I did get the custom turbo system installed and running in the 1980 Toyota Land Cruiser HJ45 Troop Carrier. I’m pretty impressed with the power gains. Unfortunately I went the cheap route and used an aftermarket head gasket. I’ve already blown it. I’m searching now for a better option. Hopefully the OEM Toyota gasket is still available.
If you’re curious about it here’s a video I shot in the garage shortly after I got it running.
You can see the intercooler plumbing running from the turbo in front of the radiator and over to the intake manifold.

Cool turbo Troopy mate.
he i have a hj45 utillity and am about to embark on a full rebuild and i am seriously considering a turbo, if possible can you email me with a break down of how you went about your turbo set up and specs that i need for the engine rebuild as i have searched everywhere for it and your site is the only one with a bit of detail..!!
any info, photos diagrams ect would be really appreciated as this is my first rebuild and not many peopl i know have wanted to do up a H engine so i need HELP PLEASE!!!!!
If you haven’t previously rebuilt any engines then tackling a diesel as your first project is going to be a very difficult challenge.
These old diesel engines are simple machines but they require many special tools and knowledge of the various processes involved.
I would get a copy of the Toyota H Series Diesel Engine Factory Service manual. They pop up on Ebay in the US and AU from time to time. You will absolutely need a copy of this manual. I’d recommend this as a starting point. Read it and get a feel for the rebuild process before ordering any parts.
You’ll most likely need to order an engine rebuild kit from Australia since these engines were never sold in North America other than in fork lifts and other industrial equipment. (Don’t use the fork lift rebuild kits listed on Ebay. There are subtle differences in the industrial and automotive versions of these engines.) The company you order it from will have a series of questions about your engine. You’ll be able to better answer the questions if you’ve read the Engine Factory Service manual.
As for my design of the turbo system it’s all very basic. These old Toyota diesel engines aren’t high performance. They rarely see more than 3,500 RPM so I decided to go with a log style manifold for simplicity. As a general rule a turbo suited for a 2 liter to 2.5 liter gasoline engine would work well on a 3.4/3.6/3.9 liter diesel.
Engines are just air pumps. They move a certain amount of air every revolution. You pick a turbo to match the amount of air your engine pumps. There are lots of websites that can help you in this respect and a couple of good turbo system design books out there. (I think one is by Corky Bell but I forget the name of it. It’s on Amazon.com)
I’d be happy to post more photos.
what i meant to say was it was my fist diesel build i have majority of the tools and equipment i would need i just can’t find the specs or a manual i have been looking for one and can’t find one i’ll keep checking ebay but if you would post more photo’s that would really as for your log manifold i think its brilliant and exactly the way to go..
thanks!!
