FJ to BJ mutation?

[Otterav]

Sorry for a hijack....
Aligning the engine is not too bad. I suggest you have an engine hoist, floor jack, two jack stands and some large C clamps. I got the engine close to where I wanted it with the hoist and floor jack, then clamped the frame mounts into position. It took some readjusting here and there, but once you have one or two mounts clamped where you want them, you can ajust the angles easily. I even moved mine backwards about two inches from where I had it clamped orginally.
Once you have things where you want them, or have fabricated what you need. Take a sharpie and outline the holes and mounts. I wound up pulling the motor twice during this process.

Hey,
I agree, sounds like you had the original mounts. it sounds like Durock has only an engine and nothing else. After measuring my mount locations, I installed the mounts, then the engine/trans, which went in way too easy! My original statement was, that the engine/trans mounts are multi angled fairly complex pieces and purchasing them already made was the most economical in terms of time and money.I will make/fab some mounts, for anyone who wants them , price starts at $1000.00, more installed!. I can work on aircraft all day/week long at $65.00 cash per hour. And as I said, my swap was complete from driving in to driving out and around in less than 5 weeks with nominal fabrication required! There are many varied ways to skin a cat, I just choose the shortest, most direct path to a cat skin coat! What I wanna see is a cruiser with a 3116 Caterpillar under the hood, now thats fabricatin'!

hey,
I was out back fabbing the turbo mounting stuff, and plumbing.
Here a few snappers of the new intake tube from the turbo to the intake:

Tomorrow hopefully the oil plumbing(pressure) will be finished after I pick up a fitting, more flicks when progress continues.

Woah ! Thanks A lot for the info Otterav !

The way rutbeer did his swap is what I had in mind. only I might have to fab some mounts ... that is, if I cant find any in a junkyard.
Thanks again for the pics and advice !

 

[Otterav]

Well,
I was working on the turbo stuff today, got the plumbing done and bolted the critter back together. With the stuff on, I couldn't resist, I fired it up! Just wanted to hear some turbo noises, who hoo ,whooot whoot. The turbo make positive pressure at idle, I could feel air leaking past the tack welded joints. A little rpms and the air was whooshing out of the unwelded joints with a fury. Tomorrow I will weld the intake tube up, add some bracing, weld a bung or two for the boost gauge.

Well,
I have been driving around with a 8" stack, a K&N aircleaner mounted to the turbo with a couple of adapters. Fabbed the exhaust today no muffler planned, will decide after driving a bit. Will post ficks tomorrow.

Welll,
I finished the exhaust pipe, ran it outside the frame(stock), tucked it in at the front spring hanger, over the axle and out the side, here are some flicks:

Been driving, I think my previous review was too conservative, the difference is otherworldy, better than I originally thought. I have been running some of the roads around here that I had driven pre-turbo, and all I can say is wow, a whole different truck! Will post mileage figgers when I have a new set!

Hello,
I am in the process of finishing up this conversion, the final details are the, airbox and I think another exhaust hanger. Here are some flicks:
I thought I would advertize the powerplant:

I added the sticker when I started running bio-diesel:

Hello,
I am here to say that I am considering my mutation of the FJ into the FJ/BJ mutant is complete. Here are the final flicks of the airbox install. I ended up having to do a little metalwork to notch the airbox so it would clear the waste gate actuator. I then found out that the intake snorkel wouldnt fit under the hood facing forward.
Next issue, I had to section the intake snorkel 90degrees down to line up on the turbo centerline axis. More metal work, 'cept the ole tig machine wasn't gonna be able to fill the gaps. I broke out the really old oxy-acetylene torch and the brazing rod. This worked like a charm, filling the gaps nicely. Here are some flicks:

I will replace the orange tube with a silicone 90 degree elbow that I just ordered.
All in all, my favorite mod yet!

[rutbeer]

That's EXACTLY what I want to do to my intake hose.

 

[Otterav]

Well,
I decided to jack with the fuel, I unscrewed the DHAC one full turn, difference was very noticeable. I first turned it one full turn in the wrong direction, kinda like some one let all the air out of the tires and hooked a 2000lb trailer when I wasn't looking. turned it back to the original setting then gave it a full turn out, WOW kinda like a top fueler now, my test hill will be climbed in 4th and egts showing 1000 egt at the turbo exit, I think that this will be the limit for now.

