Will be doing a rebuild on a BJ 45 troopie with a 2H motor.

A few things,
I don't want to come up with my own turbo sys. Will use kit only if doing an add on turbo.

I want Mech fuel injection sys. no electrical stuff where possable.

I'm looking at three options:

1. Rebuild the 2H with any up grades avalible, and put on an aftermarket turbo kit. Is there any thing I can do during overhaul to make it better for being turbo'ed?

2. Buy a "better" low mile engine from Japan. And add turbo kit to it. And intercooler. If this option which engine? (mech. fuel injection needed)

3. Buy a turboe'ed and intercooled low mile engine from Japan.
Again which engine. (mech. fuel injection)

And yes I know this is not going to be cheap.:)
Thanks for any advice, would like as many details as possable.

easiest will be a 13BT, way better than the 2H non-turbo.
the 2H/12HT will require a different tranny
if youa re swapping both the engine and tranny then go for a 1HZ or HDT and H55F...
cheers
 
crushers,
Yes will be using H55F tranny.

Is ths correct? 1 HZ is non turbo'ed from factory so will need turbo kit.
The HDT is factory turbo'ed.

Advantage or disadvantage between 1 HZ with torbo kit as opposed to 1HDT with factory turbo?
When replacing a 2H? Will one fit better than the other?

I'm trying to learn as much about these engines as I can. I would like to make the right choise. Since this is going to be a bit costly I reall want to get it right. The engine name and veriatioms can be somewhat confusing, or at least to me they are!
Allen
 
you are correct in your assumtions...

i like the 1HZ turbo'd and have driven both. there is nothing wrong with the HDT, a sweet engine as well, i just like mapping my own turbos...

it is all fun for me...
 
crusher,
At the moment Washingtion State. In less than 30 days Idaho, Boise area.

Do you make/put together turbo kits? If you build turbo systems I would like to talk to you about you putting one together for me.

Also out of courisoty can a 2H be up graded to a 12H with a turbo and some differnt parts at rebuild?

Allen
 
Boise Idaho...
there is a good cruiserhead living there... his name slips my mind right now... good head.

i have installed numerous custom kits but never made one up for anyone yet...

cheers
 
What are your thoughts on just upgrading the 2H to a 12HT with an aftermarket turbo?

What Turbo system would you recomend? If possable I would like to have an intercooler also.
Bullet proof is more important than raw power. Eventually this rig will be used in some real off the beaten trail applactions.
 
Hey Wayne, I think he has the 2H in there already. So it looks like he has an H55 with the H series input shaft, so the 13BT would not be the easiest swap. Correct me if I'm wrong Allen.

Few ?s:

1. Have you done a compression check etc. on the 2H-- i.e. why do you think it needs a rebuild?

2. What is your budget?

3. Why do you want a turbo if you want a bullet proof trail rig?

One key thing to consider: the 2H motor does not have the piston skirt oil cooling of the 3B etc., so it is less turbo happy. If you are concerned about bulletproofing vs. power, I would say that the 2H has all the torque you need and will be as bulletproof as possible sans turbo. Or grab a 1HZ.

IMO if you have the budget and you want to do it once and do it right, I would get a 1HD-T, which should mate to your H-input shaft H55F tranny (?). I think a factory design, tested, and proven turbo motor is always going to be more reliable and easier to deal with than a kit motor, unless you have the skills and shop and evil genius of Wayne to tweak stuff.

A search of the forum will turn up lots of hits for turbo kits. Also, if you search for "2H" and "12HT" and variations thereof you will get lots of hits. Enjoy your reading!

Yes I don’t know why I didn't just use the search button. But I did, and read and read.

I will be bringing one in from OZ. Will do a frame off restore.

It's 2H will have an unknown amount of miles and maintenance history. I really want to start with a known base ie. All new or rebuilt.

Want turbo because it will be driven long distance with a load.

Budget, I'm guessing between 8 to 10,000 with me doing most of the work.

If I understand all this correctly, the 1HD-T with split transfer case and H55 tranny is the best all around swap.

