Well, after posting on this forum that I wanted to go to South-America with my '83 HJ 47, some of you guys (like Canucksafari) said I should turbo my 2H so it would struggle less in the high altitudes of the Andes.

I guess the suggestion kinda stuck in the back of my mind.

So now I'm wondering: Should I turbo it or should'nt I turbo it?

In order to make up my mind, I would need your help to answer a few questions:

Does the 2H have "oil jets" to cool down the pistons?

If not, is it possible to add those jets?

How much does an aftermaket turbo kit cost?

Which turbo kit is the best? Toyota or AXT?

How much power increase can I expect from adding a turbo?

Is it worth the $$?

Is it worth the increased risk of failure?

Are the 2H owners who added a turbo satisfied with the outcome?

Thank you for you input!

The 2H does not have oil jets, Toyota decided it did not need them though many say Toyota itself did not design the 2H. Repco and others here will machine and will fit the oil nozzles but they all say they are not really necessary. Method..The block is turned upside down and the surface where the oil gallery is located is machined flat then bored then tapped and the nozzle screwed in same as the 12HT. The money is better spent on a new 4 core radiator and genuine waterpump or having the rocker arms rebuilt with a Flash crome or Sprayweld rebuild. There are hundreds of 2H's around town here with turbo's, easy when you see them when you take off or crawl off at the traffic lights, very easy to pick. Around Oz there are enough to keep 3 or 4 companies manufacturing kits for them so what does that say? I bought my Safari/T3 kit for $600.00 secondhand some years back and it was put on with a 3 inch exhaust and forgotten about at the time my motor had over 300,000 Ks on it,still no problems what so ever. I can't see any risk that you speak of if the motor is in good condition and the cooling system like wise. Radiators can look good outside but the tubes inside can be blocked and still function with a 30 to 40% restriction and this with the extra performance on a hot day will cause problems-with any 2H or 1HZ. A lot of blokes here will fit the turbo, big exhaust gauges etc and then make excuses why they will not pay $240.00 for a new radiator after theirs has been in the car for 10 years or more.
On performance, Pre turbo, the 2H is like a wounded snail in traffic and bloody dangerous while overtaking at highway speeds between 90 to 110KPH. Some climbs over ranges here require 2nd or even first gear if you can't get a run up. Post Turbo then usually 3rd is required only. Remember these are only speed bumps compared to the mountains in the Americas. Top speed should be increased to just over 140 KPH , diff 4.1, tires 33x12.5x15 mudders on my HJ75. If tuned reasonably well you should have a bit better economy with the turbo if you drive it accordingly but if you boot it you will have less.
Fit the turbo, 3inch exhaust [preferably mandrel bent] new water pump and radiator and pyrometer. Then like me you will wonder why you did not do it sooner. Regards

Turbo it! Install larger exhaust at least 2 1/2 inch! Install pyro!
You will not believe the increase in power or fun you will have after the installs.
Turbo Glide, AXT, or home grown just do it.

Bigbrowndog.

Excellent! Very helpful in making a decision! Appreciate time spent on your reply! Nice to have the point of view of someone who actually went thru the same process and who's surrounded by similar machines.

Thanks!

Short answer... I like that!

My GF prefers a slow ride rather than a turbo ride though...

What about compression-is it necessary to lower the compression after turboing a 2H?

Not sure what you are getting at? Maybe it was lost in translation. Ah what the hell, I'll bite...

The short answer is NO!.

If you want to lower it, then it's a simple process. Just remove your air filter and spend a summer running dusty roads... really!

I like this idea! Very much so!

I'm not really qualified to answer or comment on the question of a turboed 2H, so I'm just going to sit back and listen intently and dream of such an adventure through the andes in my own HJ47

Consider this thread bumped!

I was talking about compression ratio-turbo engines run on lower compression ratio than naturally aspirated-this is done by thicker head gasket...

psi that s%%t up

[Tapage]

just for your reference ... I'm a happy 2H customer, after few years and 14PSI when it's needed .. it worth each dolar on it ..

[HJ47]

I loved my turbo-charged 2H...but I love my Vortec a whole lot more. I get the same fuel economy on the freeway with my Vortec as my turbo-2H got, and I have gobs more power. I never slow to less-than 65 MPH/ 105 KPH or so, even on I-70 going to Vail. I towed my FJ40 on a tow dolly from Boulder to Phoenix, and my troopy was still faster than the turbo 2H was without an FJ40 in tow.

Around town, the 2H got better fuel economy than my Vortec does. However, I don't have any turbo lag now. I sold my 2H/Turbo for more than I bought my brand new Vortec for, and I don't miss that 2H at all. I say save the money on the turbo, buy a new Vortec, and sell the 2H to someone with diesel envy.

Cheers,

Josh

Thanks Josh!

Did you ever have any issues with your turboed 2H?

Curious, how much did you sell your 2H for?

Although I'm sure the Vortec has lots more HPs than a turbo 2H, I'm pretty much sold on the diesel for a number of reasons like cheaper price in central/south-Am, better availability of replacement parts down there too, etc... Plus, there will most likely be 2 of us on that trip and it would make sens, I think, if we used the same type of fuel. Plus, I'd like to stay a little bit closer to stock than replacing the whole engine. I mean, I don't mind replacing OEM parts with different Toyota parts but I dunno about mixing brands... But that's just me...People do it all the time...

Thanks for your advice!

[cruisedeisel]

as in a v8, ouch! definitely not as cool.

go with a 3b-turbo'd

$100= 1000kms, city or hwy. not sure about towing?

[Volcano cruiser]

stay with your 2H and turbo it. PM Tapage for any install or tweaking advice.

Keep those of us who live WAY south of the border up to date on your trip planning and execution. Most of us can provide pit stops, access to mechanics and parts along your route. Post all of this up in the expedition forum where we keep an eye out for southbound cruiserheads.
Good luck,
John

theres a 50/50 chance im heading to panama this winter. still trying to save up. definitely would be nice having some stops where we could steal some parts. j\k

most of the shit that breaks on my truck is the shit that i've built, i don't have shit on toyota's engineers. maybe an on board welder would be a good idea.

i really wanna do it, its be a life goal so maybe 60/40, CHEERS!!!

It's a long term but very serious project VC. In fact, the more I talk/write/read/ear about it, the more serious it gets...

I even found a would be partner! How cool would that be?

2, not one , but 2 HJ 47s heading down to Tierra del Fuego!

One's a wagon and mines a pick-up outfitted with a fixed pop-up camper in lieu of the truck bed.

Thanks for the pit stop offer! Might come in handy, hope not...

I'll make sure I keep you guys posted (litterally...)
