I am thinking to go single turbo conversion,one of my mates selling a TR43 turbo,its rated for 450hp.When i looked at the specs its manly for 1.8l and 2l cars.My freind saying because of IJZ 2.5 l It should spool quickly .He asking $550 for the turbo.What you guys think about TR43?

TR43 is not going to archeive much power. The .63 TR43i is some thing made for 1JZ and RB25 engines for 300rwkws. We build with Garrett and Mellet Parts in Australia so quality wise its no problem. As far as I know there is no one here have had one of our turbo failed so far. But Do feel free to compare results.

Tao, there is 2 people mate who have had theirs fail so far . But they probably never contacted you as they just wanted to move on and get some quality genuine HKS or Garrett turbos instead .

I back Daniel up on this one.... It's obvious that you don't take note to your customers Tao! Nor care ... As Dan has stated there has been two that have failed... Hahahaha Guess what Tao! My garret has lasted longer and still going strong... At the end of the day it come's down to support and quality along with good product's ..... Garret is a big company and has been in the business for years... And has well and truly proved itself... Were as you are just new to the business... Only those that want to save(Try) dollers will go to company's like yourself... It's a case of what you pay for is what you get....

Daniel. I seriously haven't yet had clams for the 1JZ TR44x turbo failure so far. I do keep in contact with my customers from time to time. There has been one account that a TR44i was sent back for checkup, and one sent back for .84 rear housing upgrade. If you do know people that did have it failed please ask them to contact me.
Understand that Garrett is a experienced company specializing in Turbochargers. We've been sourcing parts from them since mid June 07. So all of our current turbochargers are build using Garrett components, and its pretty rare they do fail. But I do want to know the reason that caused its failure if there is one.

Hey Stao,
This is what happened to my TR44HF. The compressor blades started rubbing on the housing.
This started to happen only two weeks after I send it back for a service. Because of the leaking lead blast from the turbine shaft. I think what’s happened is that when the lead has cooled the shaft has become un-balanced.
The reason I have not bothered to contact you is because I am over taking the turbo on and off. I have sent it down to you three times since I have had it. Twice because of a leaking seal and lastly because of the led leaking from the turbine shaft after they over drilled the turbine shaft face for balancing.
I just want something I don’t need to mess around with. So I got a new Garret GT3582r
I am not sure if I just had a lemon (mine was the first gen TR44HF) Nevertheless, Stao has always been prompt in trying to help out.

That is very sad to see this. When it came back the lead fill was removed and the compressor wheels was re-balanced. The shaft was tested straight, and every bearings and seals in the bearing housing is made by Garrett.
I have a feeling there might be some thing dropped in and got machined by the blade as there is one deep mark on the inner housing. The clearance between the wheel and housing is just under .5 of a mm.
I still hope you to send it back for analyse as we also do want to know the cause.

o well at least you brought a decent turbo now not like before. it has been proven time and time again.. i dont think i would run one even if it was given to me.

Tao - the issue with that turbo is the fact that you have lead added to the compressor wheel, which has done a good job of removing itself due to heat and then making the turbo out of balance.
Garret bearings or otherwise - if the turbo is not balanced - the shaft will hit the bearings on boost and wear them out. That turbo has bearing failure from not being balanced and premature thrust failure as well causing the comp wheel to machine the inner bell mouth of the comp cover.
The compressor wheel MUST be a homogeneous metal and material must be REMOVED from the comp wheel in order to balance it properly. If you stuff it up whilst balancing - its a throw away job and you start again. New turbos and exhaust wheels + shaft need balancing and a lot of material removed from the comp and exhaust wheel.

No. The lead has been drilled out and the whole shaft has been rebalanced. So there is No lead in it. There is nothing that can come off the comp wheel. Even if it does as when metal land on the wheel it will cause chip o the upper blade which in the photo it is clean.
There isn't issues with our balancer either, apart from the turbos that we make we also repair and assemble Garrett BB units as well as truck units. We've not have had a turbo that failed due to balancing issues. Also if it is due to balance issues the amount of damage on the Comp wheel will be lot worse then what you see.
We take R&R very seriously, By examining those photos we can see the Mark on the comp housing is at one spot.
Which means the turbo might be pulled apart for housing rotation with the comp housing wrongly installed.
Or There is a object that entered the comp housing. as you can see there is black material stuck to the damaged spot. For this material to stick it’s and caused tinny damage to the blades, Its unlikely to be metal, it has to be some sort of silicon product, likely to be plastic or rubber. It can force the blade to one side and rub to the opposite and bend the shaft.
That’s about all we can think off by looking at those photos. To solve the puzzle we need to see the actual turbo.
Black material is probably just oil from the intake, very common. Even my garrett setup had a black film in the compressor housing, but the blade itself never touched the housing.

Yeah the black stuff is oil. It also had a slivery / grey oily film. I think it was oil + steel powder from the turbine fins rubbing on the housing.
There are no chips in the turbine blades. However the sides of the blades have a 90 degree edge on them from rubbing the housing.
The turbo still ran ok but it would make strange sounds under boost. And there was quite a bit of movement of the turbine shaft up and down. I watched it move up and down as I revved the engine and the BOV (SSQ) fluttered you could see the turbine moving up and down.
Nevertheless it was still very tight backward and forwards.

Also Tao! The cheap replacement ct12a's from china also worn one side of the comp housing... BENT SHAFT!..... NOT BECAUSE OF AN OBJECT! Plain and simple Tao! IT FAILED!

Jeff. This shaft is not bend. We would not put a bend shaft we measured it to make sure the shaft's tolerance is below 1 thou and clearance is between 20~30 thou to comp cover. All turbos are made locally with very knowledgeable turbo engineers. We also do turbo overhaul and build with same parts and equipments with same make parts on trucks and cars and this problem is not common.
Also if its made with a bad clearance, first of all it can never leave our factory, 2ndly that would be rubbing as soon as you start the car. It will not wait for 2 week before doing it. This case is very strange.
For a turbo to fail, easy. just throw in a screw it fails, not enough oil = fail, No coolant = fail, dirty oil = fail, blocked oil return = fail, bad fitting position = fail list goes on.
Importance is to trace why it failed, Is it due to our workmanship or is it due to other causes.
So Grant please have it send back for analyze and we will explain why it has failed with photographic details even it is due to our workmanship.
