THATS ABSOLUTELY CRAZY

 

I agree!

 

For option C can you hang on to those brakes for me

 

ANOTHER REaSON WHY TN SUCKS ***.

People just dont listen. jeez

Im saving this thread.

 

why?
...quality...hmm

....marketing... maybe....

 

im surprised the TN god hasnt posted here yet.
if TN turbos were so nice why would there be so many hateful annoyed customers?
and you wont be unhappy with the hks kit with twin Garret gt-28-rs.
and good luck!

 

actually i am looking at getting some Garret GT-28's.

I already have a TT kit so i would be set after this

 

you cant go wrong man JT hooked it up.

 

Honestly I've seen so many Turbos reduced to afterburners because of bad oiling. I can't tell you how many times I've seen someone forget to install a return line of the manufacturers suggested size or forget to install a reducer in the main feed. Especially on low mount turbos like on the VG cars. Turbos happen to make very poor quality oil sumps.

Turbonetics turbos are just fine, they aren't as large as they are for making **** turbos that break all the time. I've seen this exact same thing with Greddy Twins on these cars, and numerous Honda/Subaru singles. Just because the manufacturer doesn't come back and tell you that you did it wrong, doesn't mean you should double check things and stick to what the manufacturer recommends.

We did one car that is on the boards running fine now with the greddy twins kit, installed elsewhere and had killed both turbos once before we got it, and a single after we got it. The shop that installed it decided bigger is always better and put bigger hoses on it than came with the kit. We didn't realize it till after the one side died while it was at our shop. The customer luckily wasn't in a huge hurry, but what a PITA all because someone replaced a part.

 

Everything that was used (line, etc.) was what was provided by Speed Force Racing and the kit was initially Installed by Forged Performance. Jeremy Reinstalled everything the way it was before and now the same problem. Thats two of the most respected shops on this board that haven't been able to get these suckers to work.

 

Being the amount of failed TN turbo threads I've seen on the forum, I doubt all of them are installation problems

 

That seems odd, but like I said, in my experience all the turbos that I've seen failed were because of install. I'd double check the lines and parts with Turbonetics to make sure the kit didn't ship with incorrect parts, I had a Precision turbo ship with the wrong fitting once and it ate itself up before the car got strapped to the dyno. Manufacturers fault yes, but should have been checked before install.

 

i just wonder who legitimately covers the labor to fix issues like this.


everyone can point fingers but at the end of the day, it needs to be done.

car is sitting here with a beautiful sounding brand new built engine with oil pouring out of the exhaust pipes... :/

 

So i guess your NO TURBONETICS policy is in full effect now???

 

HAHAHAHA

 

Sounds like the sump system is fine. My suspicion is that any turbo you put on there will fail. What kind of oil restrictor does the SFR kit use? Before ditching the turbos, I'd try restricting the oil feed line (try the JWT restrictor?) and switch to a heavier weight oil. The seals may be damaged now but it'd be a quick experiment and if you detect a noticeable improvement, then I think you'd be on to something. What's the worst that could happen? Damage to the turbos? They're already useless the way they are.

 

 

**** happens - split it evenly b/w shops and customer? A shop has to recover costs at least to survive. TN has already rebuilt once. I'm not biased to any shop or sponsor in this thread and based on the data presented, this seems to be a design issue stemming from the low position of the turbos. The kit addresses the problem, but perhaps not well enough. While the turbos are leaking oil, I'd put a pressure gauge on the oil feed line and ask TN what pressure range is recommended for that particular turbo. My understanding is that for most turbos it is around 30 psi max to 10 psi min. That way you at least know if the next set of turbos will also fail... I've always thought that a better alternative to a restrictor is a pressure relief bypass valve - not heard of any kits that run such a thing though.

Bad situation all around - good luck guys.

 

Yeah thats the PITA in all this. Sometimes you just have to suck it up and make the customer happy, hopefully communication is open between you and the manufacturer though, often that helps things move along.

We're kind of use to it here, it seems besides development all we do is repair other peoples work or install other peoples product. Invariably it costs more for us to fix it rather than doing it right the first time, but thems the breaks. We try and double check everything before installing but thats not always possible and we're very upfront and honest with customers, if something is wrong, it's wrong. If it costs X amount to repair it then thats what it's going to cost and we're not going to do it wrong. Luckily most of our customers understand and in the long run they're very happy with the outcome.

 

Any Turbonetics turbo??????


We are going to try switching out the pump and use some restrictors. If that doesn't work then it is on to some different turbos.

BTW we are using 20w 50
