the 1HD-FTE at 4.2L is only 430Nm...
and yet you accomplished 520Nm at 2000 rpm on a 3.8L with just an increase pf turbo pressure to 20 PSI from stock...and a bit of fuel
with nothing else done to the engine...
that is impressive

The 100 series with the 1HD-FTE doesn't have the same squirt off the mark, but with a wider rev range and auto gearbox it can still just beat me to 100km/h.

To get more boost I need a turbo capable of higher pressure ratios. I'm already pushing the T25 off the top right of the compressor map.
I need a bigger exhaust to do that.
Air/water intercooler has been taking up shelf space for almost two years now. Too many projects, too little time.

520Nm is 400ft-lbs. Cummins have 4BT's which did that stock and you can guarantee Isuzu copied all cummins good ideas.

Wow!

I expected more from you, with all that book learnin' and all.

Took me about 4 hours to fab mine

You spend alot of time online!

520Nm is 400ft-lbs. Cummins have 4BT's which did that stock and you can guarantee Isuzu copied all cummins good ideas.

"I know of several Isuzus in delivery trucks that were rebuilt at 500,000km (300,000miles), but I don't know what state they were in then.
One factor to consider is the Isuzus are factory rated lower than the cummins (less torque, spin faster to generate the same power). At the same torque levels I'm afraid my money would be on the cummins too." Remember this quote?


You missed your calling, I am sure Cummins or Isuzu would love to have you on staff, since they missed so much I bet you could set them straight, shoot them your resume!

P.S. when you have your dyno runs on paper post those up with all the other examples of your work. BTW can you give me the number of the blacksmith who made your twin turbo adapter, I have a need for a wrought iron gate for the house and would love to have that look.

Wow!

Eric, go stalk someone else.

Holy smoke man. The guy doesn't have to defend every freakn thing he has done to his truck, or hasn't done. So if I post up manifolds I have made you are going to dis them too?? If I had to defend every thing I haven't done to my truck we would be here all night. Just because crushers retarded personal attack thread is deleted doesn't mean its suppose to start up on another thread.
And in keeping with this thread... my next manifold will have the least volume possible with few bends to achieve the least back pressure, least weight, and the greatest thermal efficiency. This will be after I finish my garage, re-roof my house, renovate 2 spare bedrooms and help my wife have our second child (she will be doing most of the work on that one). I know..I know... Im just lazy...

Gerg,
back off!!

i did not insult his work, i am actually interested in what he has accomplished. if he is pushing 520Nm then that is impressive. the idea he had to rebuild an engine 4 times and had the paitence to do so shows determination.
i can respect that.

Thats the point! Over at 4btswaps(where he suggested I go and check his previously posted work). I did as he suggested, and from 173 threads that he posted there were 4-5 posts that when the photo link addresses were checked, were the only ones linked to his hosting account. For such a prolific poster, who has so many strong opinions, I would expect a larger body of work to support his contentions. This message board is for Toyota enthusiasts who like the marque. If he has said anything complementary about a Toyota vehicle it is eclipsed by all the negative comments about Toyotas. I know that book knowledge is important, as is real world experience. He has implied that I am a liar, Wayne is a whole bunch of other things. When he is questioned about his "theories" he tells the poster he does not know what he is talking about, even when his theories are not supported by other recognized sources. Most every one here who owns a Toyota, likes and owns their vehicle by choice, and when asked will post a picture or link if able. Every one here is of varying experience and skill levels, good on them for making the effort to learn and further their skills, no matter what level they are at, and every post and picture always shows progress and knowledge gained, even if it was from a mistake. Thats learning!
I personally love anything mechanical, Toyota, Ford, Dodge, Landrover(yes rovers too!), rock buggys, crawlers, boggers, and anything with wheels or tracks, skis, floats ect. If he won't post a pic of anything he has done, I can only assume one thing, he is either embarrassed(I doubt), or hasn't done anything, so therefore has nothing to post. I posted a flick of my 1968 M109A3 military truck, manufactured by Willys/Jeep(gasp), and guess what no one said anything negative at all, quite the contrary. So my opinion is, theory is critical, but lab time is also what either supports or refutes that theory. Einstein started the theory but the guys and gals at the Stanford Linear Accelerator(SLAC), and Fermi Labs continue the quest with practical lab experience. Every discipline uses this approach. There are many ways to skin a cat, he refuses to acknowledge that concept. He invited me to go over to 4btswaps and I did, and did not find much to support that he has even worked on his beloved engine(with any success). So the process of elimination would suggest there are 2 possibilities, 1) He is a total wizard expert or 2) He is the Wizard of Oz, hiding behind the internet curtain. Decide for yourself!

P.S. Clutch fork that looks like a spoon:

....... He has implied that I am a liar, Wayne is a whole bunch of other things...........

OK. So I've found this thread now (that obviously led to the one Crusher/Wayne started that has since been chopped by Woody).

Eric - With respect, I think it is just Wayne and you that see Dougal's comments as "personal attacks on each of you".

On the other hand, your comments towards him are seen VERY CLEARLY by most of us a "personal attacks". (OK. I can't speak for others. I should say - I BELIEVE others, like me, see your comments as personal attacks on Dougal.)

