Twin Dizzy 12A????
 
What car/cars and years did the twin dizzy 12A come in?

bumpstart 05-13-10 11:20 PM

depends on the market ,, but generally 1973 is the end of the twin dizzy engines and start of the singles is 1974 year

US markets may be a little different but thats generally the rule

ie in australia 12a TD is found in LA22s ( rx4 sedan 1973 ) and also 1973 rx2 ( S122A ),, while the rx3 had the 10a ( S102A ) twin dizzy
( i believe the US rx3 linage is different )

1974 brings all single dizzy engines
LA23S ( 13b rx4 )
S122A ( still ) rx2,, but with a 12a SD
and S124A for the new 12a SD rx3

In the US it was used in the RX2 and RX3. Like bumpstart said the last year was 73

Bill you been looking at my NOS twin dizzy 12a, haven't you?

That particular engine is actually a J-spec 135hp engine
