi with that sound though.
Throttle body linkage is not being obstructed in any way?
Any intake leaks and/or all connections regarding the piping have been double checked?
Just throwing these out Dan ad we all know and appreciate your efforts on this rig. Good news is, this will get figured out so keep investigating. Got me puzzled though.

 

[crushers]

it seems i might be doing a drive from Saskatoon to SanDiego in late sept/early oct and i would love to stop by and take a look in person at this work of art.

sounds to me like a fueling problem, stick a feeder pump near the fuel cell and see if there is any change. post up some pics of the air intake system again. post up pics of the exhaust again. you have a restriction somewhere. That engine should be good for at least 85 mph and very decent acceleration.

cheers

Crushers, if you're planning on heading through the north bay area (north of San Francisco) of California on your way to San Diego, and need a pit stop, drop me a PM.


Dan, your dad's truck's looking great! I'm totally jealous!

 

[crushers]

i will post up on the troopy thread when i am leaving and what general direction i will be traveling. i hope to meet up with a number of fellow cruiserheads on the trip. a detour is acceptable. it would be a joy to meet up CC

sorry to hijack the thread Dan.
cheers

Dan-

Is the pyro working yet? If so, that might tell us something?

Only if the boost and water temp are both off. I'll give it a try with just the pyro and see what I see...

Maybe a silly question but, we're sure there are no blockages from incoming air and/or exhaust?

Positive on the exhaust. The exhaust consists of a 2 foot dump pipe, an I can see straight through it. The intake I'll double check, but it's a big, beefy and mostly metal intake.

I really want to know where that fuels set at. The pyro wil help us there.
Wicked spool from the first turbo, perplexing it will only boost to 3psi with that sound though.
Throttle body linkage is not being obstructed in any way?
Any intake leaks and/or all connections regarding the piping have been double checked?

I think so. I'm wondering what the best way to look for intake leaks would be. I'm taking a bottle of water with soap in it to spray along the intake to see if it's leaking somewhere (I don't hear anything that sounds like a leak)

Just throwing these out Dan ad we all know and appreciate your efforts on this rig. Good news is, this will get figured out so keep investigating. Got me puzzled though.

I appreciate it absolutely. This has me a bit stumped as you can see. I figure the good news is that:

• The injectors are rebuilt
• The engine ran before, and other than cleaning I didn't mess with it at all.
• The IP was fine before, and other than the diaphragm I didn't mess with it internally.
• The truck drives decently to test it.

it seems i might be doing a drive from Saskatoon to SanDiego in late sept/early oct and i would love to stop by and take a look in person at this work of art.

That can probably be arranged. Keep us posted on the dates and itinerary (the truck will be either in Colorado or New Mexico, depending on how things go).

Just picked up a 12V fuel pump. I agree it seems like fuel to me, but that's based on my gut instinct. Earlier it had a rubber fuel line that was pinching, and starving the engine of fuel eventually, once I sorted that problem out, it not only didn't starve of fuel, it also had more power. Kind of makes me think something fuel related is going on here too...

Dan

 

[BreckenridgeCruiser]

Dan,

On the gauges, do some of them ground through the mounting? I know that EGT gauges work based on microvoltage so maybe pushing 12v through the housing for a ground may be causing the interference...

Just an idea.
