Precision, Borg-warner, Garrett are trusted companies in the turbo game and even manufacture oe-applications as well. All 3 are good and make solid products lasting thousands of kms...what'll decide how long your turbo lasts is if one it's sized properly(not over-speeding the compressor or surging/chugging), reasonable egt's, an adequate clean FILTERED oil supply @ the right psi, good plumbed oil return, waiting until the oil is warm before seeing boost etc etc....there are turbo's that last years and some that last for just a month...all comes down to how great (or not great) the turbo selection, installation, driving habits, oil used, oil change frequency and a whole ton of other things.

Sounds like you need to do some real research and understand things so YOU can select the right turbo that YOU want for YOUR application instead of basing your decision off some youtube videos....start with this:

i mostly use precision turbo's, never had a problem with them. i love the 6262 its a great turbo. but you need to know what your goals are before choosing a turbo, because every turbo is different.

Comp turbo oiless turbo ftw. No need for a scavenge pump anymore. I grabbed mine from a dealer for a wicked price. Billet and ball bearing.

Ive also noticed a lot of these being used on V8's in rear mount turbo kits. Might consider doing that also since I dont need to run a pump.

Uhh...not really ftw....I've already heard about 3 of these turbos failing on various BMW applications...all sent back to comp switched for regular journal and ball bearing CHRA's*wave*. I'll stick to oil fed/drained turbos..it is a great idea however if they have a longer service life..

As long as its sized properly and you make sure the oil supply will never run dry, or cook after you turn the car off... I've heard good things about Borg-warner and Garrett. Look at it this way they can't really be made bad or they just won't work, spinning above 150000rpm they would just explode, any oem one should be good, ied avoid ebay ones

Technology wise look for a ball bearing one that takes a external wastegate and has a ceramic turbine. They will require more to rebuild should it need it, but there's less friction and better flow *th-up*

Post up the links. I would be curious to know who has had an oiless failed on them.

Thanks for the info. Man I searched and searched for failures. Seen a lot of success with the oiless units but could not find any failures. I guess its the odd couple that might fail since QC is never 100%. Hopefully Comp got it sorted for the customers.

For me it was either the oiless or a pte unit which has way more than 2 reported failures. Decisions decisions, I still think im going to go slap on this oiless though. Saves headache and comes with a warranty. Thanks for the links again.
