Out of the 1UZ 2UZ 3UZ which heads flow the best?
Are all these heads interchangable between all blocks?
Between the 1UZ and 3UZ is the 1UZ block stronger/beefer?
Finally what year 1UZ or 3UZ did they start using coil on plug ignitions
I noticed the current Lexus GS430 makes more HP and Torque then the 2UZ granted its not low end grunt..but its strange that it is smaller and produces a higher peak torque.
Thank you for any information on this.
