 Generally most older turbochargers will use a journal bearing that only requires oil to lubricate and cool the bearings. Generally most older turbochargers will use a journal bearing that only requires oil to lubricate and cool the bearings.

 A ball-bearing turbocharger with a billet compressor wheel will spool faster and have more room to make power than a similarly sized journal bearing turbo. A ball-bearing turbocharger with a billet compressor wheel will spool faster and have more room to make power than a similarly sized journal bearing turbo.

 Some turbos will also have billet aluminum compressor wheels that will help speed up the spool times due to the decrease in rotating mass. Some turbos will also have billet aluminum compressor wheels that will help speed up the spool times due to the decrease in rotating mass.
  
-Other main factors that can improve spool times are variable vane turbos, ​twin-scroll turbine housings, and size of the turbine housingHowever there a lot of other things that play a big factor here as well.+Other main factors that can improve spool times are
