subject Re: 2 Blown FP Turbos
Robert,
Thank you for the reply, and while I apologize for not replying to you sooner, I appreciate the effort you are making on my behalf. I do,
however, still have a few lingering questions that I hope you can provide answers for.
I would like more pictures of the failure areas on both of the turbos with their respective explanations as to how the observable damage was caused and what indicated this to you. I would appreciate that very much, and so would the members of the site. Thank you in advance.
You are not the only person to see the FP20Gs fail on the exhaust side. It seems that other members of IWSTI have posted a few threads in which their FP20Gs also failed on the exhaust side. It appears that there may be something else wrong other than the possibility of particulate matter, perhaps with the turbos themselves being that it is not likely to have all these cars firing particulates big enough to break exhaust turbine fins off the turbos, yet have no damage anywhere else on their cars. To make things more confusing to me, you were unable to find any particulates in the housing of the 20G, other than the broken turbine fin, and there was nothing else in the catalytic converter in my car - as XX has removed it and other components of my car to inspect it for damage after the 20G failed.
Also, you were correct, I still have the OE exhaust manifold on the car, along with new gaskets every time I had to pay for the
installation of an FP turbo. I can assure you that no expense was spared when it came to providing the best for my car, since it is my
daily driver car and of course, because I like the car. I had the car for about 2 years and 19,000+ miles before it was modified in any way, at which point it was always with the OE turbo. Only around the 30,000+ mile marker did I decide to add power to the car beyond the OE turbo, at which point I had the FP 20G installed. That turbo lasted less than a year. The Green turbo lasted less than 2 months. Today, the car has less than 44,000 miles. The two FP turbos combined lasted less that 14,000 miles. I can’t see how that is possible when the OE turbo tuned past factory power levels has lasted over 122,000 documented miles for one member on IWSTI and these turbos were not tuned past their specifications. Perhaps you can tell me where else should I look for extraneous matter of the size required to cause the damage you describe? I’m sure my tuner would also like to know for the sake of their future customers.
I am extremely fortunate that your turbos didn’t destroy other parts or even the rest of my car (although I did pay for the tests to be
sure), because I can see that your warranty would really do me no good in that event. Your warranty would apparently leave me with a new FP turbo and a $33,000+ car that couldn’t bring me to work.
The speculative cause for failure of the Green didn’t sit well with me being that the factory VF39 is not, in fact, a ball bearing turbo, but
as per Subaru and IHI literature, is a thrust bearing turbo. If my Amsoil 10W-30 motor oil was (and is today) able to provide the OE IHI
turbo with sufficient pressure to float the thrust bearing, and the same held for the 20G’s bearing, why now can it not provide the Green
with enough pressure? The car consistently sees a minimum of 20 - 22 PSI pressure when the oil temps are at their max, and under load the oil pressure is at a minimum of 70 - 71 PSI. If your Green turbo requires a different grade of oil and/or different pressure than the
factory thrust bearing turbo, why wasn’t this noted on the FP site or literature at any time prior to his email? I would be saddened to
think that my car was an unwilling and expensive R&D subject.
Again, thank you for the time you have put in and the care you have shown in answering my emails. As a loyal customer who bought two
turbos from you I expected no less. If you could provide me with these answers I would greatly appreciate it; not to mention all the
hundreds of potential customers on IWSTI.com who will be made aware of my problems. The faster we can speed this to a satisfactory
conclusion, the happier we will all be in the end.
Regards,
Jason

subject Re: 2 Blown FP Turbos
I am unable to continue exchanging emails regarding turbo failure modes, I have explained what I see in these 2 turbos. I appreciate your curiosity and interest in this subject. It is not fruitful to entertain hypothetical possibilities regarding the failure of these two turbos any further. I know it seems cliche, but I have perhaps the most experience of anyone in the country when it comes to Mitsu based hybrid turbos and what it takes to make them live and what results in their failure and the opinions of untrained forum readers is not particularly relevant to the truth of this matter. I am correct regarding the failure of your 2 turbos, it is not something that is debatable. The 2-3 fold increase in oil flow required by the monster thrust bearing of the Green and red models makes them susceptible to oil starvation, omitting the stock oil line and using our recommended feed line is all that is required as far as additional parts to provide proper lubrication so long as there is nothing unusual with the balance of the oil system of the car. You did this, which is why we can cover the turbo under our warranty. Additionally, intercooled engines are not harmed during the failure of a turbocharger, even in the severe case where the compressors explode. None of these pieces can pass thru the intercooler, and in the case of a broken turbine wheel, all pieces continue to travel downstream in the exhaust. So your concerns over engine damage are unwarranted. I am not optimistic that you will avoid hammering FP on the internet about your blown up turbos, you have hinted to such in ever correspondence to date. Despite that, please make a reasonable request for compensation and I shall consider it due to your bad experiences even though our warranty does not allow for such compensation. I regret that you have had such a poor experience with our product and wish to make it up to you.
If you wish to discuss this further, feel free to call me. 972--* ext ***

Its these two exchanges which tell me FP knows they f*ucked up. The bold is what makes me think, (again im just merely playing devils advocate here) that that if FP saw what would be reasonable compensation assuming they did sell these “faulty turbos,” that $2600 is a lot to dish out and not a price they wanted to pay.
In response FP came up with that next email, which in my head is just them hitting the eject button on this confrontation. Whats worse is as Majin threatens further, FP gives in a little (which again to me is a sign of them admitting guilt).
Im no tech guy, but the bolded above does not seem to sit quite right in my head and with FP now being in possesion of the turbo and the holders of the ultimate tech knowledge, I can just find it easy for them to fabricate any “reasonable” excuse to the end user as to “why its not their fault.”
If someone on these boards (probably inntune or carnut) can verify that these tine metal splinters actually do splinter off and cause the damage correlated to those pictures than ill just shut up. But this tells me its more than that. (either majin trying to scam here or FP screwing up in manufacturing)
Again im not saying Majin is right. Im just saying I think some here people are not being deductive enough.
