Best turbo for 1HZ for towing purposes and daily driving? (1 Viewer)

[joekatana]

It seems when it comes down to getting a turbo for a 1HZ/DT engine there is a lot of choice and certainly big price differences ranging from 200$ for cheap Chinese knockoff CT26's models to +2500$ Gturbo's. I am not looking for high performance but just some help to pull a trailer over the highway at highway speeds and will ad a top mount intercooler.

Right now I have been looking at the Mamba and Kinugawa turbo's but their are a lot of choices to make for size and boost.

Are there people here running these that are not interested in zero to 60 time but care more about overall performance and keeping everything in one piece ? I have a super low miles late model 1HZ in my cruiser and am not planning to replace it anytime soon

It seems that going to a smaller turbine makes it spool up faster and will help me more in the mid range then the larger ones.

Smaller exhaust housing will aid spoolup, but a smaller compressor housing can choke mid-top end.

There's a huge amount of info on this in the "The 2H/12H-T/1HZ/1HD-T/1HD-FT Gturbo Alternative Tech Thread " thread.

Thanks and I have no doubt that there is a lot of info in that 89 page tread but it is hard to find info that is not as much about top end performance but more overall drivability and usability . I started reading about 10 pages in that tread and saw that Mamba and Kinugawa are both mentioned there several times but not much real life experience with either of them in racking up miles or towing.

 

[IanB]

The guys running Mamba and Kinugawa seem to fade away after installing them...no "my turbo blew up" threads, but no "this cheap turbo is 100% the way to go" threads either. Starting about 2/3 through that thread would be your best bet to find feedback from the pioneers running those options.

The best turbo for driveability will build boost early, and have the legs to carry the boost into the higher RPM's without choking, the best of both worlds if you will, and you'll likely have to pay the piper, or accept the limitations of a cheaper alternative.

Adapting an OEM 1HDFTE turbo to the 1HZ would be a pretty good option. OEM reliability. Quick spool from the small turbine, and higher flow from the larger compressor (as compared to a standard 1HDT turbocharger).

How much weight do you plan to tow? If you plan to tow lots, a 1HDT is a better option than a turbo 1HZ. Way less heat to deal with.

I have plenty of 1HDT/FT’s available if needed but right now I have a 1HZ with 20k miles on it and I would like to run that for a while , I have a manifold from a 1HDT here with the oem turbo still on it but no idea about the miles or condition of said turbo. The intercooler should take care of the heat and I have used many HZJ7x’s in Europe to tow 7500# without any issues once you lifted up the hood a bit in the back to let the heat escape.

I know it is way hotter here in Tx and going cross country the headwinds are stronger then in Europe and way more elevation differences.

I just took this Troopy on a trip from TX to Northern California and back and as long as there is no headwind ir I am not running at elevation it pulled the 7500# trailer I was hauling but 70 mph was the max . It has no altitude compensator on it so I will install one if those also , not looking to make this thing tow like my Ram2500 with the Cummins but at least be able to tow my crawler so I can sleep at night in the pop top and wheel the HDJ73 during the day.

 

[IanB]

If you're planning on turboing it I'd go with a boost compensator so you can tune the thing properly rather than an altitude compensator.

Maybe you'd be best off rebuilding the stock turbo you've got for your goals?

Not sure if you have covered it yet. I replaced the factory exhaust on my turboed 1hz 105 series with a 3" exhaust. The difference was huge in terms of torque and EGT's.

That would be the next step and just make a short side dump exhaust

Joe, next time you're in Austin, you should test out my 1HZ powered FJ60 with the 1HDT-FE turbo. It spools up nicely and I haven't had any issues towing my small Bantam trailer with tent. My EGT's have been under 850F. I'm also running a small intercooler up front.

@mudgudgeon turned me on to the 1HDT-FE stock turbo and it has been a tremendous upgrade so far.

Did you buy a new turbo ? Is that also a CT26 or a different model ?

It's basically a CT26 cold side coupled to a CT20 hot side. Toyota's own hybrid.

 

[davegonz]

Joe, I bought a low mile used one off the Aussie 1HDT/1HZ Facebook group. I then rebuilt it myself and had it balanced locally.

 

[davegonz]

Joe,
Talk to Galen @bottombracket about sourcing a turbo. I think he ultimately found a new 1HDT-FE spec turbo from MMP.

 

[Indestructible 47]

You can have my FTE turbo for the right price, has 9000kms since a rebuild. You just have to convince me that i need a gturbo to replace it but......

 

[bottombracket]

Joe, I tried to find a used OEM FTE turbo out of Australia like @davegonz, but in the end I went with a newly rebuilt MMP FTE turbo. The builder was in close communication, built it and shipped quickly. All in all, $1000 US to my door. I haven’t run it yet but after driving Dave’s 60, I think will be a good turbo for my daily driving.

Wanna borrow it? C’mon down.

 

[mudgudgeon]

If you're looking at the mamba or kinugawa options, turbine size is not the only factor to consider for spool up.

The one you like in your first post has a 9 blade turbine. This will take a little longer to build boost, or will need a hotter tune to get it to spool, but at higher RPM won't choke because it's less restrictive than an 11 or 12 blade turbine.
11 or 12 blade turbine will spool up earlier, but will restrict top end flow a little more.

For a 1HZ, you need to avoid a hot smokey tune at all costs. Combustion heat in the head and pistons is their Achilles heal. Particularly if you have a late model 1HZ from 98 onwards as they use a lighter piston.

An altitude compensator is of limited value unless you're changing altirude a lot and regularly IMO.
A boost compensator would be advisable for 1HZ as it lets you manage the fuel better to avoid overfueling and high EGTs.

An EGT gauge is also essential with turboing the 1HZ IMO. Again, combustion heat kills them. EGT gauge helps you learn how to treat your baby right.

3" exhaust is another essential.

I would do everything possible to avoid a top mount intercooler, and fit a front mount.
Top mount is the lazy option, and is far from ideal

Don't tempt me

Found out that one of the guys I know works for a local shop that specializes in performance turbos and they quoted me 275$ to rebuild the 1HDT turbo so I might just bring a 1HDTFTE core with me from Europe and have it rebuild, I know a shop that has a crate with around 50 cores sitting in it and last time they asked me if I wanted some

I know that top mount is not the best solution but planning on installing and ARB bumper with a Warn M8274 and some lights so I am already restricting the airflow enough without trying to squeeze an IC in front of my Ac and radiator. I just ordered a 07+ hood with the scoop so top mounted it is

Good info on the blades for the turbine

EGT is a must together with aftermarket water temp gauge and just for fun a boost gauge , exhaust will be done also. This is not my first 1HZ turbo I was just wondering if anyone had searched for the perfect towing setup rather then the "hotrod" version

I am planning on taking this cruiser cross country a few more times , here in Texas we are almost at sea level give or take a few feet but going to California or straight up North I am passing several 6000 ft points and right now it is starving at anything above 4000 ft , the Turbo and IC will help there but I am not sure how much.

 

[bottombracket]

Crap, bring another FTE core for me....add it to the pile....