It amazes me how Dougal keeps his cool and doesn't respond in kind. (Sure you can get him a little bit flustered whereupon he may exaggerate a tad - But even that is hard to pick - and who wouldn't under such a barrage of insults as what he is getting? Yet he doesn't trade insults!)

....Most every one here who owns a Toyota, likes and owns their vehicle by choice..........

Which is the only way I see Dougal has "baited you". (Apart from from politely suggesting alternative ways of doing things - Which everyone should have the right to do.)

It is rather "courageous" for him to say negative things about a Toyota vehicle/engine (or promote non-Toyota gear) when he knows lots of people listening own and love them. And if you retaliate with personal attacks - you're bound to get a certain level of support behind you. But such bickering doesn't attract people to this website.

Most of us want to see "a happy family". And one where alternative views are welcome with the aim of improving our overall knowledge-base. eek:Ooooops. Here I am speaking for others without authority again.)

So let's just move on.

No-one will have "lost face" in this. You and Wayne obviously have gathered a lot of respect for your knowledge and mechanical abilities over the years while Dougal's contribution is clearly valued too.

Please - No more personal attacks

 

[gerg]

Actually Otterav I think the point is that you spend more time insulting and attacking Doug personally than you have legitimate posts. There is a reason Crushers thread was deleted and you are every bit as much to blame as he is. You could almost say everything you have said minus the slander and insults and I would be ok with that. How many threads have been destroyed due to you and crushers uncontrollable tempers. Say what you want to say... everyone has an opinion, but I am sick and tired of the 10yr old style communication you guys use.
And Crushers my post was meant for Otterav, not you. Please respect my handle and spell my name with lower case. However, I encourage you to use uppercase in the rest of your posts ... thanks.

All things aside... that is the weirdest clutch fork, erm clutch spork I have ever seen. I have added it to my archives in case some where some time, after civilization has completely collapsed, I can maybe try to tackle the question... ok, wtf was that about?

That's what's known as a "bush repair". The things you do to get yourself home.
The clutch fork had worn thin and cracked when I was far from home, the addition of a large serving spoon and some zip-ties gave me enough clutch action to drive the 500km back to where I had enough gear to pull the gearbox and fix it.
The photo on the right is the same fork welded up.

Four years on it was still working well, but I then changed the gearbox for another Isuzu one with a better gear spread. On another website it was voted best bush repair.

 

[gerg]

Yeah I actually got the "function" part of the clutch spork... it was the timing and chosen venue to post the picture that I was kind of unsure of. I too have some pretty red neck repairs under my belt. Mostly they utilize bailing wire combined with some of the surrounding vegetation.

[crushers]

ingenious...
although i have yet to see a cruiser fork wear that bad, pretty smart bush repair.

<of course you could have driven home not using the clutch, more challenging for sure>

 

[Rig of Mortis]

That's a riot, I had my clutch fork wear right through and my slave cylinder poked through, so I took a Presta valve adapter from my bicycle tire stem and snugged it in the hole, fit perfectly and lasted for years until i came across a doner clutch fork.

The things you do on the trail to get you home.

Awesome.

 

[TOBASH]

Dougal, awesome repair, but did you re-enforce the welds?

Awesome repair, and I'm sure no one's flatware is safe anymore. Welds and the areas around them fail with some regularity, so did you use any metal backing to ensure your repair stays solid?

 

[Dougal]

I added some reinforcement around the back side which you cannot see in the photo. As of last year when I swapped the gearbox over the repaired fork was still working well. It had done around 40,000km since the repair.

Enough zip-ties can fix almost anything.

 

[TOBASH]

Enough zip-ties can fix almost anything.

It's amazing that I have thousands of dollars wrapped up in tools, yet a 3 cent zip-tie can often surpass all of them in utility.

Best,

Flip original 3B exhaust manifold for turbo

i am planning to flip a 3B manifold to install a turbo, questions are as follow

1) I have a lebaron Chrysler 2.2 gas turbo. Is this turbo compariable since it has a carbon seal?

2) Do i have to enlarge the exhaust manifold to match the exhaust port on the head?

3) I have a vacuum pump attached to the alternator. a) Currently the engine supplies oil to the vacuum pump and returned the oil back to the filter housing.. do i run a tee on both of the feeder and scanvange lines , so the oil shares with the vacuum pump and turbo?
b)If so, then i am afraid the hot returned oil from the turbo might flush the vaccum pump, will it happen since the turbo sits higher then the vaccum
c) Finally, the heat from the turbo might radiated to the alternator,

4) Anyone please post some pictures of the flip 3b manifold turbo set up.

Thank you

 

[Radd Cruisers]

I think that turbo has been used successfully by a few Mud members.

You can pull the oil from the alternator and I would drop the oil pan and weld in a return line.



If you search a bit more you will see photos and well written articles on the turbo installations.

Good luck,.

Rob

 

[crushers]

i would not pull oil fromt he vacumm pump. a wasted vacumm pump is over $1500 to replace, run a 't' from the oil pressure guage and as Robbie suggests, drop the pan BUT make sure the return line is above the oil level...any restriction and you will have oil back up to the turbo... not good.
