What kind of turbo for a 2H?

[theMule]

Here's my story...

Bought a turbo'd 2H from a guy who used to own a Cruiser shop locally, he had rebuilt the thing from the ground up and added a Toyota turbo (not sure which one because I haven't pulled off the heat guard). I got a chance to drive it before he pulled the motor, however I wasn't particularly impressed, I really felt no turbo kicking in at all. I am spoiled though because I own a 02 Cummins pick up with injectors, chip, etc. that gets up and hauls ass! I know these motors are not meant for that kind of thing, but I just thought it would be better than it felt for a diesel.

Now I am wondering what kind of turbo you can run on a 2H, and maybe more specifically how much boost can you safely blow into one? I always felt that the Toyota turbos were't that impressive and thought of going with a garrett or holset, but I'm in the dark on all of this and open to any and all info. Maybe my expectations from the 2H is out of line, however I am just wondering what one can do to wake it up! It is after all a diesel...

Anyone out there know much about the turbos or boost for a 2H? Anyone know if the injector pumps can be turned up to increase performance? If nobody on here knows, do you know someone who does?

no offense but ya gotta try the search function.

2h turbo's have been talked about numerous times. And it not going to compare with a cummins.... period.

No offense taken, I've tried the search option... always do before I post, however haven't really found the specific info I'm requesting... that's cool if you don't want to chat, I just thought most folks here on mud enjoyed helping out a fellow Cruisehead.

I understand that it's not a Cummins and never will be, I drive plenty of 2F's and have driven a couple of 2H powered Cruisers. I also understand the difference between a Cummins out of the factory box and one that's been juiced up, whether it's mechanical injection or electronically controlled, the difference is night and day. If this kind of a difference can be had with a 2H then that's all I expect. If you just prefer talking to only your buddies on Mud then I guess that's what you'll do???

I too came from a modded Cummins Turbo Dodge so I know where you are coming from. However, the 2H is an IDI engine that was never really intended to be turbo charged from the factory. I think its a smooth, long living power plant but it will never be capable of the monstrous power. Most seem to say to keep the boost around 8-10psi on these. Do you have boost and egt gauges for it yet?

There are a metric boatload of threads on how to play with the fuel on a Toy diesel. Here are some:

Most of these are not specific to the 2H but the principle is the same.

it has nothing to do with not wanting to chat. Mudders always help.

But if you look around there is lots of info. But it takes time to find.

For these engines to be able to get more power out of them, you can run what ever turbo you wish and install pyro gauges and boost gauges. Then you can simply turn up the fuel on the injection pump till you hit maximum egt's.

hummm, as BB said, use the search engine. that is what is it is for...

let's see, you don't know what is on there now.
you are comparing a 4.0 with a 5.9.
you want suggestions on impoving a dud of a motor.

i like the post above, no offense taken... well, i'll take offense to your post. BB helps almost everyone out if he can, he made a suggestion and you come back with, what seems to be, a smart ass answer.

i do not think anyone has tested how to make maximum power out of 2H since it is not sleeved, not designed for a turbo (although it responds well to one).

you could stick a mapped turbo on it, then intercool the sucker and add Propane injection. lets see 125 hp + mapped turbo 30%-40% (37.5 hp) 162.5 hp, + intercooler 20% (32.5 hp) 195 hp + propane injection 20% (conservative) (39 hp) = 234 hp.
longivity might run anywhere from a few hours to a couple years, you will definately shorten the life span of the engine.

of course you could go with larger injectors, machine out the prechambers (might need starting fluid after that (which is brutal on the mains)) or a host of other mods, research will be your friend. personally you are going to be dropping a hugh chunk of money on a lump of cast.

of course you could do the tests and post them up for the next person who wants to know how to improve the 2H...

why not start with a HDT and go from there? 170 hp to start and should be pretty easy to get 300+ hp out of it...

Thank you much for your responses... all helpful and I appreciate it!

You can tell from my posts I don't spend as much time as others on here, I do however feel that sometimes because of that I'm being shut out or tossed aside. I'm not trying to be a smart ass or cause problems, all I would like is a little respect and common human decency. There are people every day joining the Cruiser family, newcomers that have questions, I think a positive welcome and kind words is what fellow mudders should post up, but too many times some are quick to jump down their throats for posting in the wrong section or such. I know I don't have 2000+ posts, but I don't have a lot of time so I get on when I can, and I gotta start somewhere.

Thank you, that's the thing I just bought it, it's not even installed in my Cruiser yet. I just don't even know the first thing about the 2H, that's why I'm asking. I know there is a wealth of knowledge on this board and I look up to all the members, especially those who have been in it for a long time and know from experience the things I don't.