Hello,
Went wheeling to Hollister Hills SVRA for a few lite trails and crawling. Drive down was easy, hills that I used to have to down shift were dealt with by stepping on the loud pedal. Once we were off road the 3B and turbo behaved perfectly, power was easy to modulate, I did not have to "get a run at it" types of driving methods. Traction was sketchy dry dirt sprinkled with talcum powder grade dust. I tremendously impressed with the manners of the 3B/turbo combo, initial power was "soft" from O-1/8th throttle, above 1/8th throttle power was linear and very easy to control. The truck has the original radiator and outside air temp was 90+, the oil pressure stayed up and the coolant remained lower than street driving. I would wholeheartedly recommend the CT26 turbo/13BT manifold combo with 2 1/2" exhaust(no muffler), as an excellent combo. I was gonna buy a Garrett GT2544R to replace the CT26, I was worried about turbo lag, no longer planning on swapping the CT out. With CT26s going for about $75-100 clams and an eBay rebuild kit for $80.00, makes for a very affordable turbo for the 3B. Oh yes I previously said I wasn't gonna up the fuel any more, I added another turn out on the fuel. It seems that the extra fuel spins the turbo faster off idle and pushes more air into the manifold, with my driving style my EGTs are actually lower for a given speed and road condition, go figger.
Here is a flick of the cruiser in a powder bowl:

P.S. The left rear and the right front were off the ground, if I leaned one way or another and the tires would touch!

Hi All:

"Otterav," thanks for sharing with us your FJ to BJ conversion!

What an awesome project!

Hope the rig works out as you plan!

Alan,
The swap was even better than I thought it would be! The turbo was pure icing and candles!! I was driving up one of our hills today, when I got to the top it was like a spark plug had fouled, s*** broke the new toy already, not so fast. it seems that when I started running bio-diesel my already unreliable fuel level sender finally crapped out. I coasted down the hill and filled up on dino squeezins, drove back to the house, bled the injector lines, problem solved! Low fuel caused a slug of air into the injector lines, causing the fouled spark plug sounds/running. Back to runnin' like a top.

Hello,
I thought a followup would be in order. It seems since I tossed a diesel into the 'ole cruiser, I was needin' a diesel generator to round out the collection, got one on e-Bay 3KW x-military diesel generator. Cool deal, pull start with the electric option installed, sucker even has glow a plug. You might ask, so what? It seems that the generator was in Alturas, CA, 'bout 450 road miles from home, thought "I will just crank up the cruiser and check the mileage. left home at 10:00PM, headed up Highway 5 at 55-60MPH, got to Redding and turned east onto highway 299 and drove for about 140 miles. Got to Alturas at 7:00 made the deal for 2 generators and took off down highway 395 towards Reno. Got to Reno and headed west on highway 80 back to the Santa Cruz area around 8:00 PM. Total mileage 914 miles as the GPS goes, time elapsed around 22 hours, time moving 18:45, average speed was 50MPH. Gotta love the GPS! MPG was around 23-24. I will have the final numbers tomorrow(out in the cruiser), as well as a pic or 2.
Here is a cruiser hiding behind a bush:

Some more flicks of some stuff:
I fabricated a hand throttle, here is the engine bracket:

Here is a shot of the 3KW diesel generator:

Great work man, and good to hear on the performance!

Eric,
I can't wait for the next camping trip! Are you getting any oil splash from the valve cover? Did you plumb an oil separator between the valve cover breather and the air inlet pipe for the turbo- like we discussed for my 2h? background- I was getting a fair bit of oil collecting at the intake manifold even with a new cartridge. After inquiring with turboglide, I was told that it is normal and that it is the oil splashing off of the rockers and geting sucked through the turbo and into the intake. Obviously the valve cover is vented into the air intake pipe for the turbo. Anyway, we discussed using an inline aviation air/oil seperator to drain the oil back into the pan and keep my intake clean.

Best,
David

David,
My 3B does not have a valvecover vent on it. The only vent on the engine is on the tappet cover on the right side of the engine. I ran the tappet cover vent to the air/oil separator. If your valve cover has a vent and you have a tappet crankcase vent, I would run these to a "Y" and then the combined outflow to the separator. My turbo intake is dry and clean, I would be leery of running air/oil mist into the intake of a diesel, you are effectively running additional fuel into the engine. My separator works like a charm, the original cruiser had the entire bottom of the cruiser coated with blowby oil mist. Before I installed the separator my cruiser was getting a good misting from the tappet cover vent. Ah yes the camping trip, was awesome gonna try for surf and turf this year! You gonna be stateside for that? At any rate enjoy your travels and remember I am looking for a CT-12 turbo, there are tons of them lying around over there!!! Keep us posted and enjoy!

Eric,
If I recall correctly there are two versions of the ct12/ct12b. I believe the ct12 was used on the 2.0 liter engines and the ct12B was used on the 3.0 liter engines like the cruisers and the 4runners. I'm assuming the ct12B is the one your after.?.? check out this link and let me know which casting number you're looking for:

http://www.melett.com/pdfs/Toyota/Toyota Applications.pdf

I'll see what I can find.

 

[Otterav]

David,
WhooHoo, I would be interested in a CT-12, CT-12B, and/or a CT-20,
Hell, I would take one each of all the above, I would do a comparison test for the readers of this thread. First choice of castings would be a turbo off of a 4 cyl followed by 6 cyl models.
