Message: <blockquote data-quote="SDF" data-source="post: 3209828" data-attributes="member: 546">well well...to correct some facts :1. GT Ball Bearings are now repairable. Genuine Garrett ball bearing cartridge ex-stock and ready to ship. Don't let old info block your vision, Call our dealers for more info.[ATTACH=full]657336[/ATTACH]2. Holset has many wheel trims and sizes as well. HX 35 to HX 40 there are easily 5-8 wheel sizes. :hmmmm:3. HX series has many turbine housing sizes as well...so do some homework before getting one. :hmmmm:4. Garrett GT series run over 2.5bar with ease and requires less oil and has less heat soak back. Ron Lumus (Garrett sponsored) in his Drag cars run up to 60psi with GT4718R's...no reliability issues.5. Brent Rau swaps a turbo after every event. (reliability ?) and his configuration is RWD tube frame revving to 13k RPM and the Borg Warner doesn't even build boost till past 7k RPM.6. Yup repair kits are cheap for Borg Warner and Holset, but fact is also, if "thrust play" comes into the turbo, it's a goner as well...no difference from any other brand of turbo. <img src="https://zerotohundred.com/forums/styles/default/xenforo/smilies/nurse.gif"  class="smilie" loading="lazy" alt=":nurse:" title="Nurse    :nurse:" data-shortname=":nurse:" /> 7. Garrett GTBB turbos don encounter "thrust play" hence the only time it fails is due to :- engine failure, leading to no oil supply- extreme heat soak back (water lines must be run)- foreign object / particles impacting the wheels (turbine or compressor)or else....it'll last a hell longer than most journal bearing turbos.Anyway it's good for others to opt for something exotic or weird or new to try. My point is, to ensure a healthy motorsport community and to correct facts as far as we can. Myths don't carry weight...Facts do.. <img src="http://zerotohundred.com/forums/styles/default/xenforo/smilies/burnout.gif"  class="smilie" loading="lazy" alt=":burnout:" title="Burnout    :burnout:" data-shortname=":burnout:" /></blockquote>
