 ===== Other Considerations on Turbo Selection =====
+==== Bearings ====
 Generally most older turbochargers will use a journal bearing that only requires oil to lubricate and cool the bearings.
@@ Line 40: / Line 42: @@
 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.
+==== Compressor Wheel ====
 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 housing. However there a lot of other things that play a big factor here as well.
+Other main factors that can improve spool times are:
+  * variable vane technology usage
+  * twin-scroll turbine housings
+  * size of the turbine housing and turbine itself
+  * A/R ratio of compressor and turbine housing
+  * camshaft selection
+However there a lot of other things that play a big factor here as well. This are just some of the more commonly discussed heavy hitters.
