Haha, no interest in 3B's really, so haven't noticed, more interested in 1HD's and 1VD's.

 

[crushers]

glad you saw the humor...
me, i am a HZ and PZ boy ... Bs are for the Stateboys.

I never thought this thread would bring out such controversy and strong opinions. Thank God we are not discussing the 2L-TE!
So now we are being called the "stateboys"...oh well we have been called worse...............1978HJ45

 

[bj70_guy]

Some of us West Coasters are mighty fond of our Bs too...

 

[gotoy]

nah, it is just confusing for those that can't think outside the box.
we have been using this designation for a 3B + aftermarket Turbo for years now. catch up grandpa.

Inventions!

 

[gotoy]

now it could be your comprehension, or maybe it is your reading words into my posts but where did i say there was a FACTORY turbo 3B?
i said, a turbo 3B will have more power than the 13BT.

If you would use the correct terminology there would be no confusion! By using 3B-T.....you are just copying toyota factory codes.

There was a time someone used 3l-T for a 2.8 engine added with a CT-20 turbo from a 2LT.

Adding a turbo may have the reverse effect on an engine, if he wrong spec/size is used.

No probs Crushers.

I have a 1HZ-T in my Troopy.

The 1HZ is a little gutless in a Troopy, especially trying to plough through deep/heavy snow (not deep by your standards), so the turbo helps.

Problem is that popular opinion says the turbo will make it go bang eventually, or probably much sooner.

So in looking forward to that, I am interested in probably a 1HD-FT or 1HD-FTE for when that happens, for a little more grunt and apparently a lot more reliability.

Hopefully I get the loan that I took out for the Troopy paid off before then, so I can loan up again for the 1HD-FTE plus installation.

 

[gotoy]

.........and the F is for what? As in -FTE.

 

[crushers]

edit:
shown the error of my ways, thanks Simon

of course, those that want to write "3B with added turbo charger and intercooler and propane injection" each time they describe an engine are free to do so.

but i will carry on using the lettering i do, do try and keep up.

This is like having an argument with your wife.....after it is over with it can be hard to dertermine the winner.

for the inexperienced and those that can't keep up:

Your "experience" seems to have clouded your perception of reality, gramps.

Toyota designation of turbo'd motors do not have a dash (-) between the engine size code and the turbo designation (13BT)(HDT)(12HT).

Ummm, someone forgot to tell Toyota, Crushers!

For example...

...and this one mentions 2L-T, 13B-T, 2H-T, 12H-T...

added turbo to engines normally not having a turbo would read as (-T) (3B-T)(3L-T)(HZ-T)(PZ-T)

That would just confuse people, like you did in this case, as you are using the SAME codes that Toyota uses for their factory turbo engines.

i understand that to some this might be confusing but to the open minded this makes total sense.

Your mind may not be as open as you think?

since there is no "correct terminology" for adding a trubo, intercooler, propane injection designation from the factory, this will have to suffice.

Nope, there is a "correct terminology" for a factory turbo from Toyota, it is the "-T" suffix.

clear as Mud?

Obviously not to you!


Some additional references...
Toyota engine codes@Everything2.com

Toyota's engine codes follow a series of logical naming conventions, which unlike those of some other companies, make it possible to know something about an engine without having anything but the code.

Toyota Engine Codes have two groups of characters, separated by a dash. The first group tells you which series the engine is from (designated by a letter or letters) and which revision version it is.

After the dash comes another string of characters, which designate things like what sort of head the engine is equipped with, whether it is turbocharged or supercharged, what emissions control systems it comes with, etc etc.

Toyota Engine Codes Explained - Toymods Car Club

Toyota engine codes are split into two sections, the bit before the dash, and the bit after it (eg: 2JZ-GTE).

Before the dash.
The letters signify the "family" or "series" of the engine. The numbers signify the revision of that engine within its series, usually an alteration in the bore/stroke.

After the dash.
The letters after the dash indicate the specific features of the engine.
G - Wide angle Twin Cam head, independantly geared camshafts
F - Narrow angle Twin Cam head, common geared camshafts
T - Turbocharged
Z - Supercharged
E - Electronic Fuel Injection system


...and...

1. The first numeric characters specify the engine block's generation
2. The next one or two letters specify the engine family
3. The suffix (separated by a dash) specifies the features of the engine:
B Twin SU-style side-draft carburetors
C California-spec emissions
D Twin Downdraft carburetors
E Electronic Fuel injection
F Economy narrow-angle DOHC
G Performance wide-angle DOHC
H High compression like 9.8:1 (example: 5E-FHE) or High pressure charged (example: 2L-THE)
i Single-point fuel injection
J Unknown meaning (example: 2Y-J Low rpm type?)
L Transverse
P Unknown meaning (example: 3RZ-FP)
R Air injection
S Swirl intake (1980s)
SE Direct injection (1990s)
T Turbocharged
U With Catalytic converter Japan-spec emissions
X Atkinson cycle
Z Supercharged
P LPG fuel
N CNG fuel

That last list of suffixes seems to indicate that there is a factory suffix for LPG (Propane) as well.

[gotoy]

So what turbo are you actually fitting onto the 3B to make it into a 3B(-T)?

Hmm.....(-T).....I am amused with that

 

[crushers]

or, as i was thinking on how to make this work for everyone ...
3B+T ...simple clean and understandable.

so 3B+TIPI would be 3b with turbo/intercooler/propane injection.

 

[Gun Runner 5]

Yo Crushers....For the benefit of us poor "Stateboys" that are not well versed on diesel Cruisers, what the heck does propane injection do for a diesel engine? ..............1978HJ45

 

[crushers]

if PROPERLY installed it is like a second turbo ...
if NOT properly installed it is like a time bomb (but a hell of a lot of fun till it does blow)

 

[lshobie]

I'm with wayne, it's not hard to figure out what he means by the 3B-T, stick around the diesel section or any other cruiser diesel sections and you will see people make their own acronyms to save on typing. My truck is an hzj79 1HZ TH20IR1518274ARBELDualBat3"MBE36/13/R16C4"SUF

Say that ten times fast.

Remember Wayne, I have a 2L-TE so I have enough "time bomb" issues. Thanks for the information. ...............1978HJ45

 

[crushers]

i tried propane injection on a 2LTE and it did squat... i suspect the fuel sensor cut back the fuel. waste of time on those engines.
"e" engines suck.
you are going to love the B when you get it. more power than the 2LTE. better fuel economy. better reliability.
i going to guess that you are pulling the 2LTE and sticking the B into your 78??
