I have a 95' HZJ80 that i bought rolled 16 years ago. It had 220k on it. I repaired and chopped/extended it. It has a DTS turbo kit in it which i reckon would be 20+ years old.
When it rolled it must have picked up something from the aircleaner, i didnt notice anything when i test ran it at the wreckers but later it smoked and ran crap.
I pulled the hose from the turbo inlet and found a lump of rubber hose in against the wheel..
I had bought several trucks from the guy so he had it rebuilt.
Fast forward 16 years and 100k later. I change oil at 5k, air and fuel filters every other oil change, and i have averaged 6000k's a year since owning it, tho the last couple years been using it as my daily.
We took it to qld at christmas to see our daughter, and got stuck there due to covid, couldnt get back thru NSW. So after a couple weeks we decided to head to Birdsville and come home thru SA. Was an amazing adventure, and ive come home with a new passion for the old truck and super keen to use it more. If anything lockdown did, made me more appreciative of the times away from the city.
Anyway, ive been following threads on here for years, lately taking lots of notice of this one. I need more power.
The truck runs really very well. Had the shims done before we set off in decmeber. But have not done the injectors or pump since owning it. And not felt it needed it, it really starts well always does what i want. COming thru the bridsville track, which is pretty flat, it sat at speed fine, across the outback as well, flat country no problem. But come up to a hill and its back thru the gears.. We had a light load at christmas as we were not camping. But do camp regularly and want to refit the tray with new kit. As light as possible.
I feel like its a good candidate for more boost, so have sifted thru info, looked at the ebay options, and was kinda settling on a grunter for a while. But am wondering a couple things.
Is it worth modding the turbo i have? I should have taken more note of what blade it had in the exhaust side, when i had it off in december fitting a pyro sensor.
Its a TD05H with a T3 inlet and a 3 bolt dump pipe mount, internal gate. My memory gets cloudy these days but im sure the manifold had twin entry, cant recall if the turbo did.
WHat id love is to keep momentum up a reasonable grade. I reckon it could do with some timing adjustment as well. After replacing the timing belt recently, it picked up about 20% more power, and putting the belt beside the new belt, it was noticeably stretched, which i cant explain, was not an old belt at all. I might start a post about that.
To get an idea of what boost was in this old turbo, i disconnected the gate and took it for a spin. It makes 10psi tops and thats about 3000rpm up, guess as i dont have a tacho, and it spools pretty slow, guessing around 2000rpm before it gets past 3-4psi, hits 5psi and dawdles to max.
After disconnecting the gate, it felt stronger from the start, and reached 13psi tho faster. In fact in autumn weather just me and the dog on board, it is pretty good.
Looking at options that keep the manifold, hence costs in check, i found this one that also has a 3 bolt exhaust flange, so win win. A reasonable bolt on upgrade?
I have also got a couple of boost compensators in my ebay cart, but am not fully clear on whether any of them will be ok, or if theyre more pump specific.
I have been considering bigger changes, engine swaps as well, doing the sums for new turbo, IC, new pump and injectors, gee that climbs up in cash pretty quicky, making an LS start to look good
