Turbo 3B vs 13-BT

[RufusTheDufus]

Can anyone confirm whether the rods are infact bigger on the 13bt than the 3b because i cant see the guy in the video just picking up a random rod and saying it is out of a 3b when it is not??

The guy in the video didn't say the rod was from a 3B. He said it's from a "normally aspirated" engine. If you watch closely there's a "H" written on that rod in black marker. I wouldn't be surprised if that means the rod is from an H (not 2H) engine.

books are books written by humans for the reason of? edumacation, profit, supply and demand, glory. the internet is popular because? (the same reasons) but not all that is on the net OR IN PRINT is based on real world experience, is it?

Hello,

This is an interesting thread.

Not everything can be found in books (or the Internet,) and usually experience provides a sort of "reality check" for printed or electronic information. Checks and cross references exist for a reason.

An engine can suffer from either a poor design or plain abuse. Any of them or both will in the end kill it. On the other hand, a well-designed engine will allow for modifications and may do things its designers did not foresee, like running on a turbo.

Again, abuse will kill even the best engine.

It is not only the nut behind the wheel, as Wayne likes to say, but also the nut at the drawing board. True, one should not pretend to outsmart the designers, but they may not have foreseen every application or modification in their plans. That is potential; some engines have it and some don't.

Just my two cents, no flames intended.

at the risk of jumping into a dogpile i'll give my thoughts...

I drive a 3B-t powered BJ60. It's been reliable enought to drive on a 12,000km trip to NWT/ AK. It's been taken care of, and has a garrett off an Onan gen. It has 480,000 original k's and has never been apart. It's only been turbo'd from 435,000. So I think a well looked after 3B-t with a decent turbo sys is reliable. Obviously don't buy a 3B with some cobbled contraption strapped to it. Would I like a 13B-T? I'd probably take one over my setup but that's just cause it is a factory turbo and has a decent rep. It's actually a small issue though so- I would say just buy the truck that is in better condition, that's what matters. Don't be scared of a decent 3B-T.

I don't know what all the bashing is about. BJ never said anything about 2L's or 2L-T's so you don't have grounds. IF he had said a 2L-T is better than a 2L with a turbo strapped to it, well then... L's are known to be sketchy propositions...duh

Fuel mileage: 650km/80L for mix driving. About 23mpg. 285/75/16's, 3.7's. on the highway i get closer to 25mpg. I don't know how that compares to 13B-t's but it's good nuff for me

you are right, he never said the 2LT(e) was a good engine but what he DID say was

"Originally Posted by BEE-JAY42
"A 13B-T IS DESIGNED TO RUN ON A FORCED AIR INDUCTION, A 3B IS NOT, IT IS DESIGNED TO RECIEVE AIR AT ATMOSPHERIC PRESSURE, WHICH ONE DO YOU THINK IS BETTER SUITED TO A FORCED AIR INDUCTION SYSTEM?"

which leads to the conclusion that Toyota engineers knew that the 2L would not last so they DESIGNED the 2LT(E) to be turbo'd which ... still didn't last.
so ... in a nut shell just because an engine was designed to be turbo'd does not make it a better engine.

i suppose- at least he never said to stick 46 lbs to your stock 1hd-t

 

[Gold Boy]

one thing about the 3b-t, is it's way less busy under the hood tan the 13bt, so assume it's easer to work on?

crusher has a point , .... it really does not matter between a 3B or a 13BT. engine is engine

any of these engines have strength and weaknesses..

Im sure when I pulled the 13B-T apart on my truck a few months ago the CONROD had 3B stamped on it as we were checking it to see if we could convert it to 14B-T and we did not have the CRANK and the CONRODs as they were different parts.
