I think he means turbos with ceramic ball bearings.

since when does mazda use ceramic in their twins?

never heard that one before. . .

Exactly- I have ceramic coating on my stock twins, but it cost $$$$$$$$$$ to have Pettit do it.

 

did it make any noticeable diff?

BTW, this is rotorbrain. . . im at a friends house.

 

i wish those turbos were ceramic stock..

i meant the turbos themselves to be ceramic.. anyone heard of it??

 

Aerodyne Dallas makes a "Type IV" ceramic ball-bearing Aerocharger turbo (for the Miata) but Aerodyne is closed at the moment due to a patent dispute.

Rotorbrain- Pettit turbos spool faster, but that has nothing to do with the ceramic. They radius the internal flow passages to make the path more streamlined. Ceramic is to resist the effect of heat to reduce heat cracks from forming.

 

i'm not looking for ceramic coated...

i meant like the j-spec 3s-gte for the mr2 turbo (sw21).. their turbo is a ceramic ball bearing i think.. i'm not totally sure about the ball bearing but i do know that its ceramic.

 

These are all different things:

- ceramic coating of exhaust manifold and/or turbine housings
- ceramic turbine wheel (a la Buick GNX)
- ceramic ball bearings (presumably ball bearings with ceramic ***** and/or races instead of steel)
- ceramic coffee mug

Yeah, but is that a factory or aftermarket ceramic mug? I have a friend that knows a guy, whose sister's 3rd cousin, had his plastic McDonald's coffee mug ceramic coated. Keeps coffee hot for 10 or 12 days! Much longer than a factory ceramic mug, and lighter too!!

 

The STOCK 99+ Mazda Twins on the 280hp 13bREW's have an ABRAIDABLE CERAMIC coating to improve effeciency, the Base/Auto models w/260hp dont get the ceramic coating.

 

i meant the turbine wheel being ceramic...


i never heard of ceramic ball bearings.. but if they're out there i'd be interested in those too..

anyone know of it???

 

turbonetics offers garret turbos upgraded with 1 rolling element bearing that also takes thrust (metal races and ceramic *****), and one regular sleeve bearing. doubt it's avail for FD.

the garrett gt turbos use all metal ball bearings, both ends.

I recall nissan had a ceramic turbine wheel, not sure. unusual oem option.
