Hey guys,

I recently bought and got installed an apparently "good condition" second hand hypergear tr43 turbo... which when I bought it had a chip on the corner of one of the fins probably about half the size of this zero: -0-

When I asked the mechanic if this was ok he said it was fine.... I was skeptical... how can something that has to spin at such a speed and maintain a constant high output while attempting to stay in the exact same spot be ok when it doesn't have perfect balance? none the less I went through with it.....

I am meant to have a tune in a week by dr. drift.. who I hope will fix the slow spooling issue... because I am only getting full boost by about 4,800-5,000 rpm... an issue I am not sure if being caused by the chip....

I also am hearing a slight whistling sound when I drive... but that could be my dump pipe and the back of the turbo not being sealed 100%?

I saw hypergear (Tao) who said he doesn't think it is a smart idea to run the turbo if it is off balance at all because at high rpm it will wiggle a little and then start destroying seals etc etc...

I have spoken to the mechanics again.. who said they would give me the money back for the turbo... but I will have to be charged labour if they take it off again.. I am thinking i may just do it myself and replace it with a brand new tr43 myself...(because it will fit identical so no customizations that I will have to worry about)

I need some more opinions desperately! DO YOU THINK THE TURBO SHOULD BE REPLACED? OR WILL IT BE OK AND RUNNING CORRECTLY? tell me you honest opinions because right now I am so confused what to do...

Much appreciated,

Adam

Personally i wouldnt do it, in my opinion it would be slightly unbalanced and over time (who knows how long) could get worse and potential throw the balance of the wheel off and make it start hitting the housing.

you have to ask yourself, why is it chipped, what caused it? did something get sucked into it and chip it?

where did it end up? what the hell has enterd the turbo? and what might have passed through it?

basically, id be taking it off yourself, returning it to whoever sold it to you.

If it lets go your motor might get a mouthfull of metal

Thanks for the advice guys, really does help me rule out what to do....

this is the update from today and me spending about $50 on the phone bill to the mechanics and Hypergear:

Mechanics: The turbo they showed me they would put in my car (with the chip) "apparently" IS NOT the one that is currently in the car but the exact same model...

Hypergear: The turbo currently on my car has "apparently" got the same model number "0000029" as the demo one they gave the mechanics a number of years ago.. and the turbo that is on my car was also made a number of years ago...

SO NOW THE TEST... I worked out=

I said to the mechanics:"are you 100% positive this is not the turbo you showed me with the chip?" they looked me right in the eye and said: "no....take off the intake pipe and check it yourself"

so tommorow I will take off the intake pipe to the turbo... I will check the fins... if any single one is chipped I am going to give hell to the mechanics for lying right to my face!

if it is fine then hypergear should not make accusations ...

We will see..

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