Thanks again.

[crushers]

seriously, the folks here on mud are the greatest persons to deal with, they are very helpful, usually very considerate and compasionate. the amount of posts mean nothing really, some like to try and help more than others (or some of us just like mud and hang out here more than others)(or we have less complicated lives so we have more spare time).

i highly doubt you will find a site where the members will help you as much as they do here.

respect is earned, common human decency should be displayed.

i think the biggest problem with your original post was as BB said, this has been hashed to death and there are many threads on turbos to research...i don't think anyone was shutting you out, we just didn't have anything new to add to the discusion...

you have 275 posts so i don't think you are new to Mud but either way:

welcome to the Toyota diesel world...so tell us more...what you are installing this engine into? a 40 or a 60? or???

Ahhh...first thing I would do (and did) would be to download the 2H engine manual from birfield.com. That will at least give you the basics of the engine. So what are you going to put it in?

Cheers, Its been pretty well outlined by the above posts. I run a T3 on my 2H. You can also modify the cam as is done here. Hypatec also make a set of good oversized pistons with a steel insert under the second ring which is better for the turbo.. The early 2H motors were wet sleeved motors so the later ones can be rebored the same though I do not understand the benefit of this, finished and semi finished liners are available. The pump and injectors can be retuned for the turbo. Polishing the head seems to make little difference to the 2H, have mates who have had this done and did it themselves. A balance seems to be favored but apparently Toyota's balance job is well and good for the rev band the motor is capable. With a decent turbo and exhaust I am sure you will be surprised by the 2H keeping the motor in its correct context.
Personally I did not respond to this post because I have done this on several occasions and then it is usually followed up by requests for pictures which when I was on dial up took ap 20 minutes each to load and after grinding away for an hour or so most would never bother even to say thanks. Same for copying pages out of the manual they take longer and after an hour or so one wonders why bother. We all try to help, thats why we frequent the forum. Most of the guys are great and are helpful back as well but there are a few that are LOL "it's just about me".Have you thought of sourcing a 12Ht I think it would be more what you are looking for, see Zanders post and others, straight bolt in more or less. I agree with Crusher , you won't find many mods on any forum as helpful as BB these guys have a life and family as well. cheers

Thanks Wayne for your input, I would like to live on here but time is a resource I have very little of. I agree with you that these are the best people on earth here on Mud, I've dealt with some amazing people that go above and beyond to help. I've just been jumped on by a couple of people a while back for things I really don't feel were justifiable, I'm sorry if I jumped to conclusions on this topic.

I had the opportunity to purchase the 2H-T from a local guy who added the Toyota turbo, I looked yesterday at the castings on the turbo to try to shed some light on which one it is because I've seen the CT26 before on a 22RTE set up with that in the casting, however this one has nothing but "TOYOTA" cast into it. I am going to run the 2H in a 73 FJ55, I also picked up a split case PTO and winch from the same guy when I got the 2H, so my plans are to run a H55F with the set up. I'm pretty stoked about this build! I know quite a bit about how diesel engines work from a friend who's dad is a diesel mechanic, but I'm learning everyday. I'm not pig-headed and I'm very open to any advice because I know there are many avenues that one can take. I know that those in Australia and Canada were the lucky ones who see many diesels and have had the opportunity to be around them. I picked up the motor because it was here and I didn't have to ship, etc. Also I'm very passionate about diesels and how they operate and the torque, etc, I'm perfectly happy chugging along. I'm not a performance guy, all my other Cruisers have 2F's and I would never dream of a SBC conversion, I'm very pro-Toyota and like to do complete Toyota set-ups, that's why I got the 2H instead of a Cummins 4BT or something else. I believe keeping it with factory stuff makes it a Cruiser and gives it the feel I appreciate. Vintage is what I'm about so i don't mind what the 2H offers, I just thought I may improve it a little if I'm able safely, but I don't want to shorten it's life by doing rediculous mods either.

Sorry if I was beating a dead horse by opening this topic back up, but I do appreciate the feedback!

Thanks BBD, I appreciate you taking the time to post the pics, that is worth a thousand words!

Thanks to all those who posted, I genuinely appreciate it, I will try to dig in deeper on the search function to see what I can find.

Take care all!

[crushers]

a 2H-T in a 55 will make a sweet assed rig!! the performance will be a bit short of a healthy 2F but it will be close and the fuel milage shoudl be just about double the 2F...
congrates
you shoudl do a write up on the install with pics, sounds like a nice one...
