For anybody thinking of getting a Momentum 40T turbo...

Well, these turbos were reputed to be made in the United States which was later proven to be a bold faced lie. They are evo 16G clones made in Taiwan. Nevertheless, people still started using these turbos after being warned that there was no data about their longevity. Here's an interesting thread on Nasioc about how some of them are holding up:

I'm sure glad I didn't order one. I feel very safe with my 18G purchase from Forced Performance.

It sucks it caused the owners so much trouble for the "proof" that their turbos are no good. At least the information is out there and only the people who still don't do their homework before a big buy like this will pay the price. I guess someone had to be the guinea pig.

yea, it was mine that seized. Still exchanging emails trying to prove it was the turbo that went bad, and not my car that messed it up.

If you really want to get the same performance but have a reliable turbo. Just get a forced performance 16G with an evo III compressor wheel. that will run you $699 plus $145 for the wheel. Total of about $850. From everything that I have read, the 40T is a taiwanese knockoff of the EVO III 16G.

Do a little research on the TD06-20G. It's supposed to be an excellent turbo for the 2.5l.

Momentum and Nasioc "perons" have been having an on going struggle because of competitors talking this kinda crap....The guy that posted the pictures NEVER contacted Brian for a warranty claim, and if his turbo got SUPER LOUD, perhaps he should have taken it off the car and sent it in for analysis? Most turbo problems are OIL problems-the Subaru head is notoriously slow to lubricate upon startup (cold startup). Everyone knows that a good way to trash a subie head is to start your car in the morning, rev it up, and go. You do this one time, no harm no foul. You do this every day for a year, you have problems. Same thing with a turbo-in fact, the turbo oils from the head on those cars. The turbo draws oil from the cylinder head!

The bottom line is you CANNOT operate a turbo immediately upon
Startup; if you do, you have a problem. If you operate the turbo immediately upon startup EVERY TIME, your problem turns into a turbo failure. If you have an oiling problem with your EJ207 engine swap, same results. A turbo is a very fragile assembly-you starve it of oil once, you damage it. You starve it of oil for its entire life, it WILL fail.
I know a lot of people on NASIOC don't know this-that makes sense
because they have regular jobs. They are not turbo techs; they don't work in aerospace on jet engines, etc. They don't know how bad a turbo failure can be, and they can logically assume that the turbo is to blame because they don't know the factors

I would like for the guy to send his turbo to me/Brian for analysis, but he won't even return emails, so I guess that's that. It is important for us to analyze EVERY turbo failure that exists so that we can make sure it has nothing to do with what we are trying to accomplish. If there is a problem with our assy. process, we need to find it and fix it!
