Hi Blue ,
L24 vs S20 , both are wonderful engine.
We need to be specific about what we are going to compare with them . Generally speaking ? Or racing cars ? L24 Europe vs US and Canada , etc etc .
We can’t say like this , “ S20 has less torque so Z432 is inferior car in S30 family “ .
Nissan works race car used a racing L24 , but we can’t say like this, “ showroom L24 engined car is superior than Z432 “ .
We can’t say “ our US and Canada Datsun 240Z is superior than Z432 “ only relying a comment of the racer and a fact that Nissan works team took L24 rather than S20 . Racing history , results , came from a lot of complicated back ground. It is not that simple .
You may say S20 in a works Z432-R had a terrible transmission vibration, yes some racers mentioned it .
But that doesn’t mean S20 is a bad engine , Z432 is a bad car . Keeping the rev not below 6000 rpm , and sometimes using 10000rpm quite often in racing S20 Z432-R , it is obvious that transmission could have the trouble more likely than L24 racing car .
L24 , thanks to the torque, it didn’t need that much rev .
And , L24 is easy to maintain , S20 needs much more hands to set the valve adjustment accurately.
L24 is easy drive too , so rally cars have L24 for its endurance, various kinds of road conditions.
If we want to know what was going on , we need to hear , talk with many people who were involved Nissan , engineers , designers, racers , mechanics, in Japan like Alan has been doing . Time is running out, they are all became old .
I can sympathize with you about trying to look down S20 and Z432 because I was doing same thing 20 years ago.
Just one experience changed whole my idea , my understanding . Mr. Yoshida’s Z432 opened my eyes wider than the past days .
We can’t hate it without driving it , owning it .
