thanks more fuel it is! going for test drive now see how it does with the max spring installed in the wastegate

@veiloctane what turbo are you running again?

Kinugawa TD05-18G I believe.
I’m on a TD06SL2 18G 8CM
6+6 billet wheel
9 blade exhaust
Same turbo as this but 8cm housing.
Can’t see the turbo but is burried in there.
Kinugawa Turbo 3" TD06SL2-18G Toyota Land Cruiser 1HDT 1HD-T 1HD-FTE
Description Kinugawa Toyota 1HD diesel td06sl2-18g spec turbocharger with 3" anti-surge cover and stock a/r 8cm bolt-on turbine housing. The turbocharger is equipped with CT26 base turbine housing (inlet and outlet type), the same as the factory turbocharged 1HD Land Cruiser engine. You will get...

Just a update I’m getting 18PSI now after changing to the 2bar spring. I didn’t have the 2.5 spring in my in my waste-gate kit.

Runaway shut-off valve. It’s pull cable activated.

Sometimes I’m getting perfect AFRs I really need to find a long steep hill to tune this better. AFRs bounce all over the place.
AFRs in a diesel will be all over the place.
Constantly changing.
Depending on throttle position, engine speed, engine load, boost etc
Your really just looking for a peak to be sure you're not overfueling.
If you had sustained AFR of 18:1, it would show up as high EGTs.
Reading both in conjunction gives you a read on your tune.
Also, if you were seeing AFRs of 18-20 when you're at full boost, you're probably running too rich.
The screen shot of your gauge above, the graphics shows a rich condition as blue, or green suggesting its giving you a cool running condition. That is true for a gas engine, not true for a diesel. I wonder if the graphic is able to be changed to show rich in orange and red colours for a diesel application?

yes the application does allow me to set ranges.. i just haven't done it.
I figured out why I can't build boost I inserted a borescope into the turbo air outlet and I found a crack. so sad

What that's BS!
I'm not sure if that's the housing or turbine rotor. Manufacturers issue
Yes I'm waiting on RMA. they said they would send it to my email...
all this time I thought it was something I have done or missed....
glad I had a borescope to check inside the compressor outlet... first time I have seen an issue with the housing
perhaps under higher boost the crack opened up and now the compressor wheel touches the housing... I was driving and I heard a loud POP and lost all boost... I was not far from home so I just idled it back no power.

Oh man that's a real shame. I feel your pain from here, I had been hunting for issues like this, maybe I do have a small Crack in mine aswell. This is bad news but hey some one will benefit from all the hardship one day knowing that you'd done your due diligence.
I bet you were thinking oh its just an intercooler hose when you heard the pop.
And good old borescope. I don't have one of those yet but I need to invest in one.
Your right. Thought just a intercooler hose. Pulled over for that to check but nothing. Borescope. Get one!! I got mine on Amazon it’s Wi-Fi and pretty affordable. Also has dual lens.
Thanks for the kind words. Yeah it’s a bummer but at least it was only the housing and nothing major like metal pieces coming into the engine.
I got lucky there with the factory turbo when the shaft broke in half and I also had a runaway. But compression test and leak down test was still good and within factory spec. Also pulled the oil pan to inspect for any turbo pieces but none were found in the oil I was able to get it shut off that’s why I have a shut off valve now. Runaway is pretty scary.
So hopefully the RMA process is easy.
I purchased the turbo back in September of 2022
It’s been a year and never thought to inspect the housing. Been collecting parts making mounts fitting intercooler. And now this from a defective housing. I guess I’m lucky. Hopefully turn around on parts is quick.
I’m just bummed I didn’t even get a chance to turn up the fuel.
Oh man, that sucks.
Check your intercooler and pipes for shrapnel
Check your intercooler and pipes for shrapnel
Pipes are clean and dry no oil in there. No metal no runaway this time. Lucky again.
Looks like it shifted the whole shaft. Breaking a tooth on the exhaust turbine and the front just touched.
No leaks from both coolant and oil so what gives so wierd. Just my luck.
Now just waiting for parts to come in. Glad I’m still under warranty.
yeah, that's what it seems like pretty crazy... I checked my lines nothing is clogged no lines are pinched including the oil drain.
What's odd is no oil or coolant leaks or maybe I just stopped it in time
I'm wondering if the thrust bearing is gone from air box restriction but I don't think it is a brand new Wix air filter.. unless the paper is really that restrictive. I do have a Wix filter minder and when boosting to 10psi or even pulling the throttle cable in the engine bay you can see the filter minder maxing out.

Get a genuine air filter and see what the restriction is like.
Agreed.
It's hard to beat the OEM filters, and that's not said through unchecked OEM OCD, but from personal experience, and reading several different testing reports
