So when you fit the next D4 Cat engine upgrade
@Claviger you may need the upgrade versions available from even yours. By reading the special notes re alternates I found that :
- The standard version for the Aussie equivalent Toyota Camry 4Cyl 2000cc was only 1.2Kw
- There are stock 1.4 Kw versions for some models; and
- 1.6Kw upgrades for 4WD or commercial vehicles.
The latter 1.6Kw version is an intriguing
PMGR starter which have no field coils like positive-engagement starters do. This means that power is sent directly to the starter armature through the brushes and commutator, meaning less battery power is wasted energizing the field coils and that less heat is generated by the starter as well.
Lots of great info here re starter motors and torque and performance.
The higher torque starters are specifically designed for 16:1 and higher compression ratios and are not really designed for use in your stock or slightly modified street car. You could end up buying too much torque and spending too much money. Although a 200-lb.ft. starter will work fine in any application, your standard small-block engine will only require 160-lb.ft. if the compression ratio is less than 11:1, or 180-lb-ft. if the compression ratio is higher than 11:1. There seems to be a lot of marketing of PMGR starters by kilowatt ratings. Most are advertised between 1.4kw to 2.0kw, but don't be deceived by the kilowatt rating. Two starters sitting side by side and advertising 1.7kw can have different torque specifications.