Question then. How difficult or maybe better term, complicated is the swap from 2H with 4sp tranny to 1HD-T with transfer case and H55 ?
Major fab work?
Is the intake and exhaust being on opposite sides on the 1HD-T an issue? I guess that’s one thing that has me concerned, the amount of complication from that. Also will be adding power steering if that would make a difference.

The alternative would be rebuild the 2H (add piston skirt cooling if possible) and use a H55 tranny & split transfer case and AXT turbo kit. Minimal fab work not quite as much power but a good solid setup.

If the only real difference between these two options is cost ie.. fab work not a big factor either way then I will opt for the 1HD-T.

An 1HZ would not really gain any thing would it since I would have to do an engine swap and then add a turbo (for a 1HZ wuld go with Safari turbo)

Or is there any advantage to a 1HZ with a Safari turbo & H55? Over the 1H-T? Even just avilabilty of engines.

Sorry for such a long post and so many questions. I have been using the search button to. I really appreciate you guys advice.


Do I understand the options correctly?
 
Okay so was the 2H original or a replacement? I.e. is the rig an HJ or BJ45?

Since you are set on the turbo, I personally would think a 1HD-T+H55F would be the easiest and most reliable engine combo. YOu can get the engine+tranny mated together with a t-case, and then you have a known low-mile single unit that you can swap right in with maybe some fabbed up mounts. You should consider though getting a half cut truck as it will have all the electronix. The 1 HD-Ts you can source through GSCruisers are JDM units, meaning they are from Right Hand Drive trucks, thus limiting some of the fitment issues (maybe). I can't remember anybody doing this kind of a swap, though, so who knows.

Alternatively a factory 12HT would fit right in, no tranny required, probably cheaper.

I still kinda think though for bulletproof simplicity the 1HZ sans turbo is the way to go. But I hear you about the highway...

I am by far one of the least experienced people on the board, so I am just communicating what I've learned here on MUD--there are many more people like Wayne who have businesses etc. that deal with TLCs so hopefully they will chime in some more.

Will be a BJ45 with factory 2H.

With a 1HD-T or 1HZ do I need a new radiator?

Yes with either a 1HZ or 1HD-T would most likley get a engine, T-case,tranny combo from G&S Cruiser.
 
On the other hand, if you are going for an engine tranny combo, then I would have to go back and agree with Wayne on the 13BT+H55F. Nice highway cruiser, more than enough on the trail, proven reliable, great mileage/economy, way cheaper (?) than a 1HDT.

As a 3B driver, I personally don't think I would need any more power than a 13BT.

Dunno about the radiator. I don't think it would be a question of cooling capacity, rather hose and port placement issues.

I just did 2500klms in a heavily loaded 75 series with a 1HZ and the power was great for overtaking.
I had to think and wait but it got me around 160 ft long road trains ok.
A 45 will be a bit lighter and therefore faster.
As the 1HZ is just coming out of production ,parts will be around for a long while.'
Fit a 1HZ and enjoy it stock for a while and add a turbo later if required.
 
Ok, me confused. It will be HJ45 and HJ47 is same just later model yes?

So HJ45 with 2H from OZ. Man this sure doesn't make me look so bright:rolleyes: !

I had thought (there's the problem) I saw them called BJ45 Troopies.
Thanks tlaporte for the correction.

Allen
 
I thought here all is about money .. with enough wallet you been able to buy a new 1HD-T engine, voots it to 14 lbs and intercooled it with really nice performance :D
 
Close, but ...

Almost:
HJ45 = H engine (?? - 1980)
HJ47 = 2H engine (1981 - 1984/5?)

Europe and South America seem to have gotten the B-series Troopies, and Australia (and Africa?) got the H-series, from what I've gathered.

I'll be curious to follow your progress with the power-plant upgrade.

I'm anxious to bring my HJ47 soft-top troopy over from Oz next year, but for now the 2H will have to suffice. SWMBO dictates that bringing the truck over will be enough spent on my toy.
